Mouthwashes can Throw Your Oral Microbiome into Disarray
In 2019, a study found that reengineering the oral microbiome by using common mouthwashes and other bacteria-killing dental treatments to prevent disease doesn’t work. In other words, when you use products that can destroy your oral microbiome, which is the natural bacteria inside your mouth, you can delay the healing process and immunity your body naturally has for disease.
Just like how antibiotics can be overused, so can mouthwashes that contain bacteria-killing ingredients. There is good bacteria inside your mouth, neutral bacteria, and bad bacteria. Because mouthwashes indiscriminately remove ALL bacteria, the good and neutral bacteria are not left behind to help your mouth heal. Good bacteria supporting your oral microbiome is needed to decrease the risk of common issues like cavities, gingivitis, and bad breath.
The Ingredients in Mouthwash Are Linked to Diabetes
Some studies have linked the overuse of mouthwash to diabetes. In 2019, researchers published a study linking frequent regular use of over-the-counter mouthwash with an increased risk of developing pre-diabetes/diabetes. The study was a longitudinal study looking 1,206 overweight patients in San Juan around the age of 40-65 years. At the beginning, the patients were free from diabetes and other major cardiovascular diseases. Over the period of years, the ones that overused mouthwash were more likely to develop diabetes. Some researchers surmise this is linked to the oral microbiome.
Mouthwash Linked to More Cavities & Decrease of Saliva
According to Ask The Dentist, “contrary to popular belief, the killing of ‘99.9% of germs’ does not actually aid your dental health by preventing cavity formation.”
They explain that your oral microbiome exists to help the natural remineralization of your teeth, which is needed for natural cavity protection. If you kill ALL the bacteria inside your mouth with mouthwashes, you are not only killing the bad bacteria, but also the good and neutral bacteria you need.
In addition to killing bacteria, Ask The Dentist also claims that most mouthwashes also reduce the amount of saliva in your mouth, which is another key component to killing cavities. You need your saliva to support the remineralization process because it reorganizes the oral bacteria that cause decay while also depositing minerals like phosphorus, magnesium, and Vitamin K2 in your teeth.
Fluoride–Should It Be Used Inside Mouthwashes or Drinking Water?
The topic of fluoride is confusing and everyone seems to have a very strong opinion about it. Especially after May of 2020 when a group of 25 scientists published a meta-analysis on all the studies that have been done on fluoride thus far. The scientists stated very clearly that “fluoride is a human developmental neurotoxicant that reduces measures of intelligence in children, placing it into the same category as toxic metals (lead, methylmercury, arsenic) and polychlorinated biphenyls.”
Prior to that, in 2019, a group of 512 Canadian pregnant mothers and their children were studied and IQ tests were taken of the children at 3 to 4 years of age. The tests demonstrated that levels of fluoride present in drinking water had potentially robbed the children of 3 to 4 IQ points. These findings indicate the need to reduce fluoride intake during pregnancy.
The evidence of fluorinated drinking water stealing IQ points from American children continues to mount. However, every time a new study comes out, it seems as if the American Academy of Pediatrics (AAP) doubles down on their support of fluoride in drinking water, toothpaste, and in dental treatments as a way to safeguard children from cavities. Our advisors do not believe that fluoride in drinking water is wise. However, their opinion of fluoride in toothpaste and dental treatments is positive. This idea in general is incredibly controversial in the scientific and medical world. As explained in the video below, the AAP is trading several IQ points for essentially ONE cavity.
What the Experts on Hormone Disruption in Children Say About Mouthwashes & Fluoride
So what about mouthwashes and fluoride? It’s a totally different exposure level, so we had questions.
We reached out to Dr. Leo Trasande, Director of Environmental Pediatrics at the New York University Grossman School of Medicine, and one of our pediatric advisors. Dr. Trasande has been very active in warning parents about the problems behind hormone-disrupting chemicals. In his book, Sicker, Fatter, Poorer Trasande reveals the alarming truth about hormone-disrupting chemicals effect on our daily lives–and what we can do to protect ourselves and fight back. Because of his unique position with one foot in the medical world and one foot in the activist world, we felt he was uniquely positioned to advise us on this issue.
His response may be surprising for some of us, but it is logical and makes sense. Protecting children from the perils of cavities, which can result in the creation of other chronic diseases down the road, he supports the use of fluoride in toothpaste and dental treatments like mouthwash. However, he believes using fluoride in water is another issue that can be problematic because it’s ingested. In terms of mouthwash, you are spitting most of it out and getting very little exposure. This is where he says that fluoride has a legitimate use in toothpaste and mouthwash as a chemical that can prevent worse things down the road.
We also reached out to Dr. Bruce Lanphear, MD, MPH, who’s a Clinician Scientist and Medical Doctor at the Child & Family Research Institute, BC Children’s Hospital. He’s also a Professor in the Faculty of Health Sciences at Simon Fraser University in Vancouver, British Columbia and is well versed on the perils of fluoride and children. In fact, he was called as a witness to testify at the TSCA fluoride trial against the EPA and continues to be an expert on fluoride and exposure to children. He had a very similar take on fluoride in toothpaste as Dr. Leo Trasande and felt it was problematic in water, but not so problematic in toothpaste & mouthwash. The reasoning behind that is it’s more of a nuanced issue and the exposure levels are just nowhere as high as you would find in things like drinking water.
Bottom line: both of them seemed to think that fluoride was not as much of a problem in mouthwash as it is in drinking water.
So for the purposes of this investigation, we’ve looked at the other ingredients and clearly marked the products with fluoride for you so you can decide.
