When I got there and said I was healthy and I didn't need a mask, they told me I had to wait outside. So I left. And when they called me to say they were ready I went off and called them out for discrimination. Fuck them.
Update: I filed a complaint with their national website, received a call a little while ago about it, and got nowhere with the person on the other end of the line. At least I got another chance to bitch about how stupid it is that I was being discriminated against for being healthy.
Mine told me his last hygienist was onto something about sugar not being the problem, but acidic diets & acids sitting on the teeth.
Basic chemistry it seems. They recommend all patients use a pH balanced or slightly alkaline mouth wash for as long as we are comfortable & at least longer than a minute.
Yes, I reckon mine were damaged when I was young by concentrated fruit juice and later on by cola, and by heavy handed dentists.
I now brush my teeth after eating anything very acidic to remineralise them and they have been stable for years, even the one with a huge cavity.
