A man suffering from a stomach tumour was left shocked after finding a rotten tooth in his bowl of yoghurt.
David Casey, 43, was having fudge-flavoured snack while watching TV and suddenly found himself biting down on something hard. He was disgusted to realise that the object was a tooth complete with filling, according to the Sun.
David, a formal corporal in the Royal Infantry, is worried that he could have caught something from the rotten-tooth, especially if he had swallowed it, and any mild infection could have been fatal.
"I bit down on what I thought was a piece of fudge. Straight away when I saw it, it looked like a tooth. It even had fillings as well," Casey said.
After finding the tooth, he put it in a bag and rushed to the Tesco superstore at Coventry's Arena Park shopping centre, from where he bought the yoghurt, to complain.
He was refunded 68p, after he told the Tesco staff about their brand Devonshire Style Fudge Yoghurt and the rotten tooth that he found in it.
"They refunded me the money for the yogurt and said they would send it back for further analysis. They have said sorry for the inconvenience but it's not inconvenient - it's disgusting. I could have someone's scabby tooth in my stomach right now and that would not have been nice," he said.
The former corporal said: "I have just completed nine weeks of chemo and I can't even afford to go swimming or anything in case I catch a cold. I have had to stay overnight in hospital when they thought I was coming down with something because my immune system is down."
Meanwhile, Tesco has sent Casey a £15 voucher, which he returned both times calling it an "insult."
Casey, now a lorry driver, asserts: "They sent me a copy of the report in to it and it said there's a chance the tooth could have got in to the yoghurt. But then it goes on to basically say it must have been my tooth."
"We shop there every week and spend about £120 there. I am furious, you don't expect to be treated like this. We have done them a favour by pointing this out," he said.
A Tesco spokesman said: "We take matters of this kind very seriously and we are looking into it."
