Yes, you can add BDS (Bachelor of Dental Surgery) colleges in the second round of All India Quota (AIQ) NEET counseling if you did not secure an MBBS seat in the first round. The counseling process allows you to modify and update your choices for the second round. If you are not allotted a seat in the first round or if you are dissatisfied with the allotted seat, you can participate in the second round, where you can add, remove, or reorder your choices, including selecting BDS colleges.

The second round is an opportunity to consider other options like BDS if your preferred MBBS seats are not available. Ensure that you carefully review the available BDS colleges and select the ones that match your preferences. It's important to stay updated on the counseling schedule and guidelines provided by the Medical Counselling Committee (MCC) to ensure you make informed decisions during this process. Keep in mind that the choices you make in the second round will be final, so choose wisely based on your career goals and preferences.
