Tooth enamel can erode for many reasons, often from acids lingering in the mouth and a lack of viable nutrients. If enamel wears thin, sensitivity to cold and hot temperatures can develop, followed by cavities and decay. Discoloration and yellow teeth are common attributes of thin enamel. Once enamel is gone completely and dentin is exposed, irreversible tooth loss can occur. Uncle Harry's Remineralization Kit is a natural, safe, and effective way to correct and prevent continued loss of tooth enamel. Daily use can help strengthen enamel and stabilize cavities from further demineralization. Kit includes one All Natural Tooth Powder (2 fl oz); one Miracle Mouthwash (2 fl oz); and one Liquid Remineralization for Tooth Enamel (1 fl oz).
