You’ve probably already noticed that certain traits can be handed down from generation to generation. Perhaps you have your grandfather’s curly hair, or your grandmother’s cheekbones. But what about when it comes to your oral health? Is it possible to get your dad’s weak enamel or the same gaps in your smile as your mother? Here’s a closer look at the role genetics play in your teeth and gums, and which problems are most likely environmental.
Your Tooth Color
If your teeth are yellower than you’d prefer, it may not have much to do with your diet. It can sometimes be caused by the density of your enamel, which is determined by genetics. Although it is still possible to stain or discolor your teeth with your diet and bad oral habits like smoking, if you take great care of your smile and still have yellow teeth, your family could be on the hook for this one!
When Your Teeth Erupt
Although most children’s teeth develop in the same order, exactly when they erupt is determined by genetics. So, if your teeth showed up later than they should have, your children’s may take a little extra time emerging, too.
Your Spacing and Alignment
Because your genes determine the size and shape of your jaw, the spacing and alignment of your teeth is genetic, too. In fact, you could even have the same gaps in your teeth as your ancestors do, and if you need braces, that’s often thanks to someone in your immediate family.
Understanding Genetic Predisposition
A genetic predisposition to a condition doesn’t mean you will definitely experience it, but it does mean you should keep an eye out for it. For example, if impacted wisdom teeth are common on your dad’s side, you could develop them as well, but you might not. Still, it doesn’t hurt to give your dentist a head’s up so she can be on the lookout for them as you or your child’s mouth grows.
Environmental Factors
In addition to genetic predisposition, there are many environmental factors that can seem hereditary but really aren’t. Cavities, for example, are caused by bacteria which can be transferred from person to person by kissing, sharing utensils and cups, and even using each other’s toothbrushes. Therefore, if someone in your household has high oral bacteria levels, it can easily be transferred to others if they’re not careful. So, while it may seem like you get frequent cavities like your dad because of your genes, it could just be that you drank from the same cup as him and now have more oral bacteria!
Remember, although physical features like the density of your enamel and the spacing of your teeth can be genetically influenced, your individual oral hygiene is entirely under your control. Thus, be sure to maintain an excellent oral hygiene routine, and let your dentist know if your family has any oral health issues that could cause problems for you and your family’s smiles down the road.
