Introduction
This manual provides essential instructions for the proper installation, use, and maintenance of your replacement toothbrush heads designed specifically for the Sejoy JS10-1 Electric Sonic Toothbrush. Adhering to these guidelines will help ensure optimal oral hygiene and extend the lifespan of your brush heads.
Setup and Installation
Follow these steps to correctly install a new replacement brush head onto your Sejoy JS10-1 electric toothbrush handle:
- Preparation: Ensure your Sejoy JS10-1 electric toothbrush is turned off before attempting to replace the brush head.
- Removing the Old Head: Firmly grasp the base of the existing brush head and pull it straight up and off the metal shaft of the toothbrush handle. Avoid twisting, as this may damage the shaft.

- Installing the New Head: Align the new replacement brush head with the metal shaft on the toothbrush handle. Push the new head straight down onto the shaft until it clicks securely into place. A small gap between the brush head and the handle is normal.
- Verification: Gently pull on the brush head to ensure it is firmly attached and does not wobble before use.
Operating Instructions
Once the replacement brush head is securely installed, operate your Sejoy JS10-1 electric toothbrush according to its original user manual. The replacement heads are designed to deliver the same effective sonic cleaning performance.
- Wet the bristles of the brush head and apply a small, pea-sized amount of toothpaste.
- Place the brush head against your teeth at a slight angle towards the gum line.
- Turn on the toothbrush and gently guide the brush head across all surfaces of your teeth, allowing the sonic vibrations to clean effectively. Avoid scrubbing vigorously.
- Brush each quadrant of your mouth (upper right, upper left, lower right, lower left) for approximately 30 seconds, for a total recommended brushing time of 2 minutes.
Care and Maintenance
Proper care of your toothbrush heads ensures hygiene and longevity:
- Rinsing: After each use, rinse the brush head thoroughly under running water to remove any toothpaste residue and debris.
- Drying: Allow the brush head to air dry in an upright position to prevent bacterial growth.
- Cleaning Restrictions: Do not clean the brush head in a dishwasher or with harsh chemical cleaners, as this can damage the bristles and material.
- Replacement Frequency: Dentists recommend replacing your toothbrush head every 3 months, or sooner if the bristles become frayed, splayed, or worn, as worn bristles are less effective at cleaning.

Troubleshooting
- Brush head does not fit or feels loose:
- Ensure you have purchased the correct replacement heads specifically designed for the Sejoy JS10-1 model. Verify that the head is pushed down firmly onto the metal shaft until you hear or feel a click. If it still doesn't fit securely, the head might be incompatible or defective. Do not force it.
- Bristles appear worn or frayed quickly:
- This often indicates that too much pressure is being applied during brushing. Electric toothbrushes are designed to clean effectively with minimal pressure. Try to brush more gently. Also, ensure you are replacing the heads every 3 months as recommended, as bristles naturally wear over time.
