What makes you think that the pages are not being index?
Looking at your sitemap at http://www.dentistinlittlerock.com/sitemap.xml I see 10 different pages listed. Two of these are a duplicate listing of the home page so you really have 9 separate pages listed there.
Looking indexed pages on Google I see all 9 pages listed: http://www.google.com/search?ie=UTF-8&q=site%3Adentistinlittlerock.com
So it looks like all of the pages have been indexed. If you have a different sitemap please list it so we can take a look at it.
Thanks
