What is a root canal?
Root canal treatment is designed to eliminate bacteria from the infected root canal, prevent reinfection of the tooth and save the natural tooth. When getting a root canal, the inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and disinfected, then filled and sealed.
Why do I need a root canal?
Inside your tooth, beneath the white enamel and a hard layer called dentin, is a soft tissue called pulp. This tissue contains blood vessels, nerves and connective tissue, which help grow the root of your tooth during its development and provide sensation to your tooth. The pulp can become inflamed or infected by invasion of bacteria or by trauma. If bacteria create a cavity deep enough into your tooth, they will infect the pulp causing severe pain to cold liquids and/or to chewing.
Alternatively, if you have traumatized your tooth the pulp can spontaneously die and decay, causing an infection in the bone around the tooth. Either way, this is not good for your overall health and should be treated by removing the culprit of the infection - the pulp.
What to expect?
Modern root canal treatment is nothing like those old sayings! It’s very similar to a routine filling and can usually be completed in one or two appointments, depending on the condition of your tooth and your personal circumstances. Getting a root canal is relatively painless and extremely effective.
When you have a root canal, the doctor first numbs the area, then makes an opening in the top of your tooth. The pulp is then removed from inside your tooth and the empty canal is prepared for a special filling and dental sealer.
What happens after a root canal?
After the root canal is completed, you’ll have a permanent restoration placed to fill the opening in the top of the tooth. For back teeth it is best to have a crown placed over this tooth to prevent any chance of fractures or reinfection.
