Định Nghĩa và Ý Nghĩa của "tartar"

What is "tartar"?

Tartar is a hard and crusty buildup that forms on teeth when plaque, a sticky layer of bacteria, is not removed and hardens over time. It can lead to tooth damage and gum disease if not cleaned by a dentist. Regular brushing, flossing, and professional dental cleanings help prevent tartar buildup and maintain oral health.
