I had a peg tooth located in the top front of my mouth. A few years ago, My dentist bonded the peg to make it fuller. About ten months ago I got a root canal done on this tooth. The back of it was filled in after the procedure. The past week, the tooth has been feeling a little loose. I'm terrified it's going to fall out. What should i do? Is there anything a dentist can do to make sure it doesn't fall out?
