What do the bristles look like? Does it have an odor?
Chances are it's probably time to toss that toothbrush.
I, along with the American Dental Association (ADA), recommend replacing your toothbrush every three months, or sooner if the bristles are frayed.
It's imperative for your oral health to do this because, no matter what type of toothbrush you use, bristles that are frayed and worn lose their effectiveness. In fact, clinical re
search shows that a new toothbrush can remove more plaque than one that is worn out.
While some toothbrushes claim to feature anti-microbial bristle protection, these bristles do not kill the bacteria that is in your mouth. Nor can they protect you against oral disease or keep you from getting sick. So, if you've been under the weather lately – even with a minor cold – it's best to change the toothbrush immediately have the illness has subsided. Doing this will keep you from possibly getting sick AGAIN.
Ultimately you are the only one who is responsible for the health of your teeth and body. I urge you to make sure that your brush is working its hardest to help keep your teeth clean and healthy.
