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 with wisdom teeth. In most cases this is because the teeth erupt too close to existing permanent teeth, causing crowding, improper bites, and other problems.
If wisdom teeth are causing a problem, this could mean they are impacted. Impacted wisdom teeth can be extremely painful, as well as harmful to your oral health. Symptoms are easy to spot: pain, inflammation, and some kinds of infections.
Many people need their wisdom teeth extracted to avoid future problems. In general, the lack of wisdom teeth does not hamper one’s ability to properly bite down, speak or eat.
