Now that we are in a time of colds and flu, there will be many who are interested in knowing the answer to the question of whether we should change the toothbrush after having been sick. Well, if the ailment we have suffered has been infectious, it is better to replace it to prevent the germ that caused it from entering the body again, as when we use tissues over and over again. The flu virus is very comfortable among sows, as well as other viruses and bacteria that cause sore throats or toothaches.
But we should not wait to get sick or the brush to wear out to renew it. Specialists recommend replacing it every three or four months for two reasons. In the first place, the texture of the bristles degrades – they gradually weaken and bend – and this causes the brush to lose effectiveness. The second reason is that, even if we have not had the flu, this utensil is a potential source of germs. For example, if we store it in the bathroom next to other people's, there is the possibility of cross contamination.
It is very important to take all this into account because, after all, a toothbrush in optimal condition will help us, among other things, prevent cavities and future problems in our gums. Another fact that may interest you: many dental clinics advise against the use of caps or covers that protect the brush heads , since, by preventing the bristles from drying out well and keeping them in a humid environment, they contribute to the proliferation of bacteria
