What is remineralization and how does it work?
The process of tooth decay causes demineralization or loss of minerals. With the aid of fluorides, minerals can be incorporated back into the lesion through remineralization. These processes are always occurring, back and forth. It is usually not until the lesion has spread into the dentin, the second layer of tooth structure past the outermost enamel, that demineralization becomes radiographicly detectable. At the point where a lesion becomes barely detectable, scientists estimate that it has been developing for approximately 36 months.
