Gum disease may have ties to Alzheimers

Gum disease may have ties to Alzheimers

Oral bacteria from poor dental hygiene has been linked to brain tissue degeneration, a finding that shows a potential association between gum disease and Alzheimer’s disease. Researchers examined samples from the brains of patients with and without dementia and found lipopolysaccharide, a component of Porphyromonas gingivalis, an oral bacterium, in four out of 10 Alzheimer’s disease brain samples. It was not found in any samples from the brains of people who did not have Alzheimer’s disease.

“This clearly shows that there is an association between oral bacteria and Alzheimer’s disease, but not causal association,” says Lakshmyya Kesavalu, Associate Professor of Periodontology at the University of Florida.

The researchers say the study, published in the Journal of Alzheimer’s Disease, is the first to show a link between the existence of the oral bacterium component lipopolysaccharide and Alzheimer’s disease. (Rhodenizer-Florida, 2014)

Dr. Buchanan advises patients to brush their teeth for 2 minutes twice a day and use a waterpik. She also recommends to floss regularly to prevent bacteria plaque build-up between teeth. Be sure to visit your dentist for regular cleanings twice a year too!

  1. 1. Toothbrush & Toothpaste – Yes, we know this is a little bit of a hassle but make sure you brush and floss after lunch to keep your smile healthy. Oral hygiene is always important but it’s ESPECIALLY important when you have braces. 
  2. 2. WaterPik - if you have a portable one take it with you 
  3. 3. Mirror – We recommend keeping a compact mirror in your locker and/or backpack so you can check out your braces if something feels funny. 
  4. 4. Wax – Keep a case of wax in your backpack in case you have a pokey wire or any cheek irritation. 
  5. 5. Rubber Bands – Don’t get behind on your treatment! Make sure you have spare rubber bands in case one breaks at school and to replace after lunch. 
  6. 6. Retainer Case – We see it ALL the time…Where did my retainer go? I had it on my lunch tray…Whoops! It’s in the trash! Avoid having to dig through trash and the added expenses of new retainers. Keep your retainer in a retainer case whenever it’s not in your mouth! 
  7. 7. Mouth Guard – If you play contact sports, make sure you wear your mouth guard to protect your teeth and braces. Studies have shown that athletes are 60 times more likely to damage teeth when NOT wearing a mouth guard!

Floss Like A Boss

Floss Like A Boss
  1. Floss Threaders: These little lassos help you thread floss under the wire so you can get down to the gum line and all the way between the teeth. 
  2. Water Pik: Water flossing removes trapped food from dental braces. 
  3. A Proxabrush: Sometimes referred to as “go-betweens,” these look like little pipe cleaners or Christmas tree brushes and are used just like you’d expect—they “go between” braces and teeth to clean food and plaque. They don’t replace floss, but they are great for using on-the-go to get food from between your teeth and also do a great job cleaning the brackets themselves. 
  4. Patience and Time: Patience might be the most important part of your brushing routine with braces. It takes a while to learn how to maneuver around braces with floss and other tools! Over time you will become more skilled and the process will become easier, but it’s still a good idea to set aside 10 minutes or so, morning and night, to make sure you do a really great job on your teeth. Taking these tips into account, you’ll be sure to be congratulated by Dr. Buchanan.
