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.

It's also the best electric toothbrush we tested, so you know it's legit!

Why is this a good deal? 💰

Right now, you can score what one reviewer dubbed the "Ferrari" of toothbrushes for the lowest price it's been since Prime Day. Of course, clean, well-taken-care-of teeth also mean a lower risk of cavities, which cost a pretty penny to fix — so think of this as a preemptive savings too.

Why do I need this? 🤔

If your sensitive mouth 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. It also has a built-in 30-second timer and a two-minute auto shutoff to help you develop a better brushing routine.

You also get an extra eight brush heads — each one should last you about three months, so eight should last you just over two years! No more shelling out piles of cash for replacement heads.

One of the most annoying things about using an electric toothbrush is that you have to charge it. But this one makes it easy with ultra-fast wireless charging. If you brush your teeth for two minutes, twice a day, the toothbrush can last a full four weeks on one charge. And the included travel case makes it easy to bring along on your next adventure.

What reviewers say 💬

More than 87,000 Amazon shoppers give the AquaSonic Black Series Toothbrush five stars.

Pros 👍

"I've had this toothbrush for two years now, and all I can say is it's the best toothbrush I've ever used," shared one impressed shopper. "The battery life is honestly so crazy, it lasts me like four to five months from each charge and I use it two to three times a day. After two years I've finally used all eight tips, and the fact that it has lasted me this long and I still don’t need a new one — it's mind-blowing."

"It's a great value compared to the Phillips Sonicare," wrote one convert. "The other toothbrush didn't have consistent power and would be way too intense even on the lowest setting. With this toothbrush, you can choose the strength and it's consistent. I've also noticed my teeth look much whiter and I didn't need to use whitening gel. Also love the timing function for the different zones of the mouth, I feel like I'm brushing more efficiently."

"I switched from an Oral-B series to this," wrote another happy customer. "At first I was nervous because the bristles were softer — no worries, this model gets the job done and is a sleek replacement that is travel-friendly [unlike] my other brush. My teeth feel clean to the tongue when I'm done."

Cons 👎

One user lamented that the brush heads are a little small. (That can help some users reach all the way back.) "I love the stages you can elect to have during the brushing process. The massaging selection is really nice and not seen on many of the electric toothbrushes. But I do not like the small brush heads. It makes me feel I need to brush twice as long to get good results," they said.

Some reviewers also find that the "clean" setting can feel a little rough: "Since I never really used an electric toothbrush before, the 'clean' setting was a little too harsh for my gums initially," shared one. "So I was relieved that the 'soft' setting allowed my gums to get used to the pulsation, and then I think after about three to four weeks, I was able to jump to the clean setting, which is my regular setting when I brush my teeth now."

This sleek toothbrush comes with a generous eight brush heads, so you won't have to buy replacements anytime soon.
