Fluoride toothpaste: check the ppm, spit don’t rinse

What does the ppm on the tube mean, and should you rinse after brushing?

  1. 1Adults and children 6+: 1,350–1,500 ppm; 1,450–1,500 beats 1,000–1,250
  2. 2Under 3: a smear; 3–6: pea-size; at least 1,000 ppm
  3. 3Spit, don’t rinse — keep fluoride on the teeth
  4. 4Twice a day; the bedtime brush matters most
  5. 5Fluoride varnish at the dentist cuts new permanent-tooth decay by about 43%
  6. 6Free sugars under 10% of energy; frequency matters more than amount

Taiwan’s tap water is not fluoridated — toothpaste is the main source. Dry mouth on dialysis? Ask about high-fluoride toothpaste.
