A mother in Ireland was left terrified after her 3-month-old baby boy suddenly became entirely inconsolable and wouldn’t stop crying one morning.

When she glanced inside his mouth during a feeding, she was stunned to discover what appeared to be a sharp, fang-like canine tooth.

The unusual case deeply surprised doctors, as the pointed, tooth-like structure had seemingly erupted from the infant’s gums completely overnight.

Concerned for her son’s health, Tara O’Byrne from Drogheda immediately rushed her young baby, Oscar, to the local hospital for a medical examination.

Doctors were puzzled by the finding and quickly referred the infant to a specialist children’s hospital for a more comprehensive evaluation.

At the specialist hospital, a pediatric dentist examined Oscar and determined that the structure was actually a rare neonatal tooth.

Because the early tooth was loose and posed a serious, immediate choking risk to the infant, the dental team carefully removed it.

The quick procedure was highly successful, and several doctors reportedly photographed the rare tooth for medical and educational purposes.

Most babies begin teething around six months, but a tiny percentage are born with natal teeth or develop neonatal teeth shortly after birth.

If parents ever discover an unexpected early tooth, they should seek a professional evaluation rather than trying to remove it themselves.
