Your toothbrush doesn’t last forever, even though we all wish it would. It should be changed every three to four months to keep giving your mouth the best clean possible. Even if you forget the three to four-month rule, there are other signs that might indicate that it’s time for a change.

Here Are Some Signs That You Should Look Out For:

The Bristles Are Worn

If your toothbrush’s bristles lost their color, look worn down, point in different directions, or are falling out, it’s time to replace it.

You’ve Dropped It

If you dropped your toothbrush anywhere, play it safe and throw it out. It can pick up bacteria in less than two seconds and that’s bacteria you don’t want in your mouth.

It Has Been Kept in a Closed Container for Multiple Days

When your toothbrush is kept in a closed container it doesn’t get the opportunity to dry properly. Even if it’s the slightest bit damp, bacteria can grow easily. So, if you keep your toothbrush in a closed container without letting it dry for many days, play it safe and throw it away.

When you’re traveling, make sure your toothbrush is as dry as possible and try to limit how long you keep your toothbrush in a closed traveling container.

The Bristles Are Hard

Because of the material toothbrush bristles are made of, they tend to become hard with use. If your toothbrush’s bristles are hard then they can harm your gums or wear out your teeth’s enamel.

Someone Else Used Your Brush

If someone used your toothbrush, simply put: throw it out. This will help you avoid any cross infections that can lead to gum disease.

These are some common signs that you should watch out for when brushing your teeth. After all, the three to four-month rule doesn’t always apply to everyone since not every mouth is the same. While you should keep that rule in mind, don’t ignore the signs your toothbrush may need a change!
