Hi,

Well academically it is possible but it requires a lot of hard work. You will have a lot of syllabus to cover in dentistry and then at the same time study for best as well. And also you need to look for whether your college will ask for a penalty if you forfeit your admission. If you are able to balance your studies and don't have any other problem pertaining to the administration then you are good to go.

I hope this helps.

All the best and take care.
