106 plotted practice locations and 113 licensed dentists in Ontario, across 3 ZIP codes, from the public National Provider Identifier registry.
Ontario has 106 dental practice addresses on the federal registry, staffed by 113 licensed dentists. At 49 of those addresses at least one dentist has held an NPI since the original 2005–2007 registry rollout — nineteen or more years in practice.
That density is what sets price. A buyer looking at Ontario is comparing every door here at once, and a seller who prices without knowing the count is guessing. Nothing on this page is for sale; every listing this brokerage represents is confidential.
