How to Sanitize an Electric Toothbrush

Sanitizing a toothbrush helps to maintain cleanliness and good hygiene. This is especially important if a family member is sick or recently recovered from an illness. Microbes can grow on the bristles and the handle of the toothbrush quite easily. Not all of these microbes are dangerous, but some can be harmful and cause sickness.
