Hello everyone. I'm sure someone has been through this. 20 weeks, need to see a dentist. There are holes in 4 teeth, they said to treat them, but I've been afraid to go for 4 weeks now. I don't know how they will treat it, with freezing or without? I'm very afraid of the pain. The local gynecologist already gave me two shots because I haven't healed yet.
