Tobacco
Dried and fermented tobacco leaves produce tobacco products such as cigarettes, bidis, cigars, and kreteks. Unfortunately, many users are not able to quit due to its addictive ingredient, which is nicotine. Aside from nicotine, other chemicals contribute to the health risks such as lung cancer, chronic bronchitis, stroke, and mouth sores.
Due to the chemicals, irritants, and carcinogens or harmful substances that cause cancer, tobacco can cause mouth sores. The soft tissues are thin and sensitive and quickly sore and irritated. Another reason is the drying effects it causes on the mouth lining due to high temperature. These will lead to lesser moisture content on the soft tissue leading to mouth ulcers. Smoking tobacco can also change the acidity inside the mouth leading to worn tissue lining.
All of these effects of tobacco will lead to lesser resistance to bacterial infections. This will prompt the appearance of mouth sores and cause painful hindrances in some bodily functions.
