Tackling Singapore’s Silent Epidemic of Gum Disease

With up to 90% of adults affected,periodontal disease remains one ofSingapore’s most widespread yet underrecognisedhealth issues. Dr Koh ChuGuan, senior consultant in periodonticsat the National Dental Centre Singapore,discusses the key drivers, barriers toearly care and the role of prevention inimproving outcomes.

Periodontal disease affects the vast majority of adult Singaporeans, yet gum health is often overlooked as a public health concern. According to the National Adult Oral Health Survey conducted in 2019 and reported in 2024, the prevalence is strikingly high — a trend that, according to Dr Koh Chu Guan, is driven by a combination of behavioural, medical and systemic factors.

A primary contributor is inadequate plaque control. As Dr Koh explains, bacterial plaque accumulation on tooth surfaces is the main cause of periodontal disease, making effective daily oral hygiene essential. However, inconsistent or ineffective toothbrushing, limited use of interdental cleaning methods such as flossing, and an over-reliance on professional scaling instead of daily maintenance continue to undermine prevention efforts.

Limited awareness also plays a significant role. Early-stage gum disease is often painless, leading many individuals to overlook warning signs such as bleeding during brushing. “Many patients have little knowledge about gum disease and its impact on daily life,” Dr Koh noted, adding that public education tends to focus more on dental caries than on periodontal conditions.

Lifestyle and systemic health factors further compound the issue. Smoking and vaping are strongly associated with more severe periodontal disease and can impair healing following treatment. In addition, poorly controlled diabetes increases susceptibility and disease severity. Orthodontic appliances and restorative dental work may also make oral hygiene more challenging, contributing to greater plaque accumulation and gum inflammation.

Despite Singapore’s accessibility to dental services, regular attendance remains inconsistent. Busy lifestyles, combined with limited awareness of the consequences of gum disease, often result in delayed care. Dental anxiety and fear of discomfort may also discourage patients from seeking regular check-ups.

Misconceptions surrounding gum disease continue to present significant barriers. Common beliefs — such as bleeding gums being normal, gum recession being part of ageing, or scaling causing loosening of teeth — can delay timely intervention. There is also a perception that dental conditions are less urgent than other medical concerns, as they are not typically viewed as life-threatening. Yet, as Dr Koh emphasises, periodontal disease is largely preventable, and early intervention can help avoid gum recession and tooth loss while reducing the need for more complex and costly treatment later.

Advances in periodontal care are nevertheless improving clinical outcomes. Enhanced instrumentation, adjunctive therapies such as systemic and localised antibiotics, refined surgical techniques, and the use of regenerative materials have made the management of advanced disease more predictable. Minimally invasive approaches are also increasingly adopted, improving patient comfort and recovery.

However, prevention and early detection remain the most effective strategies. Regular dental visits, periodontal screening and professional cleaning are critical components of maintaining gum health, alongside patient education and consistent oral hygiene practices.

General practitioners — both medical and dental — are well placed to support earlier detection. As Dr Koh highlights, medical practitioners, who often see patients more frequently than dentists, can incorporate simple oral checks into routine consultations, identifying signs such as gum redness, bleeding or loose teeth. They can also flag highrisk individuals — including smokers, patients with poorly controlled diabetes, and those on medications associated with gum enlargement or dry mouth — and refer them for dental evaluation.

Dental practitioners, meanwhile, play a key role through routine periodontal assessments, patient education and timely referral of advanced cases to specialists. The inclusion of oral health therapists within dental practices can further strengthen prevention and early-stage management by supporting patient education and engagement.

Raising patient awareness remains central to improving outcomes. Clear communication about the causes, progression and consequences of gum disease can encourage individuals to take a more proactive approach to their oral health. Educational materials such as charts, videos and brochures in clinics can also help reinforce understanding and prompt earlier treatment-seeking behaviour.

As Singapore continues to prioritise preventive healthcare, addressing the widespread prevalence of gum disease will require a coordinated effort across both medical and dental communities. As Dr Koh underscores, shifting from a late-treatment model to one focused on prevention and early detection is key to improving long-term oral health outcomes.
