A real brand for a no-brand category.

CRISP started with a gross little moment. Our founder was a year into clear aligners — loving how invisible they were — until taking a tray out at dinner one night and realizing it had a film on it and a smell.

Brushing them with toothpaste (like a dentist's office had suggested) had quietly turned the "invisible" trays cloudy. The fixes were worse than the problem: denture tablets clouded the plastic even more, vinegar tasted disgusting, and the cleaning tablets everyone recommends on Amazon turned out to be persulfate-based — a known allergen that left a chemical taste sitting on the tray all day.

Here's what was strange: millions of people wear an aligner, retainer, or night guard in their mouth for most of their waking (and sleeping) hours, and nobody had built a real brand for the simple job of keeping it clean. Just faceless listings competing on Amazon keywords.

So we built CRISP. One job, done properly: a persulfate-free, aligner-safe three-minute effervescent tablet made specifically for thin clear plastic — no allergen, no aftertaste, no clouding. Drop it in warm water, add your tray, let it fizz, rinse, and wear.

We're honest about what it is: it cleans your appliance — it's not a teeth whitener, and it's not a miracle. What it does, it does cleanly: lifts the film, kills the smell, keeps clear trays clear. And we back it with 60 days, fresh-or-free, keep-the-tablets.

Drop. Fizz. Fresh.
