Hello and welcome, First of all let me tell you that please do not ignore getting dental treatments done. If left untreated,it can affect your systemic health too. Get your wisdom teeth extracted. Tooth which is decayed has to be restored/root canal treated. Your tmj has to be examined. Avoid mouth opening too widely. Tmj has to be immobilized for a while. Maintain good oral hygiene. Please do visit your dentist for further procedures. Hope this helps.
