While many people believe periodontal disease is an adult problem, studies indicate that gingivitis (the first stage of periodontal disease) is nearly a universal problem among children and adolescents. Advanced forms of periodontal disease are more rare in children than adults, but can occur.

Chronic gingivitis is common in children. It can cause gum tissue to swell, turn red, and bleed easily. Gingivitis is preventable and treatable with a regular routine of brushing, flossing, and professional dental care. If left untreated, it can eventually advance to more serious forms of periodontal disease. Children should be helped to brush the gumline.

Localized aggressive periodontitis can affect young healthy children. It is found in teenagers and young adults and mainly affects the first molars and incisors. It is characterized by the severe loss of alveolar bone, and ironically, patients generally form very little dental plaque or calculus.

Generalized aggressive periodontitis may begin around puberty and involve the entire mouth. It is marked by inflammation of the gums and heavy accumulations of plaque and calculus. Eventually it can cause the teeth to become loose.

Conditions that make children more susceptible to periodontal disease include:

• Type I diabetes.
• Down syndrome.
• Papillon-Lefevre syndrome.

For example, in a survey of 263 Type I diabetics, 11 to 18 years of age, 10 percent had overt periodontitis.
