So I chipped my tooth a couple months ago and I got it bonded with tooth colored resin or something about 2 days later. I also had an xray done 3 months later and they said everything was normal. About 5 months later I noticed bonding was wearing off a little and a couple days later and I had a little sensitivity in my tooth. I also felt a throbbing sensation in my tooth but it is not like an excruciating pain, but I can clearly feel it throbbing. So I had it rebonded and my dentist told me to start using sesodyne tooth paste, but the throbbing still has not gone away 3 days later. What should I do? Is it possible that my tooth is infected? and if it is infected what are my options?
