In the meantime, he also practiced as an Endodontist in private practices in Manhattan, Brooklyn, and Long Island until 1984. He moved to California and in 1985 he started his Endodontics practice in Long Beach, CA. Since that time, he has been successfully and proudly practicing and serving his patients, who are referred by general dentists from all over the Los Angeles and Orange County areas.

He is a Member of the Harbor Dental Society, a Lifetime member of the California Dental Association, a lifetime member of the American Dental Association, and a lifetime member of American Association of Endodontics.

These dentists and their support staff give compassionate and individualized attention to each patient with detailed evaluation of the patient’s needs and a thorough discussion of findings.

Our Procedures

Root Canal Treatment: Having knowledge about the anatomy of a tooth can help a patient understand what a root canal treatment entails. (first diagram, left). Pulp tissue (which is made up of blood vessels and nerves) is contained in the canals of an otherwise healthy tooth. When pulp tissue becomes inflamed or infected, a root canal treatment becomes necessary (second Diagram). This can happen as a result of a deep cavity, or cracking and chipping of a tooth, causing pain, infection, and swelling. At this point, the pulp tissue and the surrounding infected tissue have to be removed from the canals (Third Diagram). The canals are then carefully cleaned, washed, and dilated using tiny files. Lastly, the root canal is filled with cement and filling materials (fourth Diagram).

Root Canal Retreatment: Rarely, a root canal treatment may fail or the treated tooth may not heal as expected. In that case, the initial root canal treatment has to be redone. Reasons for failure of a root canal are numerous and include: unusual anatomy of a canal, delayed restoration, new decay exposing filling materials to bacteria, or a cracked tooth. The same procedure states above is used to perform a root canal retreatment.

Surgical retreatment “root-end resection”: When a root canal retreatment is not possible, the gum tissue near the end of the infected root of a previously treated tooth is exposed. This allows the dentist to remove the tip of the root and clean out the infected tissue (Diagram, 6&7).

Our Technology

  1. Digital x-ray system.

  2. Electronic devices. Used as apex or root end locators, which are needed for measurement of the roots as well as reduction in radiation exposure.
  3. Nickel Titanium Rotary Files. Used to clean and shape the canals while preserving the natural anatomy of the canal and preserving root structure. This improves prognosis and longevity of the tooth.

  4. High-end, powerful microscopes. Used for select complicated cases, which allows for a higher rate of
    success and better prognosis of the treatment.

  5. CT Scan, 3D imaging machines. Used to see the intricacies and detailed anatomy of the canals and the surrounding tissues in 3D, which improves the success rate of the procedure.
