Detailed explanation-1: -Crown: The visible portion of the tooth, or the white part that you use to bite and chew. Enamel: The hard surface of the tooth, or the outermost layer that you clean when you brush.
Detailed explanation-2: -Enamel. Enamel covers the whole of the crown of a tooth. The enamel can be up to 2.5mm thick and is extremely hard. It is normally thinnest near the gum level and thicker on the biting surfaces of teeth.
Detailed explanation-3: -The crown is the part of the tooth that you can see above the gums. The root is the part of the tooth that is below the gums. The top layer of the crown is enamel.
Detailed explanation-4: -When a cavity begins to form, it can appear like a white spot on the tooth’s crown. This spot will appear white because the cavity has formed beneath the enamel surface of teeth, which has been eroded by acid and bacteria that eat through the surfaces of teeth. Beneath tooth enamel is the dentin structure of teeth.
