A family owned company, Nakanishi Dental Laboratory was founded in 1953 with the goal of providing superior dental products. We make every effort to give our clients the best quality restorations while also maintaining a dedication to the highest standards in client service. Located in Washington State, NDL is one of the west coast’s largest and finest dental laboratories, producing high-quality, custom crafted restorations that are designed to fit perfectly.

At Nakanishi Dental Lab, we specialize in a high level of technical partnerships with our clients, allowing us to assist on the laboratory portion of treatment planning for complex restorative cases. Our laboratory team consists of more than 40 dental technicians and we are currently certified/specially trained in all major implant systems.

Nakanishi Dental Laboratory is associated with many dental organizations, including the NADL/NBC, Washington State Dental Laboratory Association, and the Dental Lifeline Network. As of October 2011, NDL became the first privately owned laboratory in the state of Washington to achieve accreditation from the Dental Appliance Manufacturers Audit System (DAMAS). NDL is also a partner in the Dental Resource Alliance Group and an honorary member of the University of Washington Dental Alumni Association.
