U can go for scaling and bleaching done but yes u HV to visit dentist

Hi Nice that you are planning to quit gutka. You can go for scaling and polishing to remove gutka stains. After removal of gutka stains,you can go for teeth bleaching/ whitening.

For white teeth go for scaling.Quit gutka as soon as possible chew substitute of that chewing gum n something else..

Unless you quit the habit further stain accumulation will happen post cleaning your tooth.

Sir please visit a dentist nearby because until n unless we see the condition of your teeth, we can't suggest what exactly is to be done. Because cleaning your teeth will definitely be required to remove the stains but it also depends on the extent of stains. You may also require other treatment options if you want to get it white like initial like bleaching, etc. But that can be advised only on the basis of requirement. So please visit the dentist and he/she may advise you the best treatment possible.
