Is Cavity Fighter suitable for people with sensitive teeth or mouth irritation?

The toothpaste contains sodium lauryl sulfate, a common surfactant that can cause mild irritation for some users, so those with very sensitive mouths may prefer an SLS‑free alternative.

What role does fluoride play in Cavity Fighter's formula?

Fluoride strengthens enamel and helps remineralize early decay, making it a key active ingredient for cavity prevention in this toothpaste.

How often should Cavity Fighter be used and are there any controversial chemicals to watch for?

It is recommended to brush twice daily with a pea‑sized amount; besides fluoride, the product contains standard toothpaste ingredients such as mild abrasives, flavor agents, and sodium lauryl sulfate, which some consumers consider controversial due to potential irritation.
