Root canal treatment is a highly successful procedure, with a success rate of over 95% according to the American Association of Endodontists. In most cases, it can last a lifetime, provided that the patient maintains impeccable dental hygiene habits and wears a crown. The vast majority of root canals will last at least 5 years, with many lasting up to 10 or 15 years. However, there is always the possibility that the roots may decay or the entire tooth may crack or move, requiring new endodontic treatment.
According to a report, 98 percent of root canals last one year, 92 percent last five years, and 86 percent last ten years or more. Molars treated by endodontists had a 10-year survival rate significantly higher than those treated by general dentists. When considering whether to remove a root canal, patients should consider alternatives such as dental implants, which can offer a healthy and fully functioning tooth that lasts for many years. Root canal insufficiency can cause pain, tenderness when biting, gum inflammation, loose teeth, or sinus pain.
If you suspect that you may need a root canal, it is best to schedule an appointment with a dental specialist. Root canal therapy is often used as a last resort to save a tooth that has been damaged by decay or an accident. If the remaining roots become infected in the future, they will also need to have a root canal performed. Retreatment can be successful and have a good prognosis; however, it is more difficult when treating the back teeth because the roots can contain several nerve channels that must be accessed.
