Bye-bye dentists!

Growing up I got my first filling at 18 and I only have three. I drink lots of soda and when I had holes in my teeth I never told my mom. I would just brush my teeth and they would grow back just like any other normal bone in your body does! But that's what Dentist don't want to tell you!
I finally lucked out in the dental world; I have a great dentist now. I have only needed cleanings and concurrent checkups the past few years, but they also check for oral cancer, which I greatly appreciate.
On the other end of the spectrum, I once went to a dentist who "accidentally" brushed against something no other dentist did in my entire life. Never went back.
