Interesting, I knew of someone who also claimed they reversed a cavity by focusing on oral care, and drinking a ton of milk.

Personally, I had a chipped tooth in my early teens and it went away after a decade. I was also drinking about a gallon of milk a day, but I don't know if that's what really fixed my tooth. I wasn't actively doing anything special with my teeth to try to fix them. I just really like milk. The problem just seemed to go away on its own.
