If the toothpaste is in larger volumes, you should put it in your check-in baggage. Although it is not required, for safer choice, we highly recommend you place your toothpaste in a clear bag that can easily be removed from your carry-on during the screening process.
Each passenger is limited to one quart-size bag of liquids, gels and aerosols. Common travel items that must comply with the 3-1-1 liquids rule include toothpaste, shampoo, conditioner, mouthwash and lotion.
Toothpaste is considered a liquid by the TSA (Transport Security Agency), even though it's technically a paste. In fact, all pastes, gels, waxes, and lotions are also classified as liquids. And even today, these substances are still restricted by the 3-1-1 rule in hand luggage due to safety threats.
Any item that alarms or is unable to be screened will not be permitted in your carry-on bag. We recommend packing all liquids, gels, and aerosols that are over 3.4 oz or 100 ml in your checked baggage, even if they are in a secure, tamper-evident bag.
Toothpaste can be brought through TSA security in your carry-on as long as it is 3.4 ounces (100 milliliters) or less and placed in a 1-quart bag. If your toothpaste is bigger, put it in your checked luggage or purchase some upon arrival.
Liquids, aerosols and gels (LAGs) are all liquid items for aviation security purposes. This includes all drinks, toiletry and cosmetic items such as shampoo and shower gel, toothpaste, liquid/aerosol deodorant, hairspray, hair gel, mascara and foundation cream.
Flammable liquids and solids such as lighter refills, lighter fuel, matches, paints, thinners, fire-lighters, lighters that need inverting before ignition, matches (these may be carried on the person), radioactive material, briefcases and attache case with installed alarm devices.
Shampoo and conditioner — as well as and roll-on, aerosol, and gel deodorant — must be travel-sized and fit into one quart-sized, zip-top bag to meet standard carry-on bag requirements. If any of the containers are larger than 3.4 ounces, you will need to pack them in your checked luggage.
Do Toiletry Bags Need to Be Clear? TSA does not specify that toiletry bags need to be clear. However, when traveling with liquids, using a TSA approved clear liquid bag will help expedite the TSA process so agents can see everything easily without further inspection.
You cannot take containers larger than 100 millilitres or 100 grams, even if they are partially filled. For example, a 200 gram toothpaste tube that is half-full is not allowed. At the screening point all liquids, aerosols and gels in your carry-on baggage must be separately presented for screening.
Can I brush my teeth on a plane? Of course! Depending on the length of your flight, you should definitely brush your teeth at least once, especially after a meal. Food debris and sugary foods are the primary causes of plaque build-up in your mouth.
Containers larger than 100 millilitres or 100 grams, even if only partially-filled, containing liquids, aerosols or gels will not be allowed through the security screening point. For example, a 200 gram toothpaste tube that is half-full will not be permitted.
Any containers larger than 100ml will need to be packed into your check-in baggage or left behind. Partially filled containers larger than 100ml will not be accepted. Place the containers that you want to take in your carry-on baggage into a transparent, resealable plastic bag.
The main rule to remember is that you must not take any more than 100ml of a restricted liquid into the cabin of a plane, and those liquids should be placed into individual 100ml containers. Any liquid that you need more than 100ml of should be packed in your hold luggage.
Safety Razors: Because the razor blades are so easy to remove, safety razors are not permitted in your carry-on luggage with the blade. They're fine to pack in your carry-on without the blade. The blades must be stored in your checked luggage. The same applies for straight razors.
If you want to travel with your full-size aerosol containers of antiperspirant, hairspray, suntan lotion, shaving cream, and hair mousse, you can do so by packing them in your checked baggage.
Typical travel-size toothpaste tubes hold about 3.4 ounces, the maximum amount of fluids the Transportation Security Administration (TSA) allows you to carry on board a flight. If you are using the recommended amount and brushing two times a day, a 3.4-ounce tube will last for 9–10 brushings or about five days.
You can take any other medication you may need for your trip with you in your hold luggage. It's a good idea to keep a spare copy of your prescription or doctor's letter in your suitcase with your medication, just in case you lose your first copy or security need to make any checks.
Bag screening
Place laptops and large electrical items separately in a tray. Put coins, keys, mobile phones and other small items in your coat or hand baggage. Place your hand baggage and coat into a tray. Place any liquid items (important: see 'Liquids - 100ml rule' above), correctly bagged, into the tray.
Use Mouthwash in Place of Toothpaste: When toothpaste is unavailable, one of the most popular alternatives is to brush using mouthwash. To do so, dip the bristles of the toothbrush into the mouthwash. When the bristles are thoroughly moistened, proceed to brush the teeth as usual.
The FAA limits the total amount of restricted medicinal and toiletry articles, including aerosols, in checked baggage. The total aggregate quantity per person cannot exceed 2 kg (70 ounces) or 2 L (68 fluid ounces). The capacity of each container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).
