Why Is Toothpaste Not Allowed On Airplanes?
Anything that you can pour, pump, spread, squeeze, smear, spray, or spill is considered a liquid and must follow the 3.4 ounces (100 ml) or less rule, and apparently toothpastes can be squeezed.
The reason of banning large quantity of liquids like toothpaste is for security purpose, terrorist attacks or bad guys can use those kind of liquids to made or hide explosive, so the reason is the safety and the security of the passengers a and the aircrafts.
There are attempts that involve liquids, acids or explosives that the security can not detect if they are in large quantities, so the TSA and other security tend to ban taking more than a personal use on board the airplanes.

Bye-Bye Quart-Sized Baggie For TSA!!

There is a Trend of Toothpaste Tablet on Amazon among travelers, because Tablets are not liquids, so they can be carried on planes without any limits.
A traveler says about the tablet toothpaste “These are part of my standard conference travel packing. I use a single hard-case suitcase that fits in an overhead bin, and the only thing I hate worse than checking a bag is having to fish out a baggie of liquids for inspection by the TSA. So I pack these for toothpaste, use the hotel products for other hygiene needs (conditioner makes for great shaving cream), and never worry about it. My bag stays closed, one less thing to meddle with.“
Final Thoughts
If you take a travel size toothpaste which is less than 3.4 oz (100 ml) inside your transparent toiletry bag, you will not be asked any question in the security checkpoint.
If you are traveling to a place where you know there are no toiletries or you will need to pay some extra money to get your toothpaste, it may be smart to pack an extra tube of toothpaste, especially if local shops are difficult to find.
