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.

Periodontal Regeneration Dentistry Treatment

Periodontal regeneration means restoring the bone and supporting tissues adjacent to teeth with advanced bone loss. Frequently, periodontal regeneration treatment will prolong the use of the involved teeth. A periodontist or dentist will diagnose the problem by taking a careful medical and dental history.

The tissues adjacent to the teeth will be gently probed with a calibrated, ruler-like instrument. These measurements, together with a dental X-ray, will help determine the appropriate treatment for the involved teeth.

There are many regenerative techniques and methods. Bone purchased from bone banks has been used effectively as a regenerative material for over 30 years. This bone is procured from healthy individuals, is carefully processed, and has been proven safe. Treatment consists of carefully moving the gum tissue away from the involved teeth and removing tarter (calculus) deposits from the root surfaces.

The bony defect is gently filled with the bone bank material (allogenic bone) or other synthetic materials. The gums are then replaced around the neck of the teeth with small sutures. The sutures are removed within five to seven days, and gentle tooth brushing can resume.

Synthetic bone substitutes have been developed to simulate natural bone. These materials are safe, and may help support the involved teeth. Such substitutes are implanted through periodontal surgery. Recently, cow bone, which is carefully prepared, sterilized, and safe, has been used to repair defects next to teeth. This bone is porous, allowing bone from the patient to grow into the pores. New technologies have developed porcine (pig) proteins, which, when painted onto teeth, allow for natural regeneration of tooth cementum and bone. These materials have demonstrated early promising clinical results.

The use of barrier membranes to protect and isolate bony defects has been used for over 15 years. These are made from synthetic, non-dissolvable materials, dissolvable materials, or bovine collagen (cow collagen). Membranes are frequently used either with synthetic graft materials or with bone purchased from bone banks. Recently, proteins have been joined to synthetic bone.

This material enhances cell attachment to root surfaces and may provide an effective method for periodontal regeneration. In the future, proteins that stimulate bone formation and enhance formation of new root cementum will make periodontal regeneration a simple, effective method to save teeth with advanced disease.

The materials discussed above have been published in dental journals, are safe, and generally result in tooth retention with bone fill of the treated bony defects. Articles relating to periodontal regeneration can be researched from PubMed using the following key words: "periodontal," "regeneration," "allogenic bone," "synthetic bone grafting," and "barrier membranes."
