How Genetics are Affecting Your Teeth

Posted by: Dr. Sirakian Categories: Dentistry, Oral Health

You may have stellar brushing, flossing, and rinsing habits, but it is genetics that plays the leading role in your oral health. About 60% of the risk for tooth decay comes from genetic factors. Tooth decay is the most common chronic worldwide disease and we only have partial control over it. While you should continue to brush multiple times a day and floss daily, here is what you should know about the role that genetics plays in oral health. Scientists have found that these things that play a role in tooth decay are linked to genetics.

Sweet Preference
Mary L. Marazita, director of the Center for Craniofacial and Dental Genetics at the University of Pittsburgh School of Dental Medicine found that there are gene variants that show a range of “sweet preference.” The stronger your genetic preference is for sweets, the more likely you are to develop tooth decay. So, it turns out we are not all candy-loving maniacs, but that some of us have a stronger genetic preference for it, which can affect your teeth.

Tooth Enamel
Some people simply have softer tooth enamel than others. Genes play a major role in developing the structure of enamel, so if you have weak enamel, it is due to your genes. Weakened enamel makes it easier for bacteria and acids to cause cavities and decay.

Saliva Strength
Saliva production is key to keeping your mouth healthy. Saliva washes away bacteria and food particles in your mouth that can cause decay. Genetically speaking, some of us are better at producing saliva than others. Low saliva production can lead to cavities, decay, and gum recession, so if you lack the genetic variant for high saliva production, then your mouth could suffer.

While genetics does play a factor in your oral health, the other 40% risk of tooth decay can be lowered by brushing and flossing regularly. So, even if your family has a history of soft enamel paired with a sweet tooth, continue to brush, floss, and take regular trips to the dentist.

The Battleground at the Root of an Infected Tooth

When a tooth becomes severely infected, bacteria can spread through the inner structure of the tooth and reach the tissues around the root. When this happens, it can lead to a painful infection at the tip of the root, known as a periapical lesion (often referred to as a dental abscess). At this stage, patients […]

Everything in Moderation (Including Fluoride)

Fluoride plays an important role in building strong, healthy tooth enamel. However, like many good things, too much fluoride—especially during childhood—can cause a condition called fluorosis. What Is Dental Fluorosis? Dental fluorosis most often develops in children while their teeth are still forming, typically up to about age 8 or 9. It appears as: Fluorosis […]

Please, Please, Please Don’t File Down Your Teeth

A disturbing trend has been making the rounds on TikTok: people—mostly teens—filing down their front teeth to make them look “even” or “straight.” We can’t believe we have to say this, but please don’t do it. Or, to borrow a line that feels painfully appropriate right now: “Please, please, please…” don’t embarrass yourself (or your […]
