Root Canal Treatment

Root canal treatment (also known as endodontics) is required when the tooth’s blood or nerve supply (known as pulp) is infected by decay or injury.

Why is root canal treatment needed?

If infected with the pulp, the infection can spread through the tooth’s root canal system. This can ultimately result in an abscess. If there is no root canal treatment (RCT), the infection will spread and the tooth may need to be removed.

Does it hurt?

No. Local anesthesia is used and an ordinary filling should feel no different.

What does it involve?

The purpose of the treatment is to remove all root canal infection. To prevent further infection, the root is then cleaned and filled. Root canal treatment is a procedure that is skilled and time-consuming. Most treatment courses will involve your dentist’s two or more visits.

The infected pulp will be removed at the first appointment. Any abscesses that may be present at this time may also be drained. The root canal is then ready for filling cleaned and shaped. A temporary filling is inserted, leaving the tooth to settle. The tooth is checked at a later visit and the tooth is permanently filled after all the infection has cleared.

What will my tooth look like after treatment?

In the past, after treatment, a root-filled tooth would often darken. Usually, however, this does not happen with modern techniques. There are several treatments available to restore the natural appearance if there is any discolouration.

What if it happens again?

Treatment of the root canal is generally very successful. However, the treatment can be repeated if the infection returns.

What if I dont have the treatment?

Having the tooth out is the alternative. Once the pulp is destroyed, it can not heal and leaving an infected tooth in the mouth is not recommended. While some people would prefer an extraction, keeping as many natural teeth as possible is usually best.

Will the tooth be safe after treatment?

Yes. It is better, however, to restore the tooth with a crown to give the tooth additional support and strength. Where can this treatment take place?
Root canal treatment is a routine dental procedure that will be pleased to do for you by your dentist.


Root-treated teeth should be treated as any other tooth should be treated. Remember to use a fluoride toothpaste to clean your teeth at least once a day. Cut on sugar snacks and, if possible, keep them for meals only. For regular check-ups, see your dentist.
