Two brands dominate the electric toothbrush market: Oral-B and Philips Sonicare. Both clean significantly better than manual brushing. But they use fundamentally different cleaning technologies.
How They Clean
Oral-B uses oscillating-rotating technology. The small, round brush head spins back and forth and pulsates against each tooth.
Sonicare uses sonic vibration at extremely high frequency (up to 62,000 strokes per minute), creating a fluid dynamic action that drives toothpaste between teeth and along the gumline.
The brush head shape is more like a traditional toothbrush.
Clinical research is mixed. Some studies show a slight edge for Oral-B in plaque removal. Both are dramatically better than manual brushing.
Brush Feel and Comfort
Oral-B's small round head means you clean one or two teeth at a time. Some find this more thorough. Others find it tedious. The oscillating motion can feel aggressive on sensitive gums.
Sonicare's elongated head covers more surface area per stroke, feeling more natural.
The vibration creates a buzzy, tingling sensation that most people find pleasant. It tends to feel gentler on sensitive gums.

Replacement Brush Head Cost
Oral-B: $6 to $10 each. A year of replacements runs $24 to $40.
Sonicare: $8 to $13 each. A year costs $32 to $52.
Over five years, this difference adds up. Third-party heads are available at lower prices for both brands.
Battery Life
Oral-B: 7 to 14 days per charge depending on model.
Sonicare: 14 days to 3 weeks per charge. Advantage for travelers.
Durability
Both brands build durable products. Sonicare handles tend to last slightly longer (4-5 years vs 3-4 for Oral-B). Neither brand has replaceable batteries. When the battery dies, you replace the handle.
The Verdict
Choose Oral-B if: You want thorough mechanical cleaning, prefer a small brush head, and do not mind more frequent charging. The Pro 1000 is the best value electric toothbrush on the market.
Choose Sonicare if: You have sensitive gums, prefer a natural brushing feel, value long battery life, or want a quieter experience. The 4100 or ProtectiveClean 6100 are the sweet spots.
Both will dramatically improve your oral hygiene. The difference between them is much smaller than the difference between either one and manual brushing. Pick the one that feels better in your mouth, and you will use it consistently.
