What is Root Canal Treatment?
Root canal treatment (also referred to as root canal therapy or endodontic therapy) is made necessary when a cavity is allowed, through neglect, to reach all the way to this pulp. (Regular cleanings and checkups prevent and detect problems early).
Sometimes deep restorations or trauma to a tooth may cause the nerve to be damaged to the point it needs root canal therapy, also.
Why you need Root Canal Treatment?
Once the nerve is infected, the infection from the pulp can even extend through the root tip and begin to eat away at the surrounding bone (this is an abscess). By the time the pulp is infected it must be treated, and cannot heal on its own. It can even weaken the entire immune system. This is dangerous, not to mention very painful.
Symptoms for Infected tooth
Symptoms that the pulp has become infected may include sensitivity to hot/cold or sweets, pain, swelling, pain to biting or pressure, and a bad taste in the mouth.
Sometimes, however, no symptoms are apparent and the person is unaware of any problem until a checkup.
How Root canal Treatment is done?
A root canal is performed by drilling a hole in the tooth to access the nerve. The infected tooth pulp is removed with files and canals are disinfected. Once the infection is resolved, the canal(s) are filled in to prevent any further infection. The filling material - Gutta Percha is used to fill the clean canals to finish the root canal treatment. Usually a core build-up and crown is recommended for restoring a tooth to normal size, shape and function that has had root canal therapy.
The only other treatment to root canal filling would be to extract the tooth.
