Endodontics and root canals

When the nerve tissue inside a tooth degenerates due to deep decay or trauma, a root canal treatment can clear out infection, save your tooth and ensure the tissue around the root stays healthy.

Without treatment, the infection in the tooth pulp can result in an abscess, which can damage the jawbone beneath. If a tooth is causing you pain, has become extra-sensitive to heat and cold, appears discoloured, or the gums around it feel tender and swollen, book an appointment immediately.

4-step procedure

  1. After studying the x-ray of the tooth, Dr. Cheng administers a local anesthetic. He makes an opening in the crown of the tooth and uses it to remove the inflamed nerve tissue, and to clean the root canal to ensure no debris or bacteria gets left behind.
  2. He seals off the cleaned root canal cavity to prevent fluids and bacteria from entering.
  3. He fills the root canal with a gutta-percha and adhesive cement mixture.
  4. He places a crown on the sealed tooth so it can function normally.

After your root canal

You may feel a bit of discomfort for a few days after treatment. Dr. Cheng will recommend an over-the-counter pain medication, or in more extreme cases, he may prescribe an antibiotic and prescription-strength pain reliever to help reduce any remaining infection.

Avoid chewing directly on the repaired tooth until final restoration has occurred, or your tooth may crack. Also, keep in mind that the longer you wait to do the final restoration, the more likely it is that the treated canal will reinfect, requiring another root canal.
