If you’ve gotten used to the mild and natural flavor of Tom’s toothpaste, it’s hard to go back to the harsh mint of the run-0f-the-mill brands. We’re glad to add Tom’s to our carry on (you know how much we hate to check a bag); and these 3 oz. or less sizes are TSA friendly. You can also bring mouthwash, deodorant and bar soap. Find them all at Drugstore.com.
