Skeptics pointed to a 1969 two-year study that found no tangible benefit to electric toothbrushes (although the study did note that kids found them more fun and people with disabilities found them easier to use). In the early 2000s, when the ‘toothbrush wars’ started, the evidence was rather unconvincing. So then, what does the science say? Electrical toothbrush science The science-marketing avenue is not a one-way street: science gets brought into marketing, but sometimes, marketing also sneaks its way into science.
Just think of the cigarette advertorials from decades ago, they even featured doctors who said cigarettes make you healthier - even as the science was showing the opposite. But making something more popular and more marketable doesn’t always mean it works.
