Q. I would like to know my risks of going to the dentist. I have a tooth that is broken and decay. It is hurting everyday all day the last week. But I have a huge phobia of dentist due to a problem when I was younger. They gave me something that made me have a allergic reaction and I stopped breathing and all that so I am terrified. I have a few medical probs. I have a heart rate prob. thyroid disease, high blood pressure so i was wondering what are my options? Thnx.,
