CRISP Aligner & Retainer Cleaning Tablets
Drop. Fizz. Fresh.
The 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.
Here's the part nobody mentions when you start clear aligners: the tray you wear for 22 hours a day becomes a warm, wet home for bacteria. You rinse it, maybe brush it, and it looks okay — but by dinner it's got a faint film and a smell you really hope nobody notices when you take it out.
So you try to clean it better. Toothpaste? Gritty — it scratches the plastic and now your "invisible" tray looks cloudy. Denture tablets? Too harsh for thin aligner plastic. The popular tablets everyone grabs on Amazon are usually persulfate-based — a known allergen that leaves a chemical aftertaste you then 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 one tablet into warm water, add your aligner, retainer, or night guard, and let it fizz for three minutes. The effervescence lifts the bacteria film, stains, and smell out of every crevice your toothbrush misses — then rinses clean.

Your aligners cost thousands. Clean them like it.
Invisalign and clear-aligner treatment runs into the hundreds or thousands of dollars — and you wear the trays all day. Cleaning them properly costs a few cents a day, protects your treatment, and means you never have to dread taking them out.
