A fancy toothbrush might seem like an extravagance, but it’s one of those things that could very well pay for itself by preventing a much more expensive dental problem down the line. Not only do electric toothbrushes they clean your teeth better, but they also motivate you to actually brush twice per day, if only to justify the cost.

The Philips Sonicare Flexcare is one of the best brushes in the Sonicare line, and Amazon’s marked it down to an all-time low $100 in today’s Gold Box. That gets you three different cleaning modes, three intensity settings and a pressure sensor. As an owner of the entry-level Sonicare Essence though, I’m particularly envious of the included deluxe travel case.

Just remember that this deal is only available today, so even if it seems like a lot of money, you may want to grit your teeth (not too hard!) and buy one before they sell out.
