| The toothbrush is an instrument used to clean teeth, consisting of a small brush on a handle. Toothpaste, often containing fluoride, is commonly added to a toothbrush to aid in cleaning. Toothbrushes are offered with varying textures of bristles, and come in many different sizes and forms. Most dentists recommend using a toothbrush labelled "Soft", since firmer bristled toothbrushes can damage enamel and irritate gums. Toothbrushes are often made from synthetic materials, although natural toothbrushes are also known in many parts of the world.
