How Losing Teeth Can Affect Your Memory

Research suggests that tooth loss could be linked to memory loss. This may seem like an odd relationship. However, the science behind this theory says that the memory loss may be because of reduced sensory input to the nervous system through the connective fibers that attach the teeth to the bone. The research also suggests that people who tend to avoid nutrient dense foods; proteins and calories that keep the brain active will also lose teeth.

There are several sensory impulses sent to our brain with the movement of the jaw and teeth. These impulses are fed to the brain in the area that forms and retrieves memories. People who have fewer teeth send fewer signals to this region of the brain called the hippocampus. Individuals were tested on their performance on memory tests where they recall events from the past. According to this study, older people scored higher on this test who had most of their own teeth than those without.

One way the study can be interpreted is through an individual’s chewing ability. Chewing actually increases blood flow to the brain, which in turn increases activity to help with function and recall memories. It is also possible that brain activity changes due to diet. Those who have less teeth or use dentures tend to eat foods that are not as nutrient dense and full of vitamins. This too can affect how the brain works. Nutrient dense foods such as vegetables and fruits promote healthy brain activity, so it’s important to eat them.

It’s important for individuals to maintain proper oral hygiene to maintain optimal health. If tooth loss does occur, dental implants could be an option. These implants function just as natural teeth do. While there is a gradual process to getting these implants, it will be well worth a patient’s time. This could help them avoid issues such as memory loss or a poor diet.

There is no alternative to eating healthy. Patients who receive prosthetic teeth should be encouraged to eat a wide variety of foods. This will ensure that they stay as healthy as possible and avoid any issues associated with tooth decay, tooth loss or even memory loss.
