Buyer's Guide: Oral Care Technology
- Sonic vs. Oscillating: Sonic brushes use sweeping high-frequency side-to-side vibrations; oscillating heads rotate back and forth around individual teeth.
- Pressure Sensors: Crucial feature that alerts you when pressing too hard against enamel to prevent gum recession.
- Water Flosser PSI: Adjustable 10 to 100 PSI controls ensure gentle operation for sensitive gums while stripping away interdental debris.
