It’s important to take care of your electric toothbrush to make sure you get your best clean with every brush. Here are some tips on how to clean and take care of your electric toothbrush to keep your smile at its healthiest.

How to Clean Your Electric Toothbrush

Because one of the main purposes of a toothbrush is to remove bacteria from your mouth, it’s important to keep your toothbrush sanitary and free of bacteria.

Keep these tips in mind to keep your electric toothbrush clean and safe:

  • Keep it covered on the road, but not at home. When you travel, put your toothbrush in a travel toothbrush holder-don’t let it roll around uncovered in your suitcase or toiletry bag where it can pick up dust, dirt, and bacteria. But don’t store a toothbrush in a toothbrush holder at home-the chronically moist environment can promote bacteria growth. If you must use a covered toothbrush holder frequently, look for one with small holes to let air in. When at home, store your toothbrush upright in a cup or a toothbrush holder that allows it to air dry and has several openings to keep multiple toothbrushes separate.
  • Consider a sanitizer. There are commercially available "toothbrush sanitizers," but there’s no solid evidence to suggest that they actually keep toothbrushes cleaner than simply rinsing them with water after use and allowing them to dry. If you want to try a sanitizer, look for one that has been approved by the Food and Drug Administration for "reducing bacterial contamination that occurs naturally on toothbrushes." Be suspicious of sanitizing products that make unrealistic claims. And never try to clean your toothbrush by putting it in the dishwasher or microwave; the high temperatures can damage the brush.
  • Change your toothbrush or toothbrush head every three months

Electric Toothbrush Storage and Maintenance

In addition to the tips above, you should rinse your electric toothbrush every day with tap water after use to remove toothpaste and debris.

  • Don’t over-brush. Putting too much pressure on your toothbrush can cause the bristles to wear out more quickly and be less effective when cleaning. Brushing with an Oral-B iO electric toothbrush can help prevent overbrushing with the Smart Pressure Sensor. It turns red to signal when you’re brushing too hard and green when brushing is just right—directly on the handle.
  • Store your toothbrush in an upright position to let it air-dry.

Oral-B® Electric Toothbrush Tips

Replace your Oral-B® Electric Toothbrush brush head every three months, or when the blue Indicator® bristles fade halfway to white, or earlier if you notice fraying. Simply pull the old brush head off your handle at a straight angle, and snap on a new brush head in the same manner.

  • If this is your first time using the product, you should fully charge the battery before using, which can take up to 16 hours.
  • Once your handle is fully charged, continue using your electric toothbrush until no charge is left. Then, fully charge it again instead of charging between each use. This will help your battery perform at its best longer.
  • If you have a SmartGuide™ display with your electric toothbrush, it will need two AA batteries for power.
