Oral B - PRO FLEX ™

A toothbrush is an oral hygiene tool used to clean the teeth, gums, and tongue. It consists of a head of tightly clustered bristles, atop of which toothpaste can be applied, mounted on a handle which facilitates the cleaning of hard-to-reach areas of the mouth. They are available with different bristle textures, sizes, and forms. Most dentists recommend using a soft toothbrush since hard-bristled toothbrushes can damage tooth enamel and irritate the gums. Before the invention of the toothbrush, a variety of oral hygiene measures had been used. This has been verified by excavations during which tree twigs, bird feathers, animal bones and porcupine quills were recovered. (updating......)
