There might be some dental colleges, which are taking admission directly.

But in my opinion you should prepare for NEET UG entrance.

Because there is lots of opportunities in government colleges.

There is very much difference in fee of the colleges.

My advise is just try for preparation and it's depends on your state and Rank. Where you can easily get admission.

Don't do BDS from any private college.

You can try BHU and AMU also through NEET.

They are taking admission directly from NEET ranking
