How Smoking May Affects Your Oral Health

Current study suggested that smoking suppresses the immune system, leaving gums prone to infection. In fact, research has shown that smokers were more than 50 percent more likely to develop gum disease than non-smokers. If you care enough and want to improve your oral health, here is a list of reasons for you to quit smoking.

  1. Smokers are at risks of losing their teeth two times more than that of non-smokers, due to plaque and tartar build up that encourages dental decay.
  2. Smokers are two time more prone to suffer from Infected exposed roots of teeth when compared to non-smokers, due to poorer gum conditions. Exposed roots are more sensitive to hot and cold foods and beverages, making eating painful.
  3. Smoking reduces your ability to fight infection throughout the body, including in the mouth and gums.
  4. Smoking causes bad breath (and it’s much more pleasant to kiss a non-smoker!)
  5. Smoking slows your body’s ability to heal from injury or surgery (including tooth extraction and oral surgery). This makes smoker’s poor candidate for any surgical dental procedures even if the best technology and treatment is available due to possibility of impaired healing.
  6. Smoking reduces the effectiveness of gum disease treatments (periodontal treatment) that stop or delay tooth loss.
  7. Smoking can cause staining of teeth and filling restorations (Did you know studies indicate that most people consider a white, healthy smile as an indicator of youth and vigour?)
  8. Smoking can cause inflammation of the salivary gland openings on the roof of the mouth.
  9. Smoking (tobacco use) increases the risk of developing cancer.2 (According to the American Cancer Society, about 90% of people with cancer of the mouth, lips, tongue and throat use tobacco, and the risk increases with the amount smoked or chewed and the duration of the habit. Smokers are six times more likely than non-smokers to develop these cancers.)
  10. Smoking is a major risk factor for gum diseases. The prevalence and severity of periodontal attachment breaks down gets worse with higher level of smoking. Gum diseases are difficult to treat as long as you continue to smoke.
