Oral Care, simply explained
Fluoride toothpaste helps protect against cavities and strengthens enamel. It is a simple part of caring for your teeth morning and evening, with different formulas to suit your taste and dental needs.
Brushing regularly with fluoride toothpaste helps reduce tooth decay. It is a useful habit for protecting your teeth every day.
Fluoride helps the hard outer surface of your teeth resist the acids that can wear away its minerals.
Fluoride helps replace minerals in enamel at the earliest stages of decay, before a cavity has formed.
Fluoride is a mineral found naturally in water, soil and rocks. In toothpaste, it is the active ingredient that helps prevent cavities. It works at the enamel surface, the hard outer layer of your teeth, helping replace minerals lost during acid exposure and making enamel more resistant to future acid attacks.
Toothpaste supplies fluoride through compounds such as sodium fluoride, stannous fluoride or sodium monofluorophosphate. These are different forms used for the same core purpose of cavity protection. In the US, the Drug Facts panel names the active ingredient and its amount, separately from the ingredients responsible for flavor, foam and texture. That panel is the clearest way to confirm that a toothpaste contains fluoride.
On the ingredient list: Drug Facts active: Sodium Fluoride, Stannous Fluoride or Sodium Monofluorophosphate.
Choose a fluoride toothpaste suitable for your age and any advice from your dentist.
Brush for two minutes twice a day with a soft toothbrush, following the toothpaste's directions.
Spit out the toothpaste after brushing. Supervise young children and use the amount recommended for their age.
Clean between your teeth daily and keep up with dental checkups.
A simple brushing routine does the most good when the everyday basics work together.
Clean gently rather than pressing hard against your teeth and gums.
Use floss or another suitable tool to reach the spaces your toothbrush misses.
A sugar substitute you may find alongside fluoride in toothpaste.
Acids can take minerals out of enamel. Saliva and fluoride help restore the balance by supporting minerals moving back into the surface. Regular fluoride toothpaste keeps this protection part of your daily routine.
Research comparing fluoride toothpastes has found that they reduce new tooth decay compared with non-fluoride toothpaste. The practical takeaway is an easy one: choose an age-appropriate fluoride toothpaste and brush consistently.
It helps prevent cavities by strengthening enamel and supporting the replacement of minerals lost during acid exposure.
