Hello Aspirant. You mentioned you expect to score 200 out of 720 in NEET UG 2021. Based on your marks, your overall percentile ends up around 63.04 - 63.64 and your AIR may end up somewhere around 562264 - 637414 considering difficulty of the paper to be moderate. As you didn't mention your caste, I assume you belong to General category.

Before answering your question, you should know that your expected score is not up to the mark to get admission to MBBS at top Government or Private medical institutes (Govt. seats). Even if you get chance to opt for BDS, there are very few Private dental institutes in India where you may get chance vis Government quota.

If you score 200 then you may get chances at few dental institutes such as:

1. Manav Rachna Dental College [MRDC] (2019 Cutoff - 639607)
2. Sathyabama Institute of Science and Technology (2019 Cutoff - 645376)
3. BVDU Dental College And Hospital, Navi Mumbai (2019 Cutoff - 647367)
4. KLE Vishwanath Katti Institute of Dental Sciences (2019 Cutoff - 656396)
5. Sharad Pawar Dental College And Hospital, Wardha (2019 Cutoff - 665424)
