Is this toothpaste safe for people with tooth sensitivity?

Yes; the inclusion of potassium citrate and zinc citrate actively reduces dentin sensitivity, and the 1450 ppm fluoride strengthens enamel, though the presence of sodium lauryl sulfate and fragrance could irritate highly sensitive mouths.

What is the role of sodium fluoride in this toothpaste?

Sodium fluoride provides cavity protection by promoting enamel remineralization and making teeth more resistant to acid attacks, with 1450 ppm being a clinically proven effective concentration.

How often should this toothpaste be used and are there any controversial ingredients?

Dentists recommend brushing twice daily with a pea-size amount; the formula contains sodium lauryl sulfate, a foaming agent that can cause irritation for some users, as well as fragrance and a synthetic color (CI 73360), which some prefer to avoid.
