Five reasons
1. 8 heads included, not 1 or 2
Aquasonic ships with 8 DuPont brush heads, about 2.5 years of replacements. Sonicare gives you 1, Oral-B iO3 gives you 2, so you are buying refills within months on both.
2. A month between charges, not two weeks
Independent testing clocked the Aquasonic at 31 days on one charge. Sonicare 4100 is rated for 14 days, meaning roughly twice the charging trips for the same weeks of brushing.
3. The only one wearing the ADA seal
Aquasonic carries the ADA Council on Scientific Affairs seal for plaque and gingivitis reduction. Neither the Sonicare 4100 nor the Oral-B iO3 listing claims that seal here, so this is verified, not marketing copy.
4. 19x the price for teeth already clean
Oral-B iO3 lists at $379.99 against Aquasonic's $19.99. Unless a dentist has flagged gum disease needing that specific rotating head, your mouth will not notice the gap, and that is not most buyers.
5. Yes, Oral-B may edge cleaning. Skip it anyway.
A hygienist's experience says Oral-B's rotation lifts slightly more plaque than sonic vibration. But 3-year running costs put Sonicare near $150 and Oral-B near $196 in heads alone, before its $379.99 handle, while Aquasonic gets ADA-verified results for a fraction of either.
