Oral health and dentistry

Hi, im currently a year 12 student deciding what i want to do next year and looking for some advice. I know the standard pathway to doctor of dental surgery is by taking biomed or science but am wondering is it also possible to enter from a bachelor of oral health by maintaining a high gpa and taking the gamsat since it also meets the subject prerequisite for anatomy, biochemistry and physiology? I feel like this option would provide more security as I would be able to work as an OHT if I dont get into dentistry. If this is a possible pathway would my application to dentistry be at a disadvantage to students studying science or biomed with a similar gpa and gamsat and how competitive is entry into doctor of dental surgery? Thank you!
