Did you know, 41,000 root canals are performed each day, according to the American Association of Endodontists.

Root canal therapy (endodontic treatment) is designed to help save a tooth that’s pulp has become infected or injured. Millions of people receive this type of treatment each year to help save teeth, relieve pain and improve oral health.

Beneath the enamel and dentin (outer layers) of the tooth, there is a soft tissue called the pulp. This tissue contains blood vessels, nerves and connective tissue that helps the tooth to grow during development. If a tooth is fully developed, it can survive without the pulp. Instead, your tooth is nourished by the tissues around it, making root canal therapy an effective form of treatment.

Advantages to Root Canal Therapy

  • Saves the natural tooth
  • Natural appearance
  • Normal biting force and sensation
  • Protects other teeth from excessive wear-and-tear and strain
  • Stops the infection from spreading to neighboring teeth

What is the Procedure for Root Canal Treatment?

There are several steps in the process of root canal treatment and it may involve more than one appointment.

  • Local anesthesia is usually given during a root canal treatment so the patient is more comfortable. To isolate the tooth, the dentist will use a dental dam, a thin sheet of latex rubber or plastic, to help keep the tooth dry during the procedure.
  • An opening is then made through the crown (top) of the tooth into the pulp chamber.
  • The pulp or remaining tissue is then removed carefully from both the pulp chamber and root canal(s). Each root canal is then cleaned and shaped so it can be filled.
  • Medication may be placed in the pulp chamber and root canal(s) to help eliminate bacteria.
  • A temporary filling may be placed in the crown opening to prevent saliva from entering the chamber and root canals, or the dentist may immediately begin the next stage of filling the root canal(s) with a permanent filling.
  • If an infection is present and has spread beyond the root(s), the dentist may prescribe antibiotics.
  • During the next stage of treatment, after placement of a latex dental dam, if a temporary filling was previously placed, it is removed. Root canals are usually filled with gutta-percha, a rubber-like material made from various tropical trees.
  • The tooth is then restored with a crown or permanent filling to strengthen and improve appearance.
  • If an endodontist performed the treatment, it may be recommended to see a general dentist for the final restoration.

Does Root Canal Therapy Hurt?

Patients are given anesthesia during root canal therapy, so it should not be any more painful than any other dental procedure. A root canal can cause mild discomfort and soreness following the procedure but should subside after a few days.

How Much Does a Root Canal Cost?

The cost of a root canal varies depending on the complexity of the problem and treatment needed. A molar can be more complex than other teeth, therefore, it may cost more. Most dental insurance policies provide some coverage for endodontic treatment. Be sure to check with your insurance carrier to confirm what is covered in your plan.

Endodontic treatment usually costs less than having a tooth extracted. When a tooth is extracted, it is typically suggested that the tooth be replaced with a bridge or implant. The additional procedures related to extraction can add up to a high cost than a root canal.
