Causes of a Root Canal
Root canals are necessary when a cavity that has been left untreated becomes larger. Once the cavity reaches the pulp of the tooth, an infection forms at the base of the root canal, causing an abscess. This abscess is generally painful and will need to be removed.
The doctors at Adam J. Barr DDS know that serious tooth decay can often lead to a root canal. A root canal may be needed if the decay has reached the tooth's nerve. Essentially, a root canal involves cleaning out a tooth's infected root, then filling and sealing the canal.
Root Canal Procedure:
1) An opening is made through the crown of the tooth into the pulp chamber.
2) The pulp is removed, and the root canals are cleaned, enlarged and shaped.
3) The infected area is medicated.
4) The root canals are filled.
5) The crown opening is filled with a temporary.
If you are experiencing severe tooth pain, you may need a root canal. The only sure way to know is to call our Eustis, FL dental office at (352) 357-7900 and setup an appointment with Dr. Barr.
When there is not enough tooth structure remaining after trauma, decay or a root canal procedure, then a post and crown will be utilized to restore the tooth to full form and function. A post is placed in the root canal and then a buildup composed of a bonded composite is used to provide proper support for the new crown. If a crown is placed on an unstable tooth foundation you will have a higher risk of having that crown fail.
