Small Smiles, a network of dental offices, will open a new branch today in Manassas. This might seem like an ordinary announcement, but Small Smiles’ target market — in fact, its only market — is the 40 million children enrolled in Medicaid or SCHIP, the State Children’s Health InsuranceProgram.

While most dentists are reluctant to take these patients because they don’t get fully reimbursed for their services, Small Smiles has embraced these patients and turned a profit with a unique business model.
