The common practice of placing a cap on your toothbrush is actually more detrimental because bacteria favor the moist environment. Can you say reproduction sanctuary? It is said that the best way to store your toothbrush is in an upright position so that gravity can do its job, the bristles need to dry between uses. Bacteria and viruses from an infected person’s mouth can live for weeks on a toothbrush surface, continuing to cause illness. So that common cold you had a few weeks ago, is more than likely living on your toothbrush, especially if you cap it.Plot twist; even healthy and normal microorganisms can cause an infection! You are at higher risk if you have a cut or ulcer in your mouth. Crazy I know, this is probably blowing your mind right now, or maybe you already knew all of this. But if you knew all of this why didn’t you inform the world? Why are toothbrush caps still being made? Everyone can do what they please, but from now on I vow to store my toothbrush the best way. NO CAP!
