Root canal treatment help save the teeth which otherwise needs removal.

The dental pulp is the name given to the soft tissue inside the canal or channel that runs through the root of your tooth. This canal or channel is also known as a pulp chamber. The dental pulp consists mainly of blood vessels, tissue fibres and some nerve fibres. The main function of the dental pulp is to regulate the growth and development of the tooth during childhood. Once the tooth is fully formed nutrition for the tooth comes from the issues surrounding the root. Therefore, a tooth can function without its pulp and, in the majority of cases, can be kept indefinitely. After endodontic treatment the tooth is pulpless, but it is not a dead tooth.

The most common cause of pulp damage is deep tooth decay which allows bacteria to reach into the pulp. The pulp may then become inflamed or infected.Products of infection may then spread through the opening at the tip of the root into the surrounding bone - an abscess could result and this may cause pain and swelling. Not all abscesses cause pain or swelling.

Other causes of pulp damage include: traumatic blows to teeth, loose fillings,excessive wear of teeth, cracked teeth and gum disease. These processes can also lead to infection of the pulp.

Access is gained into the tooth, removing decay and allowing for endodontic treatment to be commenced.

During endodontic treatment, the infected or damaged pulp is removed from the inside (i.e. the root canal) of the tooth via the small access hole.
The root canals are then cleaned, disinfected and shaped to a form that can be completely sealed.
The next stage is to seal (fill) the root canals with a filling material to prevent re-infection.
