What Is in Toothpaste

Toothpaste is an abrasive dentifrice: abrasives scrub, fluoride remineralises, humectants keep it workable, and flavours address odour.

Toothpaste is an abrasive dentifrice that aids in removing dental plaque and food, suppresses halitosis and delivers active ingredients, most commonly fluoride. Those four stated functions map directly onto ingredient classes, and reading a tube means identifying which class does which job.

Abrasives provide the scrubbing action. They are the component that mechanically aids in removing plaque and food film; without an abrasive the paste would deliver fluoride but not clean.

Fluoride is the active ingredient most commonly delivered. The decline of tooth decay during the 20th century has been attributed to the introduction and regular use of fluoride-containing toothpastes — a population-level attribution, not a promise about any single tube.

Humectants keep the paste from drying out in the tube, and detergents produce the foam that carries the abrasive around the mouth. Flavouring addresses the halitosis-suppression function stated for toothpaste.

Because of variations in composition and fluoride content, not all toothpastes are equally effective in maintaining oral health. Comparing tubes therefore means comparing the stated abrasive and fluoride figures — not the flavour name or a packaging claim.

The practical order of reading a tube: fluoride content first, abrasiveness second, everything else after. The two figures that determine effectiveness are the two printed in the smallest type.

  • Abrasive — aids in removing dental plaque and food
  • Fluoride — the active ingredient most commonly delivered
  • Humectant — keeps the paste workable in the tube
  • Detergent — foams and carries the abrasive
  • Flavouring — suppresses halitosis alongside cleaning
