Hello student ,

If you are animal lover then Veterinary will be best choice.There are many job opportunities once you finish you course. But if we compare then both field are good which depends upon particular's interest . So ask yourself what makes you happy and satisfied in life, how much money could satisfy your pocket and where you want to see yourself in future.If you have compassion towards animals and want to work for their betterment, veterinary medicine may be the field of your interest and if  you are interested in helping people who obviously can speak about the pain ,then you should opt for dentistry. It's a field whose boundaries are increasing day by day. In dentistry or in any health sciences field you have to do multitasking.

Hope it helps !
