Extractions
Although permanent teeth can last a lifetime, there are a number of reasons why tooth extraction may be needed. The most common reasons are gum disease and tooth decay.
​Our mission is to try to save as many teeth as possible. But unfortunately there are some instances when extractions are required.
​
-
A crowded mouth. Sometimes dentists extract teeth to prepare the mouth for orthodontics. The goal of orthodontics is to properly align the teeth, which may not be possible if your teeth are too big for your mouth. Likewise, if a tooth cannot break through the gum (erupt) because there is not room in the mouth for it, your dentist may recommend extraction.
-
Infection. If tooth decay or damage extends to the pulp --the centre of the tooth containing nerves and blood vessels -- bacteria in the mouth can enter the pulp, leading to infection. The tooth itself may also be so badly broken down that it is not structurally possible to restore it.
-
Risk of infection. If your immune system is compromised (for example, if you are receiving chemotherapy or are having an organ transplant) even the risk of infection in a particular tooth may be reason to remove the tooth.
-
Gum disease. If periodontal disease -- an infection of the tissues and bones that surround and support the teeth --have caused loosening of the teeth, it may be necessary to extract the tooth or teeth.
