BDS

Both careers have a good scope, but what matters is your interest.
For BDS:
Dentistry has a lot of scope globally inclusive India. The thing is that what are you going to do with BDS later?
The only thing you need to have is good reputed the institution with a high calibre staff (as in private colleges) and good patient input in the institute (as in government colleges).
If you have a hunger to learn the skills then the limit .sky limit.
If you are opening a clinic, just read this Adarsh Padiyar's answer to How much can a fresher dentist earn in India? Is it true that dentists don't have a future?
Well, you can go abroad as well to pursue higher education or else you can give exams prescribed by the country you want to go to and continue your practice. This affair can be a bit expensive and gruelling.
So if you want to settle in the USA for whatever reason there are few states which allow Master's degree for international dentists. But to get into those programmes there is no known criteria and also you have to go to every state dental association website then to every university website and check out the programmes.
Even after that, those dentists will be allowed to work only in certain states.
If you are looking to go for just studies and then return to India, a lot of universities have programmes like esthetic dentistry and implant dentistry but you will not get a license to practice there in the USA.
For BPT:

Hi Madhu,
The basic requirement to practice medical cosmetology is a medical degree from any reputed medical college. But dermatologists, physicians, dentists with a Diploma or Masters degree in dermatology, may also practice medical cosmetology. Domain knowledge in science is essential as they work on skin, muscles, tissues and veins/ arteries. To perform an advanced cosmetic treatment, a degree in medicine is a must.
After completing an MBBS degree, candidates may undergo a training/ certification programme in order to become a specialist or a trainer.
Indian medical colleges, largely, do not offer these fellowship/ certificate programmes. The only institute that offers a 12-week certificate course in clinical cosmetology is the Indian Institute of Cosmetology in Mumbai.
