Sahara Dental Summerlin on Tropicana is great. The doctors and staff are always very helpful. They always stay on top of me and make sure I keep up with my schedule too ! They have state of the art X Ray technology so I can see my teeth on a flat screen. I recently got invisilign and have been happy with the service. My previous dentist was a nightmare. I'm glad I found this place. I brought my whole family in !
