Tooth extraction is the removal of a tooth for various reasons. These reasons include severe tooth decay, severe gum disease, dental trauma, crowding of teeth (jaw stenosis) or teething problems. Some teeth may also need to be extracted for orthodontic treatment or dentures. The tooth extraction procedure is usually performed under local anesthesia, which prevents the patient from experiencing pain and discomfort. Before tooth extraction, it is important for the dentist to assess the patient's condition and determine the appropriate treatment plan.
