The non-mineral phase of enamel consists of proteins and water. This phase is not mixed randomly within the mineral but surrounds the large mineral crystals which are packed tightly together. The minute spaces in between the enamel crystals account for the slight porosity of enamel. During tooth development, the first formed enamel is very poorly mineralized. It appears chalk like and is dissolved readily by acids. As the newly formed enamel matures, proteins are removed and the enamel becomes more resistant to dissolution by acids (see Appendix B.2 Enamel Proteins).
