Oh hell yes.

Every tooth has been filled at least once. I have maybe 6 crowns and have had 1 root canal. I have NO enamel on the insides of my upper teeth. It's amazing that I don't have horrible sensitivity.

After 35 years, I'm ashamed to say I still purge though. I want to stop. I just can't. I rinse with baking soda and see my dentist 4x/year and wait for the other shoe to drop.
