When to Use Whitening Strips for Best Results
Whitening strips work better when you use them at the right moment. Not in a fussy, complicated way - just a few simple timing choices that help the gel do its job and keep sensitivity down. Here's when to reach for them.
Time of day
Evening is a popular choice, and for good reason: you're less likely to eat or drink straight after, which gives freshly treated teeth a quiet window. That said, the best time is the one you'll actually stick to consistently. A reliable morning routine beats an ambitious evening one you keep skipping.
Before or after brushing?
Apply strips to clean, dry teeth - but you don't need to brush immediately before. Vigorous brushing right beforehand can leave gums a little raw, so a gentle brush earlier, or simply clean teeth, is ideal. If you do brush just before, give it a few minutes first. Check the specific product's guidance, since some prefer you don't brush immediately prior.

After, not during. Don't eat or drink (other than water) while strips are on.
Give it a buffer. Right after a session, teeth can be more stain-prone - hold off on coffee, tea and wine for a while.
Use the quiet hours. Treating when you won't immediately reach for a staining drink protects your progress.
Planning around an event
Peroxide strips build gradually, so if you've got a wedding or shoot coming up, start a week or two ahead rather than the night before - see how long strips take to work. If you've left it late, purple is your friend: our Purple Whitening Strips give a same-day brightening lift by neutralising yellow tones - ideal for a last-minute polish.
Frequently asked questions
Is it bad to use strips in the morning?
Not at all - just avoid staining food and drink for a while afterwards. Consistency matters more than the hour.
Should I brush right before applying?
Clean teeth help, but harsh brushing immediately before can irritate gums. A gentle clean, or a short gap after brushing, is best - and follow your product's instructions.
Can I drink water with strips on?
Water is fine; other drinks aren't.
