|It is a generally accepted principle among any qualified oral health professional that the life of a toothbrush is about three months. And anyone who has ever been to a dentist or even done the slightest bit of research into dental health is most likely aware of this fact.
But why every three months? Is it some arbitrary number thrown out by the dental care industry? Is it a vast conspiracy by the toothbrush manufacturers to keep you purchasing their products four times a year? The answer to both questions is “no, it's not”. There is actually plenty of science and research behind the recommended timeframe for keeping your toothbrush. Here are just a couple of the reasons:
Bristles Become Worn and Brittle
The first and simplest reason for replacing your toothbrush after twelve weeks is the fact that it really just isn't doing its job properly after that time. The bristles are made of nylon and they aren't indestructible. They break down after a certain time and become ineffective in cleaning your teeth and gums properly.
Bacteria Builds Up
Another and more serious concern about holding on to your toothbrush for too long is the fact that no matter how well you rinse it after each use, various bacteria and particles are still left behind. If you continue to brush with the same one month after month it gets to the point where you may be introducing more of these bacteria to your mouth than you are actually getting rid of.
