Expertwhite FlexFit™ 12%HP Prefilled Teeth Whitening Trays

Strips sit on the surface of your teeth. FlexFit Trays wrap your entire smile line — front to back, edge to edge — so the dentist-grade peroxide formula makes full contact with every tooth for consistent, even results. No adjusting, no repositioning. Just pop in and whiten.

Most whitening trays you find in stores use low-strength formulas that only treat surface stains. FlexFit Trays use 12% Hydrogen Peroxide — the same dentist-grade ingredient professionals rely on — to reach the deeper discoloration that surface whiteners can't touch.

The formula is pH-balanced to match the natural environment of your mouth, so whitening is effective and comfortable. Enamel-safe. Zero sensitivity.

Expertwhite has been formulating professional-strength whitening since 2003. That's over 20 years of getting the formula right — so you don't have to guess.
