There is a pain in not any of my teeth but just one in particular. I just got checked a week ago & i was told my teeth are fine. No cavities. & i just got a palate expander about 5-6 days ago. I know it causes pain but no other teeth hurt but that one. It also kind of stung when i used toothpaste & mouthwash . Is there anything wrong with just that tooth?
Dear friend. Thanks for sharing your concern. The reason being that either your palate expander is causing impingement on that particular tooth or there could be gingival (GUM) recession and root exposure on that particular tooth. Do you have this problem in your anterior(front) teeth or posteriors(back tooth)? As the canines and premolars, have long roots and sometimes gets exposed due to gingival gum) recession.  I would suggest you for a revisit to your dentist and get it examined for any tissue impingement or recession of gums. Further it can be managed hope this helps.thanks.
