DNA & Dental Drama: Can “Bad Teeth” Run in My Family?

You may already know how genes play a role in your phenotype. They can determine what color your hair and eyes are while dictating how tall you’ll be. But did you know that they can also affect your smile? While you might be able to blame “bad teeth” on your heritage, it is also dependent on your dental routine! Keep reading to learn how your family tree comes into play with your grin.

So, Do My Genetics Affect My Oral Health?

Genetics can influence your pearly whites in several ways. You won’t be born with cavities, but instead, they may make you more susceptible to them compared to your peers. Here is how heritage can affect your teeth:

• Tooth Color and Decay: For some people, the enamel outer layer may be naturally thinner. This can expose the yellow dentin underneath, making your smile look a bit discolored. Since it’s not as thick as it should be, the bacteria in your mouth can more easily erode it and cause decay or an infection.
• Alignment: Genes can also determine the size of your jaw, which can influence the position of your pearly whites. Some patients may experience crowding, gaps, or malocclusions (such as an overbite).
• Oral Cancer: There are certain genetic markers that have been found that increase your risk of this condition. While it may be scary to think about, there are things you can do to prevent it or catch it early.

What Can I Do to Take Care of My Teeth?

Although you may be tempted to phone your parents and blame them for your teeth, it’s not entirely their fault! While you may be predisposed to some oral health issues, you have to do your part in preventing them. One of the best ways you can do this at home is by following proper dental hygiene.

Brushing twice, flossing at least once, and rinsing with antibacterial mouthwash can help clean out harmful plaque from your mouth. Additionally, you should stop any bad habits, such as tobacco use or chewing on hard objects (like ice or pen caps). Eating a balanced diet without much sugar can help give your body the boost it needs to stay strong and reduce your risk of cavities.

It’s also crucial to keep up with visits to your dentist. They are trained to spot the signs of dental problems, like decay and oral cancer, and fix them right away. By catching them early, you give yourself the best shot at a successful treatment. While “bad teeth” may run in your family, it’s important to take good care of your smile and keep it strong for years to come.
