Tobacco use is one of the greatest threats to oral health. While many people associate the damage caused by tobacco with stained teeth and bad breath, the consequences are far more serious and wide-ranging. Studies show that tobacco is responsible for numerous oral health issues, some of which may be irreversible.
Among the most common effects of tobacco are tooth discolouration, caused by nicotine and tar that deposit on the tooth surface, leaving them yellow or brown. In addition, tobacco use leads to halitosis (bad breath), as smoke dries out the mouth and reduces the flow of saliva, which is essential in combating bad breath. Another consequence is the alteration of taste, especially in long-term smokers, who often lose the ability to perceive or properly distinguish flavours such as saltiness.
Tobacco also increases the risk of periodontitis, a disease that affects the supporting structures of the teeth. Nicotine reduces blood flow to the gums, which can mask the symptoms of periodontitis and make early diagnosis more difficult.
For smokers, maintaining good oral health requires extra care. It is essential to brush teeth regularly, use dental floss, and carry out more thorough tongue cleaning. Regular visits to the dentist are also crucial.
Although many believe that electronic cigarettes are a healthier alternative to traditional tobacco, this is not the case. Despite not producing smoke, e-cigarettes contain nicotine, which negatively affects gum health, increases the risk of periodontitis, and alters the pH level of the mouth, encouraging the development of cavities and other dental problems.
