Thanks Dr. Karminder, really appreciate it.
I am going to shoot her an email and ask her which cleaning she did, based on the details you told me. I think she was talking about hidden residue in gums - subgingval. Now after your explanation, I don't understand why she wants me to see a dental hygienist (and that too 3 times a year) if the hygienist isn't authorised to do it.
The bill says "Scale and polish" for the services provided, so she might have just polished the teeth (that I never wanted in the first place). I am going to be quite pissed about it as she was done with me in less than 30 minutes, but charged me for 30 min - 1 hour of consultation + 30 min of cleaning. The shocking part is that they don't give a diagnosis - she didnt even give me my X-rays. Let me give her some hard time about supragingival and subgingival...
She had recommended a special anti-bacterial mouthwash Curaseptic that stops formation of plaque. I got that but it says "use for 10 days. Consult dentist if you need to continue further". Is it something I can continue using? I am basically looking for non-intervention ways where I can clean my gums myself (maybe over a long period of time).
As for filling, it was more than 5 years back. These days I sometimes feel something funny (A bit of a stretch to call it pain), but I think it is psychological since she put it in my mind. (Is it possible that she knocked off my filling while cleaning -
"ki ab to aayega hi waapas" )
Thanks again for your kind and elaborate answer.
