A man on a Singapore Airlines flight from Wellington to Melbourne was finishing up his in-flight rice dish when he felt an unusual crunch.
Speaking to AAP, Bradley Button said he spat out what was in his mouth to find what he is certain is a tooth that was not his. He promptly "threw my guts up".
He said for the duration of the flight he felt unwell, sitting with "the idea of having someone else's body part" in his meal.
Mr Button had been visiting a friend in Wellington and was returning to Melbourne aboard flight SQ248 on Tuesday when he made the gross discovery.
Taking photos of the object, Button said while "it was without a shadow of a doubt a tooth", the flight attendant tried to tell him it was a small rock and she needed to take it away "for testing".
