Smoking is a dangerous habit that has been linked to lung cancer and other serious cardiopulmonary diseases. It also affects your oral health. In addition to discoloring your tongue, smoking causes bad breath and stains your teeth, which requires professional cleaning.
The harsh chemicals contained in tobacco smoke can lead to a dulled sense of taste and smell. Along with these cosmetic issues, smoking and the use of chewing tobacco can also lead to other more serious oral health problems.
