Root Canal Therapy
Root canal therapy is treatment used to repair and save a tooth that has been infected due to a deep cavity or cracked tooth. The treatment involves removing the pulp and the nerves of the tooth, and cleaning the infected area. A tooth's pulp and nerve is not important to a tooth's health and function after the tooth has fully emerged from the gums. If the treatment is not performed, pus builds up at the root tip and the infection of the pulp can spread to the surrounding bone. The results in pain and swelling, and your tooth would likely have to be removed.
What are the signs that a root canal is needed?
- Severe tooth pain while chewing
- Your tooth pain wakes you up at night
- Teeth that are highly sensitive to hot or cold, with the sensitivity lingering for some time.
- Discoloration or darkening of the tooth
- Swollen gums in the area of the infected tooth
What does the treatment involve?
First, an opening is made into the pump chamber through the crown of the tooth. Once the pulp is removed, the root canal is thoroughly cleaned. If the dentist decides to complete the root canal therapy in multiple visits, a temporary filling will be placed to protect the tooth. When you return, the dentist will remove the temporary filling, re-clean the root canal and pulp chamber, seal the canals with gutta percha. Once a tooth has the nerve removed, it looses its blood supply to the tooth, thus making the tooth brittle and the tooth can crack or break. Within a week or so, as soon as you can, you need to come back in to prepare the tooth for a crown to restore the strength of the tooth.
Root canal therapy has a high rate of success and many teeth undergoing the procedure can be saved to last a lifetime.
