What happens when you use a plastic case on your toothbrush –

You’ve probably asked yourself the question: “If I use the plastic cover, will I keep the toothbrush safe from bacteria?”. The answer is no. Even worse. “If the bristles of the brush are wet (which is normal!), the cover favors the proliferation of bacteria, fungi and viruses”, warns dentist and researcher in biomedical sciences Sandra Duvoisin, from São Bento do Sul (SC). But, for those who are in the habit of carrying the toothbrush in the toiletry bag, she says that the cover is a palliative alternative to avoid contamination by germs and dirt from the bag and the environment. One way to combat unfriendly invaders is to sanitize the cape and brush every day – in fact, there are already specific products for this on the market. Even so, change them every three months.
