Hello! People eat whole grains, so it is very easy to form tartar on their teeth. In fact, after food remains in the gap between teeth, it is catalyzed by enzymes in the mouth to form tartar, which is closely combined with teeth. Tooth washing can remove these stones, but the whole process of tooth washing is a bit uncomfortable. The cost is not expensive, about 100 yuan. It is recommended to go to a regular hospital or dental clinic for scaling, so that all the teeth above and below the gums can be cleaned up. If the cleaning is not thorough, it will easily lead to gingivitis and periodontitis. I hope I can help you.
