What does ‘extraction’ mean in dentistry?


Extraction in dentistry means the removal of a tooth, or multiple teeth from the oral cavity. Depending upon the state and location of the tooth, the procedure can either be simple or surgical. Extractions are performed on local/general anesthesia by professional dental surgeons at offices.

Why are teeth extracted from the mouth?

There are a number of factors that may indicate tooth removal. Some of the most common causes for extraction include:

  • Extensive decay
  • Failed root canal treatments
  • Vertical fractures
  • Supernumerary or extra teeth
  • Retained deciduous/primary teeth
  • Dental impactions
  • Space gaining for Orthodontic treatments to relieve over-crowding
  • Highly mobile teeth due to periodontal diseases

What are third molar extractions?

The third molar, also known as the wisdom tooth is the very last one to erupt in the oral cavity. There are usually four wisdom teeth, one in each quadrant. Because of its late eruption, the tooth does not always have enough space to come out in the right direction, since most of the space in the mouth is already occupied by the other teeth. The third molar/wisdom tooth therefore gets impacted in majority of the people living across the globe. Symptoms of a third molar impaction include pain, swelling, restricted mouth opening and inability to chew properly.

Third molars/wisdom teeth are first observed on dental radiographs to evaluate their positioning in the jaw bone. A decision is made to extract or not and how by the patient and doctor.

Thousands of people have their wisdom teeth extracted and the procedure is entirely safe when performed by qualified professionals at dental clinics/hospitals.
