Mindsip insights from this episode:
Limit mouthwash use to protect heart health
Chronic use of strong mouthwashes can damage nitrate-reducing bacteria on the tongue, which are crucial for producing nitric oxide for cardiovascular health.
Chew more to prevent jaw shrinkage and airway issues
We now chew for only about four minutes a day compared to our ancestors' four hours, which has led to shrinking jaws, crowded teeth, and airway issues.
Beware nicotine pouches: potential for tooth decay
Nicotine pouches marketed as sugar-free can contain sugar alcohols, and the long contact time against the teeth can lead to rampant decay.
Identify oral pathogens to combat Alzheimer's risk
Specific oral pathogens like P. gingivalis are being found in the brains of Alzheimer's patients, where they are thought to contribute to amyloid plaque formation.
Address gum disease to reduce erectile dysfunction risk
Men with gum disease are 2.85 times more likely to have erectile dysfunction, which is linked to systemic inflammation caused by oral pathogens.
Reduce fluoride exposure to protect children's IQ
A recent federal trial concluded there is a strong correlation between increased fluoride consumption and lower IQ in children, with deficits on par with lead exposure.
Spit, don't rinse, to enhance toothpaste benefits
To maximize the benefits of your toothpaste, you should spit but not rinse with water, allowing the active ingredients to remain on your teeth.
Wait 20-30 minutes to brush after eating
You should wait 20-30 minutes after eating to brush because your enamel is temporarily softened by acid, and brushing can wear it away.
Limit flour intake to protect oral health from bacteria
It's not just sugar, but also flour and other fermentable carbohydrates that feed pathogenic bacteria in your mouth, which then release the acid that causes cavities.
