The interdental brush has a quadrangular shaped handle portion with an angled brush head portion with a brush head cartridge attached at one end and a removable brush head holder at the other end. The brush head can fit in a contra-angle arrangement or co-directional arrangement to the angle of the handle and the brush head support. In addition, there is a positive grip handle with a projecting thumb finger grip. The removable brush head holder into which the brush head can fit provides a smaller interdental brush and one that can be used away from home. |
