How successful is root canal treatment ?
Up to 90% of endodontically treated teeth are saved. Of course, getting a proper restoration following root canal treatment, along with good oral hygiene and routine visits to your dentist all influence the prognosis. Unless there are other future complications (fractures, cavities, gum disease, etc.), the tooth can last a lifetime.
As with any dental or medical procedure, there can be no assurance of success. Your endodontist will discuss your options and the chances of success before beginning treatment.
