Root canal treatment

When a large cavity in a tooth reaches the nerve chamber, or in some cases when a tooth breaks, root canal treatment may be required. In order to save the tooth the Guildford Dental Centre team take great care to painlessly clean and fill infected tooth canals with the most up to date rotary systems, before adding a filling material to seal them.

Within every tooth is a nerve chamber and a blood supply in the root canal. In a healthy tooth, these nerves will be alive. Front teeth will normally have one root holding them in the jaw bone, but back teeth can have two, three or four.

If a large cavity in a tooth reaches the nerve chamber, or if a tooth breaks, bacteria can cause the nerves to die. The root canals can become infected and an abscess may form beneath the root(s) of the tooth, in the jawbone. Pain may occur at any time during this process, and the infection can spread.

Treatment is usually carried out over one or two visits to Guildford Dental Centre. The purpose of the treatment is to remove the bacteria or dying tissue from inside the tooth and to clean and disinfect the root canals. This is achieved by making a small hole through the tooth into the nerve chamber, locating and measuring the root canals, then cleaning and widening them using fine instruments. Local anaesthetic is used throughout the procedure to avoid any discomfort.

To aid the instrumentation of these intricate channels to the tooth, magnification may be used and if possible, the tooth will usually be isolated to keep the area dry and clear.

Once clean, the canals are filled to seal them off from re-infection. In most cases, infections will start to heal at this point.

Most patients only experience mild discomfort following treatment, but it is common to experience none at all.

Pleasant people who try hard to make it easy for anxious patients like me have to deal with dental surgery. The receptionist Jackie is so professional and friendly. Reman the periodontist was excellent in describing the treatment, and Clare reassuring in her manner. The surgery is always very clean and it’s a good location.

My experience has always been that the service provided is of the most professional service that one could expect to receive from a dental service.

18th September 2025

Great staff and as a patient who is nervous about dental treatments, really put me at ease.

17th September 2025

Receptionist is friendly and helpful.It is useful to see pictures of all the staff and their biogs on the screen in reception.Dentist (who is relatively new to me, as my regular dentist has been away on sick leave for a long time) is friendly, appears highly competent and explains clearly what she has found during check-up and what needs to be done. This gives me a lot of confidence in her, which for me is essential, as I get very nervous about treatments I might need, such as fillings.
