ELI5: Why are so few toothpastes ADA approved?

It seems like most reliable tubes of toothpaste I've seen don't have the ADA logo on them. Just wondering why they don't approve more types of toothpaste...

It's basically because of marketing. The manufacturer has to prove that any advertised claims of what the toothpaste can/will do is 100% accurate before the ADA will give the seal of approval. With all the different claims of what the product will do(E.G. reducing cavities, minty fresh mouth, straightening teeth) it has become near impossible for the ADA to give its seal on newer products. Plain varieties of toothpastes that simply advertise as fluoride toothpastes or refrain from making over-the-top claims are more likely to carry the ADA seal.
