Apparently there is some confusion as to who has our dental coverage. Tri-State is our coverage for dental. The provider can call
866-463-9418 and forms are available at http://www.tristatewelfarefund.com/forms-and-documents/ . If your dentist calls Delta Dental you will be told you are denied. The dentist needs to contact Tri-State for your coverage.
I am sorry for the confusion, let me know if you have any questions.
