How to Clean a Mechanical Toothbrush

The American Dental Association recommends replacing toothbrush heads every three to four months.

Not only do electric toothbrushes get dirty during use, but everyday bathroom activities such as flushing the toilet or taking a shower can also cover them with a variety of unappealing and potentially dangerous bacteria, molds and viruses. Although it’s not possible or necessary to keep your toothbrush completely sterile, cleaning it thoroughly after each use will keep germs within safe limits and make for a more pleasant brushing experience.

Things You'll Need

• Cleaning cloth
• Mild household spray cleanser (optional)
• Distilled white vinegar
• Cotton swabs

Instructions

1. Rinse your toothbrush thoroughly with tap water after brushing. Leave the brush running to aid in cleaning. Remove stubborn food particles and toothpaste clumps by hand, if necessary.

2. Turn the toothbrush off. Remove the head and rinse the shaft. Turn the tap off. Shake the shaft vigorously to remove excess water.

3. Wipe the toothbrush handle with a damp cloth. Use a mild household cleanser or distilled white vinegar, if desired.

4. Wipe the toothbrush holder clean with a cotton swab soaked in distilled white vinegar.

5. Replace the head on the handle. Place the toothbrush upright in its holder and allow it to air-dry.

Tips & Warnings

• Soaking the brush for 10 minutes in an alcohol-based mouthwash may help to reduce germs. Rinse the brush afterward and shake out the excess water.

• Keep toilet lids down when flushing. Store your toothbrush in a cabinet, if possible.

• Don’t try to sterilize your toothbrush in a dishwasher or microwave, as this is likely to damage the brush.

• Don't store your toothbrush in an airtight container. Damp, enclosed spaces encourage bacterial growth.
