Hello, its good that you have the will to leave the habit of tobacco chewing, because no counselling or supportive therapy can help you unless and until you have the will to quit it. Stay committed to quitting the habit, cut down gradually and quit it finally. Start chewing
sugar free gum if you have urge to chew tobacco, drink plenty of water, and stay active.
And regarding the cleaning, you may go for a thorough professional cleaning from a dentist to remove the tobacco stains, plaque and tartar.
Tobacco in any form is injurious to health overall.
Wish you all the best, quit this habit, sooner the better.
