Hello sir.   the cost of teeth cleaning starts from Rs. 800.. And the charges varies according to amount of deposits in your teeth and also in different clinics and in different areas.. Teeth cleaning is a basic procedure... You won't undergo any problem because of this.. it is mandatory to do teeth cleaning once in 6 months

Cleaning 1500-2000rs, other treatments needs to be diagnosed and then evaluated accordingly

Scaling and polishing charges will be dependent on the amount of calculus or stains tat are present....it can be anywhere between 700-2000/. There are no disadvantages of getting it done. There might be slight sensitivity for a couple of days post scaling which can be easily managed.

Cost varies from 800-2000 depending on the clinic. There may be a slight sensitivity in your teeth after scaling but will resolve on its own if it happens
