Toothbrush Hygiene.

A toothbrush must be kept thoroughly clean, or it will do more harm than good. A toothbrush may become laden with germs and introduce various infections into the mouth. A toothbrush that has been used during an infectious illness should be burnt. Toothbrushes used by different people should not come in contact with each other, as by this means one mouth may become infected by another.

Keep the toothbrush in a dry, airy place. Sterilise by boiling in water once a week. Wash thoroughly after use: Discard the toothbrush as soon as it becomes soft.
