Hello,
Your chances are very low to fetch a government BDS seat with this score,even with OBC category. Since, you belong to Karnataka state there the cutoff goes very high for MBBS and BDS seats. Even if you have Karnataka state domicile, it will be difficult to get a seat in government college.
You can go for private colleges with less cutoffs, if you can afford the high tution fee of the institution. But it will not worth for your career after completion of your BDS degree from private college.
You should give one more chance to yourself, by dropping one year.
Good luck! Ask if further queries.
