You know you’re supposed to change toothbrushes every three months for optimum cleaning – and more frequently if you’ve been sick to prevent re-infecting yourself. But do you ever feel guilty about throwing away all that plastic in the handle? With a GreenerStep toothbrush, you won’t feel guilty, because you keep the handle and replace only the worn-out bristles. The handles are made of polypropylene and have that grip-friendly, curvy shape that most brushes have nowadays. The bristles are nylon, and they have the angled shape recommended for cleaning, multi-level bristles, and soft bristles that are gentle on your gums. They’re BPA-free, and the handle is even dishwasher safe. At the end of three months, you pop off the old bristles, throw the handle in the dishwasher, then pop on a new set of bristles. GreenerStep offers both adult and child handles and bristles. You can select free handles for each member of your family and purchase heads for $1.99 each, or you can buy a Snap 12 Pack with two handles and 12 bristle heads for $18. With GreenerStep, you’ll save money and help the environment while making sure you have a fresh, new brush every three months.
