    Abstract: A floss stick includes a horizontal stick body, first and second extension arms, at least one horizontal floss, and at least one inclined floss. The first and second extension arms extend transversely from the stick body and are spaced apart from each other. The horizontal and inclined flosses are connected between the first and second extension arms and are adapted for removing dental plaque from teeth. The inclined floss is inclined relative to the horizontal floss, and cooperates with the horizontal floss to define a gap therebetween, in which the dental plaque removed is confined by capillary action.
