Abstract: Customized, Reusable Flow-Through Toothpaste Tube Attachment: a plastic or similar material (20) consisting of a threaded entrance orifice (23) which can be affixed to the threaded neck of a toothpaste tube (15) forming a seal. The threaded entrance orifice (23) is in communication with a continuous passage (30) which leads to an exit orifice (35). Once the attachment forms a seal with the threaded neck of a toothpaste tube (15), toothpaste can be forced through the passage (30) and out through an exit orifice (35) by squeezing the toothpaste tube. As toothpaste flows out of the exit orifice (35) of the attachment, it can be applied to the bristles of a toothbrush or the like. The reusable attachment (20) provides the flexibility to customize the exit orifice of a toothpaste tube as well as the angle at which toothpaste exits the tube.
