Hey sai!

First of all, bachelor of dentistry is the only professional field with 100% placement and after its completion , your name will be written with a prefix dr.

And i think thats the biggest use of bds course . You can work as dental specialist , assistant , dental lab technician ,dental hygienist  , professor. 

The initial salary ,a person gets after BDS course is 2-3 lacs but after having enough experience , he can get an average package of 4-6 lacs
