Tooth structure undergoes continuous remineralization and demineralization in the oral environment. When this balance is changed, demineralization will progress leading to a degradation of the tooth structure. Minimal intervention is the key phrase in today's dental practice. Minimal intervention dentistry focuses on the least invasive treatment options possible in order to minimize tissue loss and patient discomfort. In the last decade there has been a veritable explosion of interest in technologies which may have value for remineralization of enamel and dentine or desensitization of exposed dentine affected by dental erosion. The key element is the usage and application of remineralizing agents to tooth structure to control the demineralization/ remineralization activity. This article looks at the process of remineralization and the various agents that enhance and /or promote remineralization and discusses their clinical implications.
