If you want to take better care of your teeth, buying a Philips Sonicare 2 Series toothbrush for $30 would be a great start.

We sometimes see the Sonicare Essence available for $20 (in fact, it is right now), but for $10 more, the 2 Series includes a slimmer design, compatibility with multiple brush head styles, and a smaller charger that’s easier to pack in a suitcase.
