Root Canal therapy is a treatment that removes the nerve from inside the tooth and root. Sometimes when a tooth’s nerve dies, it can get infected. Unfortunately, sometimes the infection shows no signs of discomfort because the body’s immune system is constantly fighting it. This can go on for years before the tooth becomes suddenly abscessed and painful. Other times, the infection and discomfort starts right after the nerve dies. The nerve dying, the infection, and the discomfort can all happen at different times.
Reasons for a Root Canal
- A cavity is so deep that it has reached or is close to the nerve. The nerve could die and get infected.
- A filling is done on a deep cavity that was close to the nerve. The nerve could die and get infected.
- A tooth is traumatized (either physically, thermally, or chemically) and the nerve dies.
- A crown is needed but not enough natural tooth structure remains for the crown to sit on. In this case an elective root canal is done so a retaining post and foundation can be put in place for the crown to sit on.
After a root canal, the tooth becomes very dry and brittle. We usually recommend the placement of a crown to help protect teeth that have undergone root canal therapy. If you think you may need a root canal, we would be more than happy to talk about the options for treatment at your consultation appointment.
