Can You Bring an Electric Toothbrush on a Plane? [What You Need to Know]

Can you bring electric toothbrush on plane without a hassle? Absolutely—but only if you follow the right guidelines. The Transportation Security Administration (TSA) allows electric toothbrushes in both carry-on luggage and checked bags. However, if your toothbrush uses lithium-ion batteries or lithium metal batteries—common in many portable electronic devices—it must go in your carry-on bag, not checked baggage, due to fire risk.

Understanding these simple carry-on baggage rules helps ensure your trip goes smoothly. This guide covers everything you need to know to pack smart and travel stress-free.

Key Takeaways

• Electric toothbrushes are allowed on planes in both carry-on and checked luggage, but those with lithium-ion batteries must be in carry-on due to fire risks.

• Using alkaline batteries in electric toothbrushes provides flexibility, as these can be packed in either luggage type without restrictions.

• Before international travel, confirm the specific regulations of your destination country regarding electric toothbrushes and their batteries to avoid complications.

TSA Regulations for Electric Toothbrushes

When it comes to air travel, the Transportation Security Administration (TSA) provides clear guidelines regarding electric toothbrushes. The good news? They are not classified as restricted items and are allowed in both carry-on and checked luggage on domestic flights and international routes.

Most portable electronic devices, including electric toothbrushes with built-in batteries, can stay in your carry-on bag during security screening—no need to remove them like you would a laptop. This makes your carry-on baggage organization easier and ensures your oral care routine stays on track during travel.

However, pay close attention to the battery type inside your toothbrush:

• Electric toothbrushes with lithium-ion batteries must be packed in carry-on luggage, never in checked bags, due to fire safety regulations.

• Alkaline batteries (like AA or AAA) are safer to transport and can go in either carry-on or checked bags.

• Spare lithium batteries must always be packed in your carry-on, and each must be individually protected—for example, stored in original packaging or plastic bags to prevent contact with metal objects or battery terminals.

While spillable batteries are not common in toothbrushes, they are subject to stricter rules and should be avoided unless clearly labeled as safe for air transport. For devices with advanced features like cleaning modes, replaceable heads, or sonic technology, the key is still safe battery handling and secure packing.

Traveling with a charging station or bringing extra batteries? Keep them organized, protected, and easily accessible for inspection.

Not sure what kind of battery your toothbrush uses—or what that means for your flight? Let’s break it down in the next section.

Battery Types and Safety Requirements: What Every Traveler Must Know

Knowing the different battery types and their safety requirements is vital when traveling with an electric toothbrush. The TSA has specific regulations for various batteries to ensure passenger safety.

Here are the details for lithium-ion batteries, alkaline batteries, and nickel metal hydride batteries, and their guidelines regarding lithium content.

Lithium-Ion Batteries

Lithium-ion batteries are widely used in various portable electronic devices. This includes items such as electric toothbrushes. According to TSA guidelines, these lithium batteries must be placed in carry-on luggage due to the potential fire risk if not managed properly. Therefore, electric toothbrushes with lithium-ion batteries should always be packed in your carry-on bag.

If TSA agents ask about lithium batteries, follow these steps:

• Clearly communicate their inclusion in your luggage.

• Make sure the batteries are in good condition.

• Report any damaged batteries to airline personnel for safe disposal.

Most electric toothbrush batteries fall below TSA watt-hour restrictions, but travelers with high-capacity models should verify watt-hour ratings before departure.

Alkaline Batteries

Electric toothbrushes that use replaceable alkaline batteries, like AA or AAA, offer maximum flexibility for travelers. These batteries can be included in both carry-on and checked luggage without special fire risk considerations. This makes them an ideal choice for those who prefer the convenience of packing their toothbrush in their checked bags.

When traveling with spare batteries for alkaline-powered models, carry them in their original packaging to prevent short circuits. This keeps the batteries protected and easy to identify during security checks.

Nickel Metal Hydride Batteries

Nickel metal hydride (NiMH) rechargeable batteries are classified as “dry batteries” by TSA standards, allowing them to be packed in both carry-on and checked luggage without restrictions. These batteries are common in mid-range electric toothbrush models and provide a reliable option for travelers.

International Travel Considerations for Electric Toothbrushes

When traveling abroad, the good news is that you can bring an electric toothbrush just as easily as you would on domestic flights. 

Most countries follow similar rules to those set by the Federal Aviation Administration, especially when it comes to traveling with electronic devices like modern electric toothbrushes or battery-powered devices. 

Electric toothbrushes with built-in lithium-ion batteries are generally allowed, but loose or spare batteries must be carried in hand luggage and properly insulated to prevent short circuits.

Still, don’t assume all destinations are the same. Always check the policies of your airline and destination country before departure. Some airports may have additional screening for items like loose batteries, spare batteries, or lithium metal components, especially when packed in checked luggage or a checked bag.

If your toothbrush uses removable batteries, consider taping over the terminals or placing them in a battery case to meet safety regulations.

European Union and the United Kingdom

In both the EU and UK, travelers can bring an electric toothbrush in either carry-on or checked baggage without issue. These regions treat rechargeable electric toothbrushes the same way they do other electronic devices. You won’t need to declare your toothbrush on a plane, and most modern electric toothbrushes won’t raise any concerns at airport security.

However, if your toothbrush is part of a smart health device system (with Bluetooth or Wi-Fi capabilities), airport staff may inspect it briefly to ensure it doesn’t interfere with flight communication systems.

Asian and Other International Destinations

While many Asian and global destinations also permit toothbrushes on a plane, some may enforce stricter regulations for items with lithium metal or spare batteries. Double-check airport policies to confirm whether your powered toothbrush and its brush head should be carried in separate plastic bags or securely packed in your carry-on.

Countries like Japan and South Korea may require that battery-powered devices be packed in hand luggage only, especially during domestic transfers within those countries.
Singapore’s Changi Airport, for example, has specific signage in security lines advising travelers to remove all battery-powered personal care devices from their bags during screening.

Even if you’re switching from manual toothbrushes, it’s smart to travel with a rechargeable electric toothbrush that complies with international travel standards. Whether you pack it in your checked luggage or carry-on, staying informed will help you breeze through airport security with no disruptions.

For convenience and safety, consider choosing an electric toothbrush with a built-in USB charger, which is compatible with universal travel adapters and requires no voltage conversion.
