Affordable Dental Care Options
We Accept Some Insurance Plans. For Uninsured or Under-Insured Patients, We Have a Plan!
Smile Alliance Club makes it easier—and more affordable—than ever to prioritize your dental health. This dental savings program is not insurance, but it offers access to high-quality dental care at reduced rates across hundreds of participating locations. With savings of 20% to 70% on dental procedures and bonus discounts on vision, hearing, prescriptions and more—it’s easy to see why members are smiling.
Two Plans. Endless Smiles.
