Root canal treatment
The treatment that saves teeth damaged deep inside, where the nerve — the dental pulp — is inflamed or infected, so the natural tooth can stay where it is.
Endodontics saves teeth damaged deep inside, where the nerve is inflamed or infected. The best-known endodontic procedure is the root canal, carried out to clear the infection from inside the tooth and to avoid extracting it.
It is indicated when decay is deep, when the tooth aches badly, when there is prolonged sensitivity to hot or cold, or when an abscess has formed. The whole point is to keep the natural tooth in the arch and keep it working.
Done properly, a root canal lets the tooth be kept for the long term, provided it is then protected with a filling or a crown.
