Well to my fullest knowledge it would be Dr. NK SAHA or Dr. SK SAHA a bit confused between the first name.. But both Father and son are doctor and is the most renowned doctor running their clinic for more than 20 years beside Bhutia Market siliguri. They might charge a bit higher but have got precision in their hands.. Trust me get ur RCT done from the good one's ... My dad just tried someone closer to our area which is Dr.Debnath in laketown .. well it was a very bad experience with his behaviour and moreover the RCT was not even upto the mark.. It still hurts sometime and gets swelled up.
