One should keep in mine for the most part a dentist or maybe in your case an orthodontic dentist will not suggest you do something unless they feel that is what is needed. That is not to say that the first dentist you went to in India is necessarily wrong. They just might have two different opinions on how to correct the problem.
Therefore I would speak to the dentist that you are seeing now. Explain to him/her what you where told by another dentist and have him/her explain to you their reasons for the procedures they are suggesting. If you still feel that you are being talked into a procedure you do not feel you need, then get a second opinion.
Remember what you decide to do will be up to you. The more you understand the better your decision will be. Ask all the questions you need to ask until you have full understanding of the issues at hand.
I hope I have helped.
