What is tooth enamel? Tooth enamel is a hard substance found in the shell of each of your teeth and is the part of the tooth thatâs visible when you look in your mouth. Enamel is considered the hardest substance in the human body. Itâs even harder than your bones; however, it can dissolve or decay when exposed to acid and a build-up of bacteria.
In other words, the substance is alkaline. Alkaline substances differ from acids in that they are not corrosive; they are much gentler. Calcium is the most prominent mineral inside the body. Most of the calcium, about two pounds worth, is found in the skeletal bones. An alkaline is good for alleviating acidity inside the body.
