While dental hygiene has ancient roots in China, the concept of preventative, routine dental care like regular cleanings is a relatively modern phenomenon, especially compared to the West.
Traditional vs. Modern Views: Traditionally, many people would only visit a doctor or dentist when a clear problem, such as a painful toothache (牙疼, yá téng), arose. The idea of going for a check-up or cleaning “just in case” was less common.
The Shift: In recent decades, particularly in urban centers, there has been a significant cultural shift. With rising incomes, greater exposure to global health standards, and a growing emphasis on personal appearance, preventative dental care has become much more popular. Young, urban professionals now increasingly view regular teeth cleanings as a normal part of their health and wellness routine.
Comparison to the West: In many Western countries, the “six-month check-up and cleaning” is a deeply ingrained part of routine healthcare from a young age. In China, while this is becoming the standard for the middle and upper classes, it's not yet a universal practice nationwide. For a learner, it's useful to know that while the procedure is the same, the cultural habit of doing it regularly is still evolving.
