It’s common knowledge that smoking has many detrimental effects on general health, but less is known about the harm that it inflicts upon the mouth and teeth. The 7 most important side-effects of smoking are as follows:1. Yellow Tooth: Yellow tooth is caused by nicotine and sediments in the tobacco, which cause the teeth to become yellow or even brown in a very short time. This, however, is only the beginning.2. Gum disease and tooth loss: Smoking cigarettes negatively impacts periodontal connection and the alveolar bone and makes them very susceptible to infection, increasing the tooth loss probability.3. Oral Bacterial Growth: Cigarette smoke increases bacterial plaque accumulation around the teeth and intensifies tooth decay and periodontal tissue disease.4. Tartar: Also classified as dental calculus or bacterial plaque, it is a permanent bacterial source that creates a very unpleasant appearance for the person’s teeth.5. Tooth Cancer: The chemicals in the cigarette smoke are all cancerogenic and change the chemical mixture of the saliva in a way that makes it cancerous. Two of the three dental cancers are caused by smoking.6. Bad Breath: It is caused by the sedimentation of cigarette smoke particles in the mouth, throat, and lungs.7. Mucosal patches in the mouth: After some time, white or gray patches appear on the mucosa of the tongue, cheek, or the palate due to the constant stimulation or irritation of the mucosa by smoking. These patches, which are called leukoplakia, are considered suspicious and precancerous in many dentistry resources and should be monitored.
