3 weeks ago while I was drinking a cold glass of milk I felt a sharp pain in one of my front teeth. A few days later I had a regular monthly checkup (because I have braces) and told the dentist of this certain pain and he relieved some pressure on my front teeth. Perhaps the following few days after I just drank cold water and the pain would start to come back though not as severe. It has been 3 weeks or so since I first felt that sharp pain in my tooth though now I barely feel anything when drinking a cold class or milk, water, juice. However I do feel a slight pressure on the questionable tooth. I have since gone to the dentist once more and he said that I have a root canal because apparently the tooth is somewhat darker meaning the nerves inside are inflamed or something. I am not covered by insurance so the price of the surgery would be costly and I am just 20 years old so that's quite a bit of money. I have scheduled for root canal date but I would like to have a 2nd opinion from you guys and will try to see a local Endodontist before then. Any help would be appreciated!
