Two tubes or three: choosing your DCXC pack

We pack our mint toothpaste in twos and threes, same tube and same paste either way. Here's what's on our ingredient list, how long a tube lasts and where to keep the spares.

What's in our tube

We build our mint paste on sodium bicarbonate, with hydroxyapatite and the amino acid arginine. We leave out sodium lauryl sulfate and parabens, and we name every ingredient on the carton and on the tube. The two-pack and the three-pack carry exactly the same list.

How long a tube lasts

Each of our tubes holds 100 g, printed as 3.53 oz. A pea-sized dab weighs about a gram, so at two brushings a day one person uses about two grams, and a tube lasts roughly seven weeks. Share it between two people and it lasts about three and a half. The 3.53 oz size also fits standard carry-on rules for flights.

Two tubes or three

Our smaller pack holds two tubes and our larger one holds three. The paste is the same, so it comes down to how many tubes you want at once. We show the per-tube price next to the pack price on our home page so you can do the math before you order.

Where to keep the spares

Keep spare tubes on a dry shelf at room temperature until you open them, with our cap screwed tight so the paste doesn't dry out. Away from damp, the carton stays in good shape too. We like to drop one unopened tube in a travel bag and leave the rest in the bathroom cabinet.
