What a recommendation. Let's tell all of the students who just academically could not hack it to become a dentist retain an attorney to bully the school to essentially allow them to graduate at any means.
I know of cases when they were dismissed for serious non-academic reasons and hired attorneys and got back in. Let's let them become dentists so that they can degrade the profession by possibly becoming an insurance-fraud dentist or an abuser of their patients. Fantastic, just the type of dentist who I'd love to see representing our profession.
Then again, maybe schools and the ADA feel these students can be an important solution to "access to care" by filling those medicaid jobs.
OP, If you truly had serious personal factors that led to you not achieving adequate grades and leading to a dismissal and you feel that dentistry is your true passion, then do your best to make that dream happen. Now remember, second year is traditionally the most demanding year, but in no means does it get easier (written board, clinical boards) so really think about it.
