Ultrasonic cleaning has no effect on smoking, which means that you can smoke immediately after the cleaning. However, from a health point of view, long-term smoking is not recommended. Smoking on the human lungs and other parts of the body have an impact on health, especially on the oral periodontal impact will be greater, because smokers his teeth will be deposited on the surface of the plaque, if not removed in a timely manner, this plaque on the one hand, will make the teeth black, affecting the aesthetics, and on the other hand, it is also easy to deposit bacteria, which will release toxins, which will lead to inflammation of the periodontal periodontal disease. Periodontal inflammation is a chronic invisible killer, it will make the alveolar bone gradually absorbed, so that the teeth gradually become loose, and this symptom is the whole mouth multiple teeth will gradually appear, so from the theory, although the cleaning of the teeth on the smoking is not affected, but it is still recommended to quit smoking as soon as possible.
