"hard bristle toothbrush" 的定义和意义

What is a "hard bristle toothbrush"?

A hard bristle toothbrush is a dental tool with bristles that are firmer and stiffer compared to those of a regular toothbrush. It is designed to provide a more vigorous brushing action, targeting tough stains and plaque buildup. However, it is important to note that using a hard bristle toothbrush can potentially lead to gum irritation, enamel abrasion, and damage to the tooth enamel and gum tissue if not used properly. Due to the potential risks, it is generally recommended to use a toothbrush with soft or medium bristles, especially for individuals with sensitive teeth or gums. It is advisable to consult with a dentist or dental professional to determine the most suitable toothbrush for individual oral care needs.
