Calcium and remineralisation



Teeth enamel and dentine are living tissues that are in constant remodelling. Calcium is the major components of tooth tissue and required for sound enamel and dentine structure. When
teeth are porous fluids seep beneath the surface of the teeth, and demineralisation of the enamel and dentine structure occurs, leading to caries. Remineralisation is a a process in
which minerals are returned to the molecular structure of the tooth.

Calcium needs


Bacterial flora in the mouth,especially Streptococcus mutans and Lactobacillus, use common sugars in food for their metabolism. When organic acids are produced as a result of this
metabolism the acid dissolves carbonated hydroxyapatite, the major component of enamel. This is known as demineralisation. After the sugar is gone, the mineral loss can be recovered—or
remineralised—from ions dissolved in the saliva. Cavities result when the rate of demineralisation exceeds the rate of remineralisation and the latticework is destroyed, a
process that requires many months or years.There is no connection between the bloodstream and the enamel. Thus calcium requirements for
remineralisation must be dissolved in the saliva. In neomum we use three sources of calcium to enhance the availability for mineralisation.


Fluoride is used to promote remineralization. This produces the stronger and more acid-resistant fluorapatite as opposed to the natural hydroxylapatitie..Calcium is common to
both. The fluoride replaces the hydroxide..However, recent studies in Germany have determined that the fluorapatite layer formed in this way is only 6 nanometers thick or 100
times thinner than previously believed.. The research team  question whether a layer so thin, which is quickly worn away by ordinary chewing, really could shield teeth from decay..
As it appears the role in caries prevention that fluoride plays, forming a very thin fluorapatite layer, is now dubious, ensuring adequate level of calcium for active and strong
mineralisation are available becomes the paramount concern. Neomum provides three sources of calcium for this purpose - Calcium lactate, Calcium Carbonate and Dicalcium Phosphate.
Remember, the calcium for remineralisation must be provided locally, that is through the saliva directly on the enamel surface.
