Root Canal Treatment

Have you been experiencing persistent tooth pain along with sensitivity to hot and cold? Do some of your teeth look discoloured? Are your gums swollen and tender?

Our dentists can determine if you require a root canal treatment. Root canal treatment is required when your tooth’s nerve becomes infected This typically occurs due to advanced tooth decay, a severe crack/fracture to your tooth due to blunt force or a deep filling.

How a Root Canal Treatment Works

Root canal treatments typically take place over the course of multiple visits. How long the treatment lasts will depend on how bad the inflammation or infection is. Another factor to consider is the tooth or teeth which are infected – front teeth, for instance, contain only one root canal while back teeth can have up to four root canals – therefore, the more root canals that are involved, the longer the treatment will take.

Once the bacteria are removed, the root canals are filled with dental material to close off the tooth properly so that bacteria cannot re-enter it and cause a new infection.

Finally, the root canal filling is sealed using a crown or permanent filling, so that the tooth can be restored to function normally.

Our dentists will do their very best to ensure your treatment is as pain-free and non-intrusive as possible.

If there is an infection in your tooth’s pulp, it can easily spread to the entire root canal system. This causes an abscess which is an inflamed area where puss accumulates, resulting in severe swelling in tissues surrounding the infected tooth. You may feel a growing pain and your tooth might feel tender while chewing. If a root canal procedure is not administered, this infection will spread to the point that you will need to have the tooth extracted altogether.

A local anaesthetic is always administered prior to treatment – the minor discomfort you might feel is the same as having a normal filling. Post-treatment, you may experience gum swelling or mild pain, in which case, paracetamol or ibuprofen will be prescribed by your dentist.

Immediately following treatment, be careful not to chew “hard food”. Additionally, maintain good oral hygiene by brushing and flossing regularly, at least twice a day.
