Children's Toothbrush / Children''s toothbrush

Children's Toothbrush

The children's toothbrush has a specially designed device in the handle to create bubbles by shaking. The device contains a thermometer to measure the water temperature. The liquid in the device generates a large amount of bubbles through the shaking action in brushing. Until the bubbles filled with device, this means that the brushing time is sufficient. Using this toothbrush helps children to develop a sense of temperature and good brushing habits.
