How to keep your gums healthy: a guide to gum care

When people think about oral health they think about teeth — clean, white, no cavities. But the gums hold the teeth in, and gum disease is the leading cause of adult tooth loss. It develops silently, and it is almost entirely preventable. This is a practical guide.

What healthy gums look like

Firm, pale pink (darker in people with darker skin), sitting snugly around each tooth, and they do not bleed when you brush or floss.

Signs of trouble: red or puffy gums, bleeding on brushing, tenderness, persistent bad breath, gums pulling away from the teeth so they look longer, or a change in how your teeth meet. Bleeding is the one people dismiss, and it is usually the earliest warning you get.

A one-minute self-check

Good light, a mirror, once a month:

Colour — even, firm pink, or patches of red along the gum edge?
Shape — does the gum come to a neat point between each pair of teeth, or is it rolled and puffy?
Bleeding — run floss between a few teeth. Any blood?
Level — are any teeth looking longer than they did, or is a root surface showing?
The inside of the lower front teeth, where tartar builds fastest — rough, or smooth?
Anything that hurts, catches, or has changed since last month

You are not diagnosing. You are noticing something worth mentioning.

Why it matters

Gum disease starts as gingivitis — inflammation of the gum, fully reversible with good cleaning. Left alone it can progress to periodontitis, where the bone holding the teeth is destroyed. That bone does not grow back. Gum disease is also associated with diabetes, heart disease and other conditions; the associations are real, though causation is not established for most, and the diabetes link is the best supported.

The daily routine

Brush twice a day with fluoride toothpaste, using a soft brush angled at about 45 degrees into the gumline. Gentle circles, not scrubbing — hard brushing causes recession without preventing disease. Two minutes. Spit, do not rinse.

Clean between your teeth every day. This is the single most important thing for your gums, because gum disease starts in the spaces a toothbrush cannot reach. Floss, or interdental brushes for gaps that will take them. If your gums bleed when you start, keep going gently; it usually settles within two weeks as the inflammation resolves.

Brush your tongue — it carries much of the bacteria behind bad breath.

Mouthwash is optional. It does not replace cleaning between the teeth. If you use one, do it at a different time from brushing so it does not rinse away the toothpaste fluoride.

If you wear braces, a denture, a bridge or an implant, ask us how to adapt the routine — each needs something slightly different.

Doing the between-teeth step properly

Since this is the step that matters most for gums, it is worth getting right rather than just getting done.

Floss suits tight contacts. Curve it into a C-shape against the side of one tooth, slide gently just under the gum, sweep up, then repeat against the neighbouring tooth. Snapping it straight down is what makes people sore, and soreness is why most people give up.

Interdental brushes are more effective wherever a gap will take one, and considerably easier to use well. Ask us to size them — too small does nothing, too large is uncomfortable and can damage the tissue.

Water flossers help around bridges, implants and braces, and where dexterity is limited. They complement physical cleaning rather than replacing it.

Once a day, done thoroughly, beats three rushed attempts. Most people find bedtime works best, because what you leave overnight has eight undisturbed hours.

A two-week test worth doing

If your gums bleed, this costs nothing and tells you which problem you have.

Brush twice daily for two full minutes and clean between every tooth every day for fourteen days without missing one. Then floss and watch.

Bleeding stopped — it was gingivitis, and you have just reversed it. Keep going.

Bleeding unchanged, or worse in specific spots — there is calculus below the gumline that no brush can reach. Book.

Expect bleeding to increase slightly for the first few days as inflamed tissue is disturbed. That is normal and not a reason to stop.

What actually helps, ranked

If you are going to change one thing, change the one at the top.

Priority	What	Why it ranks here
1	Clean between the teeth, daily	Gum disease starts where the brush cannot reach
2	Stop smoking	The largest modifiable risk factor, by some margin
3	Brush the gumline gently, twice daily	The junction is where inflammation begins
4	Keep your recall interval	Calculus cannot be removed at home at any effort
5	Control diabetes, if relevant	The relationship runs both ways
6	Reduce snacking frequency	Less plaque acid, less inflammation
7	Tongue cleaning	Breath, mostly
8	Mouthwash	Optional. Never a substitute for 1

Notice that no product appears in the top four. Gum health is almost entirely about disruption and frequency, not about what you buy.

Products, briefly

Toothpaste "for gums" — usually stannous fluoride, which has reasonable evidence for reducing gingivitis. A sensible everyday choice; not a treatment for periodontitis
Chlorhexidine mouthwash — genuinely effective short-term, usually after surgery or for acute inflammation. Stains teeth brown with prolonged use. Use only for the period prescribed
Salt water — soothing after treatment or with an ulcer. Removes no plaque
Alcohol-free rinses — more comfortable, particularly with a dry mouth
Hydrogen peroxide rinses and "gum gels" bought online — generally unnecessary, sometimes irritating
Interdental brushes — the one purchase that reliably changes outcomes

Not everything wrong with a gum is gum disease

Worth knowing, because the treatment differs entirely.

What you notice	Often is	What to do
One swollen, painful spot on the gum	An abscess, from the tooth or the gum	Same-day appointment
A pimple on the gum that comes and goes	A sinus draining infection from a dead nerve	Book. It will not resolve alone
A painful crater-like ulcer	An aphthous ulcer (canker sore)	Usually heals in 7–10 days
Sore, swollen gum behind the last molar	Pericoronitis around a wisdom tooth	Rinse, and book
Gum overgrowing the teeth	Sometimes a medication effect	Tell us and your prescriber
A burn or white patch after treatment	Chemical irritation	Usually settles; get it checked
Generalised soreness with fever, unwell	Can be a viral infection	See a GP or us promptly
Any ulcer, lump, or red or white patch lasting over two weeks	Needs examining	Book. Do not wait

That last row is the important one on this page. Most such things are harmless. Two weeks is the threshold at which it stops being a watch-and-wait.

Gum recession

Different from gum disease, though they can occur together. Recession is the gum moving down the tooth, exposing root surface.

Causes: brushing too hard with a firm brush, gum disease, grinding, thin gum tissue (largely inherited), orthodontic movement, and a lip or tongue piercing rubbing on one spot.

Consequences: sensitivity, root surfaces that decay faster than enamel, and appearance.

What helps: a soft brush and light pressure, a sensitivity toothpaste used as your everyday paste, treating any grinding, and monitoring so we know whether it is stable or progressing. Photographs and measurements are how that question gets answered.

Lost gum does not grow back. Grafting, by a periodontist, is the only way to cover exposed root, and it is not needed in most cases. See gum recession.

Professional care

Plaque you miss hardens into calculus, which no toothbrush removes. A professional clean takes it off, above and below the gumline, and the examination measures the gum pockets around each tooth so changes are tracked rather than guessed at.

Six months is the usual interval; it is a default, not a rule. If you have had gum disease, expect three- or four-monthly maintenance, sometimes indefinitely, because periodontitis is controlled rather than cured.

The numbers called out during charting

Those numbers are the depth in millimetres of the crevice between gum and tooth, measured at six points around each tooth.

1–3mm, no bleeding — healthy
1–3mm with bleeding — gingivitis: reversible, no bone lost
4–5mm — a pocket deeper than a toothbrush reaches
6mm and above — established periodontitis

Ask to be told yours. Recorded, they let the next visit answer the only question that matters: better, the same, or worse.

Diet and habits

Sugar frequency matters more than quantity — keep sweet things to mealtimes and drink water in between. Crunchy vegetables and firm fruit stimulate saliva, which helps clear acid. A varied diet with enough vitamin C supports gum tissue.

Smoking is the single biggest modifiable risk factor for gum disease, and it hides the warning signs by reducing bleeding. Stopping is the best thing you can do for your gums.

Manage diabetes if you have it; the two conditions feed each other.

Vaping is not a neutral alternative. The evidence is still developing, but it is associated with dry mouth and gum irritation, and it is not something we would describe as gum-safe.

Gums through life

Teenagers — hormonal changes make gums respond more strongly to the same plaque, and braces make cleaning harder at exactly the wrong moment.

Pregnancy — pregnancy gingivitis is common, usually settles after the birth, and responds well to a clean. Dental care during pregnancy is safe. See dental health during pregnancy.

Menopause — some people notice drier, more tender or burning gums. Worth raising rather than enduring.

Older adults — medication-related dry mouth, recession exposing roots, and dexterity all change what works. Adaptations exist for all three.

Anyone on immunosuppressants or having cancer treatment — tell us before treatment starts where you can. There is a great deal that can be done in advance.

Things that change the picture

Some circumstances raise gum risk regardless of how well you clean, and are worth telling us about:

Pregnancy, which exaggerates the gum response to the same plaque
Medications causing dry mouth — several hundred common ones do
Medications causing gum overgrowth, including some anti-epileptics, immunosuppressants and calcium channel blockers
Diabetes, particularly when control is difficult
Family history — susceptibility is partly inherited
Stress, which affects immune response and tends to disrupt the routine
A lip or tongue piercing rubbing on the gum

Around implants, bridges and dentures

The gum around dental work needs more attention, not less.

Implants have no periodontal ligament, and gum disease around one — peri-implantitis — can progress faster once established. Clean around the neck of every implant daily and keep the recall interval you are given.

Bridges need a floss threader or superfloss to reach under the false tooth. Nothing else gets there, and that space is where problems start.

Partial dentures put load on the teeth their clasps sit on. Clean the plate separately, and clean those teeth with particular care.

When to book

Bleeding that does not settle within two weeks of proper cleaning, persistent bad breath, soreness, gums receding, or a loose tooth. Early treatment is simple and usually a clean plus home-care changes. Late treatment is deep cleaning, maintenance for life, and sometimes referral to a periodontist.

We are a general dental practice and hold no specialist registration; surgical gum treatment is referred to a registered periodontist.

Questions we are asked

My gums bleed — should I stop flossing that spot? No, that is backwards. The bleeding is inflammation from plaque left there, and avoiding it makes it worse.

Is bleeding just from brushing too hard? Usually not. Over-brushing more typically causes recession and notching than bleeding.

Can I fix gum disease with mouthwash? No. It can reduce inflammation short-term but removes neither plaque nor calculus.

If I have no pain, can my gums still be in trouble? Yes — that is the characteristic feature. Periodontitis is largely painless until it is advanced.

Do receded gums grow back? No. Stopping progression is the realistic goal; grafting by a periodontist is the only way to cover lost root surface. See gum recession.

Are bleeding gums a vitamin deficiency? Very occasionally — severe vitamin C deficiency does cause bleeding gums, and it is rare in Australia. In almost every case the cause is plaque.

Is gum disease hereditary? Susceptibility is partly inherited. The plaque is not. Two people with the same routine can have genuinely different outcomes, which is unfair and worth knowing.

Can I brush a sore gum? Yes, gently. Leaving it alone is what keeps it sore.

What is the single most effective thing for gum health?

Cleaning between the teeth every day — floss, interdental brushes or a water flosser. Gum disease starts in the spaces a toothbrush cannot reach, so brushing alone leaves the very surfaces where the problem begins. If you do one new thing, make it this.

How should I brush for healthy gums?

Twice a day with fluoride toothpaste and a soft, small-headed brush, angling the bristles into the join between tooth and gum and using small gentle circles — that junction is the part that matters and the part most often skipped. Spit, do not rinse. Hard scrubbing with a firm brush causes recession and worn notches at the gum line, both permanent, so ease off if your brush splays within weeks.

What do healthy gums look like?

Firm, sitting snugly against the teeth, not bleeding when brushed or flossed, not swollen or tender. Colour varies between people — natural brown or dark pigmentation is normal, particularly in people with darker skin, and is not a sign of disease. Firmness and absence of bleeding matter more than shade.

What are the warning signs?

Bleeding when brushing or flossing, redness or puffiness at the gum margin, tenderness, persistent bad breath, gums pulling away so teeth look longer, sensitivity on exposed roots, and later teeth that loosen, drift or change how they meet. Gum disease is usually painless, which is precisely why it progresses unnoticed.

Bleeding started when I began flossing — should I stop?

No — keep going. Gums that are already inflamed bleed when first disturbed, and that settles within one to two weeks as the inflammation resolves. Stopping lets the plaque build straight back up. Be gentle, curve the floss around each tooth rather than snapping it down, and if bleeding persists beyond a couple of weeks, have it assessed.

What else affects gum health?

Smoking most of all — and it also suppresses bleeding, masking the warning sign. Poorly controlled diabetes works in both directions with gum disease. Stress, medications that dry the mouth or cause gum overgrowth, pregnancy and hormonal changes, and crowded teeth or overhanging fillings that trap plaque all play a part. A diet high in sugar feeds the plaque.

Does mouthwash help?

It is an optional extra, not a substitute for cleaning between the teeth. An antibacterial rinse can help in the short term where one has been recommended for you, but strong alcohol-based rinses dry the mouth and daily long-term use of chlorhexidine stains the teeth. Nothing in a bottle removes plaque that is physically stuck to a tooth surface.

When should I see someone?

If your gums bleed regularly, if they are receding, if there is persistent bad breath, or if anything feels loose — rather than waiting for the next routine visit. Proper assessment means measuring the pockets around every tooth and taking X-rays.
