A root canal is done if you have an infection that affects the pulp of a tooth.

Symptoms[edit | edit source]

Generally, there is pain and swelling in the area. The infection can be the result of a tooth crack, cavity, or injury. It may also be the result of a deep pocket in the gum area around a tooth.

Without treatment, the tooth may become so damaged that it must be removed.

Saving the teeth[edit | edit source]

  • A root canal can save your tooth.
  • Without treatment, the tooth may become so damaged that it must be removed.

Steps in root canal treatment[edit | edit source]

The first symptom you may experience might be teeth pain or dental pain. You call a dentist, who after examining, may refer you to an endodontist. X-rays will be taken and a treatment plan is formed.

Dental Pulp[edit | edit source]

  • Pulp is made up of nerves, blood vessels, and connective tissue.
  • It is found inside the tooth and runs in tooth canals all the way to the jaw bone.
  • Pulp supplies blood to a tooth and allows you to feel sensations such as temperature.

Files[edit | edit source]

  • The infected pulp is removed with special tools called files.
  • The canals are cleaned and irrigated with disinfecting solution.
  • Antibiotics may be placed into the area to make sure all the germs are removed and to prevent further infection.

Fillers[edit | edit source]

Once the tooth is cleaned, canals are filled with a permanent material.

Sealing the teeth[edit | edit source]

The top side of the tooth may be sealed with a soft, temporary material.

Placing a crown[edit | edit source]

Once the tooth is filled with a permanent material, a final crown may be placed on top.


Permanent restoration[edit | edit source]

  • Root canal must be followed by a permanent restoration.
  • This is done in order to restore the tooth to its original shape and strength so it can withstand the force of chewing.

Risks[edit | edit source]

Possible risks of the root canal procedure are:

  • Infection in your tooth root (abscess)
  • Loss of tooth
  • Nerve damage
  • Tooth fracture
