It is morning.
You brush. You spit. And in the sink you see pink. Not much. Maybe you ignore it. You have three minutes before the train. But the next morning it is there again. And the morning after that too.
Maybe you recognize the quiet thought that follows:
"I take good care of my teeth. I brush twice a day. I try to floss, sometimes. Still, it bleeds regularly. My friends never have this. Could it be that I am just... sensitive?"
That is a question I hear in practice every day. And the short answer is: no.
You are not 'sensitive.' Your gums are inflamed.
Bleeding gums are not a personality trait. They are not a brushing mistake either. They are inflammation. And your gums are telling you something your toothbrush simply cannot solve.
What doctors call "gum inflammation" does not happen on top of your tooth. It happens underneath it. Under the edge of your gum sits a thin layer of bacteria, a biofilm, that settles there and no longer disappears with brushing alone. No toothbrush reaches under that edge. No mouthwash rinses it away. The biofilm remains. Your gums respond by becoming inflamed. And inflamed gums bleed.
That is it. Not complicated. But uncomfortable to hear. Because the advice you have probably received for years, "brush better, floss more," does not attack the problem at its root.
"Brushing better" does not work
You have probably already been to your dentist with this complaint. You were told what everyone is told: floss more, brush better, maybe get a new toothbrush. Add a mouthwash. And you tried.
This is what I hear in the chair:
- "I try to floss. I keep it up for two days, then I forget again."
- "Toothpicks feel absolutely awful in my mouth."
- "I used Parodontax. And Sensodyne. And Listerine. It still bleeds."
Honestly: for someone with already inflamed gums, flossing really hurts. It bleeds, sensitive spots become even more irritated, and it seems to make the problem worse. Of course you stop after a few days.
And you are not the only one. I see this pattern in everyone. Research shows that most people who start flossing stop again within one to two weeks: not one in ten, but the overwhelming majority. It is a habit that does not fit how we live. And even if you do keep it up: no matter how well you floss, you still do not reach the biofilm below the gumline. That is where the problem is. No tool you currently put in your mouth, whether floss, interdental brushes or toothpicks, gets there.
So brushing better does not help. Not because you are doing something wrong, but because your mouth is built in a way that your toothbrush cannot reach there.
"But my friends never have this"
This may be the quiet thought that hurts the most.
You do everything asked of you. Brush twice a day, use a 180€ sonic toothbrush, go for check-ups every six months. Your friend, who never flosses, drinks coffee like water and has not been to the dentist in years, has perfect teeth. You do not.
Honestly: this is not a punishment for being careless.
Gum inflammation arises from a combination of bacterial growth, genetic sensitivity, hormonal changes (pregnancy is a known trigger) and stress. Two people with exactly the same brushing routine can have completely different gum responses. You are not doing anything wrong. You simply have a mouth that reacts to this biofilm. Your friend's mouth happens not to.
In other words: guilt plays no role here. What you have is a chronic infection. And a chronic infection needs a different kind of help than a toothbrush can offer.
But before we talk about that help, one important reality: this inflammation does not go away on its own. And where it leads in the long run if you do nothing is surprisingly well documented in the Netherlands. By the KNMT, our dental federation.
What 'doing nothing' actually means
There is a word dentists do not like to use before they are sure: periodontitis. Or, in everyday language: chronic gum inflammation that has spread into the jawbone.
Periodontitis is the most common cause of tooth loss among adults in the Netherlands. And it is unexpectedly silent. It often does not hurt. It gives hardly any symptoms for years. Only at an advanced stage do real complaints appear: a tooth that shifts, exposed roots, a molar that suddenly starts to feel loose. By then, the jawbone has already broken down significantly, often to the point where teeth visibly move.
In other words: you only feel it when it is already late.
The bleeding you see in the sink now? That is one of the few early signals you can observe. Your gums are telling you something before the damage becomes irreversible.
Max: the KNMT's own patient profile
The KNMT, the Dutch dental federation, publishes an example patient on allesoverhetgebit.nl to explain to people how periodontitis unfolds in practice. His name is Max. This is literally what it says:
"Max has had swollen and bleeding gums for years. The dentist has said several times that it is important to do something about it. But he kept putting it off. Unfortunately, the gum inflammation has now spread to the jawbone."
"Costs this year: 3,461.97€."
"He knows it is five to midnight and that there is a chance he will lose all his teeth and molars."
— KNMT / allesoverhetgebit.nl
Read that again.
Max started with the same complaint. Swollen, bleeding gums. The dentist had told him. But something kept getting in the way.
And Max does not exist for marketing: he is the official example the dental federation itself uses to explain to patients why you cannot leave this complaint for years.
"On Friday I get to donate several molars to the oral surgeon, after years of successfully denying and avoiding it."
— anonymous, r/thenetherlands
Someone wrote that a few months ago on a Dutch forum. The same story as Max, but in the first person. Years of denial. Then an appointment with the oral surgeon.
Have you ever wondered why older people often no longer have a full set of teeth? For the vast majority, it started like this: bleeding gums that grew into bone loss and periodontitis that, at that point, was no longer reversible.
What it costs, and what basic insurance does not cover
Dental care for adults has for years been almost entirely outside basic health insurance. Supplementary dental insurance usually reimburses between 250€ and 1,500€ per year. In practice, that buys you at most one treatment pathway. The rest you pay yourself.
The numbers (Independer.nl, 2026 + KNMT fees):
- Gum treatment, first phase: 400€ to 1,500€
- Full periodontology pathway (four sessions, often under anesthesia): about 1,600€
- Implant, if a tooth eventually cannot be saved: about 2,100€ per element
- Max in his most expensive year: 3,461.97€
Maximum reimbursed by your supplementary insurance? Often around 500€ to 1,000€. Sometimes less.
And this is the part nobody likes saying out loud
Early gum inflammation, with bleeding and sensitivity but without jawbone loss, is reversible. With the right care it disappears and your gums recover. Once the inflammation has reached the jawbone and bone has broken down, the story changes: from that point, progression can still be stopped, but lost jawbone cannot be rebuilt.
No brushing routine brings that bone back, however strict. Another toothpaste does not either. Antibiotics only attack the bacteria. They cannot rebuild bone that is already gone.
"Unfortunately, the lost supporting tissue recovers little or not at all."
— Mondzorg Minke
That is exactly why early action makes the difference. The period in which everything can still fully reverse does not stay open forever.
So what do you do in that period? Between "it sometimes bleeds" and "I have to donate molars to the oral surgeon"?
Not brush harder. Not finally learn to floss. Something else.
What 200 patients did at home, and what made the difference
Lumoral is not in the same category as your toothpaste or mouthwash. It is a medical device, Finnish, CE-marked Class IIa, developed by dental researchers in Helsinki, that combines a light-activated rinse with dual-light therapy. Periodontologists have used that same principle, photodynamic therapy, in the treatment room for longer. The difference: Lumoral is made for home use.
How it works: three steps
You rinse your mouth with the Lumorinse rinse. It contains a light-sensitive molecule that attaches to bacteria in your mouth, especially the biofilm below your gumline.
You click the mouthpiece into your mouth. It emits combined blue light (405 nm) and red light (810 nm) for ten minutes.
The light activates the molecule. The activated molecule reacts with the bacteria in the biofilm: where your toothbrush cannot reach and where no floss, mouthwash or toothpaste has been able to make the difference.
Ten minutes. On the couch, while you watch an episode. That is it.
The HOPE-CP study: n=200
Lumoral was tested in HOPE-CP, the largest European study on periodontitis care to date.
200 patients with stage I to III periodontitis. Randomly divided into two groups. One half received standard care: professional cleaning, a new sonic toothbrush, instructions. The other half received the same standard care plus daily Lumoral at home.
After six months:
- Twice as many patients in the Lumoral group reached clinically healthy gums (BOP below 10% — the European definition of healthy gums): 51% versus 23% in the standard care group.
- One and a half times as many patients achieved good plaque control (plaque index below 10%): 63% versus 38%.
- Adherence remained high: 85% of Lumoral users were still using it daily after six months. Not like flossing, then.
The results were published in January 2026 in the Journal of Periodontology, the peer-reviewed journal of the American Academy of Periodontology. Fully readable (DOI: 10.1002/jper.70082).
Frequently asked questions
How three Dutch people experienced it
"I have not flossed my whole life. Really. My dentist said it every six months, and every time I thought: yes, yes. Then I was told my gums were bleeding during a professional cleaning, not just in the sink in the morning. A friend tipped me off about Lumoral. I had no idea whether I believed in it. After six weeks: no more pink in the sink. My hygienist asked whether I had changed something."
— Lotte, 42, Utrecht
"Honestly, I was not positive about this. It costs 249€ and I had used Parodontax for years, which worked fine, I thought. But it still bled. A few weeks of Lumoral and I have to admit it: the difference is clear. I still use it, and at first I thought I would leave it after a month."
— Pieter, 51, Amsterdam
"During my pregnancy my gums started bleeding. My hygienist said it would get better on its own after giving birth. It did not. I wanted something I could do at home, without antibiotics. Lumoral fits into my morning routine. I switch it on while I drink my coffee. The bleeding was gone after six weeks."
— Sara, 36, Rotterdam
What it costs
Lumoral costs 249€. One time. You pay for the device once and that is it — no subscription you get stuck in.
The list from the previous section again, now with this price included:
- 249€ — Lumoral, one time (10 min/day at home)
- 400€ to 1,500€ — first gum treatment
- 1,600€ — full periodontology pathway
- 2,100€ — implant per element
- 3,461.97€ — Max in his most expensive year (KNMT)
Lumoral is the smallest cost in this whole list. And the only one you use before the damage instead of after.
30 days to experience it
Does it not work for you? Then return it within 30 days. You get your money back, minus return shipping costs. No survey afterwards.
For anyone hesitating: I ask people to try it consistently for six weeks before judging. In almost all cases, they already see a difference in the sink during those six weeks. And if that difference is not there for you: fine, you simply get your money back.
Finally
There is no technique to learn. It does not hurt. The discipline it asks for is the discipline of one episode on the couch. For something your toothbrush, your floss, your mouthwash and even your six-month check-up cannot solve.
My only addition as a hygienist: keep going to your dentist and dental hygienist. Lumoral replaces neither. It is what you can do yourself in the months between visits. For the first time, with something that reaches below the gumline, where your toothbrush cannot.
If the pink in the sink is telling you something, listen now.
