Toothbrush
The toothbrush is an oral hygiene instrument used to clean the teeth and gums that consists of a head of tightly clustered bristles mounted on a handle, which facilitates the cleansing of hard-to-reach areas of the mouth. Toothpaste, which often contains fluoride, is commonly used in conjunction with a toothbrush to increase the effectiveness of tooth brushing. Toothbrushes are available with different bristle textures, sizes and forms. Most dentists recommend using a toothbrush labelled "soft", since hard bristled toothbrushes can damage tooth enamel and irritate the gums. Toothbrushes have usually been made from synthetic fibers since they were originally developed, although animal bristles are still sometimes used.

Famous quotes containing the word toothbrush:
“Loss of freedom seldom happens overnight. Oppression doesn’t stand on the doorstep with toothbrush moustache and swastika armband—it creeps up insidiously ... step by step, and all of a sudden the unfortunate citizen realises that it is gone.”
—Baron Lane (b. 1918)
