The honest short version (read this first)
For at-home whitening strips, Crest 3D Whitestrips are the benchmark, the most established and widely recommended option, so the real choice is which level fits your goal and your teeth. They work with a hydrogen-peroxide gel that lifts both surface and deeper stains over a course of treatments. For the best all-round result, Professional White is our top overall pick. If you are new to whitening, on a budget, or have sensitive teeth, start gentle with Noticeably White. Need it done before an event? 1 Hour Express. Want a light included? White Level 30 with LED. Expect some temporary tooth sensitivity, do not use them on crowns or veneers, and see a dentist if you have pain or are unsure.

Our Crest Whitestrips picks, by what you need
Crest 3D Whitestrips Professional White
This is the pick if you want the strongest all-round Crest result without paying for the premium tier. The Level 12 strips deliver a noticeable, dentist-style whitening over a full course, and the 40-strip kit gives you a complete treatment with strips to spare. It is our top overall recommendation for visible, lasting results at home.
- Strong, even whitening over a full course
- 40 strips, a complete treatment plus extras
- Enamel-safe formula used as directed
Crest 3D Whitestrips Noticeably White
If you are new to whitening, watching your budget, or have teeth that get sensitive, this is the sensible place to start. It is a gentler, lower-commitment kit, ten treatments to lift everyday staining without going straight to the strongest level. Many people with sensitive teeth do better easing in with a milder strip like this and spacing treatments out.
- Gentlest, lowest-commitment option here
- Great value to try whitening for the first time
- A sensible starting point for sensitive teeth
Crest 3D Whitestrips 1 Hour Express
Got a wedding, interview or photos coming up? These Level 12 express strips are designed to give a visible boost in a single one-hour session, so they are the pick when you do not have a couple of weeks to spare. They are a fast top-up rather than a replacement for a full course, but for a quick refresh before an event they are exactly the right tool.
- Visible boost from a single one-hour session
- Ideal for events and last-minute touch-ups
- Same Level 12 strength as our top pick
Crest 3D Whitestrips White Level 30 + LED
If you like the idea of a whitening light, this kit pairs a higher Level 30 course with a Crest LED accelerator, the same blue-light concept used in many premium kits, at a far friendlier price. It is a good choice for deeper or more stubborn staining and for anyone who wants the full at-home whitening experience in one box.
- Higher Level 30 strength for stubborn stains
- Includes an LED light accelerator
- The full at-home kit in one box
How teeth whitening strips work
Whitening strips are thin, flexible strips coated with a peroxide gel that sits against your teeth and breaks down stains. The active ingredient, usually hydrogen peroxide, lifts both surface stains from coffee, tea, wine and smoking and some of the deeper discolouration within the enamel. The higher the level, the stronger or longer the treatment, and results build gradually over a course, typically a couple of weeks, except for the express kits, which give a faster single-session boost. Strips whiten natural tooth enamel only; they cannot change the colour of crowns, veneers or fillings.
Why strips beat whitening toothpaste
Whitening toothpastes mostly scrub away surface stains with mild abrasives, which is why their effect is limited. Strips actually use peroxide to whiten the tooth itself, so they deliver a bigger, more visible change.
In-office whitening at a dentist is stronger still, but also far more expensive. For most people, strips are the sweet spot of real results at a sensible price.
Best whitening strips for sensitive teeth
Some tooth sensitivity is the most common side effect of whitening, but you can usually manage it with a gentler approach rather than avoiding strips altogether. If your teeth react, start with a lower-intensity kit like Noticeably White rather than the strongest level, and use these tips:
- ✓ Use a sensitivity toothpaste for a couple of weeks before and during whitening.
- ✓ Space treatments out, every other day instead of daily, and do not exceed the recommended course.
- ✓ Take the strip off a little early if sensitivity builds, you do not have to use the full time.
- ✓ Avoid very hot or cold drinks right after a treatment.
Sensitivity from whitening is temporary and settles after you stop. If it is severe or does not go away, pause and speak to your dentist.
How to get the best results
- ✓ Brush first, but not right before, apply strips to clean, dry teeth, ideally a little while after brushing.
- ✓ Follow the time on the pack, longer is not better and raises sensitivity.
- ✓ Do not eat, drink or smoke while the strips are on, and go easy on staining foods during the course.
- ✓ Finish the full course for even results, then maintain with the occasional touch-up.
Safety & when to see a dentist (do not skip this)
Used as directed, Crest Whitestrips are considered safe for tooth enamel, but a few things are worth knowing. Temporary tooth sensitivity and mild gum irritation are common and settle after you stop. Do not exceed the recommended course, and do not use strips on crowns, veneers, bonding or fillings, they will not whiten and you can end up with uneven colour. Whitening is generally not recommended for under-18s, or during pregnancy or breastfeeding, without professional advice. Most importantly, see a dentist before whitening if you have ongoing tooth pain, bleeding gums, a lot of staining on one tooth, or visible decay, because discolouration can sometimes signal a dental problem that whitening will not fix and may aggravate. A check-up first makes whitening safer and the results better.
Teeth whitening strips FAQ
Which Crest Whitestrips is the best?
For the best all-round results, Professional White (Level 12, 40 strips) is our top pick. If you are a beginner, on a budget, or have sensitive teeth, start with Noticeably White. Choose 1 Hour Express for fast results before an event, or White Level 30 with LED if you want a whitening light and stronger course. The best one simply depends on your goal and how your teeth react.
Do whitening strips actually work?
Yes. Unlike whitening toothpaste, which mostly removes surface stains, strips use a peroxide gel to whiten the tooth itself, so they produce a visible change over a course of treatments. Results vary with the level you choose, how stained your teeth are, and how consistently you use them, and they whiten natural enamel only, not crowns or veneers.
Are whitening strips safe for your teeth?
Used as directed, Crest Whitestrips are considered safe for enamel. The main side effects are temporary tooth sensitivity and mild gum irritation, which settle after you stop. To stay on the safe side, do not exceed the recommended course, avoid using them on dental work, and see a dentist first if you have pain, bleeding gums or decay.
What are the best whitening strips for sensitive teeth?
If your teeth are sensitive, start with a lower-intensity kit like Noticeably White rather than the strongest level, use a sensitivity toothpaste before and during, space treatments out to every other day, and remove the strip a little early if needed. Whitening sensitivity is temporary, but if it is severe or persists, pause and talk to your dentist.
How long do the results last?
Results typically last several months, depending on your diet and habits. Coffee, tea, red wine and smoking will re-stain teeth over time. You can keep your smile bright by going easy on staining foods and doing an occasional touch-up or short maintenance course rather than whitening constantly.
Can I use whitening strips on crowns or veneers?
No. Whitening strips only lighten natural tooth enamel, they will not change the colour of crowns, veneers, bonding or fillings. If you whiten natural teeth that sit next to dental work, the shades may no longer match. If you have visible dental work in your smile, ask your dentist about your options before whitening.
The bottom line
Crest 3D Whitestrips are the most trusted at-home whitening strips, so the decision is really about which level. Professional White is our best overall pick for visible results, Noticeably White is the smart start for beginners, budgets and sensitive teeth, 1 Hour Express is the fast option before an event, and White Level 30 with LED suits anyone who wants a light and a stronger course. Whichever you choose, follow the instructions, expect a little temporary sensitivity, keep them off any dental work, and see a dentist if anything hurts. Done sensibly, strips are the best-value way to a brighter smile at home.
