Toothbrush Care: Cleaning, Storing and Replacement. Toothbrushing plays an important everyday role for personal oral hygiene and effective plaque removal. Appropriate toothbrush care and maintenance are also important considerations for sound oral hygiene. The ADA recommends that consumers replace toothbrushes approximately every 3â4 months or sooner if the bristles become frayed with use.
The first bristle toothbrush, resembling the modern toothbrush, was found in China during the Tang Dynasty (619â907) and used hog bristle. The bristles were sourced from hogs living in Siberia and northern China because the colder temperatures provided firmer bristles.he first patent for a toothbrush was granted to H. N. Wadsworth in 1857 (US Patent No. 18,653) in the United States, but mass production in the United States only started in 1885. The rather advanced design had a bone handle with holes bored into it for the Siberian boar hair bristles.
