Gingivitis - Everything You Need To Know
Gingivitis is the most common periodontal disease, affecting 90% of the population. It is an infection of the gums caused by bacteria that form plaque.
In small amounts (when it is newly formed), plaque is invisible and relatively harmless. But when left to accumulate, it increases in volume and the proportion of harmful bacteria grows. These gingivitis bacteria release toxins that result in inflammation of the gum tissue and bad breath.
Eventually, the plaque hardens and forms hard deposits called calculus or tartar. If not properly treated, gingivitis may progress to periodontitis, a periodontal disease in which there is loss of the bone that supports the teeth.
Signs of Gingivitis
Gingivitis can be identified by red or swollen gums. In some circumstances, the gingivitis can cause bleeding gums when brushing or eating, and there may be bad breath. To diagnose gingivitis, a dentist may probe gently under the gums. In healthy gums, there should not be any bleeding with this gentle probing. A bleeding gum indicates that there is gum inflammation or gingivitis.
Who's At Risk for Gingivitis?
Certain people are more susceptible to gingivitis. Stress, smoking and poor nutrition can contribute to the development of gingivitis. Certain medications such as steroids, heart medications, cancer therapy drugs, anti-epilepsy drugs, and anti-depressants also increase the risk for gingivitis.
In the presence of plaque, these medications can lead to gum overgrowth. The enlarged gums can further interfere with oral hygiene, precipitating a vicious cycle of further gum enlargement.
Changes in female hormones can also increase the vulnerability to gingivitis. Adolescent women, pregnant women and women who take hormone replacement or birth control pills also have a greater risk of developing gingivitis.
There are several systemic illnesses that are associated with gingivitis. These include
- acute leukemia
- Addison's disease
- diabetes
- hemophilia
- immunodeficiency diseases (including HIV)
The swelling and redness of the gums may be disproportional to the amount of plaque present. To prevent further complications, meticulous plaque control is critical for people with these illnesses.
Gingivitis Treatment
For gingivitis treatment, the bacterial plaque and tartar have to be removed from the surfaces of the teeth by a dentist or hygienist. Then, the factors that contribute to plaque retention have to be altered in order to facilitate oral hygiene procedures.
This can involve re-shaping existing restorations or even moving teeth with braces so that they are not crowded. Essential to the success of the gingivitis treatment is the person's ability to control plaque build-up after initial treatment. Daily brushing and flossing are key to gingivitis prevention and helps prevent bad breath.
If there is a lot of gum inflammation, if the gums are very sensitive, or if there is a lot of tartar buildup, it may be necessary to numb the gums in order to remove the buildup of bacteria underneath the gum margins. If the gum is very inflamed and swollen, it may be necessary to remove some of the excess gum tissue surgically.
Gingivitis is reversible, and with proper gingivitis treatment and maintenance, it can be controlled. However, untreated gingivitis can result in gum defects, bone loss around the teeth, and eventual tooth loss and systemic complications. The best way to prevent gingivitis is by brushing and flossing daily, and by visiting the dentist for a routine cleaning and an examination at least every six months.

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.
