Root canal therapy is performed to treat infection in the centre of a tooth (the root canal system) where the resides. The nerve can become inflamed, potentially die and/or become infected when bacteria infiltrates its This can result from tooth decay, cracks in the tooth, or trauma to the tooth (blunt force, severe temperature changes). A tooth infection can be quite painful and should be treated as soon as symptoms are noticed to spread. However, some infections may not be painful at all and can only be identified as a pimple or swelling gums or are discovered by chance on routine x-rays.

Root canal therapy is a relatively comfortable procedure for the patient as it is performed with local freezing. involves removing all bacteria including the infected nerve from the root canal system. The area is cleaned precision instruments and irrigated to thoroughly disinfect the space. The canal is filled with a rubber-based material and sealed with a temporary filling (replaced with a permanent filling at a follow-up appointment) prevent bacteria from re-entering. The tooth may require a crown to minimize the risk of future fracture. This especially important for teeth located in the back of the mouth where biting forces are strongest, and teeth prone to breaking. It is also helpful to place a crown over a tooth that is mostly made up of filling material, not as strong as natural tooth structure.

After your root canal, you can expect some sensitivity as the freezing wears off. It is important to avoid eating drinking until all numbness has subsided. There may be a small amount of pain or swelling around the treated but this should be relieved by over-the-counter medications such as Tylenol.
