While identifying the causes of tongue thrust, it is important to remember that the resting posture of the tongue, jaw, and lips are crucial to the normal development of the mouth and its structures. If the tongue rests against the upper front teeth, the teeth may protrude forward, and adverse tongue pressure can restrict the development of the ...
Tongue extrusion is normal in infants. Tongue thrusting can adversely affect the teeth and mouth. A person swallows from 1,200 to 2,000 times every 24 hours with about 4 pounds (1.8 kg) of pressure each time. If a person has tongue thrusting, this continuous pressure tends to force the teeth out of alignment.
An infant demonstrating the Babkin reflex: he opens his mouth when pressure is applied to both palms (8 seconds). The Babkin reflex occurs in newborn babies, and describes varying responses to the application of pressure to both palms. Infants may display head flexion, head rotation, opening of the mouth, or a combination of these responses. [22]
Causes: Quick consumption of cold foods and beverages or prolonged oral exposure to cold stimuli: Treatment: Removal of the cold stimulus from the oral cavity and thrusting the tongue towards the tip of the nose or roof of the mouth to relieve pain. Drinking warm water can also ease pain.
Perhaps the most preventable cause of damage to these reflexes originates from smoking. One study has shown that, when compared to non-smokers, the threshold volumes (the lowest volume at which one of these reflexes is triggered) for both the pharyngo-upper esophageal sphincter contractile reflex and reflexive pharyngeal swallowing is increased.
Health care providers in multiple states have reported a virus that can cause seizures, meningitis and other severe illnesses in infants under 3 months old,
There are some frequent and harmless cases of drooling – for instance, a numbed mouth from either benzocaine, or when going to the dentist's office. Isolated drooling in healthy infants and toddlers is normal and may be associated with teething. [1] It is unlikely to be a sign of disease or complications.
An exaggerated Moro reflex can be seen in infants with severe brain damage that occurred in-utero, including microcephaly and hydranencephaly. [6] Exaggeration of the Moro reflex, manifesting either as low threshold or excessive clutching, often occurs in newborns with moderate hypoxic-ischemic encephalopathy.
