More than 2,000 U.S. military veterans are expected to pass through the 17th annual Veterans StandDown event this year.

"Stand down" is a military term that refers to a brief period of time for a soldier to leave an active combat area, rest and regain strength before returning to battle.

There are more than 70 services and 1,000 volunteers helping veterans with everything from DES benefits, legal and ADOT services, haircuts, employment, medical, vision and dental work, just to name a few.

Many of the veterans at the event are accompanied by their furry best friends.

For the first time ever, dental services are available at this years event.

"There a lot of neglect, years and years of neglect. There's some people who have 12, 13, 14 teeth pulled at once," said Kevin Conroy, executive director of the AZ Mission of Mercy, the charity behind the free dental work.

"Vulnerable" is how state representative and fellow dentist Regina Cobb describes the veteran community they are helping. Cobb took a break from a special session to attend the event.

"We're talking, we're going through the opioid special session, and that is huge also in the vet community. They need medicine, they need dentistry," said Cobb.

The event runs through Saturday. For more information, visit the VA's website.
