This odd dental habit could spark heart health risks, experts warn

Searches for “tongue scraper” have almost doubled in the last two decades, according to Google Trends. Some experts, however, have warned about potential risks.

The practice of tongue-scraping (or tongue-brushing) has existed as a means of dental health for hundreds of years. 

While earlier studies concluded that scraping the tongue can improve one’s sense of taste in as little as two weeks, some have raised concerns about potential heart health risks associated with the practice.

HERE’S HOW YOU SHOULD BE CLEANING YOUR TEETH, ACCORDING TO A DENTIST

“There’s always been a strong association between good oral hygiene and heart health,” Dr. Bradley Serwer, an interventional cardiologist and chief medical officer at VitalSolution, an Ingenovis Health company, told Fox News Digital.

“Gingivitis or a bad gum infection has been known to cause problems with the heart on many different levels,” said the Maryland-based doctor.

Despite the potential benefits, Serwer and others have warned of a little-known cardiac risk associated with the practice.

What is tongue-scraping?

Tongue-scraping (or brushing) is the process of cleaning the tongue to keep bad bacteria, food debris and dead cells from accumulating on its surface, according to Cleveland Clinic.

Beyond brushing with a toothbrush, specific tongue-scraping tools — available at pharmacies for as little as $8 — offer an easy way to get rid of plaque and other unwanted build-up.

“Brushing is OK to do, but think about it this way — if your carpet is dirty and you scrub it, the dirt’s going to get embedded down in there,” said one dental hygienist. (iStock)

Gentle tongue-scraping performed up to once a day is recommended for adults to help remove bacteria and freshen breath, according to Dr. Whitney White of Aspen Dental.

“When patients ask, I typically recommend a metal tongue scraper, as they are the best for hygienic reasons to keep clean,” White, who is based in Nevada, told Fox News Digital.

Another expert, Ohio-based dental hygienist Tenika Patterson, told Cleveland Clinic, “Tongue-scraping can do a better job at removing that plaque and bacteria from the tongue’s surface.”

“Brushing is OK to do, but think about it this way — if your carpet is dirty and you scrub it, the dirt’s going to get embedded down in there,” she said.

“But if you scrape it, it’s going to come right off the surface.”

Link to heart health

The concern with tongue-scraping is that it can cause “macroscopic cuts” on the tongue, which potentially can introduce bacteria into the bloodstream, Serwer cautioned.

Any time bacteria enters the bloodstream, there is an increased risk of endocarditis, which is an infection of the heart valves.

While tongue-scraping can be good for oral health, it’s important not to overdo it, Dr. White advised.

“While gentle, regular scraping helps remove harmful bacteria, doing it too often or too aggressively can disrupt the balance of good microbes on your tongue — some of which help produce nitric oxide, a compound that’s important for heart health,” White said.

‘Not a substitute’

“The most important thing a person can do is to stay on top of oral hygiene,” Serwer recommended. 

“Regular visits to the dentist, brushing and flossing can help ensure healthy gums and teeth.”

While brushing teeth and flossing can also introduce bacteria, those are outweighed by the benefits of maintaining healthy gums, experts agree. (iStock)

While brushing teeth and flossing can also introduce bacteria, those are outweighed by the benefits of maintaining healthy gums, experts agree.

In contrast, “the benefits of tongue scraping are quite minimal,” Serwer said.

For those who wish to continue tongue-scraping, White emphasized that less can be more.

“Since your oral health is connected to your overall health, it’s best to scrape your tongue in moderation to keep both your mouth and body in balance,” she advised.

“However, it is not a necessary step in your oral health routine, and should not be a substitute for twice-daily brushing with fluoride toothpaste and daily flossing.”

Heart disease threat projected to climb sharply for key demographic

NEWYou can now listen to Fox News articles!

A new report by the American Heart Association (AHA) included some troubling predictions for the future of women’s health.

The forecast, published in the journal Circulation on Wednesday, projected increases in various comorbidities in American females by 2050.

More than 59% of women were predicted to have high blood pressure, up from less than 49% currently.

The review also projected that more than 25% of women will have diabetes, compared to about 15% today, and more than 61% will have obesity, compared to 44% currently.

As a result of these risk factors, the prevalence of cardiovascular disease and stroke is expected to rise to 14.4% from 10.7%.

Not all trends were negative, as unhealthy cholesterol prevalence is expected to drop to about 22% from more than 42% today, the report stated.

Dr. Elizabeth Klodas, a cardiologist and founder of Step One Foods in Minnesota, commented on these “jarring findings.”

“The fact that on our current trajectory, cardiometabolic disease is projected to explode in women within one generation should be a huge wake-up call,” she told Fox News Digital.

NEARLY 90% OF AMERICANS AT RISK OF SILENT DISEASE — HERE’S WHAT TO KNOW

“Hypertension, diabetes, obesity — these are all major risk factors for heart disease, and we are already seeing what those risks are driving. Heart disease is the No. 1 killer of women, eclipsing all other causes of death, including breast cancer.”

Klodas warned that heart disease starts early, progresses “stealthily,” and can present “out of the blue in devastating ways.”

The AHA published another study on Thursday revealing one million hospitalizations, showing that heart attack deaths are climbing among adults below the age of 55.

The more alarming finding, according to Klodas, is that young women were found more likely to die after their first heart attack than men of the same age.

“This is all especially tragic since heart disease is almost entirely preventable,” she said. “The earlier you start, the better.”

Children can show early evidence of plaque deposition in their arteries, which can be reversed through lifestyle changes if “undertaken early enough and aggressively enough,” according to the expert.

Klodas suggested that rising heart conditions are associated with traditional risk factors, like smoking, high blood pressure, high cholesterol, diabetes, obesity and a sedentary lifestyle.

Doctors are also seeing higher rates of preeclampsia, or high blood pressure during pregnancy, as well as gestational diabetes. Klodas noted that these are sex-specific risk factors that don’t typically contribute to complications until after menopause.

The best way to protect a healthy heart is to “do the basics,” Klodas recommended, including the following lifestyle habits.

Klodas especially emphasized making improvements to diet, as the food people eat affects “every single risk factor that the AHA’s report highlights.”

“High blood pressure, high blood sugar, high cholesterol, excess weight – these are all conditions that are driven in part or in whole by food,” she said. “We eat multiple times every single day, which means what we eat has profound cumulative effects over time.”

“Even a small improvement in dietary intake, when maintained, can have a massive positive impact on health,” a doctor said. (iStock)

The doctor also recommends changing out a few snacks per day for healthier choices, which has been proven to “yield medication-level cholesterol reductions” in a month.

“Keep up that small change and, over the course of a year, you could also lose 20 pounds and reduce your sodium intake enough to avoid blood pressure-lowering medications,” Klodas added.

“Women should not view the AHA report as inevitable. We have power over our health destinies. We just need to use it.”

Common vision issue linked to type of lighting used in Americans’ homes

Common vision issue linked to type of lighting used in Americans’ homes

NEWYou can now listen to Fox News articles!

Nearsightedness (myopia) is skyrocketing globally, with nearly half of the world’s population expected to be myopic by 2050, according to the World Health Organization.

Heavy use of smartphones and other devices is associated with an 80% higher risk of myopia when combined with excessive computer use, but a new study suggests that dim indoor lighting could also be a factor.

For years, scientists have been puzzled by the different ways myopia is triggered. In lab settings, it can be induced by blurring vision or using different lenses. Conversely, it can be slowed by something as simple as spending time outdoors, research suggests.

Nearsightedness occurs when the eyeball grows too long from front to back, according to the American Optometric Association (AOA). This physical elongation causes light to focus in front of the retina rather than directly on it, making distant objects appear blurry.

Researchers at the State University of New York (SUNY) College of Optometry identified a potential specific trigger for this growth. When someone looks at a phone or a book up close, the pupil naturally constricts.

COMMON VISION ISSUE COULD LEAD TO MISSED CANCER WARNING, STUDY FINDS

“In bright outdoor light, the pupil constricts to protect the eye while still allowing ample light to reach the retina,” Urusha Maharjan, a SUNY Optometry doctoral student who conducted the study, said in a press release.

“When people focus on close objects indoors, such as phones, tablets or books, the pupil can also constrict — not because of brightness, but to sharpen the image,” she went on. “In dim lighting, this combination may significantly reduce retinal illumination.”

High-intensity natural light prevents myopia because it provides enough retinal stimulation to override the “stop growing” signal, even when pupils are constricted. (iStock)

The hypothesis suggests that when the retina is deprived of light during extended close-up work, it sends a signal for the eye to grow.

In a dim environment, the narrowed pupil allows so little light through that the retinal activity isn’t strong enough to signal the eye to stop growing, the researchers found.

In contrast, being outdoors provides light levels much brighter than indoors. This ensures that even when the pupil narrows to focus on a nearby object, the retina still receives a strong signal, maintaining healthy eye development.

The team noted some limitations of the study, including the small subject group and the inability to directly measure internal lens changes, as the bright backgrounds used to mimic the outdoors made pupils too small for standard equipment.

Researchers believe that increasing indoor brightness during close-up work could be a simple, testable way to slow the global nearsightedness epidemic. (iStock)

“This is not a final answer,” Jose-Manuel Alonso, MD, PhD, SUNY distinguished professor and senior author of the study, said in the release.

“But the study offers a testable hypothesis that reframes how visual habits, lighting and eye focusing interact.”
