How Oral Health Is Connected to the Immune System with My Dentist Uncle Dr. Sam Z!
On this episode of My Allergist Dad, Drew and Dr. Z are joined by Drew’s uncle, dentist Dr. Sam Zwetchkenbaum (former chief of the oral health program at the Rhode Island Department of Health), to discuss how oral health connects to allergies, asthma, and whole-body inflammation. They explore how the oral and gut microbiomes influence each other, how mouth breathing from untreated allergies can affect palate development and orthodontic needs, and how asthma and allergy medications (including inhaled steroids and drying drugs) can increase cavity risk by reducing saliva. Sam explains fluoride’s role in protecting teeth, highlights findings from Medicaid claims showing kids on asthma medications needed more restorative care and extractions, and stresses brushing, flossing, rinsing after inhalers, healthier snacks, and consistent dental checkups—especially for older adults on multiple drying medications. 00:00 Dentistry Meets Allergies 00:40 Meet Dr Sam Z 01:41 The Dr Z Name 03:20 Oral Gut Microbiome 04:08 No Brushing Experiment 06:21 Allergies Change Mouth 07:31 Palate Growth Explained 10:05 Diet And Jaw Evolution 12:29 Meds Dry Mouth Risks 14:59 Fluoride Basics Debate 16:39 How Fluoride Works 17:31 Acid Sugar And Bacteria 18:31 Baking Soda Toothpaste 19:19 Sensodyne Family Stories 20:00 Fluoride Microbiome Debate 20:24 Inflammation And Oral Health 21:39 Flossing Diabetes Connection 22:24 Dog Teeth And Whole Body 24:12 Dry Mouth Med Side Effects 26:30 Dental Chair Allergy Myths 30:55 Metals Crowns Biocompatibility 32:18 Burning Mouth Syndrome 34:54 Asthma Meds Teeth Dominoes 38:28 Snack Swaps For Cavities 40:13 System Gaps And Messaging 43:13 Final Takeaways And Disclaimer
