Whitening strips are one of the stronger at-home options without a dentist visit: a 2020 systematic review cited by the ADA found limited evidence that whitening toothpastes whiten less than strips, and Mayo Clinic says strips often give better results than whitening toothpaste alone. They hold a peroxide gel against your teeth for an extended period, 30 to 60 minutes per session for the strips on this page. The market is dominated by Crest, but several challengers offer different approaches worth considering. We compared every major whitening strip to find the best option for different budgets, sensitivity levels, and whitening goals. This page ranks strips on whitening strength and cost per treatment. If peroxide has ever made your teeth zing, start with our best whitening strips for sensitive teeth roundup instead, which covers the peroxide-free and nano-hydroxyapatite options in depth. Strips are not the only at-home route: if you would rather buy a complete system, with a gel and tray or an LED unit in the box, our best teeth whitening kits roundup ranks those separately. And if you are still deciding between strips, trays, LED units and whitening toothpaste, our best teeth whitening products guide compares the formats side by side, so start there and come back once you have picked one.
How We Evaluated Whitening Strips
Active ingredient and concentration. Most whitening strips rely primarily on peroxide to bleach teeth, per the ADA, which also notes that strips carrying its Seal have shown safety and effectiveness when used as directed, and that temporary sensitivity and gum inflammation are the most common side effects. We also checked the ADA Seal of Acceptance context when weighing safety claims. Crest’s own guidance says higher peroxide levels tend to work more quickly but may cause more sensitivity. We evaluated the trade-off between speed of results and comfort for each product, and included peroxide-free alternatives for people who can’t tolerate peroxide at any concentration.
Real user feedback at scale. The five picks below carry nearly 215,000 combined Amazon reviews as of this writing (summed from each product’s listed review count). We weighed that review record alongside forum discussions on Reddit and dental communities. The consistent themes in Amazon’s review summaries: Crest buyers praise the results but flag sensitivity and gum soreness, Lumineux buyers praise the comfort but split on the whitening, and Zimba buyers rate its value.
Per-treatment cost. Among these picks, per-treatment cost runs from about $1.42 (Zimba and GuruNanda) to about $2.14 (Lumineux) at prices current as of this writing. We calculated the per-treatment cost for each product because the sticker price is misleading when treatment counts vary from 7 to 22 per box, and when some brands count strips (two strips = one treatment) rather than treatments.
Sensitivity management. Tooth sensitivity is one of the two most common side effects of whitening, per the ADA, and the concern that dominates the forum threads we read. We prioritized products that either minimize sensitivity by design (lower peroxide, added desensitizers) or clearly communicate what to expect so users can manage it.
In the 137 Reddit threads we read across 8 whitening topics, sensitivity fear is the dominant purchase concern, and Crest is the only strip brand with meaningful organic discussion. The budget brands on this page have little authentic community signal, so their entries lean on review data and product-page claims rather than forum testimony.
Evidence Receipt
- Temporary tooth sensitivity and gum inflammation are the most common side effects of whitening, and whitening strips that carry the ADA Seal have shown safety and effectiveness when used as directed, per the ADA’s whitening overview.
- Crest 3D Whitestrips is the only at-home whitening strip line holding the ADA Seal of Acceptance; Glamorous White earned it first in 2017, and the Seal covers specific variants rather than every Crest strip.
- The peroxide does the work regardless of delivery format: in our whitening-kit research a verified dentist dismissed LED add-ons as “a gimmick,” and a 2023 American Journal of Dentistry trial measured significant whitening from a peroxide strip while a peroxide-free plant-oil regimen showed no significant color change.
- Peroxide-free evidence is mixed rather than absent: research Lumineux cites found its non-peroxide strip whitened as much as a Crest peroxide strip with significantly less sensitivity, against a P&G-funded trial that found no significant whitening, so we frame it as gentler, with less certain whitening.
Crest 3D Whitestrips Professional Effects — Editor’s Pick
Crest 3D Whitestrips Professional Effects (22 Treatments)
Best for: Most people: Crest's flagship kit, Amazon's No. 1 best seller in teeth whitening strips as of this writing, with the biggest review base on this page
- 10% hydrogen peroxide per a dental-supply listing; no other strip here publishes a figure
- Advanced Seal technology grips teeth without slipping, so you can talk and drink water during treatment
- 22 treatments per kit (20 plus 2 bonus), with full results over the roughly three-week course
- Amazon's No. 1 best seller in teeth whitening strips as of this writing, with over 105,000 reviews

Why We Recommend It
Crest Professional Effects is the whitening strip the others get measured against. A dental-supply listing gives its formula as 10% hydrogen peroxide (Crest’s Amazon listing gives no percentage, and no other strip here publishes one), and it is Amazon’s No. 1 best seller in teeth whitening strips as of this writing. Both whitening trials we cite on this page used a Crest Whitestrips kit as the peroxide comparison, and Crest’s own claim for this kit is 19 levels whiter in 22 days.
Crest says its Advanced Seal no-slip grip keeps the strips in place for the full 45-minute application, so you can talk and even drink water while whitening. Amazon’s review summary is more mixed: some buyers say the strips stay put, others that they don’t stick properly. Even contact matters, because uneven contact means uneven whitening.
The trade-off is sensitivity: Amazon’s review summary lists painful sensitivity and gum soreness among buyers’ concerns. The ADA says strip sensitivity may develop two to three days into a course and usually resolves by the fourth day after treatment ends. If you know you have sensitive teeth, skip down to Crest Sensitive White, or see our sensitive-teeth strips roundup for peroxide-free and nHAp options.
Who It’s Best For
Professional Effects is the right choice for people who want Crest’s biggest whitening claim among these picks (19 levels in 22 days), who don’t have a history of tooth sensitivity, and who are willing to push through some temporary discomfort for maximum results. It’s the “I want to see a real difference” option.
Potential Downsides
Sensitivity is the primary issue: the ADA notes that transient mild-to-moderate tooth sensitivity can occur in up to two-thirds of users during the early stages of bleaching. The per-treatment cost sits near the top of this list at about $2.09 ($45.99 for 22 treatments as of this writing); only Lumineux costs more per session. And at 45 minutes a day for 22 days, this is not a product for daily maintenance; it’s a course treatment with a defined start and end.

Lumineux Whitening Strips — Best Peroxide-Free
Lumineux Whitening Strips (21 Treatments)
Best for: People who can't tolerate peroxide and want a peroxide-free strip built on plant oils and Dead Sea salt
- 100% peroxide-free formula: whitens using Dead Sea salt, coconut oil, sage oil, and lemon peel oil
- Of about 2,400 Amazon customers who mention sensitivity, roughly 2,100 are positive
- Dentist-formulated: the brand cites peer-reviewed studies for its peroxide-free stain removal
- 21 treatments per box, sold as a three-month supply
- +100% peroxide-free; of about 2,400 Amazon customers who mention sensitivity, roughly 2,100 are positive
- +Dentist-formulated, with brand-cited peer-reviewed studies behind its peroxide-free approach
- +The brand says it gently lifts coffee, tea, and wine stains without damaging enamel
- −Whitening evidence is split: a P&G-funded trial found no significant colour change, a brand-published one found results similar to Crest
- −At about $2.14 per treatment ($44.97 for 21), the priciest per-session pick here
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
Lumineux takes a fundamentally different approach to whitening: no peroxide at all. Instead, the formula uses a combination of dead sea salt, coconut oil, lemon peel extract, and sage oil to remove surface stains. That removes the peroxide the ADA suggests may drive whitening sensitivity, and the comfort record backs it up: in the UC Irvine trial Lumineux publishes, one of 30 users reported mild, passing sensitivity against four dropouts for sensitivity in a Crest peroxide group. For people who’ve tried peroxide-based strips and experienced pain, or who simply want to avoid peroxide entirely, it is NBC Select’s pick for sensitive teeth and the peroxide-free strip we’d start with.
The 4.1-star average (across more than 62,000 reviews) comes with a caveat: Amazon’s review summary calls the whitening results mixed, with some buyers reporting quick results and others saying the strips didn’t work. Expect gentle stain-lifting, which is what the brand promises for coffee, tea, and wine, rather than a guaranteed shade jump; the published evidence, covered under Potential Downsides below, is split on how much it whitens.
Who It’s Best For
Lumineux is the right choice if peroxide causes you sensitivity at any concentration, if you prefer natural ingredients, or if you want gentle maintenance whitening rather than dramatic transformation. It’s also a good option for people who whiten regularly and want a gentler between-session maintenance product.
Potential Downsides
Expect less certainty on whitening than from a peroxide strip, because the published evidence is split. A 2023 American Journal of Dentistry comparison found a plant-oil and Dead Sea salt regimen produced no statistically significant color change while a peroxide strip did, whereas research Lumineux cites found its strip whitened with significantly less sensitivity than peroxide strips. The first trial was funded by Crest’s maker, P&G, and tested Lumineux’s full strip, paste and rinse regimen; the second, run at UC Irvine, found whitening similar to a Crest strip. Read the pair as gentler, with whitening that may or may not match peroxide. Amazon’s review summary backs the mixed picture: whitening results get mixed feedback. At about $2.14 per treatment ($44.97 for 21 treatments as of this writing), it’s also the most expensive per session on this list. For a smaller trial, a 9-treatment pack is available at a lower commitment ($22.99 as of this writing, about $2.55 per treatment: cheaper to try, costlier per session). (Affiliate link)

Zimba Whitening Strips — Best Value
Zimba Whitening Strips (28 Strips / 14 Treatments)
Best for: Adults who want effective peroxide whitening at less than half the price of Crest Professional Effects
- Hydrogen peroxide formula the maker markets as enamel-safe and reduced-sensitivity
- 28 strips per box (two strips = one treatment, a 14-day course) at less than half Crest's total price
- About $1.42 per treatment, among the lowest of any peroxide-based whitening strip here
- Non-slip design; Amazon's review summary says the strips stay in place
- +About $1.42 per treatment (28 strips = 14 treatments), among the lowest costs of any peroxide strip here
- +At about $20, less than half the total price of Crest Professional Effects
- +Marketed as reduced-sensitivity, with the maker promising noticeably whiter teeth after the first use
- −Comfort reviews are mixed: some buyers report sensitivity or pain during use
- −Zimba publishes no peroxide percentage, and Amazon's review summary calls the whitening effect mixed
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
Zimba costs about a third less per treatment than Crest Professional Effects (about $1.42 versus about $2.09). One counting note: the box holds 28 strips, which at two strips per session works out to 14 treatments, a 14-day course. Hydrogen peroxide is the same active ingredient doing the whitening work here as in the Crest kits, though Zimba doesn’t publish its percentage, and the maker markets the strips as reduced-sensitivity. At about $20 for the full course, the value proposition is strong.
The 4.3-star rating across nearly 18,000 reviews is strong for a challenger brand, and Amazon’s review summary says buyers find the strips effective, like the flavor and the value, and see them as cheaper than other options, though the whitening effect is mixed. For people who want peroxide-based whitening without the premium price tag, Zimba hits the sweet spot.
Who It’s Best For
Zimba is the right choice for budget-conscious buyers who want real peroxide whitening, people who plan to do multiple whitening rounds throughout the year, and anyone who finds Crest’s roughly $46 price hard to justify. The 14-day course also makes it a lower-commitment way into peroxide strips than Crest’s three-week kits.
Potential Downsides
Sensitivity still occurs (it’s peroxide-based): Amazon’s review summary says some buyers report no sensitivity while others report sensitivity or pain during use. Zimba publishes no peroxide percentage, and the same summary calls the whitening effect mixed.

Crest 3D Whitestrips Sensitive White: For Whitening Sensitivity
Crest 3D Whitestrips Sensitive White (18 Treatments)
Best for: People who've tried whitening strips before and experienced tooth pain or sensitivity
- Hydrogen peroxide formula Crest says is specially formulated for teeth sensitive to whitening
- No-slip grip, per Crest, so you can talk and drink water while whitening
- 18 treatments for the complete three-week whitening course
- 30 minutes of wear a day, against 45 for Professional Effects
- +Specially formulated for teeth sensitive to whitening, per Crest, and accepted by the ADA, per its listing
- +A no-slip grip Crest says lets you talk and drink water while whitening
- +Still visibly effective: NewMouth's testers found lower sensitivity scores than Crest's Glamorous White, with slower whitening
- −Its listing cautions against use if you already have sensitive teeth or gums
- −Cheaper than Professional Effects, but with 18 treatments versus 22 the per-treatment savings are small
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
If you want Crest-quality whitening but Professional Effects caused you pain, Sensitive White is the logical step down. Crest says it is specially formulated for teeth sensitive to whitening, and the daily wear time drops from 45 minutes to 30; neither kit’s Amazon listing gives a peroxide percentage, so we can’t tell you how much gentler the gel itself is. In NewMouth’s testing it scored lower for sensitivity than Crest’s Glamorous White but whitened more slowly: you trade some whitening speed for comfort.
Who It’s Best For
Sensitive White is the right choice for people who’ve tried Professional Effects and experienced too much sensitivity, and anyone who wants Crest’s ADA-accepted strip line in a formula Crest makes for teeth sensitive to whitening. It is not meant for teeth that hurt before you start: the listing’s caution says not to use it if you have sensitive teeth or gums.
Potential Downsides
Still causes some sensitivity in a subset of users: “sensitive” doesn’t mean “zero sensitivity.” It runs moderately cheaper than Professional Effects ($36.80 versus $45.99 as of this writing), though with 18 treatments per box versus 22, the per-treatment gap narrows to about $2.04 versus $2.09. If even this causes you discomfort, Lumineux (peroxide-free) is the next option, and our sensitive-teeth roundup covers the nHAp alternatives.

GuruNanda Whitening Strips — Best Budget
GuruNanda Whitening Strips (7 Treatments)
Best for: First-time whitening strip users who want to try the category without spending $40+
- Under $10 for a 7-treatment kit (5 professional, 2 express) — the lowest sticker price of any strip on this list
- Dry-strip non-slip formula with coconut extracts
- 7 treatments, each with upper and lower strips — a one-week course
- Low financial risk for testing whether whitening strips work for you before investing in premium options
- +Lowest sticker price on the list: $9.97 for a 7-treatment kit (5 professional, 2 express)
- +Lowest-risk way to test whether whitening strips work for you
- +Delivers visible results, with a 4.4-star rating across nearly 22,000 reviews
- −Its own claim is modest: up to 4 shades whiter, from a one-week kit
- −Its listing gives no peroxide percentage, and some buyers report sensitivity
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
GuruNanda’s kit is the cheapest way into the category at $9.97 as of this writing, though note the box holds a 7-day treatment kit (5 professional treatments plus 2 express), not a multi-week course, so the per-treatment cost of about $1.42 lands close to Zimba’s. The 4.4-star rating across nearly 22,000 reviews backs that up: of about 2,200 Amazon customers who mention effectiveness, roughly 1,900 are positive, even if a one-week kit is not a Professional Effects-level transformation.
The value proposition makes them particularly good as a first whitening strip purchase. Rather than committing $40+ to find out whether you’ll experience sensitivity or like the routine, GuruNanda lets you test the entire concept for about ten dollars.
Who It’s Best For
GuruNanda is the right choice for first-time whitening strip buyers, budget-conscious shoppers, and anyone who wants to maintain mild whitening results between more intensive treatments. The listing labels them for adults, so they are not a pick for teens.
Potential Downsides
GuruNanda’s own claim tops out at 4 shades whiter: don’t expect dramatic shade changes. Its listing gives no peroxide percentage (the two Crest listings here don’t either), which makes it harder to set precise expectations, and Amazon’s review summary says some buyers report sensitivity. For serious whitening, these are a starting point, not an endpoint.

How to Choose the Right Whitening Strips
Maximum whitening, sensitivity tolerable → Crest Professional Effects. The only strip here with a published peroxide figure (10%) and Amazon’s No. 1 best seller in teeth whitening strips.
Least sensitivity, less certain results → Lumineux. Peroxide-free, with a strong comfort record and split evidence on whitening.
Best value for money → Zimba. Effective peroxide whitening at less than half the price of Crest.
Whitening has made your teeth sting before → Crest Sensitive White. If your teeth are sensitive before you whiten, its label says not to use it, so see the sensitive-teeth picks for peroxide-free and nHAp options.
First time trying whitening strips → GuruNanda. Under $10 to test whether the category works for you.
Already tried Crest and it hurt → Lumineux. Peroxide-free, and of about 2,400 Amazon customers who mention sensitivity, roughly 2,100 are positive.
Whitening Strips vs. Other Whitening Methods
Whitening strips occupy the middle ground between mild daily whitening (toothpaste, mouthwash) and intensive professional treatment:
Whitening toothpaste removes surface stains with abrasives, per the ADA. Results are mild but cumulative. Best for daily maintenance.
Whitening mouthwash provides light whitening with each rinse. Results are subtle. Best as a complement to other methods.
Whitening strips (this page) deliver concentrated peroxide contact for 30 to 60 minutes per session. Results are visible within days. Best for noticeable shade change at home.
Whitening pens offer quick touch-ups with peroxide gel. Results are moderate. Best for spot treatment and on-the-go use.
Whitening gels used with trays cover every tooth the tray reaches. Results depend on gel strength and tray fit. Best for maximum at-home control.
Whitening kits (LED light + gel) claim accelerated results. Results vary. Best if you want a comprehensive at-home system.
All whitening formats compared covers trays, LED devices, overnight serums and toothpastes side by side. Best if you have not settled on a format yet.
FAQ
Should I get whitening strips or a whitening kit?
Strips are the simpler and usually cheaper route, and every pick on this page is a peel-and-stick strip with nothing to mold, dose, or charge. A kit adds a tray or an LED unit plus a full course in one box, which buys better coverage on back teeth and, with prefilled professional trays, a higher peroxide concentration than any strip here publishes. If that is the trade you want, our at-home whitening kit rankings cover the tray and LED systems in detail.
How long do whitening strip results last?
No whitening is permanent: Mayo Clinic notes that food, drink, and aging darken teeth again over time. How long strip results last varies with diet and habits; coffee, tea, red wine, and smoking all stain teeth, per the ADA. Plan on a maintenance round when stains return. Between treatments, a whitening toothpaste or whitening mouthwash can help extend results.
Are whitening strips safe for enamel?
When used as directed, hydrogen peroxide whitening strips are considered safe for enamel. Crest 3D Whitestrips is the only at-home whitening strip line to hold the ADA Seal of Acceptance; Glamorous White earned it first in 2017, and the Seal applies to specific accepted variants rather than every Crest strip. Overuse (more frequent than directed, or using multiple products simultaneously) raises the risk of side effects, and the ADA notes some research suggesting bleaching may alter the surface roughness of enamel. Follow the recommended treatment schedule and don’t stack whitening products.
Can I use whitening strips with braces or Invisalign?
Do not use whitening strips with traditional braces: the strips can’t make even contact with tooth surfaces around brackets, and you’ll get uneven whitening. With Invisalign, you can use strips during periods when aligners are out, but consult your orthodontist first. Many orthodontists recommend waiting until treatment is complete.
How often should I use whitening strips?
Follow the product-specific instructions: typically once daily, with course lengths on this list running from 7 days (GuruNanda) to about three weeks (the Crest kits). Don’t exceed the recommended frequency: the ADA lists contact time among the factors behind whitening sensitivity. The labels here set the course length rather than a fixed gap between courses, so repeat a course when stains return.
Do whitening strips work on crowns, veneers, or fillings?
No. Peroxide only whitens natural tooth enamel. Crowns, veneers, bonding, and fillings will not change color, which can create a mismatched appearance if you whiten the surrounding natural teeth. Consult your dentist if you have visible dental work and want to whiten.
