Since Thursday, Sandra Scott has spent six hours driving back and forth from her home in the Sierra Foothills to the free medical clinic at Cal Expo.
Scott says she can't afford to see a dentist for chronic tooth pain she's had for the last three years.
"If it's between eating or paying a dental bill, this gives me an answer," she says.
The clinic, hosted by California Careforce, is a three-day event where people can get free eye exams and glasses; see a dentist or oral surgeon; and get a physical examination.
"Despite the Affordable Care Act, there are still many that go without access to health care, dental care and vision. And we see a real high need in vision and dental especially," says Julie Hirota, executive director for California Careforce.
Scott says she is thrilled about her chance to see a dentist.
"Anything they can do that will ease the pain. I haven't even got words for how much this means to me..that they do this is incredible," Scott says.
Organizers say they expect about 3,000 people to be treated this weekend. The event is open to anyone needing care.
The next clinic will be at Los Angeles County Fairgrounds in Pomona in February.
