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

The toothpaste includes soothing aloe vera and a gentle surfactant, which makes it generally well‑tolerated, but the presence of fragrance (limonene) and certain preservatives can cause mild irritation in highly sensitive mouths.

What is the role and benefit of sodium fluoride in this toothpaste?

Sodium fluoride provides proven cavity‑prevention by strengthening enamel and reducing acid‑driven demineralisation, making it a key active ingredient for dental health.

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

It is intended for twice‑daily brushing, and while it avoids harsh abrasives, it does contain preservatives such as sodium benzoate and potassium sorbate and a fragrance component (limonene), which are approved for cosmetic use but may be a concern for those avoiding such additives.
