That was more showmanship than a demonstration of my personal teeth cleaning routine!

Either way, however much toothpaste you use, this could potentially help you get more out of the tube. The payback would be longer, but that's not really why most people buy stuff like this.

Regarding "HeyLaughingBoy"'s comment - that market would be tubes of caulk and glue/epoxy.

While in the industrial space most use the common "gun" style applicator with the large tubes of product, and certain other manufacturers (3M in particular) sell custom applicators for industrial use for certain products (oftentimes at an insane markup) - there is the space for both the DIY'er and "handyman" (as well as commercial maintenance).

They will typically use regular squeeze tubes, especially on smaller projects where the larger gun-style tubes are too much or wasteful (because they may only use a small amount, and even when capped off, the tubes will dry out/cure relatively rapidly, especially at the nozzle end - making them useless and wasting product/money).

There also might be a market for automotive window glass installers for the sealants they use (and a/c repairmen?); actually tons of markets like this when you stop to think about it!

When in doubt, don't sell to consumers, sell to businesses.

Find a business that buys product in tubes (protip: find industrial product in tubes and figure out who buys it!) and sell your product to them at a 10x markup as a cost-saving device.
