How much toothpaste do I need to travel?

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.
