How We Rank Dentists

Our ranking uses Bayesian averaging to balance star ratings with review volume. This prevents a dentist with one 5-star review from outranking an established practice with hundreds of 4.8-star reviews. The formula weighs both rating quality and the statistical confidence from having more reviews.
