I've been to many dentists in the past. And this one was the worst. He told me to take out all my previously inserted crowns to get rid of the infection under it. I'm glad I took a second and third opinion before spending $5000. He refused to fill up a cavity saying that only an RTC can be done. I got the filling done by another dentist and saved myself from the pain.
For another tooth (yes I have a lot of dental issues), he filled up a cavity and the very next week I told that I need a root canal for that too. I mean, seriously?

I'm glad I quit going there.
