A whole-mouth toothbrush for those tired of doing it the old-fashioned way
It pays to be slightly skeptical of public-health advice. Sometimes, it’s merely a political expedient. British people, for example, were advised that eating extra carrots during World War II could improve their eyesight at night. It emerged later that this was part of a ruse to explain to the Nazis why Royal Air Force pilots had seemingly superhuman nighttime vision. What was actually helping Spitfire aces “see” was radar.
Other health advice has often been mistaken, oversimplified, or made up for commercial gain, whether it’s the mantra about five servings of fruit and vegetables a day (we probably need more), the idea that cholesterol is always bad for you (it’s way more complicated than that), the notion that fat makes you fat (faulty but heavily promoted by companies making low-fat products), or that we need to “hydrate” more than is probably necessary (heavily promoted by beverage companies).
