Whether you consume roll-your-own tobacco, cigarillos, or filtered cigarettes, smoking exposes your body to over 7,000 different chemicals, of which at least 250 are known to be harmful, affecting smokers’ teeth and their oral health. And among them, approximately 70 can cause cancer.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

It is an alkaloid naturally present in the tobacco plant. It is the primary psychoactive compound in tobacco, responsible for smokers’ dependence. Among other effects, this substance stimulates the central nervous system, accelerates heart rate, and increases blood pressure. It also promotes the risk of blood clot formation and contributes to the hardening of arteries (atherosclerosis).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Tars are produced during tobacco combustion. When inhaled, they contribute to the obstruction and inflammation of the lungs, thus facilitating the onset of chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD), asthma, or emphysema. Furthermore, they contain carcinogenic substances that promote the development of lung, throat, and mouth cancers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Produced during tobacco combustion, carbon monoxide is a toxic gas that binds to hemoglobin in the blood more efficiently than oxygen. By taking its place, it thus reduces the blood’s ability to transport oxygen to organs and tissues. This can lead to cardiovascular problems, shortness of breath, and decreased physical performance.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A cigarette contains a wide variety of substances that the human body is not meant to ingest:<\/p>

  • lead<\/li>
  • arsenic<\/li>
  • cadmium<\/li>
  • ammonia<\/li>
  • benzene<\/li>
  • formaldehyde<\/li>
  • acrolein<\/li>
  • etc.<\/li><\/ul>

    These toxic substances accumulate in tissues and can cause a wide range of serious health problems. Long-term exposure to these chemicals can cause damage to almost all organs of the body, with an increased risk of heart or respiratory diseases and various cancers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Directly exposing the smoker’s teeth, gums, and tongue to smoke containing numerous dangerous substances, smoking has a negative impact on oral health. Simply put, all aspects of oral health are affected. Smoking not only affects the appearance of your smile and your breath, but also promotes the development of potentially serious diseases within the oral cavity, including cancers. And some of these pathologies can themselves evolve into problems that impact your general health. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    The toxic compounds to which smoking exposes the mouth interfere with the proper functioning of gingival cells. By compromising cell renewal, it impairs gum health and increases the risk of oral infections. In fact, it is one of the most significant risk factors for the development of periodontal diseases, an infection of the tissues that support the teeth, which can extend to the bone. <\/p>

    People who smoke are more likely than non-smokers to suffer from:<\/p>

    • gingivitis (gum inflammation) with or without bleeding;<\/li>
    • periodontitis (deterioration of tissues and bones supporting the teeth);<\/li>
    • gum recession (recession of gingival and bone tissues covering the dental roots) potentially leading to tooth loss.<\/li><\/ul>

      Furthermore, in smokers, blood circulation in gingival tissues is less efficient, which reduces their ability to heal after an injury or surgical procedure (tooth extraction, abscess drainage, bone grafting, dental implant placement, etc.). Consequently, dental treatments more often result in failure in smokers than in non-smokers. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

      Due to the tar and nicotine they regularly inhale, people who smoke often have yellow teeth and dental stains. Although nicotine is colorless at its base, it yellows when it comes into contact with oxygen. For its part, tar is naturally dark and easily accumulates on tooth enamel, causing stubborn yellow to brown stains. Thus, a smoker’s smile is often not their most appealing feature. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      Cigarette smoke disrupts the balance of oral flora. It depletes the natural oral microbiota and promotes the growth of pathogenic bacteria that contribute to cavity formation. Furthermore, smoking dries out the mouth by reducing saliva production. The oral cavity therefore does not benefit from as effective cleaning as it should, nor from the natural protection against cavities that saliva provides. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      By promoting periodontal diseases, smoking leads to gum recession. This means that the smoker’s gums gradually recede and the bone tissue supporting the teeth diminishes. The teeth then become more mobile and may eventually fall out if no action is taken. While this problem certainly harms the aesthetics of the smile, it primarily prevents proper chewing and hinders the pronunciation of certain syllables. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      Smoking is a major risk factor in the development of oral cancer. Smokers are six times more likely than non-smokers to develop oral cancers. They alone account for 75% of oral cancer cases. Indeed, the chemical substances present in tobacco smoke damage the DNA of oral cells. They thus increase the risk of mutation and the development of cancerous cells. <\/p>

      Symptoms that may suggest this type of cancer include:<\/p>
