How to Improve Your Teeth & Oral Microbiome for Brain & Body Health | Dr. Staci Whitman
Listen or watch on your favorite platforms
My guest is Dr. Staci Whitman, DMD, a board-certified functional dentist for kids and adults. We discuss the critical importance of oral care and the oral microbiome for brain and bodily health. We examine the negative effects of common oral care product ingredients such as alcohol, astringents, and bleaches. We also explore the history and real impact of fluoridated drinking water on oral, bone, and systemic health.
Then we discuss healthy, lesser-known solutions for bad breath, canker sores, cavities, and teeth whitening. We cover how teeth can be made to repair their own cavities and the connection between oral health and cardiovascular health, male and female fertility, dementia, and cancer.
This episode goes far beyond the best approaches to brushing and flossing and will be a valuable resource for anyone seeking to improve their oral health and appearance at any age.
