Oral-B Pro 500 vs Philips Sonicare 1100
Over three years, with heads at each maker's own pack price, the Philips Sonicare 1100 costs about $93 to the Oral-B Pro 500's $95. The Oral-B Pro 500 has an ADA Seal listing; none was found for the Philips Sonicare 1100. They also move differently: see the oscillating-versus-sonic explainer for what the evidence does and doesn't say about that. Every other published figure for both is in the table, with the rows where they differ tinted.

Oral-B Pro 500: what it gives up
- No pressure sensor listed; $10 more buys the Pro 1000, which has one and takes the same $5 heads
- Oral-B's page contradicts itself on the number of modes
- 2D action rather than the Pro 1000's pulsating 3D action
Philips Sonicare 1100: what it gives up
- No pressure sensor: the 3100 adds a vibrating one for $20 more and takes the same heads
- Single mode and no intensity settings; the 4100 adds two intensities for $30 more
- No travel case; the cheapest adult Sonicare with one is the $130 Series 6500
- Philips' spec lists "1 charger" without saying what kind
- No BrushSync head-change reminder, which the 4100 has
