Why do older adults experience brittle teeth?

Analysis has shown that the outer coating of the teeth in elderly individuals contains a higher concentration of fluoride ions, which are commonly found in drinking water and toothpaste. Researchers noted that fluorides are intended to strengthen tooth enamel, compensating for the natural loss of minerals. However, it was discovered that with age, fluoride particles gradually replace protein structures, leading to an increase in the brittleness of the tooth's outer layer.

Researchers emphasize the need for further study of the enamel structure to better understand the processes affecting its hardness throughout a person's life.
