Tooth washing is the most basic oral treatment project, and there is no technical content, mainly because the doctor washed your baby carelessly. Dental and oral clinics in general hospitals can wash teeth. The main reason for washing teeth is to choose regular medical institutions with better sanitary conditions and better disinfection. It's normal to go to the hospital to have your teeth cleaned. Tooth washing is general 100-200 yuan. If there is a group purchase online, the price is cheaper. Tooth washing also includes many items, generally including: tooth washing, tooth polishing, medicine application and sand blasting. If you buy a group, you must see the packaging clearly. Sandblasting is generally aimed at tobacco stains and tea stains. If not, there is no need for sandblasting. Yesterday, I washed my teeth in Linyi Stomatological Hospital without sandblasting. The group purchase price is 38 yuan, which feels very good.
