Features Sustainably grown bamboo handle 100% recycled biodegradable packaging. Naturally anti-microbial Designed by a dentist Product DescriptionPiksters are Australia's no 1 interdental brush and are made of stronger, stiffer wire which resists buckling and bending. Interdental brushes are like mini toothbrushes that get into the tiny spaces between teeth and clean effectively right down to the gum line. Right Angle Pikster has a 90 degree tilt to the interdental brush head which offers the perfect angle for interdental gaps near the rear molars without the need to bend the wires. Piksters last longer, are better quality and offer better value (significantly less expensive per brush than many other brands). Extra durable bristles deliver superior cleaning ability by compressing on insertion and spring open on withdrawal. The slim compact handle allows the user to rotate the brush on insertion, resulting in an easy efficient cleaning action.
