How many times a year should the toothbrush be replaced?

An Arab media spoke to a dentist who believes that toothbrushes should be replaced every 3 months, both normal and electric.

According to Etamedonline, according to this dentist; Our recommendation is that the toothbrush should be replaced every 3 months or any time before the bristles are worn out, because the weak bristles of the toothbrush cannot be effective in cleaning the teeth and gums.

He added: “If you have a cold, buy a new toothbrush after recovery so that you don't get the same disease again, and all this applies to the head of an electric toothbrush as well.”
