• Clean — everyday superior plaque clean
• White — focuses on surface stains
• Gum Care — adds an extra minute of reduced-power brushing to gently massage gums

Switch modes on the handle so one brush covers daily clean, whitening and gum focus.

Brushing too hard can damage teeth and gums. ProtectiveClean emits a gentle pulsing reminder so you back off. Handy if you’re coming from a scrubbing manual technique.

Philips Sonicare sonic technology drives fluid between teeth and along the gumline while bristles break up plaque. BrushSync on the 5100 helps with brush-head replacement reminders so you don’t run a worn head for months.

• Charge on the included base
• Travel case keeps the handle and head protected
• Rinse the brush head after each use; shake dry
• Replace brush heads about every 3 months (BrushSync helps remind you)
• Safe with braces, fillings, crowns and veneers per Philips Sonicare guidance
