just checked this page for you http://www.dentist.net/waterpik.asp
any waterpik dental stuff may be helpful. flosser clean the teeth but other
systems may clean the teeth more thoroughly than flosser and with
anti-bacterial function. Teeth is very important. Untreated gingivitis (牙龈炎
) may develop into periodontitis (牙周炎) which is terrible and almost
incurable. (i have a friend got that due to ignorance of teeth pain). Is blood
there when he brushes his teeth? Is his teeth gum darker than yours
