New Study Links Oral Bacteria to Declining Brain Health

Physician reviewing brain scansAlthough the two are often viewed separately, your oral health and general wellness are connected. Many health issues can increase your risk of dental problems and vice versa. Researchers have already found several links between gum disease and various health conditions, including heart disease, preterm delivery, and diabetic complications. However, new research has found another connection. Poor oral health can lead to a decline in brain health. Here’s what you need to know to keep your mouth and brain healthy.

Half of Americans Have Gum Disease

Cavities aren’t the only threat to your dental health. 50% of adults over the age of 35 have a form of gum disease, according to the Centers for Disease Control and Prevention. The infection is caused by bacteria in plaque and tartar buildup from poor oral hygiene. Gingivitis is the earliest stage of the infection, which is easy to treat. However, with no treatment, it can progress to advanced periodontitis, a leading cause of tooth loss. Not only can it cause missing teeth, but bacteria from gum disease may enter your bloodstream through the pressure of chewing, which can have adverse complications for your overall health.

Gum Disease May Shrink Your Brain

The American Academy of Neurology recently published the results of a study that found a connection between gum disease and Alzheimer’s. According to the results, tooth loss and gum disease were connected to brain shrinkage in the hippocampus, which plays a role in memory. Participants with severe gum disease experience an increased rate of brain shrinkage. Although the study doesn’t prove that gum disease causes Alzheimer’s, there is an obvious connection. Previous studies have also found oral bacteria in brain tissue samples from deceased Alzheimer’s patients.

Protect Your Gum and Brain Health

You can keep your brain and mouth healthy by committing to good oral hygiene. You can prevent gum disease by following a few tips:

  • Brush Twice Daily: Your toothbrush removes plaque and food residue. The American Dental Association recommends brushing your teeth at least twice a day using a soft-bristled toothbrush and fluoride toothpaste. Clean all surfaces for at least 2 minutes, and don’t forget to brush your tongue where bacteria can hide.
  • Floss Daily: Your toothbrush is effective, but it can’t clean everywhere in your mouth, like between teeth. Use traditional floss or a waterflosser every day to remove the buildup your toothbrush can’t reach.

Besides keeping your mouth clean at home, visit your dentist every 6 months for a cleaning and checkup. If you develop signs of gingivitis, like red, swollen, or bleeding gums, don’t wait to schedule an appointment with your dentist.
