Avoid using a bacteria-ridden toothbrush with these tips for cleaning your toothbrush.

How Often to Disinfect a Toothbrush

Disinfect your toothbrush at least once a week.

But, clean and rinse it every day, after each use.

This will help prevent buildup on the bristles and handle.

That’s why it’s best to keep your toothbrush ventilated and upright.

Using the microwave to disinfect a toothbrush is also not recommended.

The heat can actually damage the toothbrush.

Just be sure to remove the head from an electric toothbrush before soaking it.

Grab a small, clean bowl or cup.

Add antibacterial mouthwash to the bowlenough to fully immerse the head of your toothbrush.

(Overexposure to mouthwash can damage the bristles, so don’t leave it any longer.)

Rinse your toothbrush with warm water.

Then, let it completely air-dry.

(For electric toothbrushes, let the head dry completely before reassembling.)

It’s important to do this after every use toprevent moldfrom growing in the gap.

Keep pieces separate to let them dry completely.

After all the parts are dry, reassemble your electric toothbrush.

Warm, moist environments help germs thrive.

This is why you shouldn’t use a toothbrush cover or place your toothbrush in a drawer ormedicine cabinet.

Instead, air-dry your toothbrush.

If you notice discoloration or buildup or have been sick, it’s also time to replace your toothbrush.

Opinions differ on whether it’s OK to use a toothbrush after dropping it.

Some say to immediately throw a toothbrush away if it falls (anywhere).

Others recommend cleaning and disinfecting it following the instructions above.

A major factor may be where the toothbrush fell.

Per the ADA, you should not share your toothbrush since toothbrushes can harbor bacteria.

Sharing a toothbrush can result in exchanging bodily fluids, bacteria, and viruses.

This becomes especially important if one of you is sick to avoid the spread of disease.
