Young Dental offers several different prophy brush designs, including Standard, Soft White Nylon, and Midget. The Standard brushes have firm black bristles, and are available with or without a pointed brush, as screw or snap-on types. The Soft Nylon bristles are finer and more flexible, and comes as a screw type. The Midget brush has a smaller diameter and firm black bristles; like the Standard, it has a pointed brush option, but only comes as a screw type attachment.
