Changing the toothbrush frequently
Why is changing the toothbrush important?

But when that limit is crossed, it will start causing diseases and problems instead of cleaning the teeth properly. It will wear out with the passage of time and three months is the appropriate time to change it.
Since it cleans the bacteria in the mouth, bacteria start accumulating on it as well. Re-using it means we bring the bacteria get back into the mouth. That’s why people suffering from the periodontal disease should change their toothbrushes even more frequently; every four to six weeks. The bacteria in the mouth of such individuals start accumulating in the bristles and using the same tooth-brush for a longer period can be damaging. The toothbrush needs changing after a bout of illness too.

The latter needs changing and cleaning according to the instructions of the manufacturer. Different make toothbrushes has different lasting time. Many have indicators when the toothbrush is wearing off and is time to change.
