Dental hygiene is important, people. If you don’t wash your face for a while, you might sprout a few zits. Those go away in time. If you stop brushing your teeth, they might fall out. Tooth loss is forever. Use the next 21 days to develop a habit that will keep your chompers in business. If you’re lazy like me, try dental flossers, which even come in the shape of dinosaurs! Plaque is not sexy. Floss.
