How to clean your toothbrush

You probably already know that brushing at least twice a day and flossing is good for your teeth. But good dental hygiene also is important for your overall health. That's because the bacteria in your mouth can enter your bloodstream and infect other parts of your body.

Gum disease, known as periodontitis, is linked to respiratory disease, rheumatoid arthritis, heart disease and problems controlling blood sugar in diabetes.

The best defense is good oral hygiene. Brushing, flossing and regular dental checkups are especially important for people with compromised immune systems. That's because they're at greater risk of infection from bacteria entering the bloodstream.

In addition to good dental habits, a clean toothbrush also helps.

How do you clean a toothbrush?

If you look online, you'll find suggestions for ways to sanitize your toothbrush. But is it necessary to sanitize it by soaking it in vinegar, putting it in the dishwasher or using an ultraviolet sanitizing device?

The short answer is no. None of the above are necessary. These "solutions" might not be effective, according to the American Dental Association. They could even damage your toothbrush.

Toothbrushes don't need to be sanitized. Instead, to keep your toothbrush clean, experts recommend that you:

1. Rinse your toothbrush under warm water before and after using it. This will help rinse away food particles and germs.
2. Store your toothbrush upright in a toothbrush holder to let it air dry between uses. Laying it in a drawer or putting it in a closed case allows mold or bacteria to grow. Use cases only while traveling.
3. Avoid letting your toothbrush touch someone else's in the toothbrush holder since bacteria can easily move between brushes. Don't share toothbrushes, either.
4. Replace your toothbrush every 3 to 4 months. Get a new one after being sick or when the bristles look frayed or worn.

Following these steps will help protect your mouth and your body.
