Root Canal Treatment

The dental procedure used to treat infection at the centre of a tooth.

There is a fine channel inside your tooth called the root canal. A single tooth can have multiple root canals. This area is made up of dental pulp, with nerves and blood vessels. When the dental pulp is infected, there will be toothache or abscess. Historically, such problems in the teeth resulted in their extraction. However, modern dentistry has come up with root canal treatment that contains the infection and saves the tooth.

There are various reasons the dental pulp gets infected. Common causes are decay, deep cavities and cracked or chipped teeth. Typical symptoms of infection are tooth pain, sensitivity to certain foods, discolouration of the tooth and swelling or pain in the gums. If you experience any of these symptoms, visit your dentist immediately for a check-up.

Once your dentist examines you and confirms an infection, treatment will commence. Depending on the nature and severity of the infection and your oral conditions, your dentist will require you to visit the dental surgery a few times for the successful completion of treatment. Root canal treatments are most successful and the tooth will normally last for up to 10 years after treatment.
