Introduction
This manual provides essential instructions for the proper use and maintenance of your Philips Sonicare Genuine ProResults Plaque Control replacement toothbrush heads (Model HX9023/64). Designed for optimal plaque removal, these snap-on brush heads are compatible with various Philips Sonicare electric toothbrush handles.

Operating Instructions
Once the brush head is attached, apply a small amount of toothpaste to the bristles. Moisten the bristles and place them against your teeth at a slight angle towards the gumline. Turn on your Philips Sonicare toothbrush and gently glide the brush head across all tooth surfaces. The sonic vibrations will clean your teeth effectively. Refer to your toothbrush handle's specific operating manual for detailed brushing techniques and modes.

Maintenance
For optimal performance and hygiene, replace your Philips Sonicare brush head every 3 months, or sooner if the bristles appear worn or frayed. The blue reminder bristles on the brush head will fade to white, indicating it's time for a replacement.
- After each use, rinse the brush head thoroughly under running water.
- Store the brush head in an upright position to allow it to air dry.

Troubleshooting
If you experience issues with your brush head, consider the following:
- Bristle Dislodgement: Avoid direct contact with products containing essential oils or coconut oil, as these can damage the brush head and cause bristles to dislodge.
- Reduced Effectiveness: If the reminder bristles have faded significantly or the brush head appears worn, replace it with a new one to ensure effective cleaning.
- Loose Fit: Ensure the brush head is pushed down firmly onto the handle's metal shaft until it clicks. If it remains loose, check for any debris obstructing the connection.
