Root Canal Treatment, how is it performed?

Root canal treatment is carried out by our dentist over 2 or more appointments. If the work is particularly complex, our dentist may refer you at Shah Dental Clinics to our specialist colleagues, in root canal treatment, known as an endodontist.

Before having root canal treatment, your dentist may take a series of X-rays of the affected tooth. This allows them to build up a clear picture of the root canal and assess the extent of any damage. Root canal treatment is usually carried out under local anesthetic, a painkilling medicine that numbs your infected tooth and the gum around it. In some cases where the tooth has died and is no longer sensitive, it may not be necessary to use a local anesthetic.

Your dentist will place a rubber sheet (dam) around the tooth to ensure it's dry during treatment. The dam also prevents you from swallowing or breathing in any chemicals the dentist uses. Your dentist will open your tooth through the crown, the flat part at the top, to access the soft tissue at the center of the tooth (pulp). They'll then remove any infected pulp that remains. If you have a dental abscess, which is a pus-filled swelling, your dentist will be able to drain it at the same time.

After the pulp has been removed, your dentist will clean and enlarge the root canal. The root canal is usually very narrow, which makes it difficult to fill. Dentist will use a series of small files to enlarge the canals and make them a regular shape so they can be filled. This part of the treatment may take several hours and may need to be carried out over a number of visits. Your front incisor and canine teeth (biting teeth) usually have a single root containing 1 root canal. The premolars and back molar teeth (chewing teeth) have 2 or 3 roots, each containing either 1 or 2 root canals. The more roots a tooth has, the longer the treatment will take to complete. If the treatment needs to be carried out over several sessions, your dentist may put a small amount of medicine in the cleaned canal in between visits to kill any remaining bacteria. The tooth will then be sealed using a temporary filling.
If you have symptoms from the infection, such as a raised temperature or large swelling, you may be given antibiotics to help manage and prevent further infection. Sealing and fixing the tooth.

At your next visit, the temporary filling and medicine within the tooth are removed and the root canal filling will be inserted. This, along with a filling, seals the tooth and prevents reinfection. Root-filled teeth are more likely to break than healthy unrestored teeth, so our dentist at Shah Dental Clinics may suggest placing a crown on the tooth to protect it. In some cases, a root-filled tooth may darken, particularly if it's died as a result of an injury like a knock to the tooth. There are several ways your dentist can treat discoloration, such as whitening the tooth using chemicals.

A crown is a cap that completely covers a real tooth. It might be necessary to use a crown after root canal treatment to prevent the tooth fracturing. Crowns can be made from, metal or porcelain (or both) a ceramic material powdered glass. The dentist will reduce the size of your tooth and use the crown to replace what's removed. A mold of your tooth will be taken to ensure the crown is the right shape and size and fits your tooth accurately. When fitting the crown, cement will be used to glue the crown to the trimmed-down tooth.If there's only a small amount of tooth left after the root canal treatment, a post can be cemented in the root canal and used to help keep the crown in place. 

Root canal treatment is usually successful at saving the tooth and clearing the infection. Around 9 out of 10 root-treated teeth survive for 8 to 10 years. Having a crown fitted to the tooth after root canal treatment is important for improving tooth survival rates. If you keep your teeth clean, your treated tooth should survive for a long time.
The survival of your tooth depends on a number of factors, including how much of the natural tooth remains, how well you keep your teeth clean the biting forces on the tooth. But if an infection does return, the root canal treatment can be repeated. Or if treatment has already been carried out to a high standard and the infection remains, a small operation to remove the root tip (an apicoectomy) may be carried out to treat the infection..
