Wisdom Teeth Extractions
What Are Wisdom Teeth
Third molars, commonly referred to as wisdom teeth, are usually the last four of the 32 permanent teeth to erupt (surface) in the mouth. Wisdom teeth generally make their appearance between the ages of 17 to 25, and are located at the back of the mouth (top and bottom), near the entrance to the throat. It is thought that wisdom teeth get their name from the idea that the molars surface at a time typically associated with increased maturity or “wisdom”.
In most cases, inadequate space in the mouth does not allow the wisdom teeth to come in properly and become fully functional. When this happens, the tooth can become impacted (stuck) in an undesirable or potentially harmful position. If left untreated, impacted wisdom teeth can contribute to infection, damage to other teeth, and possibly cysts or tumors.
There are several types, or degrees, of impactions based on the actual depth of the teeth within the jaw:
- Soft Tissue Impaction: The upper portion of the tooth (the crown) has penetrated through the bone, but the gingiva (gum) is covering part or all of the tooth’s crown and has not positioned properly around the tooth. Because it is difficult to keep the area clean, food can become trapped below the gum and cause an infection and/or tooth decay, resulting in pain and swelling.
- Partial Bony Impaction: The tooth has partially erupted, but a portion of the crown remains submerged below the gum and surrounding jawbone. Again, because it is difficult to keep the area clean, infection will commonly occur.
- Complete Bony Impaction: The tooth is completely encased by jawbone. This will require more complex removal techniques.
