FWIW; Back in 1957, when I first joined the U.S. Army, "Tooth-Powder" was required to be displayed in your footlocker, on the top tray, left-hand side, along with your other shaving gear consisting of a brush, shaving soap, a two piece razor, a pack of blades, a bar of bath soap and a soap dish!!!.
Yes brothers Al and Hank, I was issued brown "buckle-top" boots. I was also issued the Eisenhower uniform, TW's, Bermuda shorts, socks, and a Pith Helmet!
Then about a year or so later they took all the good stuff back and issued me a green "Bus Driver's" Uniform and black boots, all fit for the Queen's Ball, they said.
Many of us old timers were disappointed in the look of the new uniforms.
But we grew used to it, even learned to love it as time went by!
At that time in life Tooth paste was certainly available and used everywhere, even electric razors were popular, but the foot locker contents, and set-up, was required by Army Regulations...and I don't recall that changing until sometime in the early 1960's.
I haven't seen tooth-powder in quite sometime.....have to wonder if it's even still made.
I have used it, even liked the taste, but a small can of Pepsodent sure didn't seem to last very long.
