I had an Xray and I was saddened to discover that I have an extra tooth on my upper gum just about the right front tooth. It has been two days now that I've suffered from pain and I couldn't think of something I've done to trigger it. My whole face is swelling. A dentist told me that I need surgery. What kind of surgery do I have to go through? What will happen if the tooth is not extracted? Please help!!! Thanks!
