Oral-B
Oral-B iO Series 9
A
Ranked #3 in Electric Toothbrushes
Backed by 4 cited sources
Covered by 4 outlets
The best brushing experience Oral-B makes - quiet, smooth, superbly built, with 16-zone position tracking, a colour display and an ADA seal. Excellent, but ~$200-300 buys coaching rather than meaningfully cleaner teeth, and long-term battery degradation reports temper the score.
