You still got two years to decide what you want to major in, so relax and enjoy your college life for now.
The core curriculum at most colleges should expose you to many disciplines: English, biology, math, chemistry, physics, economics, fine arts, psychology, music, history, whatever. Whichever holds the greatest interest for you, declare your major in it when junior year rolls around. Meanwhile, you can take the dental pre-requisite courses and still remain undeclared, so no sense worrying about your major until the time comes to decide.
You can get into dental school on any major, as long as you took the pre-requisite courses. The world is your oyster.
P.S. In case you don't know what the pre-reqs are, they are: 1 year of freshman English, 1 year of biology, 1 year of general chemistry, 1 year of organic chemistry, 1 year of physics, and 1 year of calculus. Good luck!

Any particular reason why you don't like being a biology major? Just curious...
