Dental color tablets are a take-home kit containing a harmless colored dye that is attracted to plaque on your teeth. You can either purchase these in the dental care isle when shopping or ask your dentist if they have a sample tablet. When you chew the tablet and swish it around your mouth properly, you will be able to see the areas on your teeth that have plaque that could use extra attention when brushing and flossing. These tablets are especially helpful and fun for children and teenagers to use on a daily or weekly basis.
