Signs you Need a Root Canal

Root canal therapy, also known as endodontic treatment, is the procedure used to repair and save a tooth that is badly decayed or infected.  

Inside your tooth, beneath the white enamel and a hard layer called dentin, there is a soft tissue called the pulp. This tissue contains blood vessels, nerves, and connective tissue, which help grow the root of your tooth during its development. When a tooth pulp is damaged, bacteria can cause infection to spread over your gum causing pain.

During a root canal procedure, the dentist will:

  •  Remove bacteria and decay from the tooth pulp, root, and nerve.
  • Disinfect the area with antibiotics.
  • Fill the empty roots.
  • Seal the area to prevent new decay.
