The first patented toothbrush was 1857, acquired by H.N. Wadsworth in the United States. What's interesting is that mass production of these toothbrushes didn't occur for another 28 years in 1885. I guess that is because tooth brushing never really caught on until the end of the WWII. It was part of a soldier's daily routine to clean their teeth, and this was something that they brought home with them. Here are some toothbrushes that were similar to North American toothbrushes at the time.
