What’s most surprising about Catherine Werdel’s tube squeezing toothbrush design isn’t that it took so long for someone to come up with such a simple solution, but the fact that it still hasn’t been made a reality. Well, I guess it’s not that surprising. The two largest toothbrush manufacturers here in North America, Colgate & Oral-B (Crest), both also make toothpaste. So helping consumers get every last drop out of a tube is only going to hinder their sales. Clearly a conspiracy. So until some third-party brush maker steps in to shake up the industry, you’re probably better off just taking a router to your toothbrush and cutting your own groove in it.
