Burst Pro 2.0 Sonic Toothbrush vs Oral-B iO Series 5 Electric Toothbrush

The Oral-B iO Series 5 is the safer pick for most shoppers: its round oscillating-rotating head, visible pressure ring and app coaching are backed by the largest body of clinical evidence, and the brand's heads are sold everywhere. The Burst Pro 2.0 is the better value on hardware: a sonic brush with five modes, a smart LED display, a pressure sensor and a travel case, plus a battery that runs far longer between charges. Owners of the iO rate it slightly lower and some report gum discomfort and costly replacement heads; Burst owners like the soft tapered bristles and long battery life.

• Choose the Burst Pro 2.0 if you want a soft-bristled sonic brush with a long battery, a clear display and a travel case included.
• Choose the Oral-B iO Series 5 if you want dentist-favored oscillating-rotating cleaning with app coaching and a visible pressure ring.
