Dental is won in the map, not on the page
For a dentist the three results in the local pack take most of the clicks and the organic listing underneath takes what is left. That changes where the work goes: the Google Business Profile, how close the practice is to the searcher, the review count and how recent those reviews are, and whether the name, address and phone match across every directory that has ever listed the practice. A beautiful site with a neglected profile loses to an ugly site with a tended one.
