The company, Bite - Toothpaste Bits, has developed a toothpaste pill which can be purchased online and at some stores.

The pill becomes foamy like toothpaste right away after biting.

Its founder Lindsay McCormick developed the recipe hoping to create a product that will help reduce the amounts of toothpaste tubes that end up in landfills.
