How Often Should You Replace Your Toothbrush?

Of all of the items in our bathroom cabinet that we don’t give a second thought to, there is one that can lead to more health problems than any of the others. I am talking about, your toothbrush, of course. And, while you should replace your razor more often than you do, an old, worn toothbrush can cause many more problems than a simple case of razor burn.

It is recommended that you replace your toothbrush every 3 months, yet many people wait much longer. If your toothbrush is splayed at the edges or looks as if it has been chewed upon by an angry beaver, it could be time to replace it. Poor dental hygiene can result from a worn toothbrush among other health issues. In fact, let’s take a look at why you should change your toothbrush more often:

When To Change Your Toothbrush

Most dentists recommend changing your toothbrush every 3 months. Toothbrushes tend to wear down rather quickly with regular brushing and, as they wear down, they become much less effective at removing plaque from your teeth and gums. Another factor to consider is that germs can hide between and build up in toothbrush bristles. This is why it is even more important to replace your toothbrush after you’ve had a cold.

Fungus and bacteria can also develop in the bristles of your toothbrush and every time you brush your teeth, you are reintroducing that bacteria to your mouth which could lead to infection and gum disease. The best way to avoid the buildup of fungus and bacteria on your toothbrush is to rinse and dry it thoroughly after every use and store it in an upright position. Be sure to cover your toothbrush head when traveling to protect it and reduce the spread of germs.

Other Risks Involved With Not Replacing Your Toothbrush Often Enough

As if that wasn’t enough to get you to run out and buy a new toothbrush right away, here’s more. Other risks and issues involved with not replacing your toothbrush often enough include damage to your gums, inability to remove plaque from your teeth properly or gingivitis. Gingivitis can lead to infection, which can cause your teeth to fall out.

As you can see, it is very important to replace your toothbrush every three months with a new one.
