About placement, in my college they don't provide any placement we only search for the jobs outside but we do intership in our college itself but they provide stipend around two thousand per month and we need to do intership around one year

There's nothing like placements as such but after completeing 4 years , 1 year rotatory internship is compulsory for the degree. Usually after 5 years of bds, students write neet mds for admission in masters. Or you can work in clinics or you can set up your own clinic
