Hey Khushboo,
BDS is indeed a good field but it depends on your interest if you can become successful. As far as I know BHU is one of the best universities in India and has a very good faculty for BDS.
With just a BDS degree you won't get a lot of salary. You need to do some specialisation after your BDS for more field work. Then you can open your own clinic or join some good hospital. Your salary will be between 5-10lakhs on an average and if you become a really good dentist then the salary will surely hike up.
I hope this helps, good luck!
