I don’t suppose you remember what the magical ingredients were in those products? Call it morbid curiosity.

You know now that I think about it, I’m not sure how much of dental products are actually FDA approved. I think they might fit into a weird zone where they’re not technically medication or food so FDA doesn’t really look too closely. Dental machinery and appliances for sure need to be FDA-approved, but mouthwash and toothpaste I’m not so sure about. I’m fairly sure the active ingredients within mouthwash and toothpaste, such as fluoride, need to have FDA approval before they can be used, but I don’t think the toothpaste or mouthwash itself needs FDA approval. I think for the most part the FDA oversees marketing claims and manufacturing standards for toothpaste/mouthwash, whereas the American Dental Association (ADA) is the body that “approves” them.

I’m curious. What for? Something non-dental the dentist noticed or something dental-related?

I don’t like those mechanical/timer ones. Especially the ones with a push button top, always felt like I had to smack the button several times just to get twenty seconds of water.
