Smart Toothbrushes

Smart Toothbrushes

So few as twenty years ago, the notion of a smart toothbrush hadn’t even been conceptualized, though various science fiction writers wrote about the use of sound waves to clean bodies as early as the 1900s.

However, nowadays, it is more than just a concept.


Smart toothbrushes are a reality!

Biography of a Toothbrush

Historians believe that the first known use of a toothbrushing implement was performed as early as 3,000 BCE. This device was known as a “chew stick” and the quite literal name speaks for itself. It was, as the name suggests, a stick on which the ancients would chew.

People would use fingers, chew sticks, soft fabrics, and other utensils to clean their teeth for just shy of 5,000 years before the invention of the toothbrush as we know it today. In 1938, the first invention of the toothbrush was publicized, simultaneously created by various manufacturers of household goods.

The toothbrushes of the early-to-mid 1900s, however, were still simply little more than chew sticks with a few bristles on the end. That’s how they would stay until the late 2000s and early 2010s, with the advent of the smart toothbrush.

Smart Toothbrushes

If you would have done a Google search for the phrase “smart toothbrush” in the early 2000s, you would likely have found the theoretical musings of a blogger or two talking about how to put bluetooth technology into something so small.

In 2019, that same search phrase will pull up countless pages of results for shopping and technological information on where to buy various models of smart toothbrushes.

One model in particular will cost about $300, but it comes with detailed sensors and multiple modes capable of adequately adjusting to meet your personalized teeth-cleaning plan as selected and customized in the corresponding smartphone app, a feature of engineering never before seen.

As Usual, Star Trek Did it Too

As you might expect when it comes to the brainchild series of Gene Roddenbury, Star Trek: Discovery featured advanced sonic toothbrushes in 2017. However, in one of the most interesting turns of events, Star Trek was copying real science rather than vice versa.

Smart toothbrushes had existed as early as 2016 and possibly even before then. Since the episode of Star Trek: Discovery in which these fantastical toothbrushers were unveiled debuted in 2017, we can only conclude that reality beat Star Trek to the chase for once.


What’s next? Laser-based teeth cleaning? “That’s just fantasy,” you might say. To which we could respond, “Yes, but it’s already happening.” Although laser toothbrushes haven’t had nearly the success of smart toothbrushes, who’s to say they won’t one day merge as so much other technology has?

Technology has come further between 1989 and 2019 than in the entire history of humanity. Will the discoveries of the next 30 years won’t come even faster? Be sure to check back soon for more great content.
