AADSAS itself has a decent status update system that indicates the current status of your application at every dental school. Please note that it is common for the status to change a few days before or after a milestone occurs (like being accepted or receiving an interview).
You can also join the member driven DDS Applicants resource by Student Doctor Network to get the latest updates from the current pool of applicants. This website will indicate members’ GPA, DAT Scores, the day they submitted their AADSAS application, as well as many other details allowing participants to get a good idea about each dental schools’ stage in the admissions process.
