For optimal cleaning with your Oral-B TriZone brush head:
- Wet the bristles and apply a small amount of toothpaste.
- Place the brush head against your teeth at a slight angle towards the gumline.

- 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.
