The Gainesville Dental Group hosted its annual free cleaning on Friday at their offices on Thompson Bridge Road.

Dentist Paul Gannon said it’s the seventh year the practice has offered free cleanings, extractions and fillings to those in need.

Those who come for the free services don’t have insurance, and dental work can be expensive, Gannon said.

“We like to give back throughout the year, but this is our one big event,” he added.

Gannon said he hoped about 70 patients would be served.
