What if the most overlooked lever for longer life sits right behind your smile? We trace a clear line from gum inflammation and tooth loss to cardiovascular risk, metabolic control, brain health, and ultimately all-cause mortality—then show how to act on it.

With oral and maxillofacial surgeon Dr. Imran Asin, we unpack the data that shifted our thinking: Lancet analyses linking tooth count to mortality, new pathology showing oral bacterial signatures inside atherosclerotic plaque, and periodontal therapy improving glycemic control. We explore hs-CRP as a practical marker for systemic inflammation and why cardiology is finally spotlighting gum disease and dental infection as risk drivers alongside smoking, dyslipidemia, and hypertension. The message is blunt: treat the mouth and you meaningfully change the body.

Function matters as much as markers. Lose molars and diets slide toward ultra-processed, soft calories that spike glucose and starve the microbiome. Keep 20+ teeth, and you maintain the ability to chew fiber-rich, nutrient-dense foods and enjoy social meals that protect mood and cognition. We dive into pediatric red flags—snoring, mouth breathing, and narrow arches—plus how breastfeeding and early orthodontic expansion support airway growth, sleep quality, and long-term health. Think of this as preventive airway engineering that starts in childhood and pays dividends for decades.

Chewing isn’t trivial; it lights up the hippocampus and supports cognitive resilience. That’s why preserving dentition and replacing missing teeth are brain-aware choices, not vanity. We close with a micro-prescription you can implement today: twice-daily brushing, daily flossing, quick cleans after meals, xylitol gum to shift the oral ecology, and timely tooth replacement to restore real chewing. Pair these with sleep, nutrition, and movement and you reduce risk on multiple fronts—from the plaque in your arteries to the circuits in your brain.
