Myofunctional appliances for Finger Sucking

Thumb sucking is a trait observed in humans, chimpanzees, captured ring-tailed lemurs and other primates. This usually includes bringing the thumb into the mouth and repeating the sucking action rhythmically for an extended period of time. It can also be completed with any organs within reach, and is considered for the individual to be calming and healing. When a child develops dependency, a “favored” finger to suck on usually expands.
