Hundreds of people have been lined up outside the Veterans Memorial Coliseum in Phoenix since Thursday to meet with the dentist.
An estimated 2,000 people will receive free dental work Friday and Saturday. It's part of the fourth annual Dental Mission of Mercy.
The group says 1,500 volunteers will provide about $2 million in dental treatment over the next two days, including cleanings, filings, extractions and dentures.
It's all thanks to the Central Arizona Dental Society Foundation.
According to a recent survey, one in five Arizona adults and one in three Arizona kids have never had a dental check-up.
Treatment will take place Friday and Saturday from 6 a.m. to 6 p.m.
