The American Dental Association says that manual and electric toothbrushes work the same—but not all experts agree. A 2019 study published in the Journal of Clinical Periodontology followed study participants for 11 years and found that those using an electric toothbrush slowed the progression of periodontal disease and retained more teeth. A 2014 review from Cochrane also found that the benefits of using electric models over manual, even for short periods of time, included less plaque and reduced likelihood of gingivitis. Luckily, there's never been a better time to make the jump. 

Electric toothbrushes are now more accessible than ever. Top oral health brands like Colgate, Oral-B, and Philips Sonicare continue to release both top-of-the-line designs alongside a collection of streamlined, more affordable options that ensure there's something for everyone. And with Prime Day 2021 officially underway, now's the perfect opportunity to score a new electric toothbrush for even less.
