Our bodies are incredibly designed and that includes even our teeth! Some teeth last decades without the need for a single filling, while others will become seriously damaged due to trauma or decay. Every tooth has a breaking point where the damage is so extensive that the nerve of the tooth is irreversibly harmed or in some cases dies. The ensuing inflammation has no room for expansion inside the tooth and a toothache results, oftentimes with swelling of your face. A root canal is a procedure that involves removing the damaged nerve tissue and replacing it with a special filling material. This gentle procedure can many times be done in one visit giving you relief from that dreaded toothache.
