Thursday I flossed my teeth and Friday my gums were swollen on the left side of my mouth at a tooth I had a cavity filled in at, and it was very painful in just that area. Saturday the pain was gone but my face is a bit swollen right over the tooth and I pushed on it a little and I can feel it in my tooth.  My question to you is what could be the problem and will it go away or do I need to see a dentist asap?

ANSWER:

Based on your description it sounds like the nerve in the tooth may be dying and the tooth may need a root canal to remove the infection. This sometimes happens in teeth with deep decay, but if your face is swollen,  and the tooth is feeling loose you should see someone ASAP. I have friends in the Port Huron as well as the Detroit area if you need me to recommend someone for you to see I can.

Hope this helps,
