I've done a root canal procedure on that tooth for over 10 years ago, it never bothered me. So I am not sure what I should do about that tooth. But, in your practice, have you ever encountered patients with burning sensation from overfilled material? Can this material cause the burning sensation? Is there a possibility for the burning sensation to go away after the removal of this material? I am going to oral surgeon in a few days for a consultation about the surgery of removing the left material.
