I tend to buy the cheaper toothbrushes. I mean, big whoop, I use Target branded toothbrushes. These include the cool green stripe on the bristles so you know when it’s time to replace your brush; However, I think the snapping of the actual brush itself should be an indication when to replace your brush. Much more noticeable. I was brushing my teeth and the damn thing just snapped on me. Luckily, they come in packs of two.
