Smoking causes dental disease and can cause blindness.

Dr. Vu Thi Diu, Deputy Head of the Respiratory Department, 19-8 Hospital, said that smoking causes yellow teeth because cigarettes contain tar, a chemical that turns teeth pale yellow.

This tar is difficult to clean with regular brushing and often forms permanent stains on smokers' teeth. In addition, when smoking, cigarette smoke will destroy beneficial bacteria in the mouth, increase the amount of saliva secreted, which is the leading cause of tartar formation.

Smoking also greatly affects eyesight and can cause blindness.

In addition, according to Dr. Diu, smoking also causes bad breath. Smoking addiction can lead to very strong and persistent breath odor that is difficult to eliminate. In addition to destroying beneficial bacteria in the mouth, smoking also causes digestive problems, sore throats, and chemical buildup in the oral cavity (diseased throats and stomachs are one of the main causes of bad breath, in addition to poor oral hygiene). Smoking creates favorable conditions for fungi to grow in the oral cavity.

The Deputy Head of the Respiratory Department also said that smoking not only affects the lungs, but also greatly affects vision and can cause blindness. Smoking increases the risk of cataracts, macular degeneration (normal age-related damage), and optic nerve damage.

Smoking accelerates the aging process, causing premature wrinkles (especially around the eyes and lips), age spots, puffy eyes, dull, dry, lifeless skin. “This is because the chemicals present in cigarettes cause the capillaries under your skin to constrict, restricting blood flow to your skin. The lack of blood and oxygen makes your skin look dry and wrinkled. Over time, this leads to permanent damage to connective fibers such as elastin and collagen, the structures that keep the skin firm and smooth – leading to permanent wrinkles and premature aging,” said Dr. Diu.
