PORTLAND — More than 25 dentists from the Greater Portland Dental Society, along with their hygiene and assisting staff, will offer a day of free dental care on Nov. 5 as part of the second annual Dentists Who Care for ME event.

Free dental care, in the form of cleanings, fillings and extractions will be provided for adults who cannot afford dental care and have no insurance. Those services will be provided on a first-come, first-served basis at 15 dental offices, located from Falmouth to Gorham, at locations expected to be announced by Wednesday. Some patients may be referred to oral surgeons or other specialists who also will offer free care.

Patterson Dental, a national dental supply company with an office in Westbrook, will provide free supplies to the dentists. And, Oral B will donate toothbrushes and toothpaste for participants

Last year, more than 100 dentists, oral surgeons, hygienists, assistants and volunteers donated their services to treat some 600 people from the Portland area.

Dr. Demi Kouzounas, a co-organizer of the event, estimated the value of those treatments at about $100,000.
