UCSB vs SDSU for undergrad

So I originally got waitlisted at UCSB (my dream school) and I thankfully just got in!

Here’s my situation though. I’m undeclared at both schools, but I for sure want to major in biology and go to dental school. I know that for dental it matters more about your gpa than which school you go to.

Both schools would cost about the same for me, but I was just wondering how much more difficult it will be at ucsb to get a great gpa in biology. I love ucsb and I would die to go but if it will harm my chances of dental school, I don’t want to risk it.
