A dentist who became addicted to ice was struck off after colleagues found bags of the drug at his practice.

Young Hoon Sun was working at Primecos dental and cosmetic surgery practice in Sydney's George Street when he became addicted to the drug after the death of his brother in 2010.

He took two months off work at the time and became hooked on the drug while trying to cope with his grief.

Colleagues reported the 44-year-old to watchdogs after finding bags of the drug at their practice.

Sun had his registration as a dentist cancelled and will not be able to apply to work on patients again for at least three years.

A NSW Civil and Administrative Tribunal heard how Sun became addicted to the drugs after struggling to cope with his grief after the death of his brother.

'In about March 2010 whilst the respondent was working at a number of surgeries, his older brother died in tragic circumstances and his death had a profound effect on him.

'The respondent took two months off work and whilst associating with persons whom he appears to have met at a hotel, he tried recreational drugs for the first time,' documents from the tribunal revealed.

He returned to work but continued using drugs, raising the alarm when he asked for a Valium tablet at work.

'Later, a bag containing a white powder was found in one of the surgeries which the respondent had previously used. The respondent denied any knowledge of this item.

'In August 2010, a further two bags of similar appearance were found in the clinic after the respondent had been practising there.

'One was full and the other contained a residue of white powder. The packets were handed to the police because it was suspected that they contained methamphetamine.'

Sun denied ever using the drugs and stopped working with the group but refused to submit to urine testing after they shared their concerns with the Medical Council.

In a bid to evade the tests he created false boarding passes to pretend he was on holiday and even pretended to have injured his leg to get out of it.

Giving evidence Sun said he had become his family's 'golden boy' after forging a successful career in Australia since leaving their native Korea.

He claimed to have even had his success documented by a Korean programme akin to Australia's 60 Minutes.

Following the death of his brother from an undiagnosed medical condition, he struggled to return to normal life, he said.

He pleaded for rehabilitation admitting that though he is now 'clean', he feared he could relapse.
