Episode notes
Prefer Topical Fluoride Toothpaste
- Use topical sodium fluoride toothpaste rather than relying on systemic water fluoridation for dental protection.
- Don’t swallow toothpaste; topical exposure during remineralization forms protective fluoroapatite on enamel.
Nutrients Determine Fluoride Effectiveness
- Fluoride toothpaste alone won’t guarantee cavity reduction if people are deficient in fat‑soluble vitamins and minerals.
- Matt suspects vitamin K2, vitamin D, phosphorus, and overall nutrient status modulate fluoride’s effectiveness.
Antioxidants Reduce Enzymatic Tooth Breakdown
- Antioxidants can limit activation of matrix metalloproteinase (MMP) enzymes during dentin breakdown and inflammation.
- Vitamins C and E, melatonin, and zinc carnosine reduce enzymatic tissue damage during early tooth decay.
