When you were in school, you might’ve learned that genetics can determine several traits, like hair and eye color. However, they can also affect your oral health. In fact, this may mean that “bad teeth” aren’t entirely your fault. That said, you may not fully blame your parents for your smile. Here’s what you should know about your genes and your grin.

How Do Genetics Affect Teeth?

Your genetics influence the appearance of your teeth and how much they are at risk of oral health issues. This is a breakdown of what can be impacted:

  • Tooth Color: Certain developmental conditions can make your enamel thinner, meaning the dentin underneath can poke through and cause a naturally gray or yellow tint.
  • Decay: Thin enamel can leave your smile more vulnerable to attacks from plaque in your mouth, making you more prone to cavities.
  • Gum Disease: If you have a stronger inflammatory response to bacteria, then your gums may swell and become irritated more easily.
  • Alignment: Crowding and crookedness can also be caused by your genetics, but orthodontics can help.
  • Oral Cancer: Certain genetic markers increase the risk of this dental problem. But routine checkups and cleanings can spot it early and give you the best shot at a successful recovery.

What Can You Do to Protect Your Teeth?

While genetics can leave you at a higher risk of certain oral health issues, that doesn’t mean you will definitely develop them. Instead, you should take steps to avoid any worries. By adding a few things to your routine, you can do your best to prevent trouble. These are several tips to keep in mind:

  • Brush with fluoride toothpaste twice a day for two full minutes. This cleans plaque on a large portion of your smile.
  • Floss once a day, as it gets into places your toothbrush can’t reach, such as between your teeth and underneath your gumline.
  • Break bad habits, such as smoking, using your teeth as tools, and chewing hard objects. They lead to increased enamel wear.
  • Eat a balanced diet to provide your body and immune system with the vitamins and nutrients they need to stay strong.
  • Limit your sugar intake. These particles feed bacteria in your mouth, so rinse with water if you do have anything sweet.

In the end, don’t forget to visit your dentist. They are dedicated to helping you have a stronger smile with routine checkups and cleanings. That way, your “bad teeth” aren’t a worry.
