The layer of enamel is made up of minerals like calcium phosphate and hydroxylapatite. Low concentration of such minerals on the tooth surface leads to the formation of chalky white spots on the dental crown. This condition is known as enamel hypocalcification.
A healthy tongue is pink in color with the papillae covering the surface of the tongue. If you are suffering from a painful tongue or altered tongue color, then it is the point of concern. Visit a doctor in such condition.
Our tongue consists of numerous bumps on its dorsal surface called the papilla. Tongue papillae contain taste buds and are responsible for the sweet, salt, bitter, and umami taste that we experience while eating or drinking.
