Dental Procedure For Dental Recession
Dental recession is a displacement of the gum around the teeth that results in greater tooth exposure and a longer looking tooth. As the gum that protects the root surface of the tooth is lost, not only does it create an esthetic deformity, it makes the tooth more sensitive to changes in temperature (hot and cold), touch, and to proper oral hygiene techniques. The exposed root surfaces also are more susceptible to cavities. Causes of dental recession include:
- Periodontal disease: The bacteria that cause gingivitis can release toxins that injure the gum tissues and create gum recession. Once the gum is affected by gingivitis (see article "Gingivitis"), it is even more susceptible to further dental recession and bone loss. So if the gum is red, swollen, or bleeds when probed, it is more likely to continue receding. Eventually, there may not be enough healthy gum and bone left to protect the tooth and the tooth may need to be removed. If there is less than 2 mm of healthy gum in an area of recession, a dentist may recommend a gum graft to help prevent further receding gums and help protect the tooth.
- Trauma: Medium or hard bristle toothbrushes, brushing too hard, or brushing inappropriately can damage the teeth and the gums. It is very important to use a soft bristle toothbrush when cleaning the teeth, and to follow proper technique. Mechanical trauma to the gums also can be caused by improperly fitting dental restorations or dentures. Fillings that are rough or dentures that are loose or poorly designed can injure the gums and cause them to recede.
Gums also may recede as a result of orthodontic treatment or from manipulation during restorative procedures. To prevent this from occurring, a dentist may recommend gum grafting before orthodontics or restorative treatment.
Gum grafts are indicated if an individual has root sensitivity to touch or temperature changes, if new restorative work will be done in the area of the dental recession, if the roots are susceptible to cavities, or if an individual is having problems following proper plaque control procedures. In addition, gum grafts are cosmetic periodontal procedures that can be performed to enhance smiles if recession has created esthetic problems such as long teeth or exposed roots.

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.
