What is enamel?
Enamel is the outermost layer of the tooth that protects the sensitive inside layers from decay. It is the hardest substance in the human body. Since enamel is made up of mostly minerals, it is brittle and cannot regenerate.

What can harm enamel?
Enamel can be damaged by decay and cracks. Decay occurs when enamel is in contact with the acidic plaque that forms on the surface and between teeth. Plaque is caused by bacteria feeding on the sugars and starches in food. Cracks in teeth can be caused by biting hard objects such as candy, using your teeth to open things, sports related injuries and more.

How can you protect it?
It’s easy to protect tooth enamel. Decay can be prevented by brushing your teeth after eating, especially after eating foods with a high sugar content, and by following proper oral hygiene techniques including brushing twice a day, flossing and visiting your dentist regularly. You can reduce the risk of cracking a tooth by avoiding biting hard foods or objects.
