The purpose of the “pokes”, are to deter and to remind the tongue not to push against the front teeth. Oftentimes when a person has a tongue thrust or an improper tongue resting posture, the tongue rests too forward and against the teeth. The tongue spikes support keeping the tongue off the teeth, while the Spot Dot aids as a tactile cue to remind the tongue tip where it is meant to rest (up and off the teeth). Ultimately the goal is for the user to never contact the spikes because instead the user will be utilizing the Spot Dot feature for where the tongue tip should be.
