The full picture

NEW-TOOL FEEL WITHOUT BUYING A NEW TOOL.

A great handle cannot rescue bristles that have been flattened for months. Fresh heads keep the part that meets your teeth from quietly becoming the weakest part of the routine.

This three-pack gives Sonic a simple reset: use one, keep the next two ready, and replace the current head when the bristles show wear or around the interval recommended in your manual.

  • Three replacement brush heads
  • Made for Sonic and confirmed compatible models
  • Enough spares to stop the next change from becoming another shopping task

The tool stays familiar. The brushing surface gets its fresh start.

ElectroDentist supports your daily oral-care routine; it does not replace dental checkups, diagnosis, or treatment. For pain, persistent bleeding, swelling, sensitivity, or any ongoing concern, see a dental professional.
