5. Operating Instructions

  • Storage: Store the brush head upright to allow it to air dry.
  • Replacement Schedule: Replace your Oral-B TriZone brush head approximately every 3 months, or sooner if the bristles become frayed or worn. The blue indicator bristles will fade halfway down to white, signaling the need for a replacement.
