A big NO to this myth!!!
Rather scaling in periodic intervals helps to maintain a good health of the entire dentition.
Firstly, let's us know how the teeth stay there in the oral cavity...
The underlying bone of the jaws give a housing to a tooth and the overlying gum wraps the tooth all around so that this housing gets the necessary protection. Now, if there is accumulation of residual food debris around the tooth-gum junction it gets calcified after a few days and starts building the aweful yellow to brown color deposit in the gum line. This deposit is called 'calculus' and it keeps on growing at the cost of your gum. Eventually the underlying bone gets infected and starts decaying. This is manifested by bleeding gum, fowl smell and may be the mobility of the teeth of that site. This infection can invite a few changes in the function of your different organs like pancreas, heart, blood vessel etc.
So it is needless to say, you should (rather must) keep an eye to this calculus and get it cleaned whenever you see it.
This cleaning of calculus is termed as SCALING. It can be of different types depending upon the nature of deposit and the loss it has created in the underlying structures.
After scaling you may find the teeth as larger than before or some spaces in between but these are due to the loss already created by the deposit not the procedure. You need to take care of these spaces by brushing as instructed and periodical follow up. It is said that longer teeth are better than the teeth no longer.
Thus it can be concluded that the scaling doesn't harm the teeth at all, rather timely and periodical scaling saves the teeth along with some other organs of the body.
