If your applying for admissions for fall of 2006, I think september is way to late. Keep in mind it will probably take AADSAS 8 weeks to process your application. So dental schools will probably get your app in november or so. Many schools(private) will have 50% or more of their class filled by this time and your chances for admittance start to dwindle down unless you can pull 20+ on the DAT and have a really good GPA. Thats just my opinion. Last year I submitted AADSAS at the end of september and that was the case for me. Hope this helps.
