<unk>  extrusion is normal in infants.<unk> ing can adversely affect the teeth and mouth. A person swallows from 1,200 to 2,000 times every 24 hours with about of pressure each time. If a person suffers from<unk> ing, this continuous pressure tends to force the teeth out of alignment. People who exhibit a<unk>  often present with open bites; the force of the<unk>  against the teeth is an important factor in contributing to "bad bite" (malocclusion). Many orthodontists have completed dental treatment with what appeared to be good results, only to discover that the case relapsed because of the patient's<unk> . If the<unk>  is allowed to continue its pushing action against the teeth, it will continue to push the teeth forward and reverse the orthodontic work. Speech may be affected by a<unk>  swallowing pattern. Sounds such as , , , , , and are produced by placing the<unk>  on the upper alveolar ridge, and therefore a<unk>  may distort these sounds. Chewing and swallowing with dysfunctional muscle patterning (as in a<unk>  is not as effective as a normal chewing and swallowing motion.
