Not too good GCSEs but want to go to KCL dentistry

My GCSEs are 999998888777 but 3 of my 9s are resits. I have no extenuating circumstances for resits. KCL states that they accept gcse resits for dentistry but others who have got the same or better results the first time will be favoured. Do I still have a chance at KCL dentistry? I have a very high UCAT
Please be completely honest and harsh

what subjects r the resits in?
