When you think of genetics, characteristics such as hair and eye color, height and weight, or athletic ability might come to mind. But genes can also affect various less visible aspects, including your oral health. Knowing whether you have a genetic predisposition to particular health concerns is vital to prevention. Here’s a guide to understanding why it’s important to discuss family history with your dentist. 

Which Oral Health Issues Have a Genetic Predisposition? 

There are a few oral health issues that can be linked to genetics, including: 

• Cavities: If you get cavities frequently despite practicing good oral hygiene, your ancestors may be to blame. Oral health studies have found mixed results, with some suggesting a genetic predisposition could increase your risk of cavities by 20% to 80%. Whatever the percentage, variations of the gene beta-defensin are linked to cavities.
• Gum Disease: Gum disease, or chronic inflammation of the gums, affects nearly half of American adults. It is often a result of poor oral hygiene, smoking, or an uncontrolled medical condition. But research suggests there is about a 50% chance of gum disease having a genetic component. 
• Oral Cancer: As with many types of cancer, oral cancer can be caused by several factors. This includes environment, lifestyle, and genetics. Although behaviors such as tobacco use and excessive drinking can increase risk, there are also specific genetic markers in xenobiotic-metabolizing enzymes that are associated with a higher risk. 

Why It’s Important to Know Your Risk 

Finding out you have a genetic predisposition to an oral health issue might be unpleasant, but the good news is there are steps you can take to reduce your risk. Talk to family members to ascertain if there is a history of such problems. Then talk with your dentist to strategize. While you can’t change your genes, other factors are within your control. Your dentist might suggest quitting smoking and drinking, for example, if you are at high risk of oral cancer. Or, if you are predisposed to cavities, they may prescribe a fluoride-based mouthwash. Your dentist may also recommend more frequent screenings and cleanings to detect any issues early on when the likelihood of effective treatment is higher.
