What pathway should i choose HELPPPP

I am applying to king college for their two year K+ program ( i am in year 12 right now ). I am stuck between choosing pathways.
1. Natural sciences and medicine which has genetics and biochemistry which i loveee
2. Dentistry which i don’t particularly like but i am not sure either and as you guys probably know kings college is one of the best schools for dentistry
Now i dont know which one to pick
Should i pick dentistry to make sure i know if i like it or not? Or pick natrual sciences?
