Root canal therapy in NYC, also known as endodontic treatment, is a method designed to save and restore teeth that have been harshly damaged or infected. It involves eradicating the infected or inflamed pulp from within the tooth, cleansing and disinfecting the root canal system, and sealing it to control further infection. By addressing the underlying cause of tooth pain and decay, root canal therapy alleviates discomfort and preserves the natural tooth structure.
