It is likely that you have seen kids with a cleft in the lip sometimes continuing into the palate (or roof of your mouth) or tooth/teeth missing from birth. Well, these are what are called congenital anomalies or birth defects.
This is called clefting.. A cleft lip is a long opening between the upper lip and the nose. A cleft palate is an opening between the roof of the mouth and the nasal cavity. In the United States, oral clefting happens in 1 in 700 to 1,000 births, making it one of the most common major birth defects.
