The toothbrush is a tool to clean teeth. The toothbrush has a small brush at the end of a handle. Toothpaste, which often contains fluoride, is commonly added to a toothbrush to help clean the teeth. Both toothpaste and toothbrushes come in many different colours. Toothpastes can also come in many different flavours. Nice toothbrushes (especially electrical) can make toothbrushing fun and help your child on the way to perfect oral health.
