I have been to Dongying Stomatological Hospital opposite Xicheng Long-distance West Station. I had porcelain teeth and teeth cleaning there. Porcelain teeth are expensive, but tooth washing is relatively cheap in 60 yuan. Yellow light is not enough for tooth cleaning, so sandblasting may be needed. When you wash your teeth, you must pay attention to hygiene, especially the straw inserted in your mouth to see if it is new.
