Dear Swikriti, you haven't mentioned your category. Neverthless, in 2018, 3 Government Dental Colleges in Karnataka gave admissions to candidares with NEET scores 303, 326, 347. However cut off changes every year. It depends on various factors like No. of sears available, no. of candidates appearing for the exam, difficulty of the exam, category of the candidate and top NEET score. So what might be a score that landed a medical seat might not be the case this year. But if your category is anyother than General Category, with 350 as a score you have a fair chance of getting a Dental seat. But if you belong to General Category, it should be 400 and above.
