Root canal treatment

Root canal treatment is a dental procedure that replaces a tooth’s damaged or infected pulp with a root filling. The pulp is the tooth’s lifeline – its vessels, tissue fibres and nerves in the central hollow of the tooth keep it alive. The procedure to replace this damaged or infected pulp is also known as endodontic treatment.

Success rates for endodontic treatment are generally high

About 90 to 95 per cent of people who undergo root canal treatment can expect a functional tooth after the treatment. The treated tooth should last a very long time, provided that you maintain good oral hygiene, avoid consuming too much sugar and have regular. Of course, no therapy or replacement will last as well as a healthy tooth.

A tooth is mainly made of a hard material called dentine. Enamel is the surface layer that protects the visible part of the tooth (crown). The part of the tooth that sits beneath the gum line is called the root.

The root helps to anchor the tooth into the jaw. Generally, front teeth have only one root, while molars generally have up to three. Within each root, there can be multiple canal spaces. The pulp is a sensitive tissue that provides oxygen, nutrients and feeling to the tooth.

The pulp extends from the roof of the pulp chamber down into the bottom of each root canal.

If it becomes infected, the entire space needs to be disinfected. Once the tooth is fully formed, nutrition for the tooth comes from the tissues surrounding the root.

Therefore, a tooth can function without its pulp and, in most cases, can be kept indefinitely. A diseased tooth pulp may cause inflammation or infection. The symptoms of a damaged or diseased tooth pulp may include:

• Sometimes
• tooth pulp may become damaged or diseased without any symptoms

In these cases, the problem is usually diagnosed by special tests or during a dental check-up or treatment for other dental concerns. There are many events that can lead to disease or damage to dental pulp. Some of these include:

• Options are available to manage tooth pulp infection
• so it’s important to have this treated when you can to prevent further issues

If tooth pulp infection is left untreated, complications could include:

• once the pulp becomes infected
• it loses its ability to fight the spread of the infection. If bacteria find their way into the pulp chamber
• the bacteria will multiply. This can cause an infection or an endodontic abscess (a pocket or ‘blister’ of pus) when it spreads into the surrounding bone which can become severe

– the infection may spread around the ends of the infected root canal and erode surrounding jaw bone – the tooth may have to be removed, which can affect eating or appearance. Tooth replacement options are available but may be limited if the infection has already caused advanced bone loss. The dentist will listen to your symptoms, examine your teeth and perform other investigations including taking x-rays.

These x-rays also help the dentist to plan for the root canal treatment by showing the number, size, shape and depth of the roots, which shows how complicated the procedure may be. You may need more than one visit to complete the treatment, depending on the difficulty of the procedure. The exact procedure chosen by your dentist may differ from the procedure outlined here.

Ask your dentist for further information

Root canal treatment has four main aims: – to be filled well, the canals within the tooth root need to be shaped into smooth, hollow tunnels that are free of irregularities where residual bacteria may sit. This shaping process involves small instruments, special disinfectants and medication. It may take a few weeks to months for these solutions to take maximum effect against stubborn bacteria within the tooth, and this step may have to be repeated several times – to prevent bacteria from re-infecting the empty canals in your tooth, they are permanently sealed with a long-lasting barrier material – to make sure no bacteria from the mouth can leak back into the tooth, a large, well-sealed restoration is put on the tooth.

Teeth that require root canal treatment have sometimes lost a lot of tooth structure due to previous decay or cracks, and may require further protection in the form of posts, crowns or other similar materials. A normal tooth with a healthy pulp is yellowish-white in colour. A pulp-free tooth that is sealed with a filling rather than covered by a crown may eventually turn grey.

The dentist can advise you on appropriate aesthetic (cosmetic dentistry) procedures to help with this. Who can perform root canal treatments? All dentists are trained to carry out root canal treatments. Some dentists will refer complicated and emergency cases to an endodontist once your tooth has been assessed.

Endodontists are dentists who are specialists in root canal treatment

If you would like a specialist opinion, ask your dentist for a referral to an endodontist. and community dental clinics, for eligible people.
