Two mineralized layers make up the tooth's crown. An external layer called enamel is white, strongly mineralized, and porcelain-like. Dentin, the inner layer, is the layer of bone that is less mineralized and more yellow in color. Enamel deteriorates over time, and the exterior layer may develop micro-fractures. These micro-fractures begin to accumulate pigments, stains, and debris as well as the yellow dentin support layer. Red wine, curries, coffee, habits like smoking and tooth grinding, and medications all have an impact on how much discoloration develops over time (Tetracycline). The hue of your dentin, which influences how white your teeth are, is also influenced by your genetics. The active component in bleaching (whitening) chemicals is hydrogen peroxide, sometimes known as carbamide peroxide. In order to break down the stain pigmentation, bleaching causes the peroxides to release oxygen molecules that penetrate the enamel microfractures. This oxygen release may happen gradually or suddenly. The release of oxygen is stimulated over a few hours by customized at-home bleaching procedures. Within a few minutes, oxygen is rapidly released as a result of laser whitening techniques like Zoom. A light source with high intensity is used to achieve this. Bleaching's primary adverse effect is short-term teeth sensitivity to cold. This is due to the fact that during treatment, your natural enamel pores and micro-fractures are both open. Over time, these holes and micro-fractures will re-mineralize. By increasing this remineralization process, special toothpaste can lessen sensitivity.
