Electric toothbrushes: ADA review, running costs, and battery waste
An electric toothbrush is a small appliance that you feed with brush heads for years, and its battery decides how it ends. Before comparing models, it helps to know what the American Dental Association says about whether you need one at all.
The short answer. The ADA says manual and powered toothbrushes are both effective at removing plaque, so a manual brush used well is a complete answer. It adds that people with dexterity problems, children, and people with braces may find a powered brush easier. If you buy one, look up that exact model's ADA Seal record, count a year of heads as well as the handle, and plan where the battery goes at the end. For gum problems, sensitivity or pain, ask your dentist or hygienist which kind suits you.
Handle price in the live data, where a longer bar means a cheaper handle:
Start with the brush you have
The ADA recommends brushing twice a day for two minutes with a fluoride toothpaste, and replacing a toothbrush every three to four months, or sooner if the bristles are matted or frayed (ADA on toothbrushes). That gives you the route that is not a purchase: keep using a manual brush, or keep the electric handle you already own and replace only the head.
What the ADA Seal tells you
A product earns the ADA Seal when its maker submits data from clinical or laboratory studies and the ADA's Council on Scientific Affairs reviews it against the requirements for that product type (ADA Seal). The maker brings the evidence and the ADA judges it. A brush without the Seal has not necessarily failed anything; its maker may never have applied.
Seal records are specific. The ADA has one record for the Oral-B iO Series and a separate one for Oral-B's oscillating-rotating-pulsating brushes, which names the Pro 500, Pro 1000, Genius and Smart models. The Laifen Wave has its own record. Waterpik's page says its Sonic-Fusion 2.0 is accepted by the ADA (Waterpik). The BURST product page made no claim of ADA acceptance on the day we checked (BURST). Search the exact model, since a record for one line does not cover another from the same maker.
Count the heads, as well as the handle
Handle prices on the day we checked: the Oral-B iO Series 4 at $99.99 on Oral-B's site, which takes iO heads only (Oral-B); the Philips Sonicare 4100 at $49.99 at Target; the quip Smart Rechargeable at $55 (quip); BURST at $69.99; the Laifen Wave from $79.99 (Laifen); and the Waterpik Sonic-Fusion 2.0, a brush and water flosser in one, at $179.99 or $139.99 on sale.
The ADA's three-to-four-month rule means three or four heads a year. BURST's page offers heads by subscription at $7 every 90 days, which comes to about $28 a year on top of the handle. Price a year before you buy: handle plus heads, then check whether the heads are sold anywhere besides the maker's own subscription.
The battery decides the ending
quip's Twilight Metal model runs on one AAA battery that quip says lasts up to 3 months, and costs $35 (quip). There is no charger, but you keep buying batteries. For rechargeable handles, the EPA says lithium-ion batteries and devices containing them should not go in household garbage or recycling bins, and should go to a battery recycler or household hazardous waste collection point (EPA).
Heads are waste too. SURI says its heads are made from cornstarch and castor oil and can be sent back free with a prepaid mailer; its brush costs $105, or $135 with a UV case (SURI). SURI's maker, Coral Innovations, is a Certified B Corporation with an overall score of 88.9 (B Lab).
Check the recall record
The US Consumer Product Safety Commission's recall database returned no recalls under the brand names Oral-B, Sonicare, Goby, Laifen, Waterpik or Bitvae when we searched in September 2026 (CPSC recall data). The database does catch this category: in April 2026 CPSC announced a recall of Autobrush Sonic Pro children's toothbrush boxes, which held a lithium coin battery that children could easily reach (CPSC). CPSC warns that swallowed coin batteries can cause internal chemical burns and death, so keep spare batteries and chargers away from small children.

| No charger | quip's AAA model | One AAA battery, up to 3 months by quip's figure |
| Head waste and maker accountability | SURI | Free head returns and a published B Corp score, at the highest brush-only price here |
| Brushing and flossing in one handle | Waterpik Sonic-Fusion 2.0 | ADA acceptance stated on its page, at the highest price here |
A five-minute check
- Search the exact model in the ADA's Seal product search.
- Add up a year: handle plus three or four heads.
- Search the brand on CPSC's recall site.
- Find where your area collects lithium-ion batteries before the handle dies.
What we are not telling you
We do not test cleaning, compare modes, or judge which brush suits your mouth. Prices move with sales, and head prices outside BURST were not confirmed for this page. None of this is dental advice: your dentist or hygienist knows your teeth and gums.
