A young woman with a painful jaw disorder has spoken of her shock at discovering her dentist was a convicted fraudster who had been struck-off.

The 28-year-old was stunned to learn, after he disappeared halfway through her private treatment worth £7,000, that Amir Kamburov had been imprisoned and struck off the General Dental Council register.

Kamburov today admitted two further charges of dishonesty and one of working as an unregistered dental professional at the Poplar Dentist in Morden, which he owned.

He was believed to have been living above the surgery although he gave his address in court as Addington Road, Urmiston - which does not show any results on a Google search.

The young woman, who insisted on remaining anonymous, has suffered from temporomandibular joint disorder, a painful problem affecting the joints between the lower jaw and base of the skull, for the past decade.

Amir Kamburov leaves court. 

She sought a specialist to fix the problem after years of trying different treatments which did not work.

She was due to give evidence to South West London Magistrates’ Court in Wimbledon today but Kamburov changed his plea to guilty at the last minute and she did not need to face him.

The dentist surgery has now closed down and is being used as flats.

The young woman, who did not want to be identified, said she paid him £7,000 for private treatment for the disorder which began when she met him in August 2011.

She said: "I had done my research and thought I had found someone in the area who was qualified.

"I was in so much pain I didn’t have a choice.

"It was a massive relief when the treatment started to work."

Amir Kamburov tried to avoid being photographed outside Wimbledon Magistrates' Court. 

She had tried everything for the pain, including Valium, anti-depressants and even Botox, which freezes the muscles, but she said it froze her smile and she did not want to have injections for the rest of her life.

As part of the disorder her jaw regularly dislocates if she yawns and she cannot sleep on the left hand side because it is too painful.

He attached so-called splits which jutted out of two of her teeth to stop her top and bottom teeth from meeting, as this aggravated the condition, she said.

She now wants them removed but cannot afford any more treatment.

She searched online for specialists near to her former home in Cheam and found Kamburov, who she said was always pleasant and helpful.

He gave her a jaw splint and she said her extreme headaches ceased so she began to trust him.

But her jaw became painful again in December 2012 and she tried to contact him by phone and email to organise an appointment but he ignored her.

She said: "He disappeared.

"I had no reply so I went to the practice and banged on the door.

"Someone came out and said he was in South Africa because his dad was ill.

"I found out later he was in prison."

Kamburov had been jailed for similar offences, she said.

Prosecutor Roz Wardell told the court today Kamburov had been arrested in October 2012 for fraud and practising dentistry unlawfully.

She said: "He pleaded guilty and in December 2012 he was given bail by the court.

"He was arrested again for continuing to practise dentistry and given seven weeks in prison for these offences.

"He was released in January 2013," Miss Wardell said.

It was soon after he was released that Kamburov got back in touch with his victim, who was in pain and in debt after shelling out thousands of pounds to him for treatment.

She said he told her his practice was being refurbished and he could see her at the Morden Dentist, run by Dr Ghafoor Manan in Crown Lane.

Dr Manan said Mr Kamburov transferred a lot of his patients to his practise and he was happy to see them. He often introduced the patients to the new dentist personally.

Dr Manan, who was also due to give evidence at the hearing, said: "I was astounded when I heard there was a previous conviction.

"I genuinely wanted to help him and his patients - it is very stressful to get struck off from the General Dental Council."

The prosecution alleged Kamburov saw the victim at Dr Manan’s practise without his knowledge and took impressions of her teeth, when he should not have been working.

Mr Kamburov admitted two counts of dishonestly failing to disclose information to make a gain for himself on July 20, 2012 and September 14, 2012, and one count of being an unregistered person practising as a registered dentist on August 1, 2013.

He will be sentenced by magistrates on Tuesday, November 4.
