Endontics (Root Canals)

A root canal is required when a tooth is decaying internally and requires the dentist to drill into the tooth, extract the pulp prior to refilling and capping the tooth to prevent future decay.

Your teeth are made of a hard material called dentine that is covered in a protective enamel. The interior is made of a sensitive tissue called pulp, which provides oxygen and nutrients to the tooth. Once a tooth is fully formed, nutrients for the tooth come from the tissue surrounding the root and the tooth can function without its pulp.

If the pulp becomes diseased or injured, through poor dental hygiene, fractured tooth, teeth grinding or other illness, the pulp is removed to avoid further decay and to save the tooth. During the procedure the dentist will clean and shape the root canals leading from the root of the teeth to the interior pulp. The interior is then cleaned, dried and packed with a filling. A crown or cap is then applied to the top of the tooth to seal the hole and create an artificial biting surface. This process is called a root canal treatment.

Generally, front teeth have only one root, whereas molars can contain up to 4 roots, which may all require cleaning during the procedure.

The symptoms of a damaged or diseased tooth pulp may include:

• Unprovoked or spontaneous pain
• Sensitivity to hot and cold drinks and foods or does not go away
• Pain when biting or chewing
• Pain initiated by temperature changes that then gets worse
• Swelling of the gum near the affected tooth
• Oozing of pus surrounding the affected tooth
• Facial swelling.

Why do I need root canal therapy?

The pain from root canal injury will not heal by itself. If left unattended it will deteriorate, causing worse pain as it progresses. The infection will spread, bone around the tooth will begin to degenerate and the tooth may fall out.

The next alternative is to remove the tooth, which will then require a bridge or implant to maintain your bite. The best solution for you in any case is to keep your original teeth wherever possible. Unless it is unviable, we will recommend a root canal as a first priority.
