There are many recorded examples of children born with teeth. Sean Keaney (UK) of Newbury, Berkshire was born on 10 April 1990 with 12 teeth. They were, however, extracted to prevent possible feeding problems. He grew his second full set of teeth at 18 months.
Molars usually appear at 24 months, but in Pindborg's case (published in Denmark in 1970), a 6-week premature baby was documented with eight teeth at birth with four in the molar region.
