Root Canal Therapy

A root canal is needed when the nerve of a tooth has become damaged by injury or compromised by decay. When the inside pulp, or nerve, of a tooth becomes compromised, it will cause severe pain and sensitivity. In order to eliminate this pain without extracting the tooth fully, we can perform a root canal. This procedure saves the tooth and can help restore it to its natural function.

Who is a Candidate for Root Canals?

The way that we can tell if you need a root canal is with an exam and x-rays. We will ask you about your symptoms as well as any pain or sensitivity you're experiencing. There are a few symptoms that mean you may need a root canal.

  • Severe pain while chewing or biting
  • Pimples on the gums
  • A chipped or cracked tooth
  • Lingering sensitivity to hot or cold, even after the sensation has been removed
  • Swollen or tender gums
  • Deep decay or darkening of the gums

If you experience any of these symptoms, it's important to visit the dentist to see if a root canal is needed. If a root canal is needed it should be done as soon as possible to prevent the infection from getting worse. Root canals will typically need to be crowned after the procedure because they're prone to breaking and cracking.

What Happens During Root Canal Procedures?

The dentist will examine the tooth using x-rays, then administers local anesthetic. After the tooth is numb, the dentist places a small protective sheet called a dental dam over the area to isolate the tooth and keep it clean and free of saliva during the procedure. The dentist will open the crown of the tooth to allow the removal of the pulp from the pulp chamber and root canals and to shape the space for filling.

After space is cleaned and shaped, the tooth is filled with a biocompatible material. The material is placed with an adhesive cement to ensure complete sealing of the root canals. In most cases, a temporary filling is placed to close the opening. The tooth is filled with composite resin and the dental dam is taken out of the mouth. You will need to return to the dentist to have a crown or other restoration placed on the tooth to protect and restore it to full function.
