Brushing Teeth

Keep your mind sparklingly clean. As long ago as 3000 BC ancient Egyptians constructed crude toothbrushes from twigs and leaves to clean their teeth. Similarly, other cultures such as the Greeks, Romans, and Indians cleaned their teeth with twigs. Some would fray one end of the twig so that it could penetrate between the teeth more effectively. Toothbrushes are offered with varying textures of bristles, and come in many different sizes and forms. Most dentists recommend using a toothbrush labelled "Soft", since firmer bristled toothbrushes can damage tooth enamel and irritate gums as indicated by the American Dental Association.
