1. An intraoral stimulation device configured to be positioned in a mouth of a patient, the mouth comprising a tongue, upper teeth, lower teeth, and a hard palate, the device comprising:
an upper bite block configured to be positioned on the upper teeth;
a lower bite block configured to be positions on the lower teeth and different and separate from the upper bite block;
a first sensor mounted on the upper bite block, the first sensor being configured to monitor at least one of a position of the tongue and force exerted by the tongue against the first sensor, the first sensor being configured to transmit a signal encoding tongue information;
a second sensor mounted on the lower bite block, the second sensor being configured to monitor at least one of a position of the tongue and force exerted by the tongue against the second sensor, the second sensor being configured to transmit a signal encoding tongue information; and
one or more electrodes mounted on at least one of the upper bite block and the lower bite block, wherein the one or more electrodes mounted on the upper bite block being configured to deliver electrical stimuli to the hard palate and the one or more electrodes mounted lower bite block being configured to deliver electrical stimuli to a tongue extensor muscle when the tongue information indicates that the tongue has moved from a desired position to an undesired position in the mouth, the electrical stimuli causing the tongue to move from the undesired position to the desired position in the mouth.
