Endodontics is the dental specialty that deals with the nerves of the teeth. Root canals are probably the most notorious procedure in dentistry and the most common procedure relating to endodontics. When a tooth becomes infected it is usually related to the nerves in the root of the tooth. The infected nerves need to be removed. If left untreated an infection can turn into an abscess, which is a much more serious problem that includes bone loss in the jaw.
Symptoms that may suggest needing a root canal are:
- a toothache
- sensitivity to cold or heat that lingers
- a tooth that has darkened
- swelling and/or tenderness of the gums
The area around the tooth is numbed with a local anesthetic to start the procedure. The infected tissue is removed and root canal is cleaned. After the infection has been removed, the space if filled with a sealant called gutta percha. It is highly recommended that a tooth that has undergone a root canal is fitted with a crown. This will improve the appearance of the tooth, and will also make it much more likely that the root canal is successful.
"Root canal" has become a scary term for dental patients to hear, but the benefits of the procedure and advances in dental technology have made it much less "scary". Local anesthetics and proper pain medication allow the procedure to be performed with little to no pain in most cases. The procedure will also relieve you from pain caused by the infection allowing you to enjoy all the foods you love without any pain from heat, cold, or biting too hard.
