Endodontics (from the Greek endo "inside"; and odons "tooth")deals with the tooth pulp and the tissues surrounding the root of a tooth. Endodontists perform a variety of procedures including root canal therapy, endodontic retreatment, surgery, treating cracked teeth, and treating dental trauma. Root canal therapy is one of the most common procedures. If the pulp (containing nerves, arterioles, venules, lymphatic tissue, and fibrous tissue) becomes diseased or injured, endodontic treatment is required to save the tooth.After this is done, the dentist fills each of the root canals and the chamber with an inert material and seals up the opening. This procedure is known as root canal therapy. With the removal of nerves and blood supply from the tooth, it is best that the tooth be fitted with a crown which increases the prognosis of the tooth by six times.
Indication for root canal treatment:
- Significant constant pain (usually pulsing type)
- severe pain that wakes you up at night
- Pain when you lay down
- Pain while chewing
- The appearance of a swelling
There may be a case when a tooth does not pain but may require root canal treatment:
Reason:nerves of a tooth are severly damaged because of which there is lack of any pain and sensation(hot and cold) and such a nerve indicates an infection and root canal treatment to prevent the spread of infection asymptomatically in the surrounding bone and destroying the bone.
