For teeth whitening strips for sensitive teeth, my best overall pick is Crest 3D Whitestrips Sensitive White At-Home Teeth Whitening Kit, which offers a dedicated sensitive-teeth format and 18 treatments. Lumineux Peroxide-Free Teeth Whitening Strips are a standout for shoppers who want to avoid peroxide, while Pdoo Purple Strips suit people focused on temporary color correction rather than traditional whitening. The main tradeoff is between peroxide-based kits, which target stains more directly but may trigger sensitivity, and peroxide-free or purple options, which take a different approach and may deliver subtler or less lasting results. Fit, wear time, and treatment count also affect how manageable a routine feels. Read on for the full comparison and help choosing the type that fits your teeth and expectations.

Key Takeaways
- Crest Sensitive White with 18 treatments leads the lineup for shoppers seeking a dedicated sensitive-teeth kit and a longer treatment supply than the 14-treatment Crest option.
- Lumineux’s peroxide-free formulas stand apart from the Crest kits by avoiding peroxide, making them a distinct option for buyers who prefer a gentler-feeling approach over a conventional whitening formula.
- The two Lumineux pack sizes serve different needs: the 9-treatment version gives cautious buyers a shorter commitment, while the 21-treatment pack supports a longer routine.
- Purple strips are not the same as stain-removing whitening strips; Pdoo and the mint 14-strip option are better suited to buyers seeking a color-correcting effect than those expecting traditional whitening.
- GuruNanda’s 7-day and 16-day kits offer different routine lengths, while the larger-count generic and InoPro options make formula details and instructions especially important to check before choosing.

More Details on Our Top Picks
GuruNanda Teeth Whitening Strips, 7-Day Kit
Two treatment formats make this GuruNanda kit a more flexible pick than Lumineux’s peroxide-free strips, which focus on a gentler formula rather than offering express and professional options. It contains five professional and two express treatments, giving buyers a way to vary the routine while targeting stains from coffee, wine, or smoking. The dry strips are designed to stay in place for up to 60 minutes, which may suit someone who prefers a longer application, but it also asks for more time than Pdoo’s 30-minute strips. Hydrogen peroxide can be a drawback for people who know peroxide triggers their sensitivity; coconut extracts do not make this a peroxide-free option. I’d choose it for flexibility, not for the shortest or most cautious sensitivity-focused routine.
Pros:- Includes five professional and two express treatments
- Covers both upper and lower teeth
- Dry-strip format is designed to adhere for up to 60 minutes
- Vegan formula
Cons:- Contains hydrogen peroxide, so it may not suit people who are peroxide-sensitive
- Professional applications can take up to 60 minutes
- Product information does not provide independent results or user outcome data
Best for: People with occasional sensitivity who want both express and longer professional treatments for common food and drink stains.
Not ideal for: People who react to hydrogen peroxide or cannot set aside up to 60 minutes without eating, sleeping, or smoking.
- Formula:Dry strips with hydrogen peroxide and coconut extracts
- Kit contents:7 treatments: 5 professional and 2 express
- Coverage:Upper and lower teeth
- Wear time:Up to 60 minutes
- Vegan:Yes
- Facility claim:Made in an FDA-registered facility
Our verdict“Choose this kit if you want two treatment formats and can tolerate peroxide, but pick Lumineux if avoiding peroxide is your priority.”
Lumineux Peroxide-Free Teeth Whitening Strips, 21 Treatments
For buyers focused on limiting sensitivity triggers, this is the strongest fit in the group: its peroxide-free formula is described as suitable for sensitive teeth and veneers. The 21 treatments provide a three-month supply, a longer routine than Lumineux’s nine-treatment version and more opportunities for steady use. Its mineral-rich, coconut oil-based ingredients target stains from coffee, tea, and wine, though the supplied details do not establish how much whitening to expect. Compared with Crest’s Sensitive & Gentle kit, this option skips the peroxide-based positioning and LED step, but it also lacks that kit’s defined 14-day schedule. I’d favor it for people who want a gradual, peroxide-free approach and are comfortable with less evidence about results.
Pros:- Peroxide-free formula designed with sensitive teeth in mind
- Listed as suitable for veneers
- Provides 21 treatments, described as a three-month supply
- Free from SLS, artificial colors, and artificial flavors
Cons:- No independent test results or expected whitening outcomes are provided
- The product details do not specify application time or a detailed treatment schedule
Best for: People with sensitive teeth or veneers who want a longer peroxide-free supply for routine coffee, tea, or wine stains.
Not ideal for: Buyers seeking a clearly timed whitening course or those who want published independent results before choosing a product.
- Treatments:21
- Supply duration:3 months
- Formula:Peroxide-free
- Key ingredients:Mineral-rich, coconut oil-based actives
- Free from:Peroxide, SLS, artificial colors, and artificial flavors
- Suitable for:Sensitive teeth and veneers
- Cruelty-free:Yes
Our verdict“Pick the 21-treatment Lumineux kit if you want a longer peroxide-free routine for sensitive teeth or veneers and do not need a defined course schedule.”
Lumineux Peroxide-Free Teeth Whitening Strips, 9 Treatments
This smaller Lumineux pack keeps the key appeal of its 21-treatment counterpart—a peroxide-free formula—in a shorter, one-month supply. That makes it a more contained choice for someone who wants to try a peroxide-free routine before committing to the larger pack. The tradeoff is straightforward: there are only nine treatments, compared with 21 in the longer Lumineux kit, and the supplied product details do not specify ingredients beyond being peroxide-free, an application schedule, or suitability for veneers. Crest’s Sensitive & Gentle kit offers a more structured 14-day plan, while this version leaves more questions about routine and expected results. I’d treat it as a trial-size option for peroxide avoidance, not as a well-documented whitening program.
Pros:- Peroxide-free formula
- Nine treatments in a one-month supply
- Shorter commitment than Lumineux’s 21-treatment pack
Cons:- Fewer treatments than the 21-treatment Lumineux version
- Product details provide little information about ingredients or application time
- No independent results or expected whitening outcomes are supplied
Best for: People with sensitivity concerns who want a one-month, peroxide-free trial before choosing a longer supply.
Not ideal for: Buyers wanting a three-month routine, detailed ingredient information, or a clearly stated treatment schedule.
- Treatments:9
- Formula:Peroxide-free
- Supply duration:1 month
- Product type:Teeth whitening strips
- Application time:Not specified in the supplied product data
- Key ingredients:Not specified in the supplied product data
Our verdict“Choose this pack for a shorter peroxide-free trial, while the 21-treatment Lumineux kit is a better fit for a longer routine.”
Pdoo Purple Teeth Whitening Strips for Sensitive Teeth, 28 Count
Pdoo’s main advantage for sensitivity-conscious buyers is its 30-minute application, which is shorter than GuruNanda’s professional strips, worn for up to 60 minutes. The brand describes the strips as designed for sensitive teeth and uses PAP+ technology with a moisture-activated dry-gel seal to target stains from coffee, tea, wine, and smoking. Secure adhesion may make it easier to keep the strips in place during the session, but the product still calls for consistent use over seven to 14 days for its stated optimal results. Those timing and result claims come from the seller, not independent evidence in the supplied details. Compared with Lumineux, Pdoo offers a shorter specified application but does not provide the same explicit peroxide-free positioning.
Pros:- Designed for sensitive teeth
- 30-minute application is shorter than GuruNanda’s professional treatment window
- PAP+ technology targets common food, drink, and smoking stains
- Dry-gel seal is designed to help strips stay in place
Cons:- Seller says optimal results require consistent use for 7 to 14 days
- Visible-result claims are not supported by independent results in the supplied details
- The supplied formula details do not state whether the product is peroxide-free
Best for: People who want a defined 30-minute application and strips designed for sensitivity, with a week or more available for consistent use.
Not ideal for: Buyers who need a clearly stated peroxide-free formula or want independently documented whitening results.
- Count:28 strips
- Technology:PAP+
- Application time:30 minutes
- Adhesion:Moisture-activated dry-gel seal
- Designed for:Sensitive teeth
- Targeted stains:Coffee, tea, wine, and smoking
- Seller-stated routine:7 to 14 days for optimal results
Our verdict“Choose Pdoo if a 30-minute session and sensitivity-focused design matter most, but select Lumineux if peroxide-free labeling is a requirement.”
Crest 3DWhitestrips Sensitive & Gentle Teeth Whitening Kit with LED Light, 14 Treatments
Crest gives buyers a clearly timed course: 30 minutes with the strips, followed by five minutes with the LED light, repeated daily for 14 days. That structure is more prescriptive than either Lumineux peroxide-free pack, whose supplied details do not give a daily application schedule. The kit is described as designed for teeth sensitive to whitening and enamel safe, while its no-slip grip is meant to keep strips in place during each session. The cost of that guided routine is time: at about 35 minutes per treatment, it asks more of the buyer than Pdoo’s 30-minute application. The light adds a step rather than removing one, so I’d choose Crest for people who value a defined process and can stick with it—not for anyone seeking the simplest routine.
Pros:- Designed for teeth sensitive to whitening
- Includes an LED accelerator light
- No-slip grip is intended to keep strips in place
- Includes a 60-day satisfaction guarantee
Cons:- Requires daily use for 14 days
- Each treatment takes about 35 minutes
- The LED light adds a separate step after wearing the strips
Best for: People with sensitivity to whitening who prefer a structured daily plan and can commit about 35 minutes a day for two weeks.
Not ideal for: Buyers who want a peroxide-free formula, a shorter application, or a routine without an additional LED step.
- Treatments:14
- Strip count:28 total: 14 upper and 14 lower
- LED accelerator light:1
- Daily strip time:30 minutes
- LED use time:5 minutes after strips
- Formula description:Designed for teeth sensitive to whitening; described as enamel safe
- Satisfaction guarantee:60 days
Our verdict“Pick Crest for a structured 14-day routine with an included light, but choose Pdoo if you want a shorter session without that extra step.”
Teeth Whitening Strips for Sensitive Teeth, 28 Count
For a straightforward 30-minute daily routine, this kit offers 14 applications aimed at stains from coffee, tea, cola, and smoking. Its moisture-activated gel and non-slip design are intended to help the strips stay put while you wait. Compared with Crest 3D Whitestrips Sensitive White, it has a shorter stated course, but the provided details do not cite the same ADA acceptance or enamel-safety claims. The main tradeoff is that the description gives no ingredient details, so shoppers who want to avoid particular whitening agents have less information to work with. Visible change is also presented as dependent on consistent use, with no supporting evidence included in the product information. I’d pick it for a basic, stain-focused routine, not for the clearest ingredient disclosure.
Pros:- Designed for teeth described as sensitive
- Non-slip design aims to keep strips in place
- Targets stains from coffee, tea, cola, and smoking
- Each application takes 30 minutes
Cons:- The product information does not identify the whitening ingredients
- Visible results depend on consistent use and are not substantiated in the provided details
Best for: People with sensitive teeth who want a simple 14-use routine focused on everyday drink and smoking stains.
Not ideal for: Shoppers who need ingredient transparency or want a whitening option with specific safety credentials stated in the product details.
- Count:28 strips
- Sets:14
- Intended use:Teeth whitening and stain removal
- Designed for:Sensitive teeth
- Application time:30 minutes per use
- Stains targeted:Coffee, tea, cola, and smoking
- Strip design:Moisture-activated gel and non-slip design
Our verdict“Choose this kit for a simple 14-application routine, but compare its limited ingredient disclosure with Crest Sensitive White before buying.”
InoPro Peroxide-Free Teeth Whitening Strips, 14 Treatments
InoPro is the clearest choice here for buyers who want to avoid peroxide: its peroxide-free, alcohol-free, and SLS-free formula uses bearberry extract, green antioxidants, and coconut oil to address the appearance of surface stains. That gentler positioning sets it apart from GuruNanda’s 16-Day Whitening Kit, which contains hydrogen peroxide and offers both professional and express treatments. InoPro instead asks for daily use over 14 days, so it suits people willing to follow a steady routine rather than seek a more intensive bleaching-style approach. The shade guide gives users a way to track changes, though the product details describe surface-stain brightening, not removal of deeper discoloration. I’d favor it for ingredient preferences and a measured approach, while buyers wanting stronger whitening claims should look elsewhere.
Pros:- Peroxide-free, alcohol-free, and SLS-free formula
- Includes bearberry extract, green antioxidants, and coconut oil
- Shade guide helps track progress
- Designed for daily use with sensitive teeth
Cons:- A 14-day daily routine takes commitment
- Positioned for surface stains rather than more intensive bleaching
Best for: Sensitive-to-whitening buyers who specifically want a peroxide-free, alcohol-free, and SLS-free formula for surface stains.
Not ideal for: People seeking a short course or substantial change to deeper discoloration, since the product is positioned for surface stains and requires 14 daily treatments.
- Treatments:14
- Strips:28
- Formula:Peroxide-free, alcohol-free, and SLS-free
- Featured ingredients:Bearberry extract, green antioxidants, and coconut oil
- Flavor:Coconut mint
- Included accessory:Shade guide
- Routine:Daily use over 14 days
Our verdict“Pick InoPro if avoiding peroxide matters more than pursuing a shorter or more intensive whitening course.”
Purple Teeth Whitening Strips for Sensitive Teeth, Mint, 14 Strips
With seven treatments, this is the shortest routine among these five, making it a lower-commitment way to try strips designed for sensitive teeth. Each mint-flavored application is intended to stay in place for 30 minutes, and the product targets surface stains from coffee, wine, and tobacco. Compared with the 14-treatment purple Pdoo kit elsewhere in the roundup, this pack offers fewer applications; it may suit someone testing their tolerance, but offers less room for a sustained routine. The description calls the strips enamel-safe, yet that claim is not backed by evidence in the supplied details, and results may depend on regular use. I’d choose this for a brief trial and skip it if you already know you need a longer course or want more substantiated safety information.
Pros:- Designed for sensitive teeth
- Seven treatments provide a short trial routine
- Targets surface stains from coffee, wine, and tobacco
- Mint flavor and non-slip fit are specified
Cons:- Only seven treatments are included
- Each application takes 30 minutes
- Enamel-safety and effectiveness claims are not supported by the supplied product information
Best for: People with sensitive teeth who want to try a brief, seven-treatment strip routine for common surface stains.
Not ideal for: Buyers seeking a longer whitening course or independently substantiated enamel-safety details.
- Quantity:14 strips
- Treatments:7
- Flavor:Mint
- Application time:30 minutes
- Designed for:Sensitive teeth
- Fit:Non-slip
- Stains targeted:Coffee, wine, and tobacco
Our verdict“Choose this short-course kit to try sensitive-teeth strips, but opt for a longer pack if seven applications are unlikely to meet your needs.”
Crest 3D Whitestrips Sensitive White At-Home Teeth Whitening Kit, 18 Treatments
Crest makes the strongest case for buyers who want clearly stated backing alongside a sensitive-teeth formula: the kit is described as enamel safe and accepted by the American Dental Association. Its 18 daily treatments give it a longer course than the 14-use kit from B09X17H3WN, while the no-slip grip is intended to keep both upper and lower strips in place. That fuller routine may suit someone targeting years of stains, but it also means 30 minutes every day for 18 days. InoPro is a better match for shoppers avoiding peroxide, since Crest’s supplied details do not specify a peroxide-free formula. I’d rank this highest for buyers who value the stated credentials and are comfortable with the time commitment, rather than those seeking a brief or explicitly peroxide-free option.
Pros:- Formulated for teeth sensitive to whitening
- Product details state enamel-safe and ADA-accepted
- Includes strips for upper and lower teeth
- No-slip grip is designed to keep strips in place
Cons:- Requires daily use for 18 days
- Each treatment takes 30 minutes
- The supplied details do not identify the whitening ingredients
Best for: Sensitive-to-whitening users who want a longer at-home course with enamel-safety and ADA-acceptance claims stated in the product information.
Not ideal for: People who cannot commit to 30 minutes daily for 18 days or who specifically want a peroxide-free formula.
- Treatments:18
- Number of strips:36
- Application time:30 minutes daily
- Treatment duration:18 days
- Formulation:For teeth sensitive to whitening
- Safety:Described as enamel safe
- Association:Accepted by the American Dental Association
Our verdict“Choose Crest if you value its stated ADA acceptance and enamel-safety claims enough to follow an 18-day routine.”
GuruNanda Teeth Whitening Strips, 16-Day Whitening Kit
GuruNanda stands apart by combining 12 professional treatments and four express treatments, giving buyers two formats within one kit. It includes strips for both arches and uses a dry-strip formula with hydrogen peroxide and coconut extracts, aimed at stains from coffee, wine, and smoking. Compared with InoPro, it is the less suitable choice for shoppers avoiding peroxide; InoPro’s peroxide-free formula better fits that preference, while GuruNanda offers more treatment variety. The strips are designed to adhere for up to 60 minutes, which gives the routine a longer potential wear time than Crest Sensitive White’s stated 30 minutes. That flexibility comes with a meaningful commitment: users should not eat, sleep, or smoke while wearing them. The supplied details do not describe a sensitive-teeth formulation, so I’d be cautious if sensitivity is your main concern.
Pros:- Combines 12 professional and four express treatments
- Includes strips for upper and lower teeth
- Designed to target coffee, wine, and smoking stains
- Vegan formula with strips designed to adhere for up to 60 minutes
Cons:- Contains hydrogen peroxide and is not described as formulated for sensitive teeth
- Wear time can be up to 60 minutes
- Users are advised not to eat, sleep, or smoke while wearing the strips
Best for: Buyers who want both professional and express treatment formats and are comfortable using a hydrogen-peroxide formula.
Not ideal for: People who specifically need a formula described as suitable for sensitive teeth, want to avoid peroxide, or cannot wear strips for extended periods.
- Treatments:16 total: 12 professional and 4 express
- Strips per treatment:2, for upper and lower teeth
- Wear time:Up to 60 minutes
- Key ingredients:Hydrogen peroxide and coconut extracts
- Formula:Dry strips
- Product attribute:Vegan
- Manufacturing detail:Made in an FDA-registered facility
Our verdict“Pick GuruNanda for its two treatment formats, but choose InoPro or Crest Sensitive White if sensitivity or peroxide avoidance is your priority.”
How We Picked
I ranked these products around the needs behind the search: buyers want visible whitening but also want to limit the chance that treatment will aggravate sensitive teeth. I compared the stated formula approach, whether a product is specifically presented for sensitive teeth, treatment count and routine length, and practical details such as wear format or included accessories. A larger count alone did not earn a higher place; the formula and clarity of the product’s intended use mattered more.
The order favors options with a clear fit for sensitivity-conscious shoppers, then separates them by their tradeoffs. Crest’s dedicated Sensitive White kit ranks ahead of its LED bundle because the sensitive-focused kit offers a clearer, simpler match without making the light the main selling point. Peroxide-free Lumineux options follow for buyers who prefer to avoid peroxide, while purple strips rank lower for traditional whitening because color correction is a different goal. I treat products with limited formula detail as harder to compare, not automatically as gentler.

Factors to Consider When Choosing Teeth Whitening Strips For Sensitive Teeth
Choosing strips for sensitive teeth is less about finding the strongest-sounding kit and more about matching the formula and routine to your tolerance and whitening goal. These broader checks can help you avoid buying a long treatment course before you know how your teeth respond.
Match the formula approach to your sensitivity
Start by checking the active ingredients rather than relying on words like “gentle” or “sensitive” on the front of the package. Peroxide-free products avoid peroxide, but that alone does not guarantee that every ingredient or wear routine will suit you. Traditional whitening formulas may be more directly aimed at lifting stains, yet can be uncomfortable for some people with sensitive teeth. If sensitivity is frequent or severe, ask a dentist before starting instead of treating a product label as medical guidance. Stop use if pain or irritation develops, and follow the package directions rather than extending wear time.
Separate stain removal from temporary color correction
Purple strips use color contrast to make teeth look less yellow; that is a different mechanism and expectation from a conventional stain-focused whitening treatment. A color-correcting effect may be appealing for a short-term appearance boost, but shoppers should not assume it will produce the same lasting change as a whitening course. Choose purple strips when the temporary visual effect is the goal, not as a substitute for a product designed to address stains. Also check how often the product is intended to be used and whether the instructions describe a temporary effect. Confusing these categories can lead to disappointment even when the strips work as described.
Choose a trial length you can comfortably complete
A short kit can make sense if you are unsure how your teeth will respond, while a longer treatment supply can be more convenient once you know a routine suits you. A higher treatment count is not automatically better for sensitive teeth: it may encourage a longer course than you need or can comfortably tolerate. Compare the number of treatments with the brand’s stated schedule, not just the count printed on the box. Avoid using strips more often or for longer than directed in pursuit of faster results. If you pause because of discomfort, a large pack may be less useful than a smaller, lower-commitment option.
Prioritize fit and wearability, not just the formula
Strips that slip, fold, or do not cover the teeth evenly can make a routine frustrating and may leave some areas untreated. Before buying, check which teeth the strips cover, the recommended wear time, and any instructions about eating, drinking, or rinsing during use. A light or other accessory can add steps without changing whether the formula is a good match for your sensitivity. Pick a format you can use consistently and comfortably rather than paying attention only to extra kit components. If a strip’s shape or application feels awkward, a simpler option may be the better fit.
Know when to ask a dentist before whitening
Existing sensitivity can come from several causes, including dental issues that strips will not address. If discomfort is new, pronounced, localized to one tooth, or present even when you are not whitening, get dental advice before starting a kit. Whitening strips are intended for cosmetic use and should not replace care for cavities, gum problems, or damaged enamel. A dentist can help you decide whether whitening is appropriate and suggest a safer plan for your situation. This check is particularly useful if you have dental restorations, since natural teeth and restoration materials may not respond alike.
Frequently Asked Questions
Should I pick peroxide-free strips or a kit labeled for sensitive teeth?
Those labels describe different things: peroxide-free identifies a formula approach, while sensitive-teeth wording describes the product’s intended audience. Lumineux offers the peroxide-free route in this lineup, and Crest Sensitive White is the clearest dedicated sensitive-kit option. Neither label can promise that you will have no discomfort, since individual tolerance varies. Read the active-ingredient list and directions, then choose based on what you want to avoid and how your teeth usually respond. If sensitivity is persistent, check with a dentist before whitening.
Are purple whitening strips a good choice if I want lasting stain removal?
Purple strips are generally intended to counter yellow tones visually, so they should not be treated as interchangeable with stain-focused whitening strips. Pdoo and the mint purple option in this roundup fit shoppers looking for a color-correcting approach. If your priority is a longer-term change to tooth shade, compare products that are explicitly designed for whitening stains and review their ingredients and directions. Results and duration depend on the product and use, so avoid assuming a temporary color effect will last like a whitening course. Choose the purple format only if its specific purpose matches your goal.
Is it smarter to start with a smaller treatment count if my teeth are sensitive?
A smaller pack can be a sensible way to avoid committing to a long routine before you know how your teeth tolerate it. Lumineux’s 9-treatment pack offers a shorter commitment than its 21-treatment option, and GuruNanda’s 7-day kit is shorter than its 16-day kit. Still, treatment count does not tell you by itself how gentle a formula is or whether it is suitable for you. Follow the product schedule and do not add treatments to make up for a shorter pack. Stop if you experience pain or significant irritation.
Does an LED light make a whitening kit a better choice for sensitive teeth?
An included LED light is an added feature, not proof that a kit will be gentler or a better match for sensitive teeth. The Crest LED kit should be compared with the Crest Sensitive White kit by formula, directions, and your comfort with the extra step, not by the light alone. Check whether the product instructions explain the light’s role and how it fits into the routine. If you want a straightforward choice, avoid letting accessories outweigh the sensitivity-focused details. Follow all directions and stop if treatment causes discomfort.
What should I do if strips cause sharp or lingering tooth pain?
Stop using the strips rather than shortening the wear time and continuing without guidance. Sharp or lingering pain is different from simply finding a routine inconvenient, and a product label cannot identify the cause. Contact a dentist, especially if the pain continues after you stop or is focused in one area. Do not switch immediately to another whitening kit until you understand what triggered the discomfort. When you resume cosmetic whitening, use a schedule and product your dentist considers suitable.
Conclusion
My best overall choice is Crest 3D Whitestrips Sensitive White with 18 treatments for shoppers who want a dedicated sensitive-teeth kit and a longer routine. For best value by routine flexibility, I’d compare the Lumineux 9- and 21-treatment packs: the smaller one limits commitment, while the larger one suits buyers already set on a peroxide-free approach. The best premium-style pick is Crest’s Sensitive & Gentle kit with LED light for shoppers who want an added device, though the LED feature is not a reason by itself to expect greater comfort. For beginners, GuruNanda’s 7-day kit or Lumineux’s 9-treatment pack offers a shorter starting point than the longer-course alternatives. For specific needs, choose Pdoo or the mint purple strips for temporary color correction, and consider InoPro or the generic 28-count strips only after checking their formula and directions carefully. If your sensitivity is ongoing or severe, ask a dentist before using any whitening strips.
