Based on its formula, is this toothpaste safe for sensitive teeth or gums?

The toothpaste is generally safe for most users, but the presence of sodium lauryl sulfate, sodium laureth sulfate, fragrance ingredients and colorants can cause irritation for people with highly sensitive gums, so those individuals may prefer an SLS-free alternative.

What is the specific role and benefit of zinc citrate in this toothpaste?

Zinc citrate acts as an antibacterial agent that helps reduce plaque formation, inhibits tartar buildup, and supports enamel remineralisation, contributing to overall oral health and fresh breath.

What is the optimal brushing frequency with this toothpaste, and does it contain any controversial ingredients?

It is recommended to brush twice daily for two minutes each, using a pea-sized amount; the formula includes surfactants such as sodium lauryl sulfate and sodium laureth sulfate, fragrance components like limonene, and colorants (CI 74160, CI 77891), which some consumers consider controversial due to potential irritation or safety concerns.
