Hello Somnath,

Im sorry to say that based on your marks and previous cutoff trends you do not qualify for a BDS seat in West Bengal (if you belong to the unreserved category) 

If you belong to any of the reserved categories, then you do stand a chance. I’m attaching two links here. One is for cutoffs of medical and dental colleges in West Bengal

And the other is for cutoffs from all across the country:
