My name is Ken. I am 42 years old. I had a dental appointment on 04/06/11 for a deep cleaning. When I arrived the dentist who was supposed to work on me was so busy that another dentist did my cleaning. I have to mention that he didn't introduce himself so that made me nervous. I asked him what procedure he was going to perform just to make sure he wasn't some guy off the street. He said "Deep Cleaning" and I felt a little at ease. Anyway the dentist said he was going to try to perform the deep cleaning with out the numbing medication but it was to painful so he pulled out his needle and began injecting my lower gums. At first he did the left side which went pretty smooth and then he did the right side. When he injected the right side I almost jumped out of the chair because it was so painful. I assumed that he hit a nerve. So he proceeded to clean my teeth and when he was done I was impressed. They looked nice. He told me the pain medication would wear off in a few hours and I would be able to eat. When the medication wore off my right lower jaw/mouth was still very soar. I thought the pain would go away but it never did. Until this day I cannot open my mouth completely wide . It's like my jaw gets stuck and it is painful. Things I use to enjoy like burritos and hamburgers I can't because I cant open my mouth and when I attempt to it is so painful I can't explain it. I called the dentist and they did a follow up and said " Do some mouth stretching exercise and that should help". If the pain continues come back and we will send you out to a specialist. I am very nervous about my condition. It's very scary not being able to eat like I have been eating all my life. Can you give me some insight on this matter? Thank you.
