How Often Should You Change Your Toothbrush?

At NW Heights Dental, our practice is here to assist patients with a wide range of oral health care needs. This may include overall education on how to achieve and maintaining a healthy smile. Dr. Keri Smith of the Portland, OR area encourage patients to ask questions about their smile’s health.

How often should you change your toothbrush?

A common question that we are asked by patients is how often one’s toothbrush should be changed. Toothbrushes are meant to last several months. In fact, the American Dental Association, or the “ADA,” recommends that toothbrushes are replaced at least every three to four months. This may be sooner if the toothbrush bristles are frayed, or if you have recently had a cold, strep throat, or other condition that can be re-infected with the use of a toothbrush. By changing your toothbrush every three to four months, you can make sure that you are effectively brushing your teeth and that you are using a toothbrush that is best for your teeth and gums.

Why change toothbrushes after illnesses?

If you’ve had an illness recently such as strep throat, a cold, or the flu, you need to change your toothbrush as soon as possible. This is because the germs that contributed to the condition in the first place can reinfect the patient with the use of a toothbrush. This is also the reason why patients should never share their toothbrush with others, or use someone else’s toothbrush. A patient’s oral health is at risk if they choose to use another used toothbrush.

What type of toothbrush should I get?

The ADA recommends the use of a soft-bristled tooth brush and a fluoride toothpaste for brushing the teeth every day.
