The second annual Operation Troop Treats program will offer local children a free toy and a chance to help out soldiers overseas.
Kool Smiles dental care locations in Fall River and New Bedford will accept unopened Halloween candy during normal business hours through Wednesday.
One toy will be given for every 25 pieces of donated candy.
More than a ton of candy was collected during the same collection drive last year.
Donations will be packed into care packages and shipped to troops overseas, as part of Operation Gratitude.
