Hello aspirant!
Hope you are doing well.

See these both are very different courses and different subjects.

In BDS+ MDS you are studying about dentistry and in Msc Anesthesiology you are studying about anesthesia and related things.
If you want to add a Doctor in your name early then you should go with Bds.
BDS (Bachelor of Dental Surgery) is a 5-years undergraduate program. .The 5-year program involves 4 years of classroom education and 1 year of compulsory rotating internship.
And after bds you have to do Mds, it is of 2 -3 years in India. So overall it takes 7 years.

Bsc Anesthesiology is 3 year course,then Msc also 2-3 year then PHd is also a long course.
So you can see both are long duration courses

But if we talk about scope, then definitely it better for anesthesiologist as In India there is saturation of dentist . And government is also not opening new dental colleges. There are very few job vaccancies too

If you choose Bds as your career option here are some tools which will help you:
