Air travel has become increasingly complex, demanding attention to seemingly insignificant items. Even an everyday object like an electric toothbrush can present unexpected challenges if TSA guidelines aren’t followed.
The Hidden Risk of Lithium Batteries
Electric toothbrushes commonly utilize rechargeable lithium batteries. While not all pose a threat, these batteries can overheat or short-circuit. The TSA has intensified inspections due to a rise in onboard incidents.
This isn’t unfounded concern; the FAA reported numerous in-flight battery-related incidents in early 2025 alone, some leading to precautionary landings. Consequently, any device containing a rechargeable battery faces increased scrutiny.

How to Transport Your Toothbrush Safely
The key rule is that any item containing a lithium battery must be carried in your hand luggage, never checked. In the event of an issue, the crew can respond swiftly; a checked suitcase offers no assistance.
While toothbrushes powered by standard batteries pose no issue, those charged via a base or USB are best placed in your carry-on. Furthermore, some travelers cover or enclose the brush head in a case to prevent accidental activation during transit.
Other Devices Under Scrutiny
Electric toothbrushes are not the only items attracting TSA attention. Other devices include:
- Cordless irons and curling irons
- Airbrush makeup devices
- LED masks
- Electronic massagers
- Devices that run on butane gas
The common thread is lithium batteries or fuel. These necessitate careful management onboard aircraft. Even seemingly small items can become hazardous if mishandled.

Practical Tips for Safe Travel
To avoid complications and potential fines:
- Pack your electric toothbrush in your carry-on luggage.
- Ensure it’s switched off before security screening.
- Use a case or cap to prevent accidental operation.
- If unsure about the battery type, adhere to the TSA’s advice: “When in doubt, leave it out.”
Reviewing your toiletries before departure may seem trivial, but it can prevent significant issues. An improperly handled toothbrush can trigger extra scrutiny or even fines.
Modern travel requires attention to detail. A seamless journey begins with careful packing. Don’t underestimate the potential impact of your electric toothbrush; it could lead to unexpected airport delays and anxieties.
