Is this toothpaste safe for people with sensitive gums or mouth irritation?

The product contains sodium lauryl sulfate, sodium laureth sulfate and fragrance, which can cause mild irritation in sensitive mouths; however, the fluoride and zinc citrate are generally well tolerated, so users with known sensitivities may prefer a sulfate-free alternative.

What is the role of zinc citrate in this toothpaste?

Zinc citrate provides antibacterial action that helps reduce plaque and gingivitis, supports gum health, and contributes to the whitening effect by inhibiting stains.

How should this toothpaste be used and does it contain any controversial ingredients?

Apply a pea-size amount to a soft toothbrush and brush twice daily; the formulation includes sodium lauryl sulfate, sodium laureth sulfate and titanium dioxide (CI 77891), ingredients that some consumers consider controversial due to irritation potential and nanoparticle concerns.
