One of the most common reasons why someone will require a tooth extraction is because they have a tooth that is pushing into another tooth as it grows, also known as impaction. The most frequent cause of impaction is wisdom teeth. Impaction of the teeth leads to necessary extraction because the tooth that is being impacted is susceptible to infection, irritation, and bleeding in the surrounding gums. Other reasons why someone may require a tooth extraction include tooth decay, gum disease, trauma (accidents or injuries that have caused damage to the teeth), and overcrowding. All of these reasons can lead to severe discomfort or pain and potentially progress or cause more issues if the tooth is not properly extracted from the mouth before further damage is done.
