MOST PEOPLE WILL develop a total of twenty baby teeth that are gradually replaced by a total of thirty-two adult teeth. Sometimes those teeth don’t all appear, a condition called hypodontia. In even rarer cases, all the normal teeth will be present, plus at least one extra! These extra teeth are supernumerary teeth, and the condition is called hyperdontia. Why Do Extra Teeth Form? There are two main competing theories about what causes supernumerary teeth. One possibility is that an individual tooth bud might divide abnormally and result in two teeth instead of one. Another is that extra teeth could result from hyperactivity in the dental lamina (the tissue in our jaws that forms tooth buds). Heredity might also play a role. Supernumerary teeth can come in various forms. They might be conical (peg-shaped), tuberculate (with [...]

ORAL CANCER IS A SUBJECT we’d all prefer not to have to think about, but it’s critical to have a basic understanding of risk factors and symptoms. More than 50,000 people in the U.S. were diagnosed with oral cancer last year, and that number is expected to rise. That’s why, in honor of Oral Cancer Awareness Month, we’re dedicating a blog post to giving our patients the tools they need for early detection. Oral Cancer Risk Factors There are several risk factors that increase a person’s chances of developing oral cancer. Some of them are out of our control, such as age and sex. Men are twice as likely as women to develop oral cancer, and it is far more common in people over 45. But there are plenty of risk factors that we [...]

YOU’VE PROBABLY NOTICED that your teeth aren’t all the same shape, but do you know the reason? Humans have four different types of teeth, and they each serve specific purposes, both in helping us chew and in giving us our beautiful smiles! Types Of Teeth And What They Do The reason we need so many different types of teeth is that we are omnivores, which means we eat both plants and meat. We need teeth that can handle all of our favorite foods! Incisors At the very front of the mouth, the top four and bottom four teeth are the incisors. The middle ones are central incisors, while the ones on the sides are lateral incisors. Incisors are built for slicing. When we take a bite out of an apple, for instance, our incisors shear [...]

SPRING IS IN THE AIR…and that means so are allergies. Seasonal allergies affect millions of people every year, but did you know that they can also affect oral health? Why Do We Get Seasonal Allergies? While there are plenty of allergens that can make us sneeze year round, such as dust and pet dander, seasonal allergies typically flare up twice a year: in the spring and the fall. This can mean long months of congestion, an itchy nose, mouth, eyes, or throat, puffy eyes, sneezing, and coughing for people with allergies. The reason our allergies act up the most during spring and fall is that trees and grass pollinate throughout the spring, while ragweed pollinates in the fall. Mold will also send out spores around the same time. Allergic reactions, including seasonal allergies, [...]

IT’S ONE THING TO lose a tooth, whether through poor oral hygiene, accident, or oral surgery. A tooth not growing in where it should is something else. Between 2-4 percent of the population will have at least one tooth missing from their adult set. This condition is called congenitally missing teeth or hypodontia. In the much rarer event that the full set of teeth is missing, it’s called anodontia. It’s All About Genes The most common teeth to be affected by this condition are wisdom teeth, upper lateral incisors, and lower second premolars. Since wisdom teeth are often removed anyway, not having them in the first place can save you a lot of hassle, but those incisors and premolars are more necessary. Genetics are almost always the culprit behind hypodontia, which is [...]
