People would generally have most of their permanent teeth fully functional in their jaws when they’re still in elementary school, then there would be four more teeth that begin to emerge by the time they reach 18. These four other teeth are the third and last molars, which are also called wisdom teeth.
Although some people don’t experience any difficulties when these other teeth emerge, others suffer from impacted molars when these teeth fail to grow normally.
Wisdom teeth become impacted when they aren’t given a clear and spacious enough path to grow and push their way out of the gums. This could result in the teeth growing sideways, at an angle, or even trapped entirely below the gum line, which causes different problems for your other teeth and jaws.
Since teeth are clumped tightly together, undue pressure from teeth against adjacent ones could result in damage to the enamel, thereby opening the possibility of tooth decay and tooth loss. The pressure of erupting wisdom teeth in jaws with inadequate space can also result in insufferable pain.
The problem, however, doesn’t stop there. Although most people would only feel pain and discomfort every now and then, severe cases could cause tumors and cysts because of the damage that impacted teeth are causing. You could have wounds under the gums as well as crushed bones that would slowly but surely create even more problems.
What you could do to avoid these problems is have all four wisdom teeth removed if a panoramic x-ray shows they are impacted. After all, people can function with two sets of molars just as well as they can with three.
