Biofilm in general
Dental biofilm preserves enamel integrity through posteruption maturation. Newly erupted teeth are usually covered rapidly by acquired enamel pellicle (pellicle: thin protective membrane in some protozoa).
The process of demineralization and remineralization in the mouth is a constant process. The presence of fluoride within the biofilm is essential in limiting demineralization. Low calcium, low phosphate and low fluoride concentrations provide an environment for ideal remineralization.
