Badly decayed and broken down teeth are saved with Root Canal Therapy, often times in one visit. A small opening in the top of the tooth is made to remove any infection within the tooth. During a root canal procedure, the nerve and pulp is removed and the inside of the tooth is cleaned and sealed.
The pulp or pulp chamber is the soft area within the center of the tooth. The tooth's nerve lies within root canals, which lie within the roots or "legs" of the tooth. The root canals travel from the tip of the tooth's root into the pulp chamber, which also contains blood vessels and connective tissue that nourish the tooth.
Why does the pulp need to be removed?
When nerve tissue or pulp is damaged, it breaks down and bacteria begin to multiply within the pulp chamber. The bacteria and other decayed debris can cause an infection or abscessed tooth. An abscess is a pus-filled pocket that forms at the end of the roots of the tooth. An abscess occurs when the infection spreads all the way past the ends of the roots of the tooth.
Signs that you might need a root canal
Sometimes no symptoms are present; however, signs to look for include:
- Severe toothache pain upon chewing or application of pressure
- Prolonged sensitivity/pain to heat or cold temperatures (after the hot or cold has been removed)
- Discoloration (a darkening) of the tooth
- Swelling and tenderness in the nearby gums
- A persistent or recurring pimple on the gums
