What Is a Teeth Whitening Tray Kit
A teeth whitening tray kit usually includes custom or boil-and-bite trays and a whitening gel with peroxide. You fill the trays and wear them for a set time each day, typically 30 to 60 minutes, to whiten tooth surfaces evenly.
How to Choose the Best Kit
Look for ADA-accepted ingredients, clear gel concentration, and a comfortable fit. Kits with boil-and-bite or dentist-provided trays help reduce gum exposure. Avoid kits with overly harsh abrasives or unrealistic claims.
Tips for Safe and Effective Use
Brush and floss before use, apply a pea-sized amount of gel per tray, and follow the recommended wear time. Store the kit in a cool, dry place. If you experience persistent sensitivity, stop use and consult a dental professional.
