Wisdom Teeth are the third and final set of molars that most people get in their late teens or early twenties. Wisdom teeth that lean toward the second molars make those teeth more vulnerable to decay by entrapping plaque and debris. In addition, wisdom teeth can be entrapped completely within the soft tissue and/or the jawbone or only partially break through or erupt through the gum.
wisdom tooth that is fully erupted through the gum can be extracted as easily as any other tooth. However, a wisdom tooth that is underneath the gums and embedded in the jawbone will require an incision into the gums and then removal of the portion of bone that lies over the tooth. Oftentimes, for a tooth in this situation, the tooth will be extracted in small sections rather than removed in one piece to minimize the amount of bone that needs to be removed to get the tooth out.
The function of the wisdom teeth is also important as a one of moral teeth. But why and when are they needed to be extracted??
1) First , when they are angled toward or away from the second molars or be angled inward or outward. Poor alignment of wisdom teeth can crowd or damage adjacent teeth, the jawbone as below.
2) Second, When a wisdom tooth is underneath the gums and embedded in the jawbone.
