This is a video from Insider detailing the process by which teeth are professionally deep cleaned. SPOILER SPOILER SPOILER: apparently not by removing them all first so the cleaner can work at a desk instead of inside your mouth. Also the video does contain some footage of some pretty dirty teeth, so it’s probably best not watched during your lunch break while you shovel Lean Cuisine in your mouth. And I’m not just saying that because that’s what I did and not my tummy doesn’t feel so good, but it doesn’t. “He didn’t have a Lean Cuisine, he had two Snickers Bars and four Reese’s Peanut Butter Cups.” Honey! “What?” I’m experimenting with a controversial new diet.
