Dental Lifeline Network coordinates donated, comprehensive dental treatment for individuals with disabilities, who are elderly or medically fragile, and who cannot seek the dental care they need.. Since 1985, more than 120,000 of our nation’s most vulnerable individuals have received $380 million in life-changing, comprehensive dental care through our flagship program, Donated Dental Services (DDS). Approximately 15,000 dentists and 3,500 dental labs currently volunteer for DDS.
