Disclosing Solution is a special type of temporary dye that sticks to the bacteria and plaque on your teeth. It turns the plaque red or blue, and shows you the spots you have missed when brushing your teeth. Disclosing Solution is non-toxic and comes in several forms: as a tablet, as a liquid, and even in a toothpaste called PlaqueHD! Dentists often like use Disclosing Solution during an appointment to help children learn to brush their teeth more thoroughly. Your dentist or orthodontist can usually give you some samples of plaque disclosing tablets, or you can buy them online.
