Wisdom teeth are the third and final set of molars that erupt in the back corners of the upper and lower normal adult mouth. Unfortunately, most people experience problems from wisdom teeth; in most cases, this is because the teeth erupt too close to existing permanent teeth, causing crowding, improper bites, and other problems.
Many people need to have their wisdom teeth extracted, sometimes by an oral surgeon, to avoid future serious problems. In general, the lack of the four wisdom teeth does not hamper one's ability to properly bite down, speak or eat.
