A dental extraction (also referred to as exodontia) is the removal of a tooth from the mouth. Extractions are performed for a wide variety of reasons. Extractions of impacted or problematic wisdom teeth are routinely performed, as are extractions of some permanent teeth to make space for orthodontic treatment.
When teeth break or are damaged they can be restored with fillings or Crowns by the dentist, but sometimes the Damage is so extensive that the tooth needs to be extracted by the dentist.
there are two different types of extractions ; simple and surgical. Simple extractions are done when the teeth can be removed by the dentist using only forceps and elevators . Surgical extractions are those type of extractions done by the dentist that in order to remove the tooth is necessary to elevate the tissue to expose the bone to get better access, and sometimes is also necessary to remove some bone , in order to gain access to the tooth structure to be able to remove it.
