Oral-B iO3 vs Sonicare 7300: Which Electric Toothbrush Wins?

The Oral-B iO3 is our top pick for most people who want a proven electric toothbrush with a pressure sensor at a sensible price. If you prefer the sonic style of cleaning, the Philips Sonicare 7300 is the close runner-up and the highest-rated brush here.

We compared four brushes on price, features, Amazon ratings and the volume of owner feedback. Two are clear winners, one is a niche pick for people who also want a water flosser, and one is hard to recommend at its current price.

Quick picks

• Best overall: Oral-B iO3, the cheapest option here with by far the most owner reviews.
• Highest rated: Philips Sonicare 7300, discounted 30% and bundled with three brush heads.
• Best for flossing: Waterpik Sensonic Complete Care, a toothbrush and water flosser in one.
• Skip unless discounted further: RANVOO AirJet X5, which costs more than the Oral-B with far less track record.

Oral-B iO3: the safe bet

At about $106 with no discount shown, the Oral-B iO3 is the least expensive brush in this lineup. It has a 4.3-star rating across more than 19,000 reviews, which is a much larger pool of owner feedback than any rival here.

You get three cleaning modes, a visual pressure sensor that warns you when you press too hard, two brush heads and a travel case. Like other Oral-B brushes it uses a small round head that rotates and oscillates, which many people like for cleaning tooth by tooth.

The catch is running cost. iO brush heads only fit iO handles, and they are generally pricier than older Oral-B heads, so factor replacements in every three months or so.

Philips Sonicare 7300: the highest rated

The Philips Sonicare 7300 carries the best rating here at 4.5 stars, though from a smaller base of about 1,000 reviews. It is currently around $140, down 30% from a $199.99 list price.

It uses sonic vibration at 62,000 brush movements per minute, has a visual pressure sensor, and comes with three A3 Premium All-in-One brush heads. That extra head adds real value compared with the two included with the Oral-B.

It costs about $34 more than the Oral-B iO3, and the discount may not last. If you are already used to Sonicare's larger, sweeping brush head, it is the natural choice.

Waterpik Sensonic Complete Care: for flossing too

The Waterpik Sensonic Complete Care combines a sonic toothbrush with a water flosser, with 10 water pressure settings and Waterpik's PrecisionPulse technology. It is rated 4.3 stars from about 900 reviews.

At $199.99 it is the most expensive option, so it only makes sense if you actually want a water flosser. Buying it purely as a toothbrush is poor value, and combo units take up more counter space than a brush on a charger.

RANVOO AirJet X5: hard to justify

The RANVOO AirJet X5 sells for about $127, marked down 15% from $149.99. It promises AirJet deep cleaning, a 60-day battery and three brush heads.

The long battery claim is appealing for travelers, but the brush has the lowest rating here at 4.1 stars from just over 700 reviews, and it is sold by a third-party store rather than Amazon. For more money than the Oral-B iO3, you get a smaller brand with a thinner track record and less certainty about replacement heads down the line.

How to choose

Pick the Oral-B iO3 if you want the best balance of price, features and proven owner satisfaction. Choose the Philips Sonicare 7300 if you prefer sonic cleaning or want the extra brush head while it is discounted. Go for the Waterpik Sensonic Complete Care only if you also want to replace string floss.
