how stupid would it be if i dropped out to reapply to dentistry

for context dentistry was and still is my passion, ive done months of work experience, have talked to multiple dental profressionals and its a career i can really see myself doing long term and what makes me excited for the future..
The problem is, im doing optometry right now.
I took a gap year to reapply for dentistry but i got rejected again, (pre interview rejections because my ucat was bad) this really discouraged me and i let everyone get in my head and now im doing optometry at cardiff.
Ive only been here a week and its not the worst thing but i still see myself doing dentistry in the future, not optometry.
Let alone the actual day to day work, (i feel like optometry is very monotonous comapred to dentistry as someone who craves excitement and problem solving on a daily basis) the salary gap isn't great either, dentistry is basically double, thats obviously not the only thing and not why I want to do dentistry it just feels like im settling with a career that im not even excited about and doesn't even pay as well..
So this is actually insane but im genuinely considering trialing optom for a year at least giving it a fair chance and if i still dont like it, dropping out and reapplying to dentistry
but there are barriers to me doing this, first of all im 20 next month because i have an early birthday + already had a gap year so i'd be 22 starting uni because ive missed this ucat testing cycle so i'd have to do the ucat in 2026 and apply for 2027 which is actually insane.
i'd have to retake chem because i was 1 mark away from an A last year and i was only able to apply without retaking becuase i had contextual status which i've lost now after starting a new degree
so im not sure if its even worth it but dentistry is truly what i want to do
also i cant go abroad though ive considered it because its expensive + my parents wont let me
i was considering post grad but its even more competitive and expensive so im not sure
im just in a really hard position right now

Forget about your age, it's not important and if dentistry is your passion, you should definitely go for it BUT you need to check if you will actually be accepted if you drop out of your current degree. I've no idea how it works for dentistry but I remember when I very stupidly decided to not reapply to medicine and started my current degree, I quickly looked into dropping out but then realised that if I did, I'd automatically make myself ineligible to apply to most medical schools, so I had to see my degree through if I wanted to apply anyway. I suspect it might work similarly with dentistry.

wait really 😭 that worries me, i’ll definitely email them and ask thank you for letting me know
