Gingivitis vs Periodontitis: What's the Difference?

What Is Gingivitis?

Gingivitis is inflammation of the gum tissue only. Plaque accumulating along the gumline irritates the gums, and they respond the way any inflamed tissue does — by becoming red, swollen and quick to bleed. Crucially, at this stage the infection has not touched the structures that actually hold your teeth in place: the periodontal ligament and the jawbone beneath.

The classic signs of gingivitis are:

• Red or puffy gums — healthy gums are pale pink and firm; inflamed gums look darker, rounded and slightly swollen
• Bleeding when brushing or flossing — the most common and most ignored sign
• Bad breath — from the bacteria collecting along the gumline

Notably, gingivitis is usually painless — which is exactly why so many people live with it for years without realising anything is wrong.

What Is Periodontitis?

Periodontitis is what gingivitis can become when the inflammation is left to smoulder. The gum begins to detach from the tooth, creating pockets — small gaps between tooth and gum where plaque and tartar collect beyond the reach of any toothbrush. Inside these pockets, the infection works its way down the root, and the body's own inflammatory response starts to break down the periodontal ligament and the jawbone that anchors the tooth.

That bone loss is the defining feature of periodontitis — and it is permanent. Treatment can stop the disease from taking more bone, but it cannot regrow what has already gone. Signs that gum disease has reached this stage include:

The word to hold onto is manageable. Periodontitis cannot be reversed, but with proper treatment and maintenance it can be stopped and kept stable for decades — most patients who commit to care keep their natural teeth.

How Gingivitis Becomes Periodontitis — and How Fast

The path from one stage to the other is gradual. Plaque left on the teeth begins to harden into tartar (calculus) within days, and tartar cannot be brushed away — it has to be professionally removed. As tartar accumulates at and below the gumline, it gives bacteria a permanent, rough foothold, and the inflammation slowly deepens from the gum into the supporting structures.

How fast this happens varies widely from person to person. In some people, gingivitis simmers for years without ever crossing into periodontitis; in others — particularly smokers and people with diabetes — the transition can happen within months. There is no reliable way to predict which camp you fall into, which is why treating gingivitis early is always the safer path.

How Each Stage Is Treated

Treating gingivitis: a clean and a fresh start

Gingivitis treatment is refreshingly simple. A professional clean removes the plaque and tartar driving the inflammation, and daily brushing and flossing keep it from returning. At Vera Dental, scaling and polishing starts from $99, and CHAS Blue and Orange card holders enjoy subsidies on the fee. Expect your gums to bleed a little less each day after the clean — most patients see them return to healthy pink within a fortnight.

Treating periodontitis: deeper cleaning and ongoing care

Because the infection sits in pockets below the gumline, periodontitis needs a deeper clean — root debridement — where the root surfaces are carefully cleaned under local anaesthetic, usually over more than one visit. After that, the disease is kept stable with maintenance cleans every three to four months, closer monitoring of pocket depths, and diligent home care.

The right treatment plan starts with an accurate diagnosis. At a $40–$50 consultation, your dentist measures the pockets around each tooth, checks bone levels on an X-ray, and tells you exactly which stage your gums are at and what care they need. You can contact our Tanjong Pagar clinic to arrange a gum assessment — we are a 3-minute walk from Tanjong Pagar MRT.

Why Untreated Periodontitis Leads to Tooth Loss

A tooth is only as secure as the bone around it. As periodontitis dissolves that bone, even a completely healthy, cavity-free tooth gradually loses its anchorage — it loosens, drifts, and eventually cannot be saved. This is why gum disease, not decay, is one of the leading causes of tooth loss in adults, and why a disease that starts as a little bleeding during brushing deserves to be taken seriously.

If periodontitis has already claimed a tooth, it can be replaced — dental implants in Singapore restore both the tooth and the chewing function it provided. But two things are worth knowing. First, keeping your own teeth is always preferable to replacing them, and gum treatment is far simpler and more affordable than any replacement. Second, gum health must be stable before implant treatment can begin — an implant placed into gums with active disease is vulnerable to the same infection that damaged the natural tooth.

A Quick Gum Self-Check

In front of a mirror, take thirty seconds to look for these signs:

• Do your gums bleed when you brush or floss — even a little pink in the sink?
• Are the gums along any teeth red or puffy rather than pale pink and firm?
• Do any teeth look longer than they used to, or is any root surface showing?
• Have gaps appeared between teeth, or does any tooth feel slightly mobile?
• Does bad breath return soon after brushing?

The first two signs suggest gingivitis; the last three point towards periodontitis. Either way, if you ticked any box, a gum assessment is worthwhile — and if bleeding is your main concern, our guide to stopping bleeding gums covers what you can do at home in the meantime.

Preventing Gum Disease Altogether

Prevention is beautifully unglamorous: brush twice a day with the bristles angled into the gumline, clean between your teeth daily with floss or interdental brushes, and have a scaling and polishing every six months so tartar never gets the chance to establish itself. If you smoke, quitting is the single most powerful thing you can do for your gums; if you have diabetes, keeping it well controlled protects your gums as much as the rest of your body.
