The iO Series 9 combines Oral-B's clinically proven oscillating-rotating tech with a smart pressure sensor and AI coaching app. Dentists consistently recommend Oral-B for plaque removal.
The 9500's brush head recognition auto-adjusts settings for each head type. Sonic vibration at 62,000 movements/minute reaches deeper between teeth than most competitors.
The Series 5 delivers 90% of the Series 9 experience at half the price. AI coaching, pressure detection, and 5 modes are all present — just minus the travel case and two extra modes.
The 4100 is the one dentists hand out brochures for. Simple, reliable, and at $40 it removes far more plaque than any manual brush. No app, no complexity, just results.
Quip's slim profile and AA battery (not rechargeable) make it the best electric toothbrush for frequent travelers. The subscription model ensures you change heads on schedule.
The Sonic-Fusion 2.0 is unique — simultaneously brushing and flossing saves two minutes per session. ADA-accepted water flossing combined with decent sonic action.
The Pro 1000 is the entry point to Oral-B's oscillating-rotating technology that removes 100% more plaque than manual brushing. Pressure sensor at under $50 is exceptional value.

Electric toothbrushes now come in two main designs. Oral-B uses oscillating heads, while Philips Sonicare uses sonic vibration, and both brands sell models from under $50 to well over $200. At the top, the Oral-B iO Series 9 and Sonicare DiamondClean Smart 9500 add app tracking, pressure alerts, and several brushing modes. The Oral-B iO Series 5 keeps the pressure sensor and app for about $100 at list price. Budget handles like the Sonicare 4100 and Oral-B Pro 1000 cover the basics for roughly $30 to $60, depending on the retailer and the sale.
Brush heads are the cost most buyers overlook. One 2026 roundup lists Oral-B iO heads at $9 to $12 each and Sonicare 4100 heads at $7 to $10 each. Philips lists its A3 heads for replacement every 3 months, and reviewers report that Oral-B's app sends a reminder at the same interval. That works out to about four heads a year per person. Warranties differ too: Oral-B lists 2 years on the iO Series 9 and iO Series 5, and Waterpik lists 3 years on the Sonic-Fusion 2.0. Compare handle price and head price together.
The most common mistake is paying for features you will not use. One review of the iO Series 9 concluded that similar brushing performance is available from a cheaper iO model, and that people happy with their technique are likely to stop opening the app. Another mistake is trusting battery claims: that same reviewer got roughly ten days from a charge that Oral-B rates at about two weeks. Also check head compatibility, since iO heads do not fit older Oral-B handles, and remember that a Waterpik combo is louder than a standalone brush.
Oral-B handles use oscillating heads, and Sonicare handles use sonic vibration, which one 2026 roundup describes as noticeably quieter. The same roundup says there is little real-world difference in cleaning between the two when used correctly, so choose on feel, noise, and price.
The Oral-B iO Series 9 lists seven modes, 3D Teeth Tracking, and Apple Health sync through its app. The Sonicare DiamondClean Smart 9500 lists five modes with three intensities and brush head recognition. If you will not follow app coaching, a cheaper handle is the better value.
Oral-B says the iO Series 9 and iO Series 5 signal when you brush too hard, too soft, or just right. Philips lists a pressure sensor on the DiamondClean Smart line. A sensor is most useful if you currently scrub with a manual brush.
Focused recommendations for specific needs
Oral-B says the iO Series 9 charges in about 3 hours on a magnetic charger. Roundups give the Sonicare 9500 up to 14 days per charge, and Waterpik rates the Sonic-Fusion 2.0 at up to 2 weeks between charges. Reviewers report real-world battery life can fall short of the claim.
Heads are specific to each brand and line, so a new handle can strand old heads. Budget roughly $7 to $12 per head, based on one 2026 roundup, and plan on a replacement about every 3 months. Quip sells refills by subscription, listed in that roundup at $5 every 3 months.
Check what is in the box. Oral-B lists four heads and a charging travel case with the iO Series 9, but only one head with the iO Series 5. Waterpik lists the Sonic-Fusion 2.0 with one flossing brush head and adds a water reservoir that holds 16 oz and runs about 60 seconds.
Neither is better for everyone. One 2026 roundup says cleaning performance is similar when used correctly, so the choice comes down to oscillating versus sonic, noise, app features, and price. Sonicare is described as quieter, and Oral-B tends to offer more modes at the top of its range.
It depends on whether you want the extras. Oral-B lists the Series 9 with seven modes and four heads at $249.99 on sale (list $329.99), and the Series 5 with five modes and one head at $99.99 (list $119.99). Both list a pressure sensor and the Oral-B app.
Philips lists its A3 heads for replacement every 3 months, and a BrushSync handle can remind you. Reviewers report Oral-B's app reminds you at three months. Follow the maker's guidance for your specific head.
No. The handles brush without it. The app adds real-time coverage feedback and history, which a reviewer found useful for improving technique but easy to drop once technique is settled. Skip the app features and you can buy a cheaper handle.
Roundups give the Sonicare DiamondClean Smart 9500 up to 14 days per charge, and Waterpik lists up to 2 weeks for the Sonic-Fusion 2.0. Oral-B claims about two weeks for the iO Series 9, though one reviewer measured about ten days. Results depend on how long you brush and which mode you use.
Many shoppers do well with a budget handle. A major consumer outlet picked the Sonicare 4100 as its budget choice, calling it affordable and compatible with various replacement heads. Street prices for it run around $40 to $50. Smart features are optional extras, not requirements.
Probably not. A reviewer notes iO heads are not compatible with older Oral-B models, and iO heads cost more than classic ones. Check the head name against your handle before you buy a pack.
It combines a toothbrush with a water flosser in one handle, with Brush, Floss, and Brush + Floss modes. Waterpik lists it at $179.99 with a 3-year limited warranty. A 2026 roundup notes it is louder than standalone brushes.
