Hammasemail
Hammasemail refers to the outermost layer of a tooth, also known as enamel. It is the hardest substance in the human body, composed primarily of hydroxyapatite crystals. This mineralized tissue is crucial for protecting the underlying dentin and pulp from mechanical damage during chewing and from chemical attacks by acids produced by oral bacteria. Enamel is acellular, meaning it does not contain living cells once formed. It is secreted by ameloblasts during tooth development. The color of enamel can range from off-white to yellowish, and its translucency can affect the overall appearance of the teeth. While incredibly strong, enamel can be demineralized by acids, leading to cavities. Saliva plays a vital role in remineralization, helping to repair early stages of enamel damage. Regular dental hygiene practices, such as brushing and flossing, along with a balanced diet low in sugar, are essential for maintaining the health and integrity of hammasemail.
