What healthcare uni course to do??

I originally wanted to study Dentistry however, I doubt I'd get the A in chemistry
So now, i'm looking for an alternative course.
I know i want to study a course in healthcare but due to the wide choice i'm not sure which course to take.
I took Biology, Psychology, ICT which i'm likely to get As in.
However I'm struggling with chemistry so would like a course that doesnt require it.
I also looked at the possiblity of become a dental hygienest/therapist but you only need Cs, so doesnt seem like a challenge and it doesn't seem too interesting..
Any suggestions?

There's also the option of the 6 year dentist courses, which basically include a foundation year for those who didn't have the grades/subjects required for the 5 year course. Alternatively you can always re-sit chemistry to get the A you need, IF you don't get the mark you want.
