A method of smoothing teeth by, for instance, filling in cracks, chips and eroded areas by applying calcium and/or casein and/or phosphate and a source of OH− ions thereto. The method optionally provides that very thin layer(s) of dental cement be interlaced with other applied materials, and that the results be maintained in contact with the teeth involved by application of a composition of matter that adheres to said teeth and holds the results in place, while allowing at least some permeation of saliva therethrough. The method can optionally involve application of a backing strip or tray or the like to secure the other materials in place, but this is not a requirement where the composition of matter is sufficiently securing.
