A mother was left in a panicked state when her 11-week-old baby grew a fang tooth overnight.
Tara O'Brien, from Ireland, went to check on her baby boy Oscar after a long sleep during the night.
But when he wouldn't stop crying one morning, she went to feed to feed him only to discover he had sprouted a giant spiked tooth.
She rushed Oscar to Our Lady of Lourdes Hospital - but doctors spent more time discussing what it was rather than working out the best solution for the newborn.
