Do NOT compare yourself to the few posts on SDN, not all students are scoring 24's, in fact most students would be quite delighted to have your scores. I congratulate you on a job well done..All your scores are 20 or above and dental schools love consistency. With a sufficient GPA you will be receiving interviews dental schools.
Rest assured your scores are very competitive. I have worked in this field for many years and talk to a lot of students year round, you scores are fantastic!
Wishing you the best in your journey to becoming a dentist.
