Going by the description that you have mentioned it seems that your tooth is affected by Irreversible pulpitis. A proper clinical examination by a dentist will be required. An x-ray might also be needed to determine the current condition of the tooth to define the treatment plan. The treatment can vary from root canal treatment to even extraction if the tooth has become non restorable. Medications only provide temporary relief in dental problems so try to avoid depending on the medications to cure this problem. Regards.
