The first thing to understand is that a root canal treatment itself is not the actual source of the pain experienced by most patients. Root canals are intended to relieve pain, not cause it. In fact, with today's anesthesia and surgical techniques, the discomfort experienced during a root canal is no different than having a tooth filled.
Tooth pain is usually caused by damaged, infected tissue, such as the pulp. Root canal treatments remove the troublesome tissue and clean the area. This will stop the infection and relieve the pain. Although the tooth and surrounding area might be sore for a few days, your dentist can prescribe medication to help alleviate the symptoms and allow you to get back to work almost immediately.
Visiting your dentist every six months for an exam, x-rays, and cleaning will greatly help reduce the risk of a root canal. Regular dental exams can catch minor problems occurring in your mouth before they turn into something much worse. Check-ups can also make sure the dental treatment you have previously completed is in good condition. Professional cleanings and exams are vital when it comes to your overall oral health.
