If you really look at your toothbrush under a microscope, you'll probably find millions of microorganisms living on the bristles, so in order to reduce the risk of an infection or illness, such as periodontal disease and common colds/flu, you'll definitely want to consider cleaning your toothbrush every now and then.

There are many methods of cleaning a toothbrush, most of which involve using a chemical or steam, but these aren't always the best methods. It's basically like putting chemicals right back into your mouth. So, the alternatives can include using dry heat, steam, and UV to clean your toothbrush in a proper toothbrush sanitizing product.
