Grettlin,
Dental schools DO NOT have a major preference for their applicants. As long as you've taken and satisfied the admissions course requirements for specific dental schools of your choice, you are ENCOURAGED to apply!
I believe that since the majority of applicants are Science majors (biological, chemical, and physical science majors) applying to dental schools, applicants with a non-science major will look heavily upon (they will stand out). Afterall, dental schools are very much like medical schools in the sense that they want their classes to be diverse, including their academic background.
Remember, as long as you've completed the admissions course requirements, dental schools will not care if you majored in "Under-Water Folk Dancing"!!!
I personally know that Univ. of Minnesota, Nova, and Temple do encourage non-science major (French, History, Economics, Anthropology, Engineering, etc.) to apply, but I'm sure MANY other dental schools are doing the same if not all the schools.
