A Brisbane dental clinic has been shut down and a dentist suspended following investigations into concerns about inadequate infection control standards, Queensland Health says.

Gap Free Smiles at Carina on Brisbane's east side has been ordered to close under the Public Health Act until proper standards are met.

Queensland's Chief Health Officer Dr Jeannette Young said investigations by officials this week raised concerns about inadequate infection control at the clinic.

She said Queensland Health would identify and contact people treated there to recommend they see their GP or call 13HEALTH to arrange testing for bloodborne diseases, including viruses such as Hepatitis C.

"The risk of transmission is very small," Dr Young said.

"We are acting from an overabundance of caution but investigations this week have revealed potential ongoing problems, and it's prudent to notify the public.

"Although we have no indication that any infectious or transmissible disease has been contracted by patients, it is important people be tested."
