The plaque scraper has two ends, use whichever ends that will remove the plaque more efficiently. Go from one side of the mouth and work around the mouth. First, work on the flat surfaces of the teeth of the cheek side. Apply the blade of the plaque scraper on the back of the flat surface. Make sure to place the tip of the plaque scraper towards the gum line, then pull the plaque scraper GENTLY, after each motion. Wipe the plaque off the blade with a tissue, then repeat until there is no more plaque on the blade. Then work between the teeth. To remove plaque between the teeth, place the blade near the gum line between teeth, then pull the blade away from the gum line. Then go on to the next tooth and finally around the mouth. Then work on the tooth surfaces of the tongue side. And repeat the scraping until the whole mouth is clean.
