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.

Excellent dentist and hygienist. I receive the best dental care from this practice and have done for some years.

The Hygienist with her Nurse worked hard on the cleaning which they carried in a respectful manner, allowing breaks when I requested.Rachel Akinsanya is informative and clearly explains everything. In addition as I was only thinking this morning, she does not add too many extra steps in one go, to my cleaning regime. It is a case of taking little steps to get there, ie this time she suggested an extra blue interdental brush for cleaning.

My family and I have been coming to Guildford dental for over 20years. I saw Terry and now Derek. Jackie on reception is always very welcoming and takes time to chat when you arrive. Derek is always so professional, kind and always takes the time to discuss options. My children have just been for their check up and my daughter came out and said I really like Derek and trust him with my teeth!

I visited Guildford Dental Centre because of painful wisdom tooth issues and Dr Jonathan Tan was amazing. He was so friendly, calm and reassuring throughout the appointment and explained everything clearly which really helped. The whole team were lovely and the clinic was very welcoming. I would definitely recommend coming here.
