Can I Bring an Electric Toothbrush on a Plane? 2025 Guide
Have you ever packed your bag and wondered if your electric toothbrush would make it through airport security? When it comes to air travel—particularly if you’re flying internationally—knowing what’s allowed and how to pack it can save you from unnecessary hassles.
We’ll unpack everything you need to know about bringing an electric toothbrush on a plane.
And if you’re curious about other tools like scissors, sunscreen, electric razors, and more, read our comprehensive guide to air travel with grooming tools–domestic and overseas.
1. TSA Rules for Electric Toothbrushes
When flying within the U.S., the Transportation Security Administration (TSA) makes it clear: Yes, you can bring an electric toothbrush on a plane, either in your carry-on or checked luggage. However, there are some nuances depending on the type of toothbrush and its power source.
1.1. Battery-Powered Toothbrushes
Most electric toothbrushes are powered by AA or AAA batteries, which are permitted in both carry-on and checked baggage. These pose no significant risk and won’t cause any trouble at security checkpoints.
KEEN TIP: If your toothbrush takes removable batteries, pack a spare set in your carry-on (and if they’re lithium–not your checked bag). Batteries are much easier to replace at home than during your trip.
1.2. Lithium-Ion Rechargeable Toothbrushes
Here’s where it gets tricky. If your electric toothbrush uses a lithium-ion battery, pack it in your carry-on luggage. Lithium batteries are prohibited in checked baggage because they can overheat and pose a fire risk. If a lithium-containing item should fail and catch fire, flight attendants are trained to put it out which they can’t do if the item is in the cargo hold in a checked bag.
KEEN TIP: If you’re unsure about your toothbrush’s battery type, check the manual or manufacturer’s website before your trip.
2. Packing an Electric Toothbrush for Air Travel
Packyour electric toothbrush correctly SO it stays functional and hygienic throughout your journey. Here’s how to do it:
2.1. Carry-On vs. Checked Baggage
From a practical standpoint, on long flights, you might want to freshen up mid-flight, so pack it in your carry-on—just don’t forget your travel-sized toothpaste (yes, toothpaste under 3.4 ounces is TSA-approved).
Whether you pack it in a carry-on or in your checked bag, here are some tips:
- Wrap it in a soft cloth to cushion it
- Ensure it’s off to prevent accidental activation
KEEN TIP: Use toothbrush head covers to keep bristles clean, whether in your carry-on or checked luggage. If you are less organized, like me, and don’t have a toothbrush head cover, just pull out the toothbrush head, put it in a clear zip lock bag and pack it with the unit.
2.2. Accessories and Charging Cords
Don’t forget to pack:
- Charging cords or docking stations if your toothbrush is rechargeable
- Plug adapters for international travel if needed. Most chargers are dual voltage, but check before you leave
3. Flying Internationally with an Electric Toothbrush
When flying internationally, the rules largely align with TSA guidelines, but a few extra precautions can help you avoid hiccups.
3.1. Carry-On or Checked Bag?
Most countries allow electric toothbrushes in both carry-on and checked luggage, following the same regulations as the TSA. Lithium powered toothbrushes and lithium spare batteries must go in a carry-on bag.
3.2. Adapting to Voltage Differences
In many countries, the voltage differs from the U.S. standard (110V). If your electric toothbrush charger is dual voltage, bring an adapter. If it isn’t dual voltage, you’ll need a power converter and an adapter. Adapters only change the plug shape, not the voltage.
KEEN TIP: Some modern electric toothbrushes come with dual-voltage chargers, making them compatible with various electrical systems worldwide. For instance, certain models of the Oral-B Genius series include a dual-voltage smart charger. Always verify your charger’s voltage rating, typically found on the base of the charger or in the user manual.
KEEN TIP: I have a universal travel adapter as shown above with surge protection which safeguards my devices against voltage spikes and it’s compatible with different plug types. It works great. These adapters are widely available at electronics stores and online retailers.
If your charger is not dual-voltage and you spend a lot of time in a foreign country, consider purchasing a compatible charging base designed for the voltage of your destination country. This approach can be more convenient than using a voltage converter and ensures that your toothbrush is always optimally charged.
4. Some Additional Considerations
4.1. Accidental Activation
An electric toothbrush turning on in your bag can be embarassing whether it happens at airport security or in the cabin. To avoid this:
- Remove the batteries
- Ensure the toothbrush is off
- Pack it in a case that prevents accidental button presses
4.2. Quarantine Rules
Australia and New Zealand enforce strict biosecurity laws to protect their unique ecosystems from potential threats. While electric toothbrushes are generally permitted, their biggest concern is that they are clean and free from contaminants.
The Australian Border Force says any item that appears dirty or contaminated could be subject to inspection. They’re really not looking for toothbrushes per se; just make sure that toothbrush is clean and toothbrush heads are covered to avoid potential issues.
New Zealand’s biosecurity regulations are similar. Toothbrushes, are typically not a concern unless they are visibly dirty.
KEEN TIP: No matter where go, it’s a good idea to disinfect your toothbrush head with a sanitizing wipe before your trip, and when you arrive at your destination.
5. Using an Electric Toothbrush Mid-Flight
Long-haul flights can leave your mouth feeling dry and stale. Here’s how to freshen up with your electric toothbrush without annoying fellow passengers.
5.1. Finding the Right Time
Use the toothbrush during quieter times, such as after meals or before landing, when bathrooms are less crowded. Keep your routine quick and efficient.
5.2. Noise Considerations
Some electric toothbrushes are noisier than others. To minimize disruption:
- Purchase a quieter model for travel
- Leave it in your bag and use a manual toothbrush when you’re on the plane
6. Frequently Asked Questions (FAQ’s)
6.1 Can I bring an electric toothbrush on a plane?
Yes, according to the Transportation Security Administration (TSA), electric toothbrushes that are not powered by lithium batteries are permitted in both carry-on and checked baggage.
6.2 Are there any battery restrictions for electric toothbrushes on planes?
Devices containing lithium metal or lithium-ion batteries must be carried in carry-on baggage.
6.3 Do I need to remove my electric toothbrush from my bag during security screening?
No, you you can leave your electric toothbrush in your carry-on during the security screening process.
6.4 Can I bring spare batteries for my electric toothbrush?

6.5 Can I use my electric toothbrush during the flight?
Yes, you can use your electric toothbrush during the flight, especially on long-haul journeys. However, be considerate of fellow passengers and use it in the lavatory to maintain hygiene and privacy. I once saw a seatmate brush her teeth at her seat so clearly not everyone knows this.
6.6 What should I do if my electric toothbrush accidentally turns on during the flight?
If it’s in the overhead bin, wait until you can safely get out of your seat to go into your carry on bag to shut it. It won’t interfere with any flight signals; the worst part is a bit of embarassment. To prevent accidental activation, make sure it’s turned off before packing.

Remember to pack devices with lithium-ion batteries in your carry-on luggage to comply with safety regulations. Utilizing protective cases and ensuring your toothbrush is turned off or has batteries removed can prevent accidental activation and damage.
For international journeys, be mindful of voltage differences and equip yourself with appropriate plug adapters or converters.
These simple steps ensure your electric toothbrush accompanies you safely and effectively, keeping your smile bright wherever your adventures take you.
