Powder Polishing. We used the powder polisher today and it is so gross! It tastes like warm salt and mint. First we polished a penny and it was amazing to see how shiny the penny got. Then we practiced on each other. I had a hard time with the high suction. I still am nervous about using it and rinsing. I don't know why. The powder polisher is really messy, but I'm sure it will be wonderful when we have a lot of stain to remove. After polishing we practiced instrumenting. I got through the entire mouth!
