Despite significant advances in dentistry and our ability to prevent many oral healthcare issues, dental disease remains a significant and widespread problem in America, particularly for low-income seniors. If improvements in access, affordability, education and awareness do not occur, oral disease and related health issues will become an increasingly prevalent and costly public health issue for our aging population. Establishing and maintaining good oral healthcare is critical to successful aging.

The mission of the Gary and Mary West Senior Dental Center is to provide affordable, high-quality oral healthcare with comprehensive education, clinical, and wellness services for seniors in need, enabling them to live healthy and productive lives. The Senior Dental Center links high-quality and affordable oral healthcare with a suite of nutrition, case management and wellness services offered through the Gary and Mary West Senior Wellness Center, creating a one-of-a-kind, integrated community-based system of care for older adults.

Research, policy and advocacy are part of our efforts to provide solutions to the lack of oral healthcare for seniors. We are launching several research studies to demonstrate that our model of care positively impacts health outcomes, lowering the cost of healthcare.


Preventive care and education are key elements to optimal oral health. We provide thorough exams to evaluate a patient’s total health, not just teeth and gums. We educate each patient on the importance of routine cleanings, flossing and early detection to help ensure long-lasting, positive results and prevent extensive dental disease and complex treatment later.


We provide a wide range of high-quality oral healthcare  services in a state-of-the-art facility with passionate staff, excellent materials and high-tech diagnostic and treatment instrumentation for best results. Our goal is to ensure our senior patients achieve and maintain long-term oral health, regardless of their ability to pay for services.


Our model of providing care within a thriving senior wellness center ensures seniors receive holistic, patient-centered care. We’re dedicated to creating a place of trust and safety to deliver personalized care, making dental visits as comfortable, efficient and pleasant as possible. The staff at the Senior Dental center provides linguistically and culturally appropriate education and information to patients about the importance of good oral health and work with primary care providers to ensure continuity and coordination of care.
