Deep cavities, repeated dental procedures, cracked teeth, or trauma to the teeth sometimes can result in inflammation or infection in the pulp. Without sufficient treatment, this can lead to pain and abscess. Sometimes a previously treated tooth fails to heal properly or develops new problems. A root canal retreatment by a qualified endodontist often can save your tooth. Lasers can be used to remove the dental pulp and debris. Dr. Onatsky provides the best professional endodontic care, using the most advanced technologies and years of expertise.


Gum disease worsens over time and can lead to heart disease and diabetes.
