How Do I Change My Oral-B Toothbrush Head?

Dental hygienists and professionals advise replacing your brush head every 90 days if you spot any worn-out bristles. This is so you can get the deepest clean possible with a new brush head that will better remove plaque.

Once you have your new brush head, you can go ahead and replace your old one. Here are the two steps to changing your Oral-B replacement brush head.

  1. Remove your worn-out brush head from the handle of your Oral-B toothbrush by lightly pulling it away from the handle.
  2. Then, slide the new brush head onto the metallic shaft of the handle. Once the new brush head is firmly attached to the handle, you'll hear a little click.

Note that it's unnecessary to twist or apply excessive force to remove or attach a brush head to the handle. The process applies to all Oral B electric brushes, brush heads, and the latest models. But if you have the iO electric toothbrush, you should replace it with an iO-compatible brush head.

Depending on the intensity of use, the bristles might become frayed in less than the expected length of usage. So it's important to regularly check your brush head and determine whether it needs to be changed sooner rather than later.

Common Brush Head Replacement Problems

Here are some common issues.

Removing A Stuck Brush Head

  • Dry the brush head and handle with a fresh towel or cloth.
  • Allow the brush to air dry by resting it in an upright position.

Toothpaste can occasionally accumulate and solidify under the brush head. And it might cause it to break during removal, leaving a portion behind.
