We use Advant Dental in McKinney. They are on Custer north of 121 and south of 380.
http://www.smilemakerusa.com Dr. Safavi is absolutely wonderful and there is nothing bad I can say about her. I am not sure about her pricing, all is usually handled through my insurance, but the out of pocket seems reasonable based on previous dentists in CA.
Hope you have an enjoyable experience. I know those two words in connection with dentist really don't fly well. Good luck.
