Enamel is the hardest substance in your body, even harder than your bones. It's the protective outer covering of your teeth that shields your tooth crown from cavities and damage. While durable, enamel can be damaged by acidic foods and drinks, as well as by abrasive brushing techniques.
Enamel is made up of 96% minerals, with the remaining 4% consisting of water and organic materials. It's a very thin layer, but it's essential for healthy teeth.
Enamel can also refer to a type of paint that air-dries to a hard, glass-like shell. This type of paint is often used on metal surfaces to create a durable and long-lasting finish.
