Is Smiling Shark Fluoride Free Toothpaste suitable for people with sensitive teeth or gums?

Yes, its fluoride‑free, low‑abrasive formula with hydrated silica and a modest amount of sodium bicarbonate is designed to be gentle on enamel and gums, but individuals with extreme sensitivity may still experience mild irritation from the silica or surfactant, so a patch test or dentist consultation is advised.

What is the role of hydrated silica in this toothpaste?

Hydrated silica acts as a gentle abrasive that polishes and cleans tooth surfaces while also helping to thicken the paste, providing effective plaque removal without the harshness of stronger abrasives.

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

The toothpaste is intended for twice‑daily use, typically after breakfast and before bedtime; it does not contain fluoride, and while it includes common cosmetic additives such as lauryl glucoside, tetrasodium pyrophosphate, and various sweeteners, these ingredients are generally recognized as safe in oral care, though consumers sensitive to surfactants may wish to monitor their reaction.
