Toothpaste applied to the heart of the foot does not cause bedwetting, and in the unlikely event that bedwetting does occur, it is not caused by toothpaste applied to the heart of the foot.
Bedwetting is partly physiological, for example, children under 3 years old may wet the bed due to incomplete intellectual development and urinary habits, or adults may wet the bed if they are overworked or drunk. In addition factors such as urogenital disorders, neurogenic bladder, overactive bladder disorder and inflammatory bladder diseases can also cause bedwetting and have nothing to do with behavioural factors such as applying toothpaste.
