GO TO TEMPLE!
its a decent school... the clinical there is awesome, just ask dr.badvibes 😀
and if you are concerned about safety... well ...pretty much any school with a decent clinical is going to be in a bad neighbourhood, thats how it works 😛
for instance, maryland =good school, but its in baltimore, ranked 11th worst in country
wasting another year is not worth it, firstly, its getting more competitive to get into dental school. If next year's applicants are super good, then you might not have a chance, and temple wont be an option for you because you already rejected them once. and i know they dont let you defer admissios.
secondly, i have also heard that it looks really bad on your application when you recieve an acceptance, which you reject and reapply. im not sure about this, but you should find out if schools have access to your previous aadsas records, because if they do, then they will know what you did.
