Q. Dear Dr. Bohara, I think I have pretty good oral health but I’m considering a nightguard because I occasionally grind my teeth. I was curious how much they cost? I think I sometimes clench my teeth during the day and I have a slight overbite. I think I may have slightly cracked one of my front teeth as a result of this. I’ve looked in the mirror and did not notice any crack whatsoever nor do I feel any pain to pressure or sensitivity to hot or cold but I feel there may be a crack in the back of the tooth. I’m pretty sure of it. If there is a crack, how can the dentist fix it? Would he drill it out and replace it with some resin or composite or place a veneer on it? I don’t think it’s too serious as it’s not causing me any pain but it is annoying and I can sense it with my breath when I exhale. Can you please help me by offering me some suggestions or peace of mind? If the crack is in the center of the tooth can the dentist still treat it? Thank you very much for any response. Sincerely
