Barkworthies Brushers are an organic dental chew crafted from the branches of the East Indies arrack tree. These twigs when chewed release an antibiotic which helps suppress the growth of bacteria and the formation of plaque, according to the manufacturer. The parallel bristles also act like dental floss to effectively clean between canine teeth. The chews also contain minerals including potassium, sodium, chloride, sodium bicarbonate and calcium oxides.
