5. Maintenance
5.1 Brush Head Replacement
It is recommended to replace your brush head every 3 months, or sooner if the bristles become frayed. The SEAGO SG-2603 comes with two types of brush heads:
- 16-Degree Angled Brush Heads: Designed for deep cleaning and effective plaque removal from hard-to-reach areas.
- Soft Brush Heads: Feature high-density, soft bristles suitable for sensitive gums.
To replace, simply pull the old brush head straight off the handle and push a new one on until it clicks.


5.2 Cleaning the Toothbrush
After each use, rinse the brush head thoroughly under running water. Wipe the handle with a damp cloth. Do not immerse the handle in water for extended periods, despite its IPX7 rating, to prolong its lifespan.
5.3 Charging
Recharge the toothbrush when the battery indicator lights show low power. Use the provided USB charging cable. The toothbrush is designed for convenience, offering up to 30 days of use on a single 4-hour charge.
