While your teeth are supposed to last you a lifetime, your toothbrush isn't. Even if properly cared for, the average lifespan for a toothbrush is only 3 to 4 months. Proper toothbrushing—holding your brush with a gentle grip and brushing between the gums and teeth at the gum line to remove bacterial plaque with only a gentle scrubbing motion—is best for your dental health and your toothbrush. After use, rinse your toothbrush thoroughly and let it dry before using it again. When the bristles start to splay, distort, and/or soften, replace your toothbrush. This will generally be every 3-4 months or even sooner if your toothbrush bristles become worn. Following these easy steps will ensure your primary tool for maintaining good oral healthcare remains up for its job—maintaining your dazzling smile!
