回答: 請問牙齒特別容易結牙垢是不是因為身體少什麽元素呢？ 由 一杯綠茶 於 2006-03-28 18:58:10 Show your hygienist or dentist how you brush and floss your teeth and there might be some good suggestions from them then...
Also, factors include what you eat, how often you eat, tooth crowding, failing restoratives, cavities, etc. So, talk to a dental pro first since everyone is different.
Take care. |
