Of the 100,000 working dentists in America, two of them are doing the work for free Friday.

More than 100 million Americans are without dental insurance and that number continues to grow. But an Onalaska dental office is reaching out to help those who don't have dental insurance.

Valley Dental in Onalaska is donating all of its dental care with a staff of five hygienists and several volunteers from dental programs at UW-L and Mankato State.

The dentists are hoping to make a difference by providing everyone with care.

"We opened the doors at eight but people have been here for over eight hours waiting to get in," said Mike Gavin, owner of Valley Dental in Onalaska.

The dental office is providing patients with work like cleanings, fillings or extractions for free, on a first-come, first-serve basis. And dentists say people were waiting outside in line before midnight.

"Some of the things we see here are tremendous needs, a lot of oral infections a lot of pain, and no where to really go and have these treated people that might not have insurance might not have the ability to pay for some of this but it's nice to do a little something and give back," Gavin said.

Those who came to get treated, say they're able to save a lot of money and get rid of pain.

"Most dentists don't cover with the BadgerCare so I figured I'd come down and get it done and finally over with because it's been bugging me for over a year or so," said Nick Blair, a patient.

For patients, receiving dental care for free is a big deal. But for dentists:

"There is no question that there is a lot of dental work out there and a lot of people don't have the means to have some of it taken care so it's nice to do something, as small as it might be but to still give back a little bit," Gavin said.

"It's great because you know a lot of people in the community don't have dental insurance and it's great that they you know, are doing this for people," Blair said.
