Aquasonic Black Series Ultra Whitening Toothbrush ($30, originally $50)

This toothbrush seems like the perfect upgrade to anyone's oral care routine (including my own). The sonic technology promises a deep clean that gets teeth feeling seriously fresh, and the whitening mode makes your smile look brighter without being harsh. Plus, the sleek black design actually makes me want to leave it out on the counter — it looks that good.
