Root canal treatment is the removal of the tooth's pulp, a small, thread-like tissue in the center of the tooth. Once the damaged, diseased or dead pulp is removed, the remaining space is cleaned, shaped and filled. This procedure seals off the root canal. Years ago, teeth with diseased or injured pulps were removed. Today, root canal treatment saves many teeth that would otherwise be lost.
Why and when are root canal treatments required
Decay of the teeth (cavities) if left untreated, generally progress and gradually destroy a significant portion of the tooth before reaching the ‘pulp’ of the tooth. The pulp of the tooth is a thin soft tissue present in the tooth canals consisting of mainly nerves and blood vessels. Once this infection reaches the pulp it gives rise to a common ‘dental pain’. At this stage the tooth can only be saved by performing a root canal treatment.
