此題核心為兒童口腔衛生指引。美國兒童牙科學會（AAPD）建議 3 歲以下兒童應使用米粒大小的含氟牙膏，以預防齲齒同時避免過量攝取導致氟斑牙。正確做法是每日兩次刷牙，並由家長協助或監督。睡前飲用含糖飲料（如果汁）會使糖分停留在牙齒表面，引發「奶瓶性齲齒」。氟化物是預防齲齒的黃金標準，適量使用安全且必要。
The American Academy of Pediatric Dentistry recommends using a rice-sized amount of fluoride toothpaste for children under three years old to prevent cavities while minimizing the risk of fluorosis from ingestion. Parents should brush twice daily and supervise to ensure proper technique and safety.
