PickTooth is a tool that can be used as a toothbrush. It can also be used as a toothpick, surgical knife and tooth scraper. If there is filament in your tooth, you can scrape it off. When you brush your teeth, you use the toothpick to help get food out of the gaps. If there is a part of your gum that is scraped off then you need the surgical knife to cut it. The surgical knife is also long enough to pull out and use as a knife for operation.
