Using a Worn-Out Toothbrush
When your shoes wear down, you replace them. When your tires go bald, you buy a new set of four. So why do you keep using it when your toothbrush wears down? Another terrible habit that’s pretty common is people not changing their toothbrushes often enough. As you use a toothbrush, the bristles wear down over time, making it less effective at cleaning your teeth. That means the plaque and food between your teeth aren’t being removed as well as they should be. That’s why it’s a good idea to change your toothbrush every three months so that you can always sport that winning smile and save yourself a trip to the dentist to take care of cavities and tartar.
