A man was shocked to discover his blocked nose was caused by a tooth growing in his nostril.
Zhang Binsheng, 30, went to the doctors after he had struggled to breathe out of his nose for months.
Zhang, from China, said he had been struggling to sleep for months and also had a constant smell of ''decay'' in his nostrils.
The doctors advised him to go for an X-ray, where a shadow of ''high density'' was discovered at the back of his nasal cavity.
He was left stunned when medics explained that they believed it to be his long-missing tooth.
The offending tooth had fallen out his mouth after he fell from the third floor of a mall at the age of 10 and had somehow managed to root and grow in his nose.
Doctor Guo Longmei, of Harbin Medical University in China, said that, because the tooth was Zhang's, his nose had not rejected it as 'foreign object'.
The tooth was removed from his nose and he is now said to be recovering well.
