dentistry application confusion

so I’ve applied to Leeds, Liverpool, Plymouth, and Sheffield for dentistry have been rejected by Leeds and Liverpool and I don’t have much hopeful for Plymouth or Sheffield. I don’t want to do a gap year, and I’ve got an offer for biomedical sciences at Newcastle. I’m going to try and go through clearing to get Manchester or Bristol for biomed but I’m not sure that biomed would be able to provide a good job for me in the future. Maybe I’d go into finance after graduating, but I don’t know if I’d be able to get a job. Im just confused. Is trying to get Manchester or Bristol over Newcastle a good choice as well? Or shall I just stick with Newcastle?

Neither of these Unis will need to put Biomed into Clearing to fill the course.
Do you want a front-line health career dealing with people, or a researchers job sat in a lab - you choose. If you really want to do Dentistry, then a gap-year and reapplication would be a minor inconvenience - if you can't be bothered to do that, then you are clearly not that committed to Dentistry, and you need to look at alternative degrees/careers:

Sorry to hear that. What are your GCSEs and UCAT? With strong GCSEs, I'd definitely recommend taking a gap year, however if you really don't want to, there are other options available!

You seem to be assuming that university is required to have a good job in 4 years time, if the aim is now a finance job then a biomedical sciences degree seems a very odd choose.
Your teachers will have groomed you since an early age to believe that going to university is the automatic choose, it is not, unless university gives a clear and low risk path to the outcome you are aiming for.

That’s a really understandable position to be in — rejections make everything feel urgent and confusing.
Newcastle biomed is a solid degree in itself, and realistically the difference between Newcastle vs Manchester/Bristol for biomed matters far less than people think for future jobs. What matters more is what you do during the degree (placements, experience, skills), not just the name.
If you don’t want a gap year, sticking with Newcastle is a perfectly sensible choice. You can still reassess dentistry, healthcare, or even something like finance later once you’ve had time to breathe and plan properly.
