Hi, I think that it will be harder to get into dentistry through dental hygine/therapy, as this is a career itself, and its more or less same as dentistry. There is a shortage of dentists atm... (soon to change or has lol)... and wont take u on as u can get a job when u got a degree...
This is backed up as the open day at manchester stated it will not be a steppin stone for dentistry.
Thats my opinion and dont quote me on this, but ope it gave u a better idea?...
