Regenerative endodontics uses biologically-based tissue engineering to restore tooth canals of immature permanent teeth to a healthy state. Regenerative endodontic treatment involves replacing damaged pulp tissue in the tooth root with healthy tissue that can allow for continued development of the tooth root and surrounding tissue. Offering a promising alternative to traditional root canal treatments, which halt further growth of the tooth root, regenerative endodontics opens new avenues for preserving natural tooth structure and function, highlighting our commitment to incorporating the latest advancements in dental care to benefit patient health and recovery.
