We only get two pairs of teeth in our lifetime, so you should take every possible measure to keep your pearly whites healthy. Upgrading to an electric toothbrush is an excellent first step. According to Cochrane, these devices are effective and reducing plaque and gingivitis. They may also benefit folks with mobility issues such as carpal tunnel and arthritis.

If you’re looking for an affordable, well-reviewed option to impress during your next dentist appointment, check out the AquaSonic Black Series Toothbrush, available now for $40. This kit comes with a convenient travel case and eight dupont brush heads to maintain your oral health on the go. And if you’re not in the market for a fancy new toothbrush, consider this: The Black Series holds an average customer rating of 4.6 out of five on Amazon with over 47,000 reviews.

The Black Series features a 40,000 vibrations-per-minute (VPM) motor, which AquaSonic claims can dissolve stains and improve gum health in as little as a week. You can cycle between whitening, massaging and cleaning modes depending on the areas you need to target, such as your tongue or incisors. Meanwhile, the gentle brush heads can eliminate grime without damaging your enamel.

Some folks worry about the price of going electric, and replacement heads from big-name brands aren’t cheap. For example, Oral-B charges over $20 for four refills on Amazon. On the other hand, the Black Series comes with eight brush heads. Dentists recommend switching them out every 12 to 16 weeks, so this starter kit could last you nearly two years before you need to order more replacements. Alternatively, you and your significant other can share the toothbrush by dividing the heads.

Maintaining your dental health should be easy, no matter what you eat. Usually $139, you can purchase the AquaSonic Black Series with extra heads and a travel case for $40 or 71 percent off.
