Quick answer. Gum (periodontal) disease is extremely common in Singapore, affecting the majority of adults. Its early stage, gingivitis, causes red, swollen, bleeding gums and is reversible with professional cleaning and good oral hygiene. If untreated it can progress to periodontitis, which destroys the bone supporting your teeth, causes gum recession and loose teeth, and is the leading cause of adult tooth loss; periodontitis can be controlled but generally not reversed. Smoking and diabetes sharply raise the risk. Treatment ranges from scaling and polishing to deep cleaning (scaling and root planing) and, in advanced cases, gum surgery. Routine dental care such as scaling is not MediSave-claimable, but CHAS subsidies and subsidised polyclinic/NDCS care help eligible patients. See a dentist if your gums bleed when you brush.

Gum disease is one of the most widespread health conditions in Singapore, with national surveys showing that most adults have some degree of it. It often develops quietly and painlessly, so many people only notice a problem once teeth become loose. The good news is that the early stage is reversible, and even advanced gum disease can usually be controlled with the right treatment and daily care. This guide explains the two stages, the warning signs, how it is treated, what it costs and how subsidies work in Singapore.
At a glance
| Stage | Signs | Treatment |
|---|---|---|
| Healthy gums | Firm, pink gums; no bleeding | Brush twice daily, clean between teeth, 6-monthly check-up and scaling |
| Gingivitis (early, reversible) | Red, swollen, tender gums that bleed when brushing or flossing | Professional scaling and polishing plus improved daily oral hygiene |
| Early to moderate periodontitis | Bleeding, bad breath, gum pockets forming, slight recession | Scaling and root planing (deep cleaning); smoking cessation; closer monitoring |
| Advanced periodontitis (controllable, not reversible) | Receding gums, deep pockets, loose or shifting teeth, possible tooth loss | Gum surgery, specialist periodontal care, ongoing maintenance |
| Tooth loss stage | Lost or extracted teeth from bone destruction | Stabilise remaining teeth; replacement options (e.g. dentures, implants) |
How common is gum disease in Singapore?
Gum disease is the norm rather than the exception among Singaporean adults. A large Health Promotion Board study found that nearly 85% of adults had mild to moderately severe periodontal disease, and a 2019 nationally representative oral health survey reported an overall periodontal disease prevalence of around 77% among adults. The risk rises steadily with age, and periodontitis remains a major cause of tooth loss in older Singaporeans. Because the early stage causes few or no symptoms, a large proportion of people are unaware they have it.
The two stages: gingivitis vs periodontitis
Gingivitis is the early stage. Plaque (a sticky film of bacteria) builds up along the gum line and inflames the gums, making them red, swollen, tender and prone to bleeding when you brush or floss. Crucially, gingivitis is reversible – with a professional clean and good daily oral hygiene, the gums can return to full health because the bone and supporting tissues are not yet damaged.
Periodontitis is the advanced stage. The infection spreads below the gum line and destroys the bone and fibres that anchor your teeth. This leads to gum recession, deep pockets around the teeth, persistent bad breath, and eventually loose teeth and tooth loss – periodontitis is the leading cause of tooth loss in adults. Once bone is lost it does not grow back on its own, so periodontitis is generally not reversible; however, with treatment it can be controlled and stabilised to prevent further damage.
Symptoms and causes
Gum disease is often painless until it is advanced, which is why regular check-ups matter. Watch for:
- Gums that bleed when you brush or floss
- Red, swollen or tender gums
- Persistent bad breath or a bad taste
- Receding gums or teeth that look longer
- Loose or shifting teeth, or a change in your bite
The root cause is plaque from inadequate oral hygiene. Key risk factors that make it worse include:
- Smoking – one of the strongest risk factors; it also masks bleeding and makes treatment less effective
- Diabetes – there is a two-way link: poorly controlled diabetes worsens gum disease, and gum disease can make blood sugar harder to control
- Increasing age, genetics/family history, and poorly fitting fillings or crowns that trap plaque
The link to your general health
Gum disease is not just a dental problem. The clearest connection is with diabetes: the two conditions feed each other, so treating gum disease can support better blood-sugar control, and good diabetes control improves gum health. Periodontal disease has also been associated with heart (cardiovascular) disease and other systemic conditions, reflecting the way chronic gum inflammation can affect the rest of the body. Managing your gums is therefore part of looking after your overall health.
Treatment options
Treatment depends on the stage:
- Gingivitis: professional scaling and polishing to remove plaque and tartar, combined with improved daily oral hygiene, is usually enough to reverse it.
- Periodontitis: deeper non-surgical cleaning called scaling and root planing (deep cleaning) removes bacteria and tartar from below the gum line and smooths the root surfaces. This may be done over several visits, sometimes under local anaesthetic.
- Advanced periodontitis: gum (periodontal) surgery may be needed to clean deep pockets or regenerate lost tissue, often by a periodontist. In Singapore, non-surgical periodontal treatment and specialist surgery are offered at the National Dental Centre Singapore (NDCS) and other centres.
No treatment works without excellent daily oral hygiene: brush twice a day with fluoride toothpaste and clean between your teeth daily with floss or interdental brushes. Stopping smoking is one of the most effective things you can do to halt the disease.
Cost, CHAS subsidies and MediSave
Routine dental care in Singapore is treated differently from medical care. MediSave generally cannot be used for routine treatments such as scaling, polishing, fillings, simple extractions and dentures – MediSave only applies to certain surgical procedures under MOH’s Table of Surgical Procedures, which can include gum surgery and surgical wisdom-tooth removal (subject to claim limits).
For everyday gum care, help comes mainly through subsidies:
- CHAS subsidies at participating dental clinics help eligible cardholders with basic procedures like scaling and polishing. Subsidy amounts differ by card tier (Blue, Orange, Merdeka Generation and Pioneer Generation), are capped per visit and limited to a set number of times per year, so you pay any difference above the cap.
- Polyclinics and the National Dental Centres (NDCS and NUCOHS) offer subsidised dental care; more complex or specialist periodontal treatment is accessed via referral from a polyclinic or CHAS clinic to qualify for subsidised rates.
Always confirm current fees and your eligibility directly with the clinic, as charges vary.
