About 5 or 6 years ago I feel hard on to my face and my front tooth chipped and I got it bonded and everything was fine for years. About 4 months ago my nephew head budded me and the bonding came out, I got it redone and everything was fine. But today I noticed throbbing on the gum right above the tooth and when I apply pressure to the gum or tooth it hurts. What do I do ? Will it go away over time ?
