Periodontal Disease Epidemiology Forecast

• According to DelveInsight’s analysis, Periodontitis remains a significant public health concern in the United States, affecting nearly 42% of adults aged 30 and older. This high prevalence highlights a substantial burden on the healthcare system. Notably, 8% of these individuals suffer from severe forms, while nearly 35% exhibit milder stages, indicating varied disease progression. The distribution reflects both the widespread nature of the condition and the need for targeted prevention and intervention strategies. 
• The presence of severe periodontitis in nearly one in thirteen adults suggests potential long-term complications, including tooth loss and systemic health effects, reinforcing the importance of early diagnosis and sustained oral healthcare efforts.
• In Italy, approximately 1 in 5 adults is affected by the most severe form of periodontal disease, which has the potential to result in tooth loss and may adversely affect chewing function, appearance, and overall quality of life as reported in the studies.
• As per the secondary analysis, in 2024, 49% of adults in Japan were affected by periodontal disease, with prevalence increasing with age. Among study participants, nearly 55% of females were diagnosed. Severe periodontal disease occurred in 3.6% of individuals, while 96.4% did not progress to this stage.
• The rising number of periodontal disease is primarily driven by the accumulation of dental plaque, heightened bacterial infection, and inadequate oral hygiene practices, indicating the critical role of preventive care in disease management.
• Changes in lifestyle habits and growing awareness of oral health are contributing to an increase in both the occurrence and diagnosis of periodontal disease. These factors are significantly shaping epidemiological trends, as improved access to dental care and heightened screening efforts contribute to a growing number of diagnosed cases, thereby amplifying the perceived public health burden of the condition.

DelveInsight’s “Periodontal Disease – Epidemiology Forecast – 2034” report delivers an in-depth understanding of periodontitis, historical and forecasted epidemiology trends in the United States, EU4 (Germany, France, Italy, Spain), the United Kingdom, and Japan.

Disease Understanding

Periodontal Disease Overview

Periodontal diseases encompass conditions affecting the periodontium—the supporting structures of the teeth—including the gingiva, alveolar bone, cementum, and periodontal ligament. While poor oral hygiene is a common contributing factor to gum disease, individual susceptibility can vary, with some people developing periodontal issues despite maintaining regular brushing and flossing routines. Gingivitis, the most common and mildest form of periodontal disease, affects up to 90% of the population. It is characterized by inflammation of the gingiva due to the accumulation of plaque—a mix of bacteria and debris—along the gum line. Importantly, gingivitis is a reversible condition when oral hygiene is improved. However, if left unmanaged, it may progress to periodontitis (periodontal disease)—a more severe, chronic, and irreversible inflammatory disease that causes destruction of the supporting tissues around the teeth.

Periodontal Disease Diagnosis

The diagnosis of periodontal disease relies on a comparative assessment against the characteristics of a healthy periodontium, which is typically marked by pale pink, stippled gingiva closely adapted to the underlying bone. Clinical evaluation involves visual inspection, periodontal probing, and radiographic assessment of alveolar bone levels. Key indicators of disease include spontaneous or easily provoked bleeding, pain, halitosis or bad taste, periodontal pocket formation, radiographic evidence of bone loss, clinical attachment loss, and eventual tooth loss. The severity of periodontal disease correlates with the depth of periodontal pockets—deeper pockets indicating more advanced disease. Dental radiographs are essential in confirming the diagnosis, with periodontitis typically presenting as alveolar bone loss adjacent to areas of deep probing depth.

Periodontal Disease Epidemiology

The periodontal disease epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by Total Prevalent Cases of Periodontal Disease, Total Diagnosed Prevalent Cases of Periodontal Disease, Severity–specific Diagnosed Prevalent Cases of Periodontal Disease, and Gender–specific Diagnosed Prevalent Cases of Periodontal Disease in the 7MM covering, the United States, EU4 countries (Germany, France, Italy, and Spain), United Kingdom, and Japan from 2020 to 2034. 

• According to the secondary analysis, cross-sectional data from the US reveal a substantial burden of periodontal conditions, with approximately 50% of the adult population currently affected by gingivitis and up to 80% having experienced some form of periodontal disease over their lifetime. These figures highlight the widespread nature of periodontal health issues and underscore the need for improved preventive strategies and public awareness.
• A study on periodontal disease stratified severity into categories such as gingivitis, mild, moderate, and advanced periodontitis. In France, findings revealed a high overall prevalence of self-reported gingival bleeding at 63.2%. The majority of individuals (58.7%) reported bleeding associated with tooth brushing, while a smaller segment (4.5%) experienced spontaneous bleeding, highlighting varying degrees of gingival inflammation within the population.
• Secondary analysis suggests a higher prevalence of periodontal disease among males compared to females in some regions, potentially reflecting gender-related differences in oral health awareness, behaviors, or biological susceptibility.

KOL Views

DelveInsight’s analysts collaborated with over 50 key opinion leaders (KOLs), conducting in-depth interviews with more than 15 experts across the 7MM. To keep pace with dynamic market trends, the team gathered first-hand insights from KOLs and subject matter experts (SMEs) through primary research, addressing data limitations and reinforcing findings from secondary research. These professionals offered valuable input on the Periodontal Disease landscape, highlighting patient behavior trends, and challenges in access to care. Contributors included experts from renowned institutions such as the National Institute of Environmental Health Sciences, Research Triangle Park, North Carolina, US, Aichi Health Promotion Foundation, Nagoya (Japan), University of Oviedo Faculty of Medicine and Health Sciences, Oviedo, Asturias, Spain, University Medical Center Mainz, Germany, University of Bradford School of Optometry and Vision Science UK, Chubu Rosai Hospital, Japan, and Toho University School of Medicine Japan, among others.

As per the KOLs from US, the disease proceeds cyclically with periods of activity and quiescence until therapeutic action is taken, or the tooth and surrounding structures are destroyed by the disease process that may result in the loss of the tooth. As periodontal disease progresses from gingivitis to periodontitis, a greater number of anaerobic organisms colonize deeper periodontal pockets

As per the KOLs from the Japan, in recent years gingival bleeding is one of the most recognizable clinical indicators of gingivitis and has been linked to systemic conditions such as otitis media/externa and asthma during adolescence. Additionally, the presence of dental calculus is strongly associated with increased rates of gingival inflammation in adolescents and young adults, as it creates a favorable environment for bacterial biofilm accumulation and initiates an inflammatory response in the adjacent gingival tissues.
