3. Brushing Technique:

   Guide your child to gently move the brush head across all surfaces of their teeth. The 2-minute timer will ensure adequate brushing time, with a pulse reminder every 30 seconds to encourage moving to a different quadrant of the mouth (upper right, upper left, lower right, lower left).

2. Replacing Brush Heads:

   Dentists recommend replacing brush heads every 3 months, or sooner if bristles become frayed. To replace, gently pull the old brush head off the shaft and push a new one into place.

3. Battery Replacement:

   When the toothbrush performance decreases, it's time to replace the AAA battery. Follow the battery installation steps in the "Setup" section.

4. Storage:

   Store the toothbrush upright using its suction cup base on a clean, smooth surface. Ensure the protective bristle cover is in place when not in use.
