Can smoking cause bad breath?

Yes. Tobacco causes its own type of bad breath. The only answer in this case is to stop smoking. As well as making your breath smell, smoking causes staining and loss of taste, and irritates the gums. People who smoke are more likely to suffer from gum disease and have a greater risk of developing cancer of the mouth, lung cancer and heart disease. Ask your dentist, pharmacist or healthcare professional for help with stopping smoking. If you do stop smoking, but still have bad breath, then you need to see your dental team or doctor for advice.
