You will need to personally visit the dentist as charges depend upon the case as well as the practice (clinic). Scaling (cleaning) ranges from Rs 700 to 5000. Sometimes if gums are infected, certain areas may need further treatment like flap surgery or curretage, which will be charged separately. Bleaching or whitening is in the range of Rs 4000 to 12000 depending on the extent (upper/ lower teeth) and number of sittings required.
