Your teeth are designed to last for a lifetime. Unfortunately, there are various issues that can impact the longevity of your smile, like tooth decay and gum disease. While you may think your home oral hygiene habits are the only factors to influence your dental health, there is another predictor of complications you may face. Your genes can play a role in the development of certain oral health problems. Genetic testing can determine if you have markers for specific conditions that can hurt the health of your smile. No matter the results of the testing, your dentist can help you maintain healthy teeth and gums through personalized treatments.
