Hey buddy! No need to run up to the fear of cancer because of pigmentation. Smoking causes excessive melanin production in the gums. Melanin is a pigment present in skin normally; it gives the respective color to our skin. When there is excessive melanin production in the gums you see dark pigmentation. This excessive production may be due to habits like smoking or even due to hereditary factors. Just get yourself examined by a qualified dentist, he'll do the clinical examination and help you understand the problem and the solution. Solution includes quitting of the habit and also depigmentation if required. Take care and don't worry!

Hello there.  I can understand your concern.  No. Blackened gums is not cancer. It is staining due to smoking. Smoking does however, cause cancer. It would be better if you quit it completely. Have a healthy diet, exercise daily and drink plenty of water. Best regards. Dr. Anil kumar jain. Bangalore.
