BEST ROOT CANAL SPECIALIST IN CHENNAI! The enamel that covers our teeth is the hardest substance of the body. Yet, as strong as it is, the bacteria in our mouths can produce an acid even stronger. This can pit, etch and erode the surfaces of our teeth producing tooth caries, or more commonly, cavities. Mature enamel is acellular. That means it’s not made of cells that grow by division like the other tissues in our body. Plus, tooth enamel has a complex, interwoven structure that resembles the scales of a fish. While others have attempted to reminerali[z]e enamel, no one has been able to duplicate this unique scale-like patterning.
