which has more salary? BDS or Bams
This is not specific.
This completely depend on your experience and efforts
This also depend on the hospitals and area in which you are practicing.
There are few dentists who earn lesser than an Ayurvedic doctor. While there are few ayurvedic doctor who are still struggling to earn well.
So, no one can tell you about who earns more.
Both the courses have their pros and cons.
Best of luck for your future
