Yes, tooth enamel naturally wears down and thins with age due to years of chewing, grinding, and exposure to acids, a process called attrition, making teeth more sensitive, prone to chips, and appear yellower as the underlying dentin shows through. While enamel loss is permanent, good hygiene, limiting acidic foods, and regular dental visits can slow this inevitable wear and tear.

Rinsing washes away the protective fluoride, reducing its effectiveness against cavities.
