kiilteet

Kiilteet is a Finnish term that translates to "enamel" in English, referring to the hard, calcified tissue that covers the outer surface of teeth. This protective layer is the hardest substance in the human body and plays a crucial role in dental health. Enamel is primarily composed of hydroxyapatite, a mineral that gives it its strength and white appearance.

The formation of enamel, a process called amelogenesis, occurs during tooth development before the teeth erupt into the mouth. Specialized cells called ameloblasts are responsible for laying down the enamel matrix. Once the tooth has erupted, enamel cannot regenerate if it is damaged. Instead, it can be strengthened through remineralization, a process where minerals like calcium and phosphate from saliva are deposited back into the enamel structure.

The primary function of enamel is to protect the underlying dentin and pulp from the mechanical forces of chewing and from chemical attacks by acids produced by bacteria in the mouth. These bacteria feed on sugars and starches, producing acids that can demineralize enamel, leading to tooth decay or cavities. Maintaining good oral hygiene, including regular brushing and flossing, and a balanced diet low in sugary foods and drinks are essential for preserving the integrity of tooth enamel.
