According to TSA guidelines, you can bring an electric toothbrush on a plane in both your carry on bags and checked bags.

One thing to note, though, is that if your electric toothbrush contains a lithium-ion battery, it is preferable if it is packed in your carry-on baggage.

Now you know that you can bring an electric toothbrush on a plane, let’s find out whether you will run into any issues with certain airlines, when flying internationally, and what, if any, difference an electric toothbrush with lithium-ion batteries makes, or if you want to travel with spare batteries.

Carry On Bags vs. Checked Baggage

Checked Baggage

Bringing your electric toothbrush in your checked baggage is fine, even if it uses a lithium-ion battery.

This is because the toothbrush’s battery is usually built into the device.

But what about if you want to travel with a spare lithium-ion battery for your electric toothbrush?

In the event that you want to travel with spare lithium-ion batteries, these should be packed in your carry on bags because are prohibited in checked baggage.

Carry On Bags

You already know that you can bring your electric toothbrush in your carry on bags and spare lithium-ion batteries should also be packed in your carry on bags, but do you have to follow any procedure like taking it out of your bag when going through airport security?

While small electronic items like laptops and tablets must be removed and placed in a tray, you will not need to remove your electric toothbrush.

You can keep it right in your bag and in its case.

By Airline

When it comes to taking an item like pepper spray on a plane, there can be a lot of variation among airlines. Thankfully, bringing an electric toothbrush isn’t nearly as contentious of an issue.

Every airline, whether that be Delta, American Airlines, Southwest, to name just a few, will have no problem with letting you bring your electric toothbrush with you, either in your carry on bags or checked luggage according to TSA guidelines.

Domestic vs. International Flights

Unlike bringing a taser on a plane, which is illegal for civilian ownership in many countries around the world, bringing your electric toothbrush on a plane will pose no issue regardless of where you are flying from and to.

Electric toothbrushes are, of course, legal to own and not considered a weapon, so whether you are flying Ryanair, EasyJet, Emirates, Qantas, or any other airline around the world, you can keep your teeth clean on the plane and at your destination.

What is the Best Electric Toothbrush for Travel?

The best electric toothbrush for traveling is the Philips Sonicare ProtectiveClean 6100.

Besides its excellent performance, what makes it so great for traveling is its 2 weeks of battery life, compact design, and included travel case.

What About Bringing Toothpaste On a Plane?

If you have a long flight and want to brush your teeth after your in-flight meal or before you go to sleep, rest assured that there is no issue bringing your toothpaste on a plane.

Just make sure that the toothpaste tube is less than 3.4 fl. oz. (100 ml), as toothpaste is considered a liquid.

If not, don’t worry, you can buy a mini-sized, travel-friendly tube of toothpaste at many stores and even at the airport if you forget to buy one before you travel.
