Can You Blame Your Parents for Your “Bad Teeth”?

When you were younger, you might’ve learned how genes can determine things like hair color, eye color, and your height. However, did you know they can also influence traits in your smile? That means that “bad teeth” may not be entirely your fault, but it’s a bit more nuanced than just that. Here’s what you need to know about your grin and your genetics.

Are My Parents to Blame for My “Bad Teeth”?

As was mentioned above, your genes come into play when determining how your smile looks and whether it’s more susceptible to dental problems. This is a breakdown of a few things that can be affected:

  • Tooth Color: The outer layer of your teeth is your enamel. There are a few dental developmental conditions that can make it thinner than it should be. The dentin underneath may be more exposed, leading to a naturally yellow or even gray look.
  • Decay: Building off the point above, you may also be at a higher risk of cavities, as plaque will be able to more easily cause problems.
  • Gum Disease: A few people might have a stronger reaction to bacteria, meaning the soft tissues in their mouth might become inflamed more often.
  • Alignments: If your jaw is too small, then your teeth may not have enough room to lay out as they should and become crowded.
  • Oral Cancer: A couple of patients might have genetic markers that increase their risk of this oral health issue. Thankfully, routine checkups can help you prevent it or catch it as early as possible.

So, How Can I Take Care of My Teeth?

Although you may have more problems with your teeth because of your genetics, that doesn’t mean you should just deal with them. In fact, you can avoid trouble by properly taking care of your grin, even if you are predisposed to them. Here are a few things you can do:

  • Brush twice daily with fluoride toothpaste for two minutes to remove plaque.
  • Floss at least once a day to get into nooks and crannies your toothbrush can’t reach.
  • Break bad oral habits like smoking, using your teeth as tools, and chewing hard objects. They can damage and wear down your enamel.
  • Eat a smile-friendly diet full of nutrients and vitamins your mouth needs to stay healthy.
  • Limit sugar to lower your risk of cavities. You can still have it in moderation, but rinse with water afterward to wash away any lingering particles.
  • Don’t forget to keep up with visits to your dentist. They will be able to keep an eye out for any red flags and give you the prompt treatment you need. That way, “bad teeth” can’t cause any problems, and you flaunt a smile you love.
