Final answer:
Approximately 50% of natal teeth are supernumerary, which means they are extra teeth that exceed the normal number of teeth for a child.
Step-by-step explanation:
The correct answer is B. 50% of natal teeth are supernumerary.
Natal teeth are teeth that are present at birth or erupt in the first month after birth. They are quite rare, occurring in about 1 in every 2,000 to 3,000 births. Out of these natal teeth, approximately 50% are supernumerary teeth, which means they are extra teeth that exceed the normal number of teeth for a child.
Natal teeth can sometimes lead to feeding difficulties, discomfort, and other complications, so it is important for parents to seek dental advice if their child has natal teeth.
