Impacted wisdom teeth, Classification, Symptoms and Removal.
Impacted wisdom teeth (or impacted third molars) are wisdom teeth which do not fully erupt into the mouth because of blockage from other teeth (impaction). If the wisdom teeth do not have an open connection to the mouth, pain can develop with the onset of inflammation or infection or damage to the adjacent teeth.
Wisdom teeth likely become impacted because of a mismatch between the size of the teeth and the size of the jaw. Impacted wisdom teeth are classified by their direction of impaction, their depth compared to the biting surface of adjacent teeth and the amount of the tooth's crown that extends through gum tissueor bone. Impacted wisdom teeth can also be classified by the presence or absence of symptoms and disease.
Classification of Impacted wisdom teeth
All teeth are classified as either developing, erupted (into the mouth), embedded (failure to erupt despite lack of blockage from another tooth) orimpacted. An impacted tooth is one that fails to erupt due to blockage from another tooth.
Impacted wisdom teeth are classified by the direction and depth of impaction, the amount of available space for tooth eruption and the amount soft tissue or bone (or both) that covers them. The classification structure helps clinicians estimate the risks for impaction, infections and complications associated with wisdom teeth removal. Wisdom teeth are also classified by the presence (or absence) of symptoms and disease.
Symptoms of Impacted wisdom teeth
Impacted wisdom teeth do not always show symptoms, meaning you could have impacted teeth and not even realize it. If symptoms do arise, it is usually the result of the gum on top of the tooth becoming infected or swollen. Symptoms may include pain, swollen and bleeding gums, swelling around the jaw, bad breath, headache or jaw ache, and an unpleasant taste when eating. Some people experience stiffness of the jaw or swollen lymph nodes in the neck.
Removal of Impacted wisdom teeth
It is important for dental professionals to remove wisdom teeth carefully so that they don't accentuate or start a periodontal problem. While there currently is no single surgical approach for removing third molars that will particularly minimize loss of periodontal attachment, there are many techniques available to remove them carefully while promoting good healing outcomes. Some of these include:
· Scaling, root planing, and plaque control have the potential to reduce the loss of gum attachment after surgery.
· Periodontal surgical techniques may be beneficial in instances where there is evidence of significant pre-existing periodontal attachment loss.
Indications for wisdom teeth removal
- * Impacted third molars
- * Pericoronitis
- * Grossly decayed third molars
Conclusion
Wisdom teeth and their associated problems are commonplace in the practice of dentistry. An oral surgeon who is trained in their assessment and surgical removal typically performs this routine procedure that is just one aspect of an oral surgical practice.
