Can I Bring an Electric Toothbrush on a Plane? What to Know Before You Pack

If you’re packing for your next flight and wondering whether you can bring your electric toothbrush with you, the answer is simple: yes, you can. But depending on whether it’s in your carry-on or checked luggage—and whether it has a lithium battery—there are a few things you should know first. Here’s everything you need to know about flying with an electric toothbrush, so your oral care routine never misses a beat.

1. TSA Rules: Are Electric Toothbrushes Allowed in Carry-On Bags?

Yes, electric toothbrushes are allowed in your carry-on. TSA doesn’t classify them as restricted items, and you don’t need to remove them from your bag at security.

No liquid restrictions: As long as your toothbrush doesn’t contain a large toothpaste reservoir (most don’t), it won’t be subject to the 3.4-ounce liquid rule.
No screening delays: Electric toothbrushes can stay in your luggage—no need to place them in a separate bin like laptops or tablets.
Safe and easy to travel with: They pose no security threat and are treated just like razors or electric shavers.

Whether you use a rechargeable model or one with replaceable batteries, you’re good to go with your electric toothbrush in your carry-on.

2. What About Checked Bags?

You can pack electric toothbrushes in checked luggage, but there’s one thing to watch out for: lithium-ion batteries.

Removable lithium batteries: These should be packed in your carry-on, not in checked luggage, according to FAA safety guidelines.
Built-in batteries: If your toothbrush has an internal, non-removable lithium battery, it can usually stay in your checked bag without issue.
Risk of damage: Checked bags are often tossed around. If you’re concerned about your toothbrush getting cracked or turning on by accident, it’s better to carry it with you.

To be safe, pack it in your carry-on and avoid potential damage or issues with battery-related rules.

3. Do Airlines Allow Electric Toothbrushes During the Flight?

Yes, you can use your electric toothbrush mid-flight—especially on long-haul flights where brushing between naps or meals feels necessary. That said, there are a few etiquette tips to keep in mind:

Use it in the lavatory: Never brush your teeth at your seat. Head to the bathroom and be mindful of your time.
Bring travel-sized toothpaste: Make sure it’s 3.4 ounces (100 mL) or less to meet TSA rules.
Consider a travel brush head cover: It keeps the bristles clean and prevents water from leaking inside your bag after use.

On overnight flights, having your electric toothbrush in your personal item makes it easy to freshen up before landing.

4. Battery Guidelines: What to Know About Lithium-Ion and AA/AAA

Most electric toothbrushes use either rechargeable lithium-ion batteries or replaceable AA or AAA batteries. Each has its own travel considerations:

Lithium-ion batteries: These are regulated because they pose a small risk of overheating. TSA and FAA recommend keeping them in your carry-on.
AA/AAA battery models: Safe in both carry-on and checked baggage. If your toothbrush takes replaceable batteries, no special rules apply.
International flights: Check airline guidelines, but in most cases, electric toothbrushes are permitted just like other personal electronics.

If your toothbrush is rechargeable via USB, bring the charger cord. Most airports and hotel rooms now offer USB outlets for easy recharging.

5. Tips for Packing Your Electric Toothbrush

Want to keep your electric toothbrush protected and clean during travel? Here’s how to pack it like a pro:

Use a travel case: Most electric toothbrush brands sell compact, hard-shell cases that protect both the brush and the charger.
Bring a backup manual brush: In case your battery dies or your luggage gets delayed, it’s always smart to have a non-electric alternative.
Pack a few extra brush heads: Especially if you’re traveling for more than a week. It saves you from trying to find replacements abroad.

Keeping your toothbrush clean and easily accessible ensures you never have to skip your dental routine while traveling.

Yes, You Can Bring an Electric Toothbrush on a Plane—Just Be Smart About It

Your electric toothbrush is travel-friendly, TSA-approved, and airline-compliant. Whether it runs on lithium or AA batteries, there’s no reason to leave it behind. Just keep it clean, pack it in your carry-on, and brush with confidence—whether you’re at 30,000 feet or freshening up after a long flight.
