Toothpaste: what actually matters in the formula
Flavour sells, fluoride works. How to read a formula without being led by the packaging.
Fluoride, the only proven active
It is the ingredient whose effect on preventing decay is best established. A fluoride-free toothpaste may clean, but it does not remineralise enamel.
The concentration is printed on the tube in ppm: the most useful information on the whole pack.
Watch the abrasiveness
Highly abrasive “whitening” formulas remove surface stains but wear enamel over time. And enamel does not regenerate.
A tooth that becomes cold-sensitive after a few weeks of use is a stop signal, not an acceptable side effect.
Flavour is not trivial
A toothpaste used for two minutes, twice a day, does more than an excellent one used for thirty seconds because you dislike the taste.
With children especially, flavour determines adherence — and adherence is what protects teeth.
