One of the most common extractions is done on wisdom teeth because they often cause problems as they begin to break through the gums. Many times, we see those wisdom teeth are impacted, meaning the tooth is coming in at an angle instead of straight through the gum line. This can cause pain, the tooth can come in unevenly, or the tooth may only emerge partially.
Impacted teeth and wisdom teeth that can potentially cause problems, like infections, need to be removed. Extractions can range from a single tooth to removing all four wisdom teeth at once.
