The act of manipulating and sometimes gnawing on small wooden or plastic implements designed for dental hygiene is a relatively common, albeit sometimes unconscious, habit. This behavior typically involves placing the pointed end of the implement between the teeth or simply holding and moving it around in the mouth. It is important to note that chewing differs from the intended use of removing food particles.
The motivations behind this practice are varied. In some cases, it provides a tactile or oral-motor stimulation that can be soothing or distracting, similar to fidgeting. For others, it may stem from a desire to quit smoking, acting as a substitute for the hand-to-mouth action and oral fixation associated with cigarettes. Historically, the habit could have arisen from attempts to dislodge persistent food debris or a lack of alternative oral hygiene tools in certain contexts.
