Brushing and flossing are great ways to prevent a wide range of cavities and gum disease. However, did you know that taking care of your smile can also protect your memory? It may seem like an odd correlation, but it’s essential to understand how maintaining your oral health can impact your brain. Here’s what you need to know and tips to keep your grin pristine.

So, How Can My Oral Health Impact My Memory?

The American Academy of Neurology published a study in the summer of 2023. They followed hundreds of older adults and found that those with gum disease and tooth loss often had higher rates of hippocampal shrinkage. This process is often associated with cognitive decline and Alzheimer’s disease, as this part of your brain is responsible for memory and learning.

While more research is needed to fully understand the link, these findings show that taking care of your teeth and gums can very well support your brain health as well.

How Can I Keep My Smile Free from Oral Health Issues?

With that being said, you may want to tighten your dental hygiene at home. Thankfully, it can be as easy as following these simple tips:

  • Brush twice a day for two minutes with fluoride toothpaste. This will remove plaque and help you avoid cavities.
  • Floss at least once every day to get rid of bacteria in places your toothbrush can’t effectively clean out.
  •  Eat a balanced diet that supports your oral and brain health in the long run. Doing so will also boost your immune system to fight things like inflammation.
  • Avoid using tobacco, since chewing and smoking it can increase your risk of gum disease.

What Can Your Dentist Do to Protect Your Smile?

The tips above are a great way to keep your smile strong while you’re at home, but you should remember to visit your dentist as well. Through consistent checkups and cleanings, they will be able to watch for early warning signs of various dental problems. If they notice anything worrying, you can get the prompt treatment you deserve to avoid serious complications.

You’ll also be able to get more personalized advice about your oral hygiene routine. That way, you feel confident about keeping your smile the best it deserves to be while also protecting your cognitive health over time.
