Everything You Want To Know Before You Whiten

Yes. Every whitening product we make is peroxide-free and built on PAP, a cosmetic-grade active chosen specifically because it brightens without the free radicals that cause sensitivity. Formulas are enamel-safe and include hydroxyapatite to remineralise as you whiten.

Sensitivity is far less common with PAP than with peroxide, and our formulas add remineralising actives to support enamel during a course. If you do feel any discomfort, skip a day and shorten your wear time — never extend it.

We do not recommend our whitening products during pregnancy or breastfeeding, for under-16s, or if you have untreated decay, gum disease or recent oral surgery. Speak to your dentist first if any of those apply.

No. Gliteeth is cosmetic dental beauty, not dentistry. It does not treat decay, gum disease or structural problems, and it will not change the colour of crowns, veneers or fillings. Keep seeing your dentist.

Most people notice a visible change between day seven and day fourteen. The LED kit typically shows movement sooner because the blue light accelerates the reaction.

Run a full 14-day strip course or 10-day LED course two to three times a year. Between courses, use the pen for touch-ups and the polishing powder two to three times a week.

Use one whitening active at a time. Strips or the LED kit form your course; the pen and powder are for maintenance between courses, not to be layered on top of an active course.

Rinse with water after coffee, tea, red wine or dark sauces. Brush for a full two minutes each evening and spit rather than rinse. Polish a few times a week and top up with the pen every fortnight.
