I was to a dentist approx. 9 mos. ago with a cracked filling. He drilled it out and replaced it. It is a large filling with 3 surfaces . He said I might need a root canal down the road or could just have it pulled. The pain went away and was fine for 9 mos. I think it now occurred again due to me grinding my teeth at night. I have severe pain and noticed the tooth is loose. Today it suddenly feels much better. In the past 9 mos it was fine and was not loose. To prevent future problems should i 1. Have a root canal done ? 2. Have it pulled and put in a bridge ? 3. let it go some more and see if it is OK ? 4. I will start wearing a brace when sleeping to see if it occurs again ? It is the second molar from the back of the jaw. Does it make sense to have a root canal being that it's loose ... it do you think it might be OK again once I start wearing the brace at night ?
I've been taking Advil; maybe that suddenly helped the inflamed nerve.
Also I've been applying Ambesol.
