Oral-B vs Sonicare: Which Brand Should You Buy? (2026)

Oral-B suits people who want a round head and a more advanced pressure sensor, and it costs a little more to own. Sonicare suits people who want the lowest price for a brush that still has the pressure sensor, timer and pacer. On Electric Teeth’s spec table, the two best-for-most picks land within about $8 of each other over three years, so the choice comes down to head type and feel more than total cost.

Who owns each brand

The Oral-B website says the brand has been owned by Procter & Gamble since 2005 (Oral-B’s price guide). Sonicare is listed inside Philips’ personal care range, and the Philips site carries the legal line for Koninklijke Philips N.V. (Philips’ pricing notes). Ownership tells you little about how a brush cleans, so the rest of this comparison sticks to brush-level data from Electric Teeth’s tier list.

The side-by-side table

Every figure above comes from Electric Teeth’s cost roundup, which lists the iO3 at about $69.99 and the 4100 at about $43.99. The page also states that its three-year costs assume official brush heads, so a generic head can change the total.

Where Oral-B has the edge

Electric Teeth describes the iO range as having the most advanced pressure sensor, and it names the iO3 as the cheapest model in that range. The iO3 is also the brush the review picks as its best Oral-B. Electric Teeth gives it 64 dB at its loudest test reading, which is louder than the Sonicare. Source: Oral-B’s plan breakdown.

The trade-off is the head. The review notes that iO brush heads cost almost twice as much as other Oral-B heads, and it adds that the cleaning results are not twice as good. If you want the round head but want to keep head costs down, the Oral-B Pro 1000 uses cheaper heads, and Electric Teeth puts its three-year cost at $95.

Where Sonicare has the edge

Sonicare wins on price and on the sonic feel. Electric Teeth says the 4100 offers a low and a high power setting, and that both feel less harsh on teeth and gums than the oscillating-rotating action of Oral-B models. It also reports that the 4100 has not shown a negative effect on cleaning results. The review lists the 4100 as its good-value pick with a vibrating pressure sensor, and it notes that the brush alerts you when the head needs replacing.

Electric Teeth also reports that the 4100 is quieter than the iO3, at 60 dB against 64 dB, and that the two share the same $8 head price. The gap in three-year cost, about $8, is small enough that the brush feel should decide it for most buyers. Source: Electric Teeth’s feature table.

Who each brand suits

• Pick Oral-B if you prefer a round, oscillating-rotating head, want the iO feature set, and accept higher head costs.
• Pick Sonicare if you want the lowest price for the trio of features, a quieter brush, and a sonic motor.
• Pick the Oral-B Pro 1000 if the lowest three-year cost is the main goal and you can live with a noisier brush and a shorter battery.

Before you buy

Check the replacement head price for the exact model on the brand’s own site, because head cost drives the three-year total. Some cheaper models drop one of the core features, so read the spec sheet for the exact model. Listed prices shift, so treat the figures above as a snapshot from 2026-10-14 and confirm them on the brand’s store first.

Limits of the brand comparison

This page does not report a clinical trial for either brand, and it does not say which brand removes more plaque. Electric Teeth reports results from its own disclosing tests, and this site does not run separate tests. The comparison also does not rank the two brands as companies, and it does not claim that either brand is better for every mouth. The scoring rules sit in the methodology, and the current order is on the home page.
