Been there with the teeth, my sympathy.  That can be more than miserable. 

Dentist doesn't bother me now, I can leave my teeth with him and have him call me when he's done.

My advice, and I know the dentist is expensive, but get rid of it.  It's only going to get worse.

Doric.

(Hope it doesn't bother you too much.)

The "I" in Doric is Silent.
