professional cleaning ie scaling will solve your problem

The deposits of Calculus on the teeth and the tobacco stains can be removed by a process called as scaling. Schedule an appointment with your dentist for this as per your convenience. But it is my ethical responsibility to make you aware that the stains caused by tobacco is the least of anybody's concern. You seem educated enough to understand that tobacco is potentially more dangerous and you should quit this habit before the dangerous and Irreversible effects begin to take shape. Regards.
