if denture powder is powder than it is probly not allowed on planes cuz it might look suspitious.
Denture adhesive does not come in cream form. It comes in paste, wafer, or powder forms. Theoretically, you may bring 3 ounces or less of denture adhesive paste in a clearly labeled container on a plane, but the reality is that it depends on the rules of the airline, and the judgment of the person inspecting your bags.
Super Wernet's Denture Adhesive Powder has been dscontinued. Check out Super Poligrip Denture Adhesive Powder. It's made in Ireland with the same 800 number. I think it's the same product with a different name. I found Super Poligrip at Walgreens.
