Studies show that smoking can have a negative impact on gingivitis and periodontal disease. Case studies have shown that smoking is a risk factor for loss of attachment of the gingiva and bone loss in adult periodontitis.
Smokers also run an increased risk of developing refractory periodontitis.
Refractory periodontitis is a pesky type of periodontitis that continues to progress despite aggressive therapy. The negative influences of smoking on the periodontium are unclear. Some believe this phenomenon can be explained by the altered immunological and inflammatory responses to the bacteria. The smoke may also change metabolism in the connective tissue. In addition, patients with generalized early onset periodontitis who smoke are more at risk for attachment loss than in non-smokers.
