While initial symptoms are not yet a sign of an extended infection and you can normally wait a few days before you go to the doctor, make sure you do it immediately if you notice swelling on the face, if you have a fever and difficulty breathing and swallowing or when you begin to suffer from insomnia even though you feel tired. All of these symptoms indicate that the infection is already widespread and has do be dealt with promptly.
The doctor will do an X-ray of the sore tooth and will be able to tell how advanced the infection is, what area exactly it affects and what kind of treatment can bring relief. Very often the patient has to undergo a root canal treatment to have the infected pulp and the active nerve removed.
In some cases traction is the only solution, so to avoid losing the tooth, make sure you see the doctor early enough, even if the visit at the dentist causes stress. The sooner you deal with the problem, the less painful the treatment will be. After the root canal treatment or a traction, it is often necessary to take antibiotics in order to prevent the infection from spreading from the affected area onto healthy gums and teeth.
