My mom and I had a very bad experience with scaling. The doctor was very harsh and vigorous with her work. I have been in and out of dentists all my life, and I have history to compare with. The doctor and her assistant did a messy procedure, as blood and water were dripping down our necks. This was by far our worst experience.
A lot of care was taken by the chief doctor and all the staff during my surgery. Very friendly and reliable service.
