Question by Gina: Why are so many reputable toothpastes not approved by the American Dental Association?
I remember a time when you just didn’t use a toothpaste if it didn’t bear the ADA seal. But now you have to hunt to find it in the toothpaste aisle, and it generally only appears on the plane jane toothpastes. My dentist even gave me a sample recently that wasn’t ADA approved. What’s the deal?

I would assume that it has something to do with costs and time.
