On tuesday, I was getting a routine teeth cleaning (fun, fun, fun) and the hygenist noticed I had a cavity, so she was diging around in the cavity and I noticted it gave me more pain than a regular cavity. She finished her buissness, and when I was done, they told me I had an opening later that day to fill the cavity. I go back later that day and that dentist pokes back the cavity for a while, he said that's a deep one with an exposed nerve (he aid I was one before gettiong a root canal). He puts some medicine in it and drills away (which was very painful, by the way) I leave the office still numb, and when the Novicane wears off, It feels like someone it constatnt pushing on the nerve (which the filing is). The pain was so bad it got wore when I sat or lyed down. I called the dentisted he preciped Tylenol 3 (Tylenol with Codeine). Of course Tylenol 3 worked, but I only needed it for a day. I'm still have some residual pain in my tooth and gums, (it not as bad, and dentist said it would come) does anyone know how long that generaly lasts for?
