Care Tips for your Electric Toothbrush

We often get asked about the best way to look after an electric toothbrush, how to maximise the life of its new battery, how to store it correctly and what heads to use so we’ve laid out some hints and tips below. Feel free to add any you’ve thought of!


After you’ve brushed your teeth with your electric toothbrush, remove the head and rinse both the head and the exposed shaft of the toothbrush under running water. Dry the head and the toothbrush handle on a towel.

Store your toothbrush handle on its side to stop water seeping down the shaft and past the seals into the inner workings of your toothbrush.

Store the head somewhere dry where it’s not sitting in a pool of water. This will minimise the growth of mould or bacteria.

Battery Life

To maximise the lifespan of the rechargeable battery inside your toothbrush there are a few habits that will delay replacing the battery.

Wait until the battery is run down before recharging it. Your toothbrush might have an ’empty’ indicator or you might just notice that the motor is slowing down significantly.

Charge the toothbrush until it indicates the battery is full, or for 24 hours, whichever comes first. Don’t exceed the 24 hours because overcharging Ni-MH batteries can shorten their lifespan.

Don’t store the toothbrush on its charger between uses, as repeated top-ups can shorten the battery’s life.

Unplug your charger when it’s not in use to save a little electricity and maximise its operational life.

  1. I can not get the toothbrush head off. Help!

    1. It should just pull straight off if it’s an Oral-B or modern Sonicare. Try standing it head-first in water up to just beyond the joint between head and toothbrush body.

  2. Is it ok to let batteries go completely dead. We sometimes leave home for 4 months.

    1. Yes you can leave your electric toothbrush unused for an extended period. The battery will slowly self-discharge over many months but this is not a problem. Just give it a full charge before use and it will run correctly.

  3. How do I remove some rust/dirt due to very minor leak over 5 years, accumulated in the gear and offset axis transmitting the movement to the head in an Oral b Pro 5000? Spray it with WD40? Contact cleaner? Some other agent?

    1. To clean the gears wipe off as much of the old grease as you can with a cloth or cotton-buds. The re-apply some white lithium grease or silicone grease.

  4. great advice!

  5. Excellent ideas. These should extend my toothbrush life.
