According to WebMD, if a wisdom tooth is misaligned or impacted, it needs to be removed. Misaligned wisdom teeth are not in the correct position and crowd other teeth. Some wisdom teeth come in horizontally, and some angle toward or away from their neighbors, the second molars. Pointing inward or outward are other indications of badly positioned teeth.Continue Reading
WebMD points out that when wisdom teeth are poorly aligned, they sometimes touch the tongue, inside of the cheek or the roof or bottom of the mouth. This leads to irritation or pain.
There are different variations of impacted wisdom teeth. Some never erupt through the surface and are completely surrounded by the gums and jawbone. In certain cases, wisdom teeth only partially break through the gums. This creates an entryway for bacteria, leading to infections, with symptoms such as pain, swelling, jaw stiffness and general illness. The flap of gum that covers the partially-raised tooth sometimes becomes inflamed and sore.
Other signs that wisdom teeth require removal are severe decay or gum disease, states WebMD. Since the teeth are so far back in the mouth, it is hard to reach the area for brushing and flossing. Therefore, the area becomes prone to problems. Difficulties with wisdom teeth typically affect people from 15 to 25 years old. Generally, individuals over 30 do not have issues with their wisdom teeth.Learn more about Dental
