Is Toothpaste Allowed In Carry On Luggage

Brushing with a fluoridated toothpaste is important. I personally think switching to a another toothpaste does not make it more effective. Probably not your toothpaste (although some people are sensitive to sodium lauryl sulfate which is in most toothpastes).

Never let toothpaste in your gums and teeth overnight, because the detergents and the fluoride can harm your soft and hard tissue. Swallowing toothpaste can cause stomach upset as well as other health issues if done consistently. You can think of toothpaste as a medicine.

The longer that your teeth are exposed to it, the longer the medicinal effects of the toothpaste have to work. Toothpaste does not kill bacteria in the mouth. A toothpaste is only as good as it is used, and for children, sensodyne is fine (especially if they can expectorate).

I might suggest that you start to use a toothpaste that contains an anti microbial agent such as triclosan.
