It’s a morning routine familiar for many of us: Get that mouth clean immediately after breakfast by using a harsh toothpaste applied by an abrasive toothbrush, followed by a rinse with a mouthwash so strong it makes you wince.
Dr. Kami Hoss winces, too, when he hears patients describe these habits.
They’re some of the reasons why so many people have poor oral health, which in turn affects all other aspects of their health, from physical to mental, the dentist writes in his book, “If Your Mouth Could Talk: An In-Depth Guide to Oral Health and Its Impact on Your Entire Life.”
“Statistically, our mouths are incredibly unhealthy right now as a society. With all these advancements in science and technology and medicine, you would think at this point dentists wouldn’t have anything to do,” Hoss, who is the co-founder of The Super Dentists in San Diego, California, told TODAY.
“But oral health hasn’t gotten any better in the last 30 years… the majority of our population has oral diseases, so that means that what we’re currently doing is not working.”
Dental caries, also known as tooth decay, is the most common noncommunicable disease on the planet, according to the World Health Organization.
In the U.S., about half of adults have some form of gum disease, with that number rising to 70% for Americans who are over 65, the Centers for Disease Control and Prevention noted.
The biggest problem is that people either neglect their mouth or go to the other extreme by disinfecting and sterilizing it to such a degree that they disrupt the balance of the oral microbiome, Hoss said.
Just like our gut, the mouth contains good and bad bacteria — billions of microbes in all. Disrupt this delicate balance — by using a product that kills all the bacteria in your mouth, for example — and problems can arise, he noted.
Hoss defined it as having a balanced oral microbiome as well as the right growth and development of the mouth, which leads to correct airways, a correct bite and a balanced-looking face. A healthy mouth can increase life expectancy by up to 10 years, he noted in his book.
But if something goes wrong, resulting in an unhealthy mouth, it can impact everything about a person’s well-being, including mental health. It’s “mind-boggling” how many diseases are linked to periodontal disease, including diabetes, cardiovascular and Alzheimer’s disease, Hoss writes.
Mouth health connects to overall body health, yet dentists are still mostly trained to just fill cavities or straighten teeth, rather than prevent bigger problems, he noted.
They include using harsh oral care products that contain alcohol and other ingredients that can change the oral microbiome, which took millions of years to evolve, Hoss said.
He was especially horrified by antiseptic mouthwash, which kills 99% of everything, as advertised, and leaves behind “the baddest, toughest, roughest little microbes around — poised to recolonize that entire mouth, totally unchecked by the organisms that used to hold them at bay,” he writes in his book.
Hoss urged consumers to think of the mouth as a garden, with the many helpful oral microbes inside it as flowers and plants, and the bad bugs as weeds.
“If there was a weed growing in your garden, you wouldn’t just throw acid and weed killer all over and kill everything, the way we do it in our mouth. (But) we take antiseptic mouthwash that kills everything,” he said. “What we do in the mouth is a disaster right now.”
Some of the beneficial microbes that perish after harsh mouthwash use are designed to help the body form nitric oxide, a chemical linked to blood flow that also plays an important role in regulating endothelial function, blood pressure and insulin sensitivity, researchers previously told TODAY.
Hoss recommended the following steps:
“It’s not really complicated: Brush and floss routinely using the right oral care products. Visit your dentist regularly,” Hoss said. “Your oral health impacts every part of your life.”
