Product Description:
The new clinically superior new FlossAction brushhead features vibrating yellow MicroPulse bristles with a rubberized surface which penetrate deep between teeth for a floss-like clean. As the bristles penetrate between the teeth, the pads grip the surface of the teeth to sweep away food and plaque. Patented Smart Technology with dentist-inspired feedback helps you brush your best every day. This Smart technology enables the handle to communicate to the user when to replace individual brushheads. Smart Technology features available only when used with Oral-B Triumph ProfessionalCare 9000 series toothbrush. FlossAction Brushheads fit all Oral-B ProfessionalCare/Oral-B AdvancePower Rechargeable Power Toothbrushes but do not fit Oral-B Sonic Complete or CrossAction Power Toothbrushes.

I've been ordering these for at least 4 years and I have never had a problem.
