If you're widening participation you can apply to kings or qmul bc they assess holistically. I'm sure you can apply to the majority dental schools. I'm also guessing this 4th option won't be your firm or insurance choice so maybe it isnt your priority but find a 4th choice you're comfortable with (teaching style/interview style/opportunities offered ect.) . Birmingham have a cut off so check their website
Manchester apparently have high ucat cut off but I know someone with 2540 ucat that did an interview there a few years ago.
Leeds just changed to ucat from being bmat. I'm not sure but I think Newcastle is also high ucat. So those are my ones to be mindful of.
What I recommend is to type into Google: whatdotheyknow.com "insert uni name' ucat score
You'll find ppl have asked the dental schools for freedom of information requests on previous dentistry applicants entry scores n a levels ect. Try find the most recent years (a reply with 2020 data is less relevant to you than 2023 data).
Hope that helps and good luck with your application
