Teeth may require extractions for a variety of reasons. Some of these are:
Severe gum disease
A split tooth which may require removal
Structure loss beyond repair
Problematic wisdom teeth
A wisdom tooth or third molar is the most posterior of the three molars of the human dentition. Wisdom teeth generally erupt between the ages of 17 and 20. Most adults have four wisdom teeth, one in each of the four quadrants of the mouth. It is possible to have fewer, more or none. Extra wisdom teeth are called supernumerary teeth. When wisdom teeth align properly, and there is adequate room for them to erupt, they do not have to be removed. This does not usually happen. They may grow sideways, partially emerge from the gum or even trap beneath the gum, bone and adjacent teeth. The extraction of wisdom teeth is necessary when they can not properly erupt and align with the other teeth.
Should Wisdom Teeth be taken out?
The dentist will evaluate the position of the wisdom teeth with x-ray and oral examination and predicts if there may be present or future problems. Wisdom teeth are generally first evaluated in the mid -teenage years by the dentists and the decision will be made to wait for more development or removal.
Poorly positioned impacted wisdom teeth can become problematic. Bacteria can grow around the partially erupted wisdom teeth and cause infection, resulting in swelling and pain. Other complications associated with wisdom teeth are cysts and tumors formed around wisdom teeth. Early removal is recommended to reduce the risks associated with these complications.
