Remineralization occurs on a daily basis after attack by acids from food, through the presence of calcium, phosphate and fluoride found in saliva.[9][10] Saliva also acts as a natural buffer to neutralise acid, preventing demineralisation in the first place. If there is reduced saliva flow or reduced saliva quality, this will increase the risk of demineralization and create the need for treatment in order to prevent demineralisation progression.[3]
