Why we rate the MySweetSmile whitening strips:
These are our top peroxide-free strip pick for a few reasons. The PAP-based formula is the same gentler, peroxide-free approach used across the MySweetSmile range, which makes the strips a popular choice for sensitive teeth.
They're simple to use 30 minutes and peel off. They're a premium choice rather than the cheapest option, but they come from a brand with a strong, current review record: a live 4.5/5 "Excellent" Trustpilot rating across 8,000+ reviews and over a million customers.
How you use them:
Tear open a sachet to reveal two strips. Place the smaller strip on your bottom teeth and the larger on your top teeth, leave for 30 minutes, then peel off and rinse.
You can run a 7-day cycle for an initial course, then use the remaining treatments for further cycles or as needed, around once a week works well for maintenance. For best results, avoid eating or drinking while the strips are on, and avoid staining food and drink for an hour afterwards.
Honest pros and cons
Pros: peroxide-free; simple 30-minute application; free cheek retractor; from a strongly and currently reviewed brand.
Cons: they're a premium-priced strip, there are cheaper peroxide and PAP options if budget is your priority; strips suit some people better than trays or powder, and fit can feel fiddly at first; results and comfort vary person to person. For composite bonding, MySweetSmile recommends checking with your dentist first.
Who it's for
A good fit if you want straightforward, all-over strip whitening, prefer a peroxide-free option, and are happy to pay a premium for a well-reviewed brand, particularly if peroxide strips have felt uncomfortable before. Less suited to anyone on a tight budget (cheaper strips are available) or who dislikes the feel of strips. Suitable for ages 18+.

How to choose whitening strips
When choosing whitening strips, it's worth weighing up a few things beyond price: whether the formula is peroxide or peroxide-free (peroxide-free options like PAP tend to suit sensitive teeth better), how many treatments you get per pack, and how long each strip needs to stay on. The right choice depends on your teeth and your routine as much as the brand.
The verdict
For a peroxide-free strip from a well-reviewed UK brand, the MySweetSmile whitening strips are our top strip pick — simple to use and a sensible choice if sensitivity has put you off strips before. They're a premium option, so if budget is your main concern it's worth comparing the lower-cost strips in our full comparison first.
