Can I use my Oral-B electric toothbrush in the shower?
Yes, all Oral-B electric toothbrushes are waterproof, so it is fine to use them in the shower. However, we don’t recommend immersing your brush in water.
We know using your toothbrush in the shower saves a vital few minutes on hectic mornings. Just make sure that you completely dry the handle after use and before charging.
