Treatment: When decay is advanced, it can affect the nerve of the tooth, requiring root canal therapy. This consists of removing the nerve tissue and blood supply from the root and sealing the tooth from the blood supply in order to prevent tooth removal. Usually quite successful if tooth decay has not progressed to the point where the tooth cannot be restored.

Root canal: If decay exposes the pulp of the tooth, pain and infection of the pulp(nerve) will result. After decay removal, the pulp needs to be removed to prevent this. Removal of the pulp and a filling in the root space is a root canal. Then the top of the tooth is restored, usually with a crown, sometimes w a filling, depending.

Root canal: If the decay gets into the middle of the tooth, then it needs to be all cleaned out. A root canal means the nerve is taken out of the tooth and cleaned out and filled. This way you can save your tooth.

Infection: Tooth decay is infection of the hard tissues of the tooth. If the infection spreads to the nerve chamber of the tooth, and then to the surrounding bone and gum, the tooth may need root canal treatment. The infected nerve is removed and the root canal is filled. This renders the tooth non-vital but sterile, and it can then be filled or capped and will last many years into the future.

Bacteria from decay close to or into the pulp causes inflammation of the pulp before the pulp itself becomes infected or what we call necrotic!

Root canal therapy: Inside of all of our teeth is a bundle of nerve tissues that sometimes becomes irritated, inflamed, or diseased for various reasons. Once it is determined that your nerve tissue will not heal on its own, the dentist drills a hole in the top of the tooth, removes the nerve tissue, rinses with medicine, seals the chamber, fills it with material, and then fills up the hole.
