We loved our conversation with Dr. Jayson Chalmers, DDS so much that we’re sharing the full, never‑before‑heard interview. It goes deeper than our last episode “Dental Dilemmas” on the history of fluoridation, chemistry, dosing, safety signals, and what clinicians should actually recommend. 

** No CE credit for this bonus episode. (CE returns with our next regular episode on cold & flu.) **

 What you’ll learn:

• How fluoride prevents cavities (the hydroxyapatite → fluorapatite story) 
• Where the 2025 JAMA Pediatrics metaanalysis on fluoride exposure and children’s IQ fits (signal vs causality; exposure thresholds; study bias).  
• Practical guidance on OTC (~900 ppm) vs prescription (5000 ppm) toothpaste and counseling tips for kids and high-risk adults.  
• Community water fluoridation: historical context (Grand Rapids), outcomes, and how programs are tuned to ~0.7 mg/L today.
