3. Brushing Technique and Timer
Apply a small amount of toothpaste to the brush head. Place the brush head against your teeth at a slight angle towards the gumline. Move the brush slowly across each tooth surface. The toothbrush features a 2-minute smart timer to ensure the dentist-recommended brushing time. Additionally, a 30-second interval timer signals when to move to the next quadrant of your mouth, ensuring thorough cleaning of all areas.

Maintenance
1. Cleaning the Toothbrush
After each use, rinse the brush head thoroughly under running water. Wipe the toothbrush handle with a damp cloth. Do not immerse the handle in water for extended periods, although it is IPX7 waterproof for normal use.
2. Replacing Brush Heads
Dentists recommend replacing your toothbrush head every 3 months, or sooner if the bristles become frayed. Your COULAX toothbrush comes with 8 replacement brush heads, providing a supply for up to 2 years.
