Risk Factors For Gingivitis and Periodontitis
It is well established that the main cause of gingivitis, or periodontal disease, is bacterial plaque. But not everyone responds the same to the same bacterial infection. There are many factors that can contribute to making someone more or less susceptible to the progression of periodontitis. These factors are called risk factors. They can increase the risk, severity, and speed at which the disease develops. Some risk factors can be modified. If they are, gum disease and tissue destruction can be controlled and maybe even prevented with periodontal treatment.
There are several factors that can put individuals at greater risk for gingivitis or periodontal disease.
1. Poor Oral Hygiene: The bacterial plaque that continuously forms on the teeth is the main cause of periodontal infections. Without bacterial plaque there cannot be periodontitis. But as the amount of plaque increases, so does the risk for the disease. There is a shift in the bacterial population of plaque from one that is compatible with health, to one that is responsible for the disease. The best way to help control or prevent the progression of periodontal diseases is to follow a diligent plaque control program that includes daily brushing and flossing.
2. Crowded Teeth: Crowded teeth can contribute to plaque retention and interfere with oral hygiene. If this becomes a problem, it may be necessary to reshape the teeth or move them to a better position with the use of dental appliances or braces.
3. Poor Fitting Dentures, Fillings, or Crowns: These factors also may contribute to plaque retention and interfere with oral hygiene methods. If this is the case, the restorations may need to be reshaped, polished, or even replaced.
4. Occlusion (the way the teeth bite or come together): The forces created by an unbalanced bite, by clenching, or by grinding of the teeth, can accelerate the progression of bone destruction and periodontal disease. These forces can also contribute to excessive wear of the teeth, fractures, temporomandibular joint (TMJ) problems, or root canal problems. People who clench or grind their teeth may not be conscious of it, but may experience sore jaw muscles, TMJ problems, headaches, and neck or shoulder pain. Most people are more susceptible to clenching or grinding during periods of high stress. These habits can be controlled and treated with specially made dental appliances (night guards), braces, reshaping of the biting surfaces of the teeth, exercises, medications, or a combination of the above.
5. Tobacco: People who smoke or chew tobacco are more likely to have periodontitis. They also are more likely to have a poorer and slower response to periodontal treatment. The risk of acquiring periodontal disease decreases after smoking cessation and former smokers and non-smokers respond the same to treatment from a periodontist. Smoking cessation is beneficial to periodontal and overall health.
6. Poor Nutrition: Although periodontal disease is not caused by nutritional deficiency, a diet low in nutrients can diminish the effectiveness of the body's immune system. This reduces the resistance to infections such as periodontitis. To aid in the body's capacity to fight infections, maintain a well-balanced diet and avoid fad diets that exclude entire food groups and limit nutrients.
7. Stress: Stress reduces the immune response and makes it hard for the body to fight infection. A study has shown that people who are under financial stress and have poor coping ability have a two-fold increase in the incidence of periodontal disease.
8. Pregnancy and Female Hormonal Changes: The hormonal changes that occur during pregnancy, puberty, and menstruation can make the gums more sensitive to bacterial plaque and increase the risk for periodontal disease. Pre-existing periodontal problems can become more severe if plaque is not controlled. So an efficient and consistent plaque control program is essential in maintaining periodontal health through pregnancy and all stages of life.
9. Systemic Diseases: Certain systemic (general body) diseases, such as AIDS and diabetes, may decrease the body's ability to fight infection and can result in more severe periodontal disease. Always keep your dental care provider informed of changes in medical status.
10. Medication: Drugs such as birth control pills, immunosuppressants, anti-depressants, and some heart medications can also increase the risk for periodontal disease. Patients should inform their dental care provider of any changes in the medications that they may be taking.
11. Genetics: Up to 30% of the population may have a gene that is linked with an increased susceptibility to periodontal disease. Although genetics is not modifiable, knowing one's genetic profile puts individuals in a proactive position regarding dental health. Through proper home care, periodontal maintenance visits, modification of known risk factors, and early intervention, individuals have an excellent chance of keeping their teeth for a lifetime.

Smoking and Gum Disease
The systemic risks of tobacco use are well known. Tobacco use can increase the risk for cancer, lung disease, and heart disease. But whether you smoke, dip, or chew tobacco, it also affects the oral cavity in a variety of ways. It contributes to oral cancer, stains the teeth, and contributes to tartar deposits, bad breath, and a loss of taste and smell.
Tobacco use causes inflammation of the soft tissues of the mouth, ulcers, recession, and other oral lesions. Tobacco users are two times more likely to develop periodontitis, and ten times more likely to develop acute necrotizing ulcerative gingivitis (ANUG). They also are more likely to lose teeth than those who don't smoke. Smoking is the number one most significant risk factor in the development and progression of periodontal disease.
Tobacco smoking causes periodontal bone loss that is not related to the amount of gum inflammation or plaque accumulation. Although the periodontal disease may be advanced, the classical signs of gum inflammation (redness, bleeding gums, etc.) are not usually as evident in tobacco smokers. Thus, prevention and early detection are more difficult.
Tobacco smoking has a direct effect on the oral tissues and it can alter the immune response. Although smokers do benefit from periodontal treatment, the healing is often delayed and the results are less predictable. In addition, the success rates of periodontal and implant treatment are reduced in people who use tobacco products. The amount of complications is related to the amount of daily tobacco exposure, and the number of years the person has been exposed.
The use of tobacco products can increase the risk of periodontal disease:
1. It weakens the immune system: Tobacco products suppress the body's ability to fight infection. Carbon monoxide (a major byproduct of cigarette smoke) reduces oxygen concentration and inhibits the movement of white blood cells. This reduces the capacity of the white blood cells to fight bacteria (including the bacteria that cause periodontal disease), and delays healing.
2. It masks signs of infection: Tobacco reduces the ability of blood vessels to carry infection fighting cells, nutrients, and oxygen to the tissues. As a result, the typical signs of periodontal disease (redness, swelling, and bleeding of the gums) are masked. People who smoke may have periodontal disease that is harder to diagnose.
3. It increases calculus formation: Smoking can cause more calculus (tartar) accumulation that if not removed promptly can lead to more plaque build-up and periodontal disease.
4. It reduces healing: Nicotine and other chemicals can be absorbed directly by the root surfaces of the teeth and reduce the ability of cells to reattach to the root surface during healing.
Besides the obvious health benefits of discontinuing tobacco use, quitting can also reduce the risk of oral cancer and the detrimental effects of tobacco on the gums and bone that support the teeth. In addition, another incentive to stop smoking is that former smokers respond similarly to never smokers to periodontal treatment.
Because there is a physical and psychological addiction to tobacco, quitting can be very difficult. But millions of Americans quit smoking every year. There are aids available that reduce the craving for tobacco. These include the use of systemic medications, the nicotine patch, the nicotine gum, the nicotine inhaler, and the nasal spray. See your dentist or physician for aid in stopping tobacco use.
