Can Your Toothbrush Reinfect You?When you get sick, your body develops antibodies to help fight it off. This means that once you have a specific strain of cold, your body can defend itself from the same exact invasion. So, in essence, no, you cannot get reinfected with the same illness.
Toothbrushes Harbor BacteriaYour toothbrush can house all kinds of bacteria - the flu, staph, e-coli, strep. While you cannot be reinfected with the exact same illness you just got over, that does not mean you cannot catch another strain.
If, for instance, you are suffering from a cold that just doesn't seem to give up (you have it for several weeks), you are more than likely experiencing several different strains of cold. As soon as your body learns how to fight one strain, a new one is introduced. By starting fresh with a new toothbrush, you can limit this risk.
Risk of Spreading to Others
Just because your body has learned how to fight off a specific illness, this does not mean that the immune systems of everyone else in your household can do the same. If you store your toothbrushes near to one another, while the risk is small, your germs can cross contaminate the bristles of someone else's brush. For this reason, it is best to replace everyone's toothbrushes.
Regular Replacement of ToothbrushesRegardless of being sick, you should replace your toothbrush approximately every 3 months. Unfortunately, many people tend to forget this rule. So, after being sick, replacing your toothbrush is a good way to start the process, especially if you can't remember the last time it was done.
Replacing your toothbrush right after being sick can help to prevent new illnesses, as well as spreading the illness to other family members. Contact our office to learn more.
