Mindsip insights from this episode:

Evaluate fluoride exposure to protect children's IQ

There is a growing concern and correlation shown in recent studies between levels of fluoride exposure and decreased IQ in children.

Avoid dental floss with PFAS for safer oral care

Certain types of 'gliding' dental floss are made with PFAS, the same 'forever chemicals' found in Teflon, to make them slippery.

Debunk anti-glycerin myth to support dental health

The common belief that glycerin coats teeth and prevents remineralization is unsubstantiated misinformation that originated from a single book in 1996 and is not supported by scientific studies.

Utilize hydroxyapatite for effective tooth remineralization

Hydroxyapatite, which makes up 97% of tooth enamel, is a biocompatible alternative to fluoride for remineralizing teeth because the body already recognizes it.

Follow specific oral probiotic protocol for optimal oral health

For optimal oral health, you should first floss with prebiotic floss, then brush with prebiotic toothpaste, and finally dissolve a probiotic tablet in your mouth without rinsing.

Utilize Streptococcus salivarius M18 to combat cavity-causing bacteria

The probiotic strain Streptococcus salivarius M18 is a beneficial bacteria that specifically inhibits the growth of Strep mutans, the primary bacteria responsible for cavities.

Address gum disease to lower heart attack risk

Having gum disease, which is a dysbiosis of the mouth, can increase your risk of a heart attack and stroke by as much as 50%.

Address halitosis as a sign of systemic health issues

Halitosis, or bad breath, is often not just a local mouth problem but a symptom that can be systemically connected to dysbiosis in the gut and present with other issues like acne or bloating.

Avoid antibiotic mouthwash to maintain healthy blood pressure

Using an antibiotic mouthwash like chlorhexidine can kill beneficial oral bacteria responsible for nitric oxide production, which has been shown in studies to raise blood pressure.
