Your description of the problem is quite Limited and insufficient to provide a rational suggestion. A clinical examination and a detailed history will be the best tools to arrive at a proper diagnosis of your problem. The right treatment can be suggested only after the right diagnosis has been made. You should plan a visit to the dentist as soon as possible for a proper clinical examination. There could be multiple reasons for your discomfort and none can be commented upon on an online platform without other informations. Regards.
