Gum disease usually announces itself long before it costs you a tooth — most often as gums that bleed when you brush, look red or puffy, or have started to pull back from your teeth. Caught early, it's very treatable. Left alone, periodontitis is the leading cause of tooth loss in adults, which is why these warning signs are worth taking seriously.
The reassuring part is that the early stage is fully reversible, and even advanced gum disease can usually be stopped in its tracks. Knowing what to look for, and acting on it early, is what makes the difference.
From gingivitis to periodontitis
Gum disease develops in stages, and the earlier stage is where it's easiest to turn around.
It starts as gingivitis — inflammation of the gums caused by plaque building up along the gumline. The gums become red, puffy and bleed easily, but the bone and fibres holding your teeth are still intact. At this stage the damage is fully reversible with a professional clean and better home care.
If plaque and hardened tartar are left in place, gingivitis can progress to periodontitis. Now the inflammation spreads deeper, the gum begins to separate from the tooth to form pockets, and the bone that anchors the tooth slowly breaks down. This deeper damage can be halted, but the bone already lost doesn't grow back — which is exactly why catching it early matters so much.
Warning signs you shouldn't ignore
Gum disease is often painless until it's advanced, so it pays to watch for the quieter signs. Check yourself against this list:
- Bleeding when you brush or floss — the most common early sign, and not something to accept as normal.
- Red, swollen or tender gums rather than firm and pale pink.
- Gums that are receding, making teeth look longer than they used to.
- Persistent bad breath or a bad taste that doesn't shift.
- Teeth that feel loose, or have started to move or splay apart.
- A change in your bite, or dentures that suddenly fit differently.
One or two of these — especially bleeding — is a reason to book a check-up, not to wait and see.
What raises your risk
Gum disease is driven by plaque, so anyone can develop it — but some things make it more likely and quicker to progress:
- Smoking is one of the strongest risk factors, and it also hides the warning signs by reducing the bleeding that would otherwise flag a problem.
- Diabetes, particularly when blood sugar isn't well controlled, leaves the gums more vulnerable to infection.
- Hormonal changes during pregnancy or menopause can make gums more reactive and prone to inflammation.
- Genetics can leave some people more susceptible even when they look after their teeth well.
- Medications that dry the mouth, and ongoing stress, can also play a part.
None of these means you'll definitely develop gum disease, and none of them removes the value of good daily cleaning. But knowing which apply to you helps us decide how closely to keep an eye on your gums.
Why it matters beyond your mouth
Untreated periodontitis is the single biggest cause of tooth loss in adults — not through decay, but by destroying the foundation that holds teeth in place. That alone is reason enough to act early.
There's also growing interest in how gum health connects to general health. Research has found associations between gum disease and conditions such as heart disease and diabetes — for example, poorly controlled diabetes and gum disease appear to influence one another. It's important to be clear that these are associations, not proof that one directly causes the other. Even so, keeping your gums healthy is a sensible part of looking after your overall wellbeing.
How periodontitis is treated
Treatment aims to clear the infection, stop the bone loss and keep it from coming back. Depending on how far it has progressed, that can involve:
- A thorough scale and clean to remove the plaque and tartar driving the inflammation. Our guide to why regular scaling matters explains this first step.
- Deep cleaning (root planing) to clean below the gumline and smooth the root surfaces so the gum can reattach.
- Ongoing maintenance — more frequent periodontal treatment and reviews to keep the pockets stable, since periodontitis is managed rather than cured.
Most cases are controlled well without surgery when they're caught in time. The key is starting before more bone is lost.
Just as important is what happens at home between visits. Because gum disease is fuelled by the plaque you don't remove, day-to-day brushing and cleaning between the teeth do most of the work of keeping it at bay. We'll show you the technique that suits your mouth, so the results of any treatment actually hold. Treating the gums in the chair and neglecting them at home rarely works for long; the two go together.
