You brush your teeth, you spit, and there is pink in the sink. Like yesterday. Like last week. You have probably told yourself it is the brush, or that you press too hard.
It isn't.
Healthy gums do not bleed. Not under a brush, not under floss, not in the apple you bite into. Bleeding is not a minor hygiene detail — it is a signal of inflammation, and it is the first step on a staircase you really do not want to walk down.
The sign you must never wave away
Blood when you brush means one thing: the gum is inflamed. In the overwhelming majority of cases the cause is dental plaque, the invisible bacterial film that rebuilds itself within hours and, left in place, hardens into tartar. And tartar no longer comes off with a brush.
The other signals, usually creeping in slowly:
- red, swollen, shiny gums — healthy gum is pale pink and firm;
- persistent bad breath that resists mouthwash and returns during the day;
- teeth that seem to be "getting longer": the tooth is not growing, the gum is retreating and exposing the root;
- new sensitivity to cold, to sugar, to air;
- and, later, teeth that move, drift apart, or open up gaps that were never there before.
That last sign is the latest to appear — and the most serious. A loose tooth in an adult is never trivial.
Gingivitis: still completely reversible
Gingivitis is inflammation limited to the gum. It bleeds, it swells, it is tender. But the bone that holds the tooth in the jaw is still intact.
And here is the good news, the one that should make you pick up the phone: at this stage, everything is reversible. A professional cleaning that removes plaque and tartar, a brushing technique put back on track, daily cleaning between the teeth — and within two to three weeks the gum turns pink and firm again and stops bleeding. No lasting damage. No permanent loss.
That is precisely why waiting is expensive. Gingivitis is the only stage where you can turn back.
Periodontitis: what is lost does not come back
If the inflammation persists, it eventually travels down. It detaches the gum from the tooth, hollows out what dentists call a periodontal pocket, and attacks the bone and the fibres that anchor the root. At that point it is no longer gingivitis but periodontitis — and the difference is fundamental.
Let us be completely straight with you, because everything else follows from this:
Bone destroyed by periodontitis does not grow back. The disease can be stopped. The pockets can be cleaned out, the inflammation resolved, further loss prevented, and the teeth kept in place for many years. But the periodontal support that is gone is not "repaired". A practitioner who promises to give you all of it back is not telling you the truth.
In carefully selected situations, regenerative surgical techniques do exist, and a dentist can discuss them with you if your case is suitable. They do not apply to everyone and they do not hand you a brand-new foundation. The realistic goal of periodontal treatment is stabilisation — and that is a great deal, because untreated periodontitis eventually costs you teeth.
The trouble is that it advances in silence. It is rarely painful. You can lose bone support for years with no other sign than a little blood when you brush and breath you would rather not mention.
Blood in the sink for weeks, gums that swell, a tooth that feels slightly loose? Don't wait for the next stage. Find a dentist near you on OlamKal and book in a few clicks — a gum assessment takes one appointment.
What the dentist actually does
You will not be judged on your brushing. You will be examined. Here is what to expect.
Periodontal probing. With a very fine graduated probe, the dentist goes around every tooth and measures the depth of the space between gum and root. It is painless or nearly so, a little uncomfortable where things bleed. Recorded tooth by tooth, these measurements are the real photograph of your gums: they show whether there are pockets, where, and how deep.
X-rays. They reveal the level of the bone around the roots — something no visual examination can show. This is what tells you whether you are dealing with gingivitis or whether the bone has already started to go.
Scaling. Tartar and plaque above the gum line are removed, with ultrasonic instruments and by hand. In gingivitis, this is very often enough.
Root planing (subgingival debridement). When pockets are present, the surfaces below the gum, along the roots, have to be cleaned of the tartar and biofilm a toothbrush will never reach. It is done under local anaesthetic, over one or several sessions depending on how much ground there is to cover. It is the central act of periodontal treatment.
Then follow-up. Your dentist will see you again to check the response: have the pockets closed, has the bleeding stopped? Some areas may need an additional surgical step. And above all, a stabilised periodontitis remains a chronic disease: it requires regular check-ups, for life. That is not a commercial subscription — it is the condition for not sliding backwards.
Gums and general health: what we can say, and what we cannot
You may have read that gums "cause" heart disease or diabetes. Let us stay rigorous.
What is documented is an association between periodontal disease and certain general conditions, first among them diabetes. The two are frequently found together, and people whose diabetes is poorly controlled often have gums in worse shape.
What we cannot claim is a demonstrated cause-and-effect link, in either direction. An association is not causation, and anyone telling you "treat your gums and your diabetes will be cured" is going far beyond what the science supports.
The practical conclusion, though, is simple and solid: if you have diabetes, tell your dentist, and have your gums watched more closely. The same goes if you smoke — tobacco worsens periodontal disease and, by narrowing the blood vessels, it masks the bleeding: your gums can be badly diseased without you seeing a single drop of blood. It is one of the most dangerous traps of this condition. The NHS and the World Health Organization publish clear guidance on oral health.
When it is an emergency
Most gum problems are not a matter of hours. Some are.
Call 101 immediately if you have: swelling of the face or neck that is spreading, difficulty swallowing or breathing, difficulty opening your mouth, or a high fever with a dental abscess. A mouth infection spreading toward the neck is a life-threatening emergency — it does not wait, and it is not treated with a painkiller and a night's sleep.
See your dentist promptly, rather than taking the next free slot in a month, if you have an abscess, throbbing pain, a swollen gum, a persistent bad taste, or a tooth that has become loose.
What you can do tonight
None of this replaces an appointment, but all of it counts:
- brush twice a day, two minutes, with a fluoride toothpaste, working gently right along the gum line — that is where plaque collects;
- clean between your teeth every day (floss or interdental brushes): the brush does not reach the place where gingivitis begins;
- do not stop brushing an area because it bleeds. That is the natural reflex and it is the worst one. An inflamed gum bleeds; cleaning it is what makes it stop;
- if you smoke, know that this is the single most powerful aggravating factor you actually control.
The bottom line
Blood when you brush is a message. Caught at the gingivitis stage, it costs you one cleaning and three weeks of proper brushing — and everything goes back to how it was. Ignored, it becomes a disease that destroys bone nobody can give you back.
The difference between the two, very often, is simply having booked in time.
Gums that bleed, swell, or just don't feel right? Book with a dentist near you on OlamKal: a gum examination, a few X-rays, and you will know exactly where you stand — while it is still reversible.
