szkliwo

Szkliwo is the Polish word for enamel, referring to the hard, outer layer of a tooth. It is the hardest substance in the human body, composed primarily of hydroxyapatite, a mineral form of calcium apatite. This mineral structure gives enamel its remarkable strength and resistance to wear and tear. The outermost layer of the crown of a tooth, the enamel, is translucent and its color can range from bluish-white to yellowish depending on the individual's genetics and the thickness of the enamel.

Despite its hardness, enamel does not contain living cells and therefore cannot regenerate once it is damaged or lost. Its primary function is to protect the underlying dentin and pulp from the harsh environment of the mouth, including mechanical forces from chewing, and chemical attacks from acids produced by bacteria. Saliva plays a crucial role in maintaining enamel health through remineralization, a process where minerals from saliva are redeposited onto the enamel surface, helping to repair early stages of decay. Factors such as diet, oral hygiene, and the presence of fluoride can significantly impact enamel's integrity and susceptibility to dental problems like cavities.
