Flossing teeth may be good for your cognitive health


New Delhi, Sep 27 | Dentists from all across the world have been recommending flossing teeth at least once a day. Turns out, it not only helps in preventing bad breath, avoiding cavities and gum disease but also boosts cognitive health.

While poor oral health has previously been linked to higher risk of heart disease, a recent meta-analysis of studies, published in the Journal of the American Medical Directors Association, showed that flossing may help against cognitive decline. The team analysed 14 studies, which included 34,074 participants and 4,689 cases with diminished cognitive function.

People with more tooth loss had 1.48 times higher risk of cognitive impairment and 1.28 times higher risk of dementia than the others. And with each additional missing tooth, the risk of cognitive impairment grows, the study showed. Moreover, adults with tooth loss were more likely to have cognitive decline if they did not have dentures.

“Given the staggering number of people diagnosed with Alzheimer’s disease and dementia each year, and the opportunity to improve oral health across the lifespan, it’s important to gain a deeper understanding of the connection between poor oral health and cognitive decline,” said Bei Wu, a professor in global health at NYU Rory Meyers College of Nursing and the senior study author, in a statement.

How does poor dental health affect brain cells?

“The bacteria that cause gingivitis (irritation, redness and swelling) also may be connected to Alzheimer’s disease. This species of bacteria, called Porphyromonas gingivalis, can move from the mouth to the brain. Once in the brain, the bacteria release enzymes called gingipains that can destroy nerve cells, which in turn can lead to memory loss and compromised cognitive health,” Sageer Azaz, HOD, Dental, Paras Hospitals, Gurugram told IANS.

According to a survey by the American Dental Association (ADA), only 16 per cent of adults floss their teeth. This percentage is much worse in the Indian context. Most people are not aware of the importance of oral hygiene and flossing.

“Most people in India are not aware that our teeth have five sides. Moreover, with brushing, we can only cover three sides. If the teeth are not flossed properly, then the food particles and bacteria may remain trapped between our teeth. It’s a simple step that not only helps in preventing bad breath but also avoiding cavities and gum disease,” explains Mohendar Narula, Founder and Chairman, MyDentalPlan Healthcare.

While brushing teeth after each meal may not be convenient, flossing after a meal is easy and can be done anywhere.

“Besides being a good oral hygiene practice, flossing can also help one maintain a healthy diet and lifestyle, as flossing after eating will make you less tempted to snack,” said Shuchin Bajaj, Founder Director, Ujala Cygnus Group of Hospitals.

San Francisco, Dec 6 | Musk hiring engineers to solve problems that affects people’s lives. Tesla founder and CEO Elon Musk on Monday tweeted that he is hiring Artificial Intelligence (AI) engineers who are passionate about solving day-to-day problems through AI.

“As always, Tesla is looking for hardcore AI engineers who care about solving problems that directly affect people’s lives in a major way,” Musk tweeted along with a link to apply for the job.

Interested candidates can apply by filling in fields like name, email, exceptional work done in software, hardware or AI, dropping their resume in the PDF format and hitting the Apply option.

As per the website, Tesla’s AI and Autopilot unit develops and deploys autonomy at scale in vehicles, robots and more.

“We believe that an approach based on advanced for vision and planning, supported by efficient use of inference hardware, is the only way to achieve a general solution for full self-driving and beyond,” the website read.

In a 2014 interview, Musk said he looked for “evidence of exceptional ability” in a potential employee, rather than a degree from a prestigious university.

“There is no need even to have a college degree at all, or even high school,” Musk said during an interview with the German automotive publication Auto Bild about his hiring preferences more broadly.

“If somebody graduated from a great university, that may be an indication that they will be capable of great things, but it’s not necessarily the case. If you look at, say, people like Bill Gates or Larry Ellison, Steve Jobs, these guys didna¿t graduate from college, but if you had a chance to hire them, of course that would be a good idea.”
