CRISP Aligner & Retainer Cleaning Tablets
Drop. Fizz. Fresh.
4.8· 8 reviewsThe clear aligner you wear 22 hours a day grows an invisible film. CRISP lifts it in 3 minutes — persulfate-free, aligner-safe, no clouding, no awful smell. Built for clear aligners, not dentures.
There's a bacteria farm in your mouth 22 hours a day.
The tray you wear 22 hours a day becomes a warm, wet home for bacteria. By dinner it has a film — and a smell you hope nobody notices.
Toothpaste scratches the plastic. Denture tablets are too harsh. Most Amazon tablets are persulfate-based — a known allergen that leaves an aftertaste you wear all day.
You're stuck choosing between a tray that's dirty or one that's damaged.
Meet the persulfate-free 3-minute reset.
Drop a tablet in warm water, add your tray, fizz for 3 minutes. Lifts film, stains, and smell from every crevice — then rinses clean.
