Natal teeth are seen:

# Natal teeth are seen:

A. Within first 30 days of birth

B. Erupt at three months of age

C. At the time of birth

D. At 6 months of age

The correct answer is C. At the time of birth.

The prevalence of natal teeth (teeth present at birth) and neonatal teeth (teeth that erupt during the first 30 days) is low. Leung conducted a retrospective study of hospital records of 50,892 infants born in Calgary, Alberta (Canada). 27 These records identified 15 infants found to have natal teeth, a prevalence of 1 in 3392 births. In another survey Kates and colleagues found the calculated prevalence of natal teeth to be 1 in 3667 among 11,000 infants when the survey information was obtained indirectly; however, in a group of 7155 infants actually examined, the prevalence was found to be 1 in 716.28.
