Tooth pain almost always comes from an infected tooth where the nerve of the tooth has been exposed and the bacteria has travelled down into the jaw. The only definitive solution is to either extract the tooth or clean out the infection and “reseal” the tooth. The best solution for quick relieve is to contact a doctor and get antibiotics which will treat the infection without resolving the exposed nerve. It will provide temporary pain relief until the real source of the infection can be properly dealt with.
