An extraction means to have a tooth removed, usually because of disease, trauma or crowding.
If you need an extraction, your dentist (oral surgeon) will first numb the area to lessen any discomfort. After the extraction, your dentist will advise you of what post extraction regimen to follow. In most cases a small amount of bleeding is normal. Your mouth will slowly fill in the bone where the tooth root was through the formation of a blood clot.
