Prime Day Deal: AquaSonic’s Black Series Whitening Toothbrush Is 40% Off
A good sonic toothbrush is one of those small upgrades you feel every morning — and AquaSonic’s Black Series has become a popular, wallet-friendly way into that category. It’s an ADA-accepted, ultra-whitening sonic brush that comes with enough replacement heads to last ages. For Prime Day, it’s 40% off.
The deal
For Prime Day — June 23–26, 2026 — the AquaSonic Black Series Whitening Toothbrush is 40% off, down to $29.95 (from $49.95). It’s a Prime Day deal, so a Prime membership is required, and the price ends when the event closes on June 26 (or earlier if it sells out).
What it is
It’s an ADA-accepted sonic toothbrush that runs at 40,000 vibrations per minute across four modes — Clean, Soft, Whiten, and Massage — with a smart timer to pace your two minutes. Per AquaSonic, it whitens while you brush and removes up to 10x more plaque than a manual brush. The reason it’s such a value buy is what’s in the box: the brush, a travel case, a charging base, and a generous set of eight brush heads, so you’re set on replacements for a long time.
How to use it
Charge it on the base, pick a mode (start with Clean, or Soft if your gums are sensitive), and let the timer run the full two minutes — the brush does the work, so you guide it gently along the gumline rather than scrubbing. Swap to a fresh head every few months; with eight in the box, that’s the easy part. The Whiten and Massage modes are there when you want a little extra.
Who it’s for
It’s for anyone moving up from a manual brush, or who wants sonic performance without a premium price — and the bundle of eight heads makes it a smart pick for a household or a gift. If you specifically want app connectivity or pressure sensors from a high-end brand, that’s a different (pricier) tier; the Black Series is the value play.
