Alternatively the appearance of the tooth can be hidden with dental restorations (e.g., composite fillings, veneers , crowns).
In dental enamel, fluorosis causes subsurface porosity or hypomineralizations, which extend toward the dentinal-enamel junction as the condition progresses and the affected teeth become more susceptible to staining. Due to diffusion of exogenous ions (e.g., iron and copper), stains develop into the increasingly and abnormally porous enamel. [7]
A stripe of petroleum jelly can be used to prevent the spread of a liquid (retain or confine a liquid to a specific area).
