Impacted Teeth Removal

Tooth extraction is the removal of a tooth from its socket in the bone. It is removed If a tooth has been damaged by decay or a fracture and cannot be repaired or restored. Some times the teeth are also eextracted if they are impacted inside the bone and are unable to errupt fully to be functional.  Wisdom teeth are most common teeth to be impacted but some times upper canine teeth also are impacted. If these teeth are causing damage to the adjascent teeth or are giving constant problems, then these teeth should be extracted.

 The other reasons for tooth extraction are:

  • If you are provided with extra teeth that blocks other teeth from coming in. Also special orthodontic treatments may need teeth extracted to create room for the teeth that are being moved into place.
  • People receiving radiation or chemotherapy may develop infected teeth as the weakened there immune system increases the risk of infection.
  • Also an organ transplant may need some teeth extracted to avoid the risk of infection after the transplant, when immunosuppressive medications are given.
  • Wisdom teeth, also called third molars, are generally extracted either before or after they come in. They are removed if they are decayed or cause pain. Also they can irritate the gum, causing pain and swelling, which requires the tooth to be removed.

 

Preparation
  • A record of your medical and dental histories is taken
  • An X-ray of the area is done to help plan the best way to remove the tooth.
  • Prescription of antibiotics to be taken before and after surgery is given,Procedure for extraction. There are two types of extractions:
  • A simple extraction which is performed on a tooth that can be seen in the mouth. It can be done under a local anesthetic, with or without anti-anxiety drugs.
  • A surgical extraction involves teeth that cannot be seen easily in the mouth, either because they have broken off at the gum line or because they have not come in yet. Another reason for a surgical extraction is that the tooth to be removed requires a flap be cut in the gum for access to remove bone or a section of the tooth They can be done with local anesthesia or conscious sedation.

 

 

Risks
A common complication called a dry socket occurs when a blood clot doesn’t form in the hole or the blood clot prematurely breaks off or breaks down. In a dry socket, the underlying bone is exposed to air and food. This can be very painful and can cause a bad odor or taste. It is treated with a medicated dressing to stop the pain and encourage the area to heal.
Other potential complications include:
  • Accidental damage to adjacent teeth, such as fracture
  • An incomplete extraction, in which a tooth root remains in the jaw -A fractured jaw caused by the pressure put on the jaw during extraction
  • Sustained numbness in the lower lip and chin, caused by trauma to the inferior alveolar nerve (during removal of the lower wisdom teeth). Complete healing of the nerve may take three to six months. In rare cases, the numbness, although not disfiguring, may be permanent
