You know the story: You go in for a dental checkup, lie back in the chair and pretend you’re on a beach in the Caribbean. The hygienist pokes around while you focus on the crash of the waves and the salty air on your skin. Then, in walks the dentist, who takes one look inside your mouth and lets out a big sigh. Beach fantasy over. “Your teeth are badly stained from the best things in life, like dark-roast coffee and delicious red wine,” he laments. “You’ve got plaque in every nook and cranny. If only you had a good electric toothbrush.” Isn't it time you stopped letting history repeat itself? You can with the AquaSonic Black Series Ultra Whitening Toothbrush — a No. 1 Amazon bestseller that’s over 30% off right now.

And if you've got one of those sensitive mouths that makes eating ice cream a struggle, the AquaSonic Black Series Toothbrush has you covered. Thanks to its four brush modes, you can set it for sensitivity, deep cleaning, gum massage and even whitening. This shopper vouches for the latter: "If you brush your teeth every day, you'll definitely notice a difference in how white your teeth are after using this for a few weeks.... My teeth are much whiter now than they were when I was using a manual brush."

The included travel case will allow you to bring it along on your next adventure. You'll also get an extra eight brush heads — no more shelling out piles of cash for replacement heads, as with other brands.

"My teeth have never felt so clean! I have used an electric toothbrush my whole life, and this is by far the best!" says a convert. "I usually buy Philips Sonicare, but I wanted something a little less expensive. I was nervous at first, but the quality of this product is incredible! Very powerful motor and plenty of replacement heads. The matte black finish looks very sleek and modern...."

With the AquaSonic Black Series Toothbrush, you’ll walk into your next dental appointment with your head held high. Instead of an exasperated sigh, your dentist will give you a smile, a thumbs-up and a gold star.
