Hello Akash

To be honest Pharm D and BDS are totally two different things and can not be really compared. It totally depends on your choice and passion. But still I'll go through some basics

On doing BDS you would be able to interact with the patients and do clinical duties. You would be dealing with the ailments directly. Even though it is basically about the teeth but there are many opportunities,if you do it well. Dental surgeons do perform big surgeries as well.

For Pharm D, you are playing it back stage. You are not directly dealing with patients but produce medicines that ultimately helps in curing ailments. You can be a clinical pharmacist, a drug inspector etc.

So choose the field of your choice and do the beat in it. There are plenty of scopes in all courses.

Good luck
