If your brush head falls off your toothbrush handle, ensure that the brush head is attached correctly.
- Hold the brush head with the bristles pointing in the same direction as the buttons on your toothbrush.
- Push the brush head firmly on the toothbrush until you feel a slight click.
A small gap between the brush head and the toothbrush handle is normal and necessary. The brush head must be able to move to create the right amount of vibrations.
