This will stop toothpaste from spraying off. 4.Divide your mouth into four quadrants/sections and brush one by one 5.Brush the outside surfaces horizontally along the gum line, slowly moving the brush heads along each tooth. 6.Brush the inner surfaces and be sure to hold the brush on each tooth for a few seconds at a time. 7.Tartar often forms more on the lower incisors. Give these teeth a little longer brushing time. 8.Brush over the chewing surfaces twice and ensure to brush the backs of you last molars DENTISTS RECOMMEND YOU REPLACE THE HEAD EVERY THREE MONTHS
