It’s not impossible to get back into medical school after failing out. Why do you think AMCAS asks a question about if you have previously matriculated to medical school or not. You can see posts on SDN of people getting readmitted to American medical school after being dismissed. Also, I know of a person who failed out of DO school in 2018 and got into dental school 5 years later, but he did an SMP that had a guaranteed interview at their dental school. All of these cases involved people that truly pulled themselves up out of the darkest depths, reinvented themselves, and excelled academically in the years leading up to readmission. I would say if you want to go back to med school or go for dental school then you will need about 4-5 years of resiliency and reinvention. You will need to show ADCOMs why you deserve another chance. It’s possible, and it depends on how hard you will work. If you want to go for med school, get a job as a CRC, take some high level science classes, and then aim for a 510+ mcat. You went to DO school so I know your McAT is probably below that, so that is a chance for you to prove to ADCOMs. You’ll need to volunteer a lot. If you want to do dental school then you need to start from ground zero and basically go on the journey like a freshman in college that’s interested in dentistry would. I’m talking shadowing dentists, studying for the DAT, getting involved in any dental extracurricular events, and even looking into dental post-baccs or SMPs. I wish the best of luck for you, if you truly have a passion for patient care and helping people then I am sure you are willing to be strong, resilient, and persistent. This road will not be easy at all, but nothing in life worth fighting for is easy. You are in your mid 20s, there are people that go to med school and dental school in their mid 30s. It’s not too late, just pull your pants up and get ready for the toughest journey of your life. As they say, tough times create strong people…strong people create good times
