What is a Root Canal?
A root canal is a treatment to repair and save a badly damaged or infected tooth. The procedure involves removing the damaged area of the tooth (the pulp), cleaning and disinfecting it and then filling and sealing it. The common causes affecting the pulp are a cracked tooth, a deep cavity, repeated dental treatment to the tooth or trauma. The term “root canal” comes from cleaning of the canals inside the tooth’s root.
Pain and Needing a Root Canal Treatment
For some people they question whether or not the really need a root canal when they do not have any pain. However it is important to know that many teeth that need root canal therapy will not cause pain. But that does not mean the tooth is okay.
Your dentist and or endodontist specialist have ways to see if the tooth’s pulp is damaged or infected. If it is, then you will need root canal treatment, even if the tooth does not hurt. Therefore if you see something near a damaged tooth that looks like a pimple, see your dentist. The “pimple,” called a fistula, is a tunnel of tissue draining pus from an infection. There is no pain because the fistula keeps pressure from building in the tissue. It can come and go. The infection must be treated, and the tooth probably needs root canal treatment. Without treatment, nearby tissues will become infected.
Root Canal Treatment is Not Usually Painful.
Often time when people are told they need a root canal they worry about pain and are fearful of having the treatment done. However, the pain they feel is caused by an infection in the tooth, and not by root canal treatment. A root canal is done to eliminate that pain. The root canal procedure itself is painless.
A local anesthetic numbs the tooth and the surrounding area. For those people whom may be afraid to have a root canal because they are anxious about having dental work done. Dentists can provide calming medicines, such as nitrous oxide.
