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, many 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. In addition, it is harder to effectively clean wisdom teeth making them subject to more rapid decay than other teeth.
If wisdom teeth are causing a problem, this could mean that 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 to have their wisdom teeth extracted to avoid future serious problems. In general, the lack of the four wisdom teeth does not hamper one's ability to properly bite, speak, or eat.
