How Often Should You Replace Your Toothbrush?

Your toothbrush is the foundation of good oral health. When it comes to oral health, it isn't just about a dazzling smile and fresh breath. Poor oral health can have a negative impact on physical health. Your toothbrush is an important key to good overall health so how and when you use it, and even how often you change it, really does matter.

Change Your Toothbrush Quarterly

At a minimum, you should change your toothbrush every 3 months. Keep extras on hand and make a note to open a new one on your calendar so you don't forget.

After a Cold

Germs linger on toothbrushes. Discard yours for a fresh one if you used it while you were under the weather.

Replace Worn Toothbrushes

If the bristles of your toothbrush look worn and out of shape even before 3 months have passed, go ahead and replace it early.

Rely on the Indicator

Some brands of toothbrushes have indicator bristles that alert you when it's time for a new one. Even if it looks okay, still follow the 3-month rule.

When Your Dentist Recommends It

Your dentist has a view of your teeth and brushing habits that you don't. If your dentist recommends a change, it is time to replace your toothbrush.

After Someone Else Uses It

Sharing toothbrushes sounds romantic and chummy, but it isn't ideal. Opt for a new one before you brush again and buy a few extra for the future.
