Three Rare Dental Conditions

Posted by Editor in , on October 31, 2017


Just like any other part of the body, the mouth (and specifically the teeth) can present some rare and seemingly spooky conditions. Anodontia, also known as hypodontia, happens when teeth are congenitally missing. It’s hereditary and easy to spot when the primary (or baby) teeth erupt—or not! With anodontia, a person might have “total anodontia” or just a few teeth missing (hypodontia). Hypodontia includes the shift in bone development in the jaws, so large spaces between teeth are more commonly seen than what looks like a single missing tooth. Men have both conditions more commonly than women. “Wisdom teeth” are the most common to be missing with hypodontia, but that’s not a surprise to many patients. A lot of us know someone who doesn’t have all of their wisdom teeth.

There’s also a condition called amelogenesis imperfecta or dentinogenesis imperfecta. In the former, it’s also a hereditary disorder where the tooth enamel is incorrectly formed. In the latter, there are issues with the enamel properly hardening (or mineralization) to a normal degree. Whether more or less enamel hardening than normal, these conditions can cause serious side effectives. Enamel might flake off and leave teeth extremely sensitive to heat or cold and weak. So-called cosmetic dentistry such as a bond, crown or permanent dentures might be recommended.

Finally, supernumerary teeth is a condition where there are extra permanent teeth in the body. They may or may not erupt. Recently, there was a viral YouTube video about “shark boy,” a young boy with this condition. However, unlike an actual shark, a human’s supernumerary teeth can happen anywhere in the mouth. Most of these teeth are smaller and triangular (like a shark’s) with short roots. They’re most common in the upper, back jaw and in many cases are a relatively easy extraction for a dentist.

Regular dental checkups are the best way to spot red flags early and stay on top of preventative measures for great oral hygiene.
