Dear aspirant, To be honest it's tough to get admission in any government or private Institute. You can wait for another one year or if possible can go for Management quota. You also can go for any BDS college of your state such as:

• Budhha Institute of Dental Science and Hospital, Patna
• Mithila minority Dental College and Hospital
• Sarjug Dental College and Hospital, Laheriasarai

Hope you have understood.
