Root canal therapy in Chislehurst

Endodontics is the medical term for treatment of the dental pulp, the soft living tissue and cells in the middle of the teeth which nourish and keep them alive. The pulp can become diseased for various reasons and this leads to ‘devitalisation’ of the pulp and the tooth and, in more severe cases, can start destroying the bone that supports the tooth. If left untreated, a diseased tooth will eventually loosen and fall out.

Causes of endodontic disease

The dental pulp becomes infected when bacteria manages to infiltrate the tooth and causes an infection. In a healthy tooth, there is a natural barrier preventing bacteria entering the pulp, but if a tooth becomes unhealthy or compromised in some way, this barrier fails. The most common causes of this are tooth decay due to insufficient oral hygiene, failing restorations, like a defective filling or crown, cracks, damage from a blow to the tooth perhaps in an accident, and gum disease.

Signs and symptoms

Endodontic disease can manifest itself in a number of ways, including sensitivity to both hot and cold liquids and pain when biting or chewing. It can be intermittent pain which occurs when doing any of the above activities, or it can be constant, and both low-level and severe. It can also occur when changing position, like from lying down to standing up or respond to changes in pressure.

If you experience any sort of sensitivity with your tooth, it’s important to come and see us as soon as possible to receive early treatment.

Endodontic disease


If we see signs of disease, the preferred course of action is root canal treatment. This is when one of our experienced dentists carefully removes any infected pulp tissue from the inside of the tooth. After this, they meticulously clean and disinfect the healthy remaining pulp and root to make sure all the infection has been removed. The final step is to fill the root back up with special root-filling material which restores the root to its correct function and protects it from further infection.

If the disease has been left untreated for a while, the effect can be more severe, as the root tip can be infected and an abscess may form. In the most severe cases, the infection then moves into the bone supporting the root and causes bone loss and sometimes a cyst. For these cases an ‘apicectomy’ is performed, where the root tip is removed and any abscess or cyst treated. Where the whole root is lost, your bone will need to be repaired and a replacement tooth secured with an implant.

“Major surgery today, involving putting a post in my root canal to reattach a crown. Completely painless during and after the surgery. My dentist is a genius and I am so grateful for the amazing job they did!”
