There are many listings of dentists online, including MouthHealthy.org, which is run by the American Dental Association. Other good listings include phone directories, such as YellowPages.com, and business listing websites with user reviews, such as Yelp.com.
Yelp.com and YellowPages.com provide user reviews as well as listings of dentists. Use the reviews to help find a high-quality dentist among the listings. However, be wary that there is no filter to prevent users from posting false reviews or to prevent dentists from posting shill reviews. To find dentists on Yelp.com or YellowPages.com, type "dentist" into the search bar along with your location. Use the various sorting options to narrow your results, including rating and distance. Both websites also provide a map to explore search results.
