Hello Sheema

A score of 230+ is too low to get admission in any Government college. The cutoff for government dental colleges in Tamil Nadu goes as high as 530 to 560+
And so there are nearly no chances of yours to get admission in any BDS colleges with this score. However you can try for private colleges.
Use the college predictor tool to know your chances of admission in other colleges:
