Mouth Health and Tobacco

　The mouth is the first organ that suffers from tobacco damage. Smoking causes the gingival of the front teeth to become darkened and melanin pigmentation (Fig. 1). Even if you quit smoking, it will take several years to go out. A cigarette tar (tar) also makes it easier to attach to the back of the teeth (Fig. 2) It is not good for beauty.
　In addition to tobacco smell, the smell of periodontal disease and dirt on the surface of the tongue (black tongue), the smell of sputum in the throat and bronchi are mixed, and emits a strong breath.
Carbon monoxide exceeding the indoor environmental standard value (10 ppm) can be detected in the exhaled breath, which poses a threat of seizures.

　Smokers are 2 to 8 times more likely to have periodontal disease than those who do not smoke. It is called "smoking-related periodontal disease" and smoking cessation is essential. Yokohama City Periodontal Disease health check-up results also indicate that smokers have more serious periodontal disease (Table 1).

(Table 1) H23 Yokohama City Periodontal Disease Test

　The three major harmful substances of tobacco are tar, nicotine, and carbon monoxide. Malicious periodontal disease bacteria in the periodontal pocket (groove between teeth and gums) dislike oxygen (anaerobic bacteria), so nicotine has poor blood flow due to vascular contraction and poor blood flow, and the combination of carbon monoxide and hemoglobin reduces oxygen. And increase momentum. Even if you brush your teeth, damage will progress from inside the periodontal tissue.
　Heavy smokers make the surface of the gingival hardening (Fig. 3), the bones supporting the teeth are significantly absorbed and losing a lot of teeth. Signs of inflammation such as bleeding and redness are difficult to appear, so the discovery of periodontal disease is delayed and becomes more severe without notice. Periodontal disease is common in the upper jaw and molars because high-temperature tobacco smoke of about 700 ° C directly hits the inside of the upper jaw and molar. It reduces saliva secretion, plaque (clots of living bacteria) and tartartar are easily attached, and reduces antibodies that fight pathogens in saliva are reduced, making it more susceptible to periodontal disease and cavity.

The healing effect is also poor, and the antibacterial effect is also low.

Blood flow disorders and inflammation in tissues around the implant (implant perfume), and the jaw bones may melt and fall off without supporting the implant (Fig. 4).

　Tobacco contains carcinogens, and smokers take in carcinogens on a daily basis. It is said that cancer in the mouth and pharyngeal cancer is three times more likely to occur than those who do not smoke (Fig. 5).

　Even though tobacco is the biggest risk factor for periodontal disease, its recognition is low in Yokohama City. According to the results of the "Public Awareness Survey" conducted every three years in Health and Social Welfare Bureau, 24.7% in 2005, 27.3% in 2008, and 24.1% in 2011.

　The effect of smoking cessation is obvious, and the blood flow of the gums recovers normally in days to weeks. Smoking smoking is the most effective means of preventing and treating oral diseases, including periodontal disease. Why don't you get back a spilling smile when you quit smoking!
