sodium fluoride + potassium nitrate + isopentane

This is an experimental dental formulation combining sodium fluoride (1.1% or 1450 ppm), potassium nitrate (5%), and isopentane (2%). Sodium fluoride works by making teeth stronger and more resistant to decay caused by acid and bacteria. Potassium nitrate works by calming the nerves in the teeth to reduce sensitivity. Isopentane is being investigated as an excipient in dental formulations, though research indicates it neither positively nor negatively affects fluoride efficacy in experimental models.
