Oral-B iO Series 9 Electric Toothbrush with 3 Replacement Brush Heads

A large portion of the population is afraid of the dentist, but caring for your teeth is non-negotiable. Amazon is making that task a bit easier, though, with an early Prime Day 2022 deal. Right now, the Oral-B iO Series 9 Electric Toothbrush, which senses when you're brushing too hard and if you've covered all areas of the mouth, is on sale.

Leaving oral problems untreated can have serious consequences—we all dread dealing with cavities and sensitive gums. The good news? Both are largely preventable with proper oral hygiene, which includes routine brushing.

"Aggressive brushing leads to gum damage, which is hard to recover from," Dr. Brad Eckhardt, DDS, at Elite Dental Center. The Oral-B iO Series 9 is the "perfect solution" to aggressive brushing, added Dr. Eckhardt. A red light means you're applying too much pressure, and a green light indicates just the right amount.

If you're still using a manual toothbrush, it's likely time for an upgrade. The Oral-B iO Series 9 is fully electric and equipped with technology that makes brushing gentle yet more thorough, so you don't aggravate your gums or miss any spots. "It's able to get into nooks and crannies that the traditional brush can't get into and get gums back to optimal health," said Dr. Maryam Qaiyumi, DDS, at Huntington Smiles. "I personally use this brush in my own home. I was a long-time follower of another brand, but I'll never go back! It's easy to use, interactive, and technology-forward and gives me a 'just from the dentist' type of clean."

Poor oral hygiene, such as failure to brush properly, can lead to plaque buildup, cavities, and gum disease. That's where this toothbrush comes in handy. "You don't have to use much force when brushing, especially with a toothbrush like the Oral B iO Series 9 that has the micro-vibrations fighting plaque and the oscillating brush head to wipe away bacteria," explained Dr. Jonathan Hale. "It does a lot of the dirty work for you." Less plaque typically means fewer issues.

So, who would benefit most from this Oral-B electric toothbrush? "This toothbrush was made with every smile in mind," Dr. Hale said. "Its seven smart modes can be personalized to your unique need. Whether you are looking for gum care, daily clean, teeth whitening, sensitivity-prone, or a more thorough clean with its intense mode, this toothbrush has it." Pair with the smartphone app, which tells you if you've missed any spots. The toothbrush comes with a rechargeable battery, three replacement heads, and a travel case.

Dentists aren't the only ones who praise this toothbrush. More than 2,600 shoppers have given it a perfect five-star rating on Amazon. It's been dubbed "life changing" by one reviewer and compared to the same degree of "dentist-office clean" by another user.

Loyal users to competitor toothbrush brands have even made the switch and found success. "My gums are stronger, healthier and don't bleed," wrote a former Philips Sonicare user who regularly dealt with raw, bleeding gums and noted the difference was "night and day." Gum health problems are all too common, but switching to this toothbrush can aid swollen gums, receding gum line, and other concerns. Users like the feature that notifies you if you're pressing down too hard. It's "gentle on my gums," wrote another shopper who was in search of a toothbrush to help their gums heal.

Some have even noticed visible improvements, such as "whiter teeth" and a "visible reduction in plaque," according to one user. Another shopper calls it a "must have" for a "cavity free mouth." It also receives positive feedback on the corresponding app: The "sensors work perfectly for accurate brushing," wrote a reviewer with a history of sensitive gums and periodontal disease.

Thanks to early deals for Amazon Prime Day, this Oral-B electric toothbrush is on sale for under $300. It's a pricey item, but dentists and reviewers feel it's worth it. And investing in your at-home oral hygiene routine may be a game changer to make in-office visits quicker.
