dentistry is definetly harder to get into than optometry. The gpa requirements for most dental schools is getting to be close to what is required for a premed student to get into med school and of course caribbean schools excluded. 3.5gpa on average and above seems to be the trend in recent years of what is required and even then in a lot of cases recently people with a better gpa than 3.5 and above average dat scores dont get in to dent schools due to the inflated competition and limited seats. there is no such thing as a safety school as far as getting into dent school is concerned, but being a minority always helps at some schools.
