No pain does not mean nothing is wrong. Gum disease is usually painless, and people routinely carry an active gum infection for five to ten years — losing bone the whole time — without ever knowing it is there. The early signs exist, but they are small, intermittent, and easy to explain away: a little blood when flossing, a taste that comes and goes, gums that look slightly darker or puffier than they used to. This is the single most useful thing a dental practice can tell people.
If you have noticed any of this and dismissed it, having it measured properly is straightforward.

Why doesn't early gum disease hurt?
Pain is generally a response to acute damage — a nerve exposed, pressure building, tissue torn. Periodontal disease is none of those things. It is a slow, chronic inflammatory process in which the body's response to bacteria under the gum gradually breaks down the ligament and bone holding the tooth in.
That process has no acute event to signal. It runs quietly, in millimetres, over years. By the time a tooth becomes loose or an abscess forms, a great deal of the supporting bone is already gone, and bone that has been lost does not grow back.
This is why the disease is so often described as silent, and why it is usually found at a check-up rather than reported by the patient.
What are the signs people dismiss?
Blood when you floss, but not when you brush
The most common one, and the most commonly explained away as flossing too hard. Healthy gum does not bleed when floss passes through it. Blood on the floss is the body signalling inflammation in a spot the brush never reaches.
People often respond by flossing that area less, which removes the sign without removing the cause. There is more on this in what bleeding gums actually mean.
A taste or smell that keeps coming back
Not constant bad breath — an intermittent metallic or stale taste, often noticed in the morning or after a long gap between meals, that clears after brushing and returns a day later.
It is usually the by-products of bacteria living in a deep pocket, and it tends to be blamed on diet, dehydration or a dry mouth from sleeping.
Gums that look slightly darker or puffier
Healthy gum is firm, pale pink and scalloped tightly around each tooth, with a knife-edge margin. Inflamed gum is redder or darker, slightly rounded rather than sharp at the margin, and looks a little swollen between the teeth.
Because the change happens over years, there is no before-and-after moment to notice. Most people are comparing today's gums to yesterday's, not to the ones they had at twenty-five.
A tooth that feels a fraction different
Not loose, and not sore. Just slightly different when you bite — a fraction higher, or a fraction more mobile, or a sense that the bite has changed on one side.
This is the sign that is most often noticed and least often reported, because it is hard to describe and sounds trivial. It is worth mentioning.
Food starting to catch where it never used to
When bone is lost between two teeth, the gum triangle that used to fill that space recedes, and a gap opens. Food packs in. People buy toothpicks and adapt.
A new food trap between teeth that have not been filled or treated recently is one of the more reliable indications that something structural has changed underneath.
One tooth looking longer than its neighbours
Recession is often localised rather than general, so it shows first as a single tooth that looks a bit long, or a bit more yellow near the gum where root surface is exposed. See receding gums — causes and treatments.
Any of these ringing a bell? Bringing it up costs nothing and settles the question either way.

How is early gum disease actually detected?
Periodontal probing
A fine calibrated probe is walked around each tooth to measure the depth of the space between gum and tooth. Healthy readings are shallow. Deeper readings, and whether the site bleeds when probed, are what distinguish gingivitis from periodontitis and stable sites from active ones.
This measurement is the only way to find pockets. They cannot be seen, and they do not announce themselves.
A full periodontal chart
Where the screening reading suggests it, a full chart records six measurements per tooth, plus recession, mobility and bleeding points. It produces a baseline that can be compared at every future visit, which is what turns a snapshot into a trend.
At Berala Dental a periodontal chart is included where the clinician judges one is needed. It is valued at $150, and it forms part of the fee rather than an addition to it.
X-rays for bone level
Bitewing and periapical X-rays show the height of the bone between the teeth. Bone loss on an X-ray is unambiguous and is often the finding that reframes what someone thought was a minor issue.
Why catching it early changes the outcome so much
Gingivitis — inflammation confined to the gum, with no bone loss — is fully reversible. Treated properly, the tissue returns to health and nothing has been permanently lost. That stage is covered in gingivitis: the stage where gum disease is still fully reversible.
Once bone is lost, the goal changes from reversal to stabilisation. Treatment can stop the disease progressing and can be very effective at doing so, but the bone that has gone is gone.
The costs follow the same pattern. A check-up, X-rays and clean at Berala Dental is $250, including any additional X-rays, fluoride, and a periodontal chart where one is judged necessary. The initial phase of periodontal treatment, once disease is established, is $1,600, with three-monthly maintenance at $400 thereafter. Both figures assume no health-fund contribution; a fund may cover part of it, and a written quote is provided before treatment.
Who is at higher risk?
- Smokers and vapers. Smoking suppresses bleeding, so it removes the most visible warning sign while making the disease worse.
- People with diabetes, particularly where blood glucose is not well controlled. The relationship runs in both directions.
- Anyone with a family history of gum disease or early tooth loss.
- People under sustained stress, or taking medications that reduce saliva flow.
- Pregnant women, whose gums become far more reactive to plaque regardless of how well they clean.
Quick answers
Can you have gum disease with no symptoms at all?
Yes, and it is common. Periodontal disease is usually painless and can progress for years with nothing more than occasional bleeding. It is one of the main reasons routine examinations include periodontal measurement rather than relying on what the patient reports.
Is bleeding when flossing normal?
No. Healthy gum does not bleed when floss passes through it. Bleeding usually means inflammation at that site. If it persists beyond a week or two of consistent, gentle flossing, it should be assessed rather than ignored.
Do I need a specialist to have this checked?
Generally not. Dentists and oral health therapists are trained to diagnose and treat most cases of periodontal disease. Berala Dental is a general dental practice with no periodontist on site, and refers where a case genuinely warrants specialist care. This is covered in do you need a periodontist?
How often should gums be measured?
A periodontal screening reading is taken at routine examinations. Where disease has been diagnosed and treated, a full chart is repeated at the three-month review and periodically after that, so progress is measured rather than assumed.
Having it measured
The point of all of this is not alarm — it is that a measurement takes a few minutes and replaces guesswork with a number. General information on gum disease is published by healthdirect.
Berala Dental has looked after Berala families since 2002, and asking about a small thing early is always welcome.
