A clean and healthy mouth will prevent the harmful particles from entering your lungs, hence, protecting you from getting different respiratory illness as well. Hard bristle toothbrushes are an excellent in-between texture for healthy teeth cleaning. The bristles are stiff enough that they efficiently clean the teeth of plaque and built up food particles, but they aren't too hard where they can cause damage to the enamel. Hard bristle toothbrushes are also recommended by dentists because they effectively fight particles and plaque. Hard strength bristles may clean more effectively than softer ones that may push out or bend. This kind of bristle can be harsh on gums if pressure is too heavily applied when brushing.
