Illegal 'Bedroom Dentist' Clinic In B.C. Exposed

Conditions inside an illegal dental clinic in Burnaby, B.C., were dirty and disorganized, according to video of a raid by the College of Dental Surgeons of B.C. obtained by CBC News.

On Wednesday, the college issued a health alert for about 1,500 people who were patients of Tung Shen Wu, also known as David Wu, who is not qualified to practise dentistry in British Columbia.

Officials said Wu, who worked out of his home in Burnaby, may have exposed people to HIV and hepatitis B or C through improperly sterilized instruments.

The video shows that the living room of the house was set up as a waiting room.

The dental practice itself was run out of an apparently filthy bedroom in Wu's home, with a dirty floor and shelves covered with dust and debris, including plaster chips.

There is no evidence of any source for sterilized water.

The affected people, mostly Chinese-Canadians, are being urged to be tested for blood-borne viruses.

Ten years ago, Wu was the subject of a court injunction ordering him to stop his underground dental practice.

He told authorities he was leaving the country, but the new clinic was discovered in May.
