Abstract
Compositions, methods and kits are provided for altering the properties of a biological surface using particles such as, for instance, calcium based particles in combination with an agent that binds to the biological surface. Properties such as color, sheen, texture, strength, and odor of biological surfaces such as teeth and bone are alterable.
