When it comes to electric toothbrushes, it's hard to beat the Philips Sonicare line. That's why we're excited about Amazon's Black Friday early bird discount.

For a limited time, Amazon is offering up to 50% off Philips Sonicare electric toothbrushes. As part of the sale, you can get a Sonicare Bluetooth toothbrush for just $139.95. That's a $30 discount and the best price we could find for this toothbrush.

The Sonicare toothbrush provides expert-level cleaning without much effort on your part. I especially like the HX9690 because it has a built-in pressure sensor that warns you if you brush too hard. (This is especially useful for people with sensitive teeth.) )

This Bluetooth-enabled brush can also sync with an included app to report your brushing habits. While this may not sound as exciting as a 4K TV that catches voice commands, remember that healthy teeth mean fewer trips to the dentist!
