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.
The area around the tooth is numbed with a local anesthetic to start the procedure. The dentist will then create a channel into the tooth to access the canal(s) in the middle of the tooth. They will then be able to remove infected tissue and clean the canal. After the infection has been removed, the space if filled with a sealant called gutta percha.
Teeth that have undergone root canal therapy become much more brittle and prone to fractures and breakage if they are not crowned. This is because the tooth no longer has a nerve in it to provide blood and nutrients to maintain its strength. 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. There may be some soreness following the procedure, but that is normal for most dental procedures. Over the counter painkillers are usually enough to relieve any pain afterwards, but your dentist may prescribe medication. 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. If you are experiencing pain consult your dentist today.
