The Dentek Easy Brush with Flexible Grip is a small plastic "stick", for lack of a betterterm with a tiny "bottle brush" attached to the end. Approximately 3" in overall lengthwith the brush portion taking up about the last half inch. Easily carried in the pocket, with a fitted plastic cap to keep it sanitary (and your pocket from getting messy) this device is utilized like dental floss for cleaning inbetween the teeth in between or in addition to regular brushing. If you have tightly spaced teeth, these are not the product for you. If you have more widely spaced teeth, gapping at the gum due to age/tooth decay/other dental issues or bridgework that has a space between it and the gumline these may be just the product for you. The advantage over floss for those of us who do have more widely spaced teeth is that you can clean ALL sides of the gap at once with the bottle brush type end.
