Clean-Cut Dad - Philips Sonicare DiamondClean ($220)
You know what they say, "healthy teeth = healthy heart." Give your dad the gift of dental health and so much more with this state-of-the-art Sonicare DiamondClean toothbrush. As the name suggests, it made our tester's teeth feel significantly cleaner after just a week of use. With several modes for whitening or for sensitive teeth, it's perfectly customizable to what dad needs. The coolest part? Instead of a charging dock, you just pop it into the glass (which you can also use to rinse) and it charges. Futuristic.
