Supernumerary Teeth
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 multiple cusps), supplemental (duplicates of normal teeth), or odontoma (a mass of dental tissue that doesn’t quite form a tooth).
Don’t Forget To Clean That Tongue!
YOU HEAR ALL THE TIME about the importance of brushing your teeth for two minutes twice a day, and you hear almost as often about the importance of daily flossing. What you probably don’t hear a lot is that, if we want to maintain good oral health and hygiene, it’s also important for us to clean our tongues. Why Should We Clean Our Tongues? The tongue is one of the most bacteria-covered spots in our bodies. A tongue doesn’t just have taste buds on it, it also has crevices, elevations, and all sorts of tiny structures that bacteria will hide between unless physically removed. Letting all this bacteria sit and multiply can cause bad breath or halitosis, as well as tooth decay on the inner surfaces of the teeth. This is why it’s so important to regularly clean our tongues — so we can get rid of all the unwanted bacterial buildup! Another benefit to
Five Types Of Dental Fillings
IT’S NEVER A GREAT feeling when the dentist tells you that you have a cavity, especially when you’ve been diligently brushing and flossing to keep your teeth healthy. The next step after a cavity is discovered is typically a dental filling. Fillings come in several different materials that have their own advantages and disadvantages, so let’s take a look! 1. The Classic: Amalgam Fillings Amalgam fillings are what you might think of as “silver” dental fillings, though they’re actually composed of a mixture of tin, copper, silver, and mercury. They have been used for over 150 years! The reason dentists have been using them for so long is that they are strong and long-lasting, and they are also the least expensive option. However, they’re very noticeable and tend to darken over time, so if you want something that blends in, amalgam fillings probably aren’t the ones you want. 2.

Night Guards For Teeth Grinding
HAVE YOU EVER woken up with a sore jaw, tooth pain, or a headache? These are common symptoms of sleep bruxism, or teeth-grinding. The American Dental Association estimates that 10-15 percent of adults struggle with sleep bruxism, and children can experience it too. Because it happens during sleep, it can be difficult to control or stop. One way to protect the teeth from the damaging effects of grinding is to wear a night guard. What Night Guards Are Night guards come in hard, medium, and soft varieties, with the soft ones resembling mouth guards for sports and hard ones resembling clear plastic retainers, though they’re much sturdier and you usually only need one for the upper teeth. Wearing a night guard provides a cushioning effect so that the upper and lower teeth can’t wear away at each other. It will protect your teeth from external damage caused by grinding, such as chipping and erosion, but
The Anatomy Of A Tooth
TEETH ARE A LOT more complicated than they might seem from the outside, which is why we’re using this post to provide a brief dental anatomy lesson. Now let’s dive right into the structure of a tooth! The easiest way to do this will be to divide that anatomy into two main categories: the crown and the root. Something To Chew On: The Crown The crown of a tooth is the part that is above the gumline. It consists of three layers. The outermost layer is the enamel, which is the hardest substance in the human body. It needs to be so that we can chew our food! However, enamel isn’t made of actual cells, which means it can’t repair itself if it wears down. Good brushing and flossing habits, regular dental visits, and avoiding sugary or acidic food and drink will help preserve that enamel for life. Beneath the enamel is dentin, which is
The Different Types Of Teeth
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 off a tasty chunk of fruit, but they aren’t the teeth we actually chew with. Canines Next to the lateral
Seasonal Allergies And Your Oral Health
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, are the result of our immune systems going into overdrive in response to these allergens.

Fighting Back Against Oral Cancer
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 can control, the biggest of which is tobacco. A whopping 85 percent of oral cancer cases are linked to some kind
An Eating Disorder’s Impact On Oral Health
THE FOOD WE EAT provides our bodies with the building blocks to maintain healthy cells, tissues, and organs and the energy to work, learn, and do the activities we love. It is crucial that we eat enough food (and preferably the right kinds) in order to keep everything working properly, which is why eating disorders are such a serious threat. Malnutrition And Overall Health Eating disorders are a group of psychological disorders that can have a devastating impact on the mental, physical, and emotional health of those who suffer from them. No system in the body is spared, and that includes oral health. That’s why we want to educate our patients on the dangers of eating disorders and encourage anyone suffering from one to seek help returning to healthy eating habits. Anorexia: Starving The Oral Tissues Anorexia Nervosa is an eating disorder characterized by extremely restricted food intake, and may also involve
Congenitally Missing Teeth
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 why it tends to run in families. Missing teeth could be the only issue, or they could be the result
