What is an impacted tooth?

                            A 3rd molar wisdom tooth which has failed to erupt in developing growth  in its normal position in the jaw, because (1) less space in the jaw (2) obstruction  in its path by the adjacent tooth. (3) Short & delicate Jaw.

A 3rd molar Impacted teeth may cause problems, such a person as

  • Infection. Pain and swelling at the corner (angle) of the jaw.
  • Pain radiating to the adjacent tooth, neck, ear and head causes Headache.
  • Pain and food lodgment during chewing.
  • Restriction of mouth opening due to infection.
  • Develop Caries or Decay of adjacent teeth.
  • Gum disease.
  • Development of a cyst .
  • Some time develops a tumor is the tissue that formed the crown of the wisdom tooth.

Dr Agravat examine a patient’s mouth , X-rays and history of the complaint  to decide if the teeth are impacted or will not grow in properly.

Types or Classification of  Impacted Wisdom Tooth

There are different types of impacted wisdom teeth, depending on the way the erupt tooth has developed through. In union with the mesial, vertical, horizontal, and distal classifications,

  • Mesio-Angular impaction: The most common type of impacted wisdom teeth. Where the wisdom tooth grows at angled facing, towards the front of the mouth.
  • Disto-Angular impaction: The wisdom tooth angled is back to front. This is the most difficult procedure  to remove impacted tooth.
  • Horizontal Impaction – where the wisdom tooth grows horizontally to the normal occusal plane.
  • Vertical Impaction – The wisdom tooth is straight, but can’t break complete the gums accurately because it’s stuck against the adjacent tooth

Wisdom teeth are also identified as:

  • Soft Tissue Impactions…..

The upper portion of a wisdom tooth crown has penetrated through the Jaw bone, but not sufficient space to allow the gum to be normal positioned and attached to the tooth. This causes problems because it is not possible to keep the wisdom tooth area clean due to food deposition. So frequently Infection , Swelling  and pain occurs.

The Bony Impaction means the wisdom tooth is still wrapped in the jaw bone…..

  • Complete Bony Impaction – There is absolutely no space for the wisdom tooth to grow or erupt. The wisdom tooth is completely encased by bone.
  • Partial Bony Impaction – There is adequate space to allow the wisdom tooth to partially erupt. The tooth remains partially covered by bone and soft tissue. But the chewing process doesn’t work properly. Once again, it is not possible to keep the wisdom tooth area clean due to food deposition. So frequently Infection , Swelling  and pain occurs.

Alone from the 3rd  Molar teeth, other teeth can also get impacted. Most common among these are the upper canine, lower canine and premolars.
