Although permanent teeth were meant to last a lifetime, there are a number of reasons why tooth extraction may be required. A very common reason involves a tooth that is too badly damaged, from trauma or possible decay, to be repaired. Other reasons include:
Other reasons include:
- 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. If the infection is so severe that antibiotics do not cure it, extraction may be needed to prevent the spread of infection.
- 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 the critical 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.
