What is Root Canal Treatment ?

If your tooth's nerve chamber becomes infected by decay, root canal treatment is often the only way to save your tooth. Inside your tooth's hard outer shell is a nourishing pulp of blood vessels, lymph vessels and nerves. The root canals, which contain the pulp, extend to the bone.

Deep tooth decay, or an injury, can cause serious damage and infection to the pulp's nerves and vessels. Root canal, or endodontic,treatment cleans out the infected pulp chamber and repairs the damage.

Some indications for the need for root canal treatment may be :

•Spontaneous pain or throbbing while biting.

•Sensitivity to hot or cold foods.

•Severe decay or an injury that creates an abscess (infection) in the bone.

Step 1

After the tooth is anaesthetised, an opening is made through to the crown into the pulp chamber

Step 2

The length of the root canals is determined.

Step 3

Unhealthy pulp is removed. canals are cleaned, enlarged and shaped

Step 4

Canals are filled and sealed. A metal post may be added for structural support or to retain restorative materials.

Step 5

The tooth is sealed with a tempory filling. Usually a gold or ceramic crown adds further protection. The material used to fill your root canal will probably last you a lifetime, but eventually the filling or crown may need to be replaced.
