When a tooth is damaged by a cavity or injury that leads to a crack, there is a risk that the pulp inside the tooth may become infected. If this happens, you will need root canal therapy in Toronto to avoid losing your natural tooth.
Although artificial teeth are available to replace a tooth lost to decay or damage, it is always preferable to save your natural tooth.
To determine if you need root canal therapy, your dentist will take X-rays of your teeth to examine the damage. If root canal therapy is the best course of action, you will receive an injection of local anesthetic in the nearby tissue. Your dentist will prevent the spread of bacteria by placing a dental dam over the infected tooth. Using an endodontic file, your dentist will drill a hole through the crown of your tooth to reach the pulp. He or she will then remove all the diseased and dead tissue and disinfect the canal. Once clean, your dentist will shape the canal to receive a filling or sealer to restore the tooth. Fillings for this purpose are made from gutta-percha and prevent the infection from returning. Next, your dentist will seal the hole with another filling. If your tooth is severely damaged, you may need a metal or plastic post in the canal to hold the filling in place. Later, you will return to have a dental crown fitted over your tooth.
