Root Canal Treatment

A successful root canal treatment is one of the best ways to save a severely damaged tooth, manage dental pain and ensure proper function without having to extract the tooth.

Many people seem to fear this treatment, but root canal treatment is a relatively simple procedure that provides excellent results. It can save even severely infected teeth from being extracted. Depending on how severe the decay is, the treatment may require several appointments.

Why root canal treatment?

Tooth decay, when left untreated, can extend to the nerve inside the tooth. Inside each tooth lie nerve and blood vessels called the ‘pulp.’ If a tooth is decayed or damaged, bacteria can enter the tooth and cause infection in the pulp. Common causes of pulp infection are:

• Deep cavity as a result of ignoring tooth decay

• Cracked tooth that has been left untreated

• Injury to the tooth

If the pulp is infected, it needs to be treated immediately. Else, there can be a build-up of puss at the tip of the root forming an abscess which may destroy the bone around the tooth.

The infected or damaged pulp kill nerves and causes intense pain. The pain typically increases at night and can worsen while consuming cold or sweet foods.

What does a root canal treatment involve?

The procedure for a root canal treatment typically involves the following:

• An opening is made through the crown of the tooth into the pulp chamber

• The pulp is removed, which causes the intense pain

• The infected area is cleaned and sterilised

• The root canals are filled

• Insert of metal or plastic rods into the canal for structural support, if needed

• The crown opening is filled with a temporary material

• Fitting of crown (permanent material) over the tooth to restore the natural appearance and prevent the remaining tooth structure to become brittle or fractured 

After the treatment, you may experience some pain when biting down on the treated tooth. This pain should disappear within about 48 hours. The dentist may prescribe an anti-inflammatory drug to help.

How long does a root canal treated tooth last?

Once the tooth is treated and restored, it can last an entire lifetime, provided you care for it well. Remember that decay can still happen in treated teeth, therefore you need to maintain excellent oral hygiene to prevent further problems.
