Yhis “worth every penny” toothbrush for half off right now, but you’ll want to jump on it ASAP. According to our price trackers, we haven’t seen the price this low on Amazon since this past summer’s Prime Day, so this is a very rare deal and one potentially impressive stocking stuffer.

Even after the major discount, the $100 sale price could still feel steep, but so many reviewers mention that the investment is totally worth it for improved dental health.

The toothbrush has an impressive 4.5 stars across more than 11,000 ratings, and it’s easy to see why: According to the brand, this toothbrush can remove up to 10 times more plaque than a manual toothbrush, and reviews say it “leaves you feeling dentist clean.”

“Love love love this toothbrush,” raves another reviewer. “Feels like I had a professional cleaning every time I brush. Zero cavities since I started using Sonicare about 4 years.”

The toothbrush has four modes and three intensities, so you can personalize your brushing routine to your specific needs. The included pressure sensor also lets you know when you’re brushing too hard, so you can avoid damaging your gums or teeth.
