My family has ectodermal dysplasia and very severe dental problems because of it. I've always had weak enamel and teeth that just break apart or rot out or get infected no matter what dentists advice I follow or how well. I eventually got so frustrated with painful teeth I started using only peroxide as a mouth wash and baking soda as toothpaste. The first year of my life I didn't have any cavities or problems so the dentist asked what I used. When I told him he immediately advised against it! Hahaha.
