3.69 billion people live with a major oral condition, and severe gum disease alone affects 1.1 billion. Yet the figure that should change how you decide is smaller and more specific: a root-canal-treated tooth survives 89% at ten years with a crown and 62% without. What determines the outcome is usually not the procedure you are worried about. Noria Health arranges assessment and treatment with Belgian specialists and coordinates the pathway end to end.
The decisive factor is rarely the one people worry about
Across a US insurance database of 1,462,936 root-canal-treated teeth, survival at eight years is 97%, and 81% at twenty years in a smaller cohort followed 5 to 37 years. Those are good numbers. But they split sharply on one variable that has nothing to do with the canal:
| What is measured | At 5 years | At 10 years |
|---|---|---|
| Survival with a crown | 94% | 89% |
| Survival without a crown | 77% | 62% |
The heaviest single factor, measured at roughly six times over, sits outside the canal. A tooth left without full coverage is lost far faster than one that was properly restored. If you are being quoted for a root canal, the question to ask is what goes on top of it and when — not how many appointments the canal itself will take.
The same pattern appears with implants. Implant survival is 97.2% at five years and 95.2% at ten. The crown mounted on it survives 96.3% and 89.7%. The implant outlives its crown. Anyone quoting you an implant success rate without saying which of the two they are quoting is telling you half the story.
How fast decay actually moves
Caries is treated as an emergency or as nothing at all, and neither is right. The published survival of a surface, by stage:
| Stage of the lesion | How long 75% last before progressing |
|---|---|
| Sound surface | 6.3 years before reaching inner enamel |
| Lesion confined to enamel | 4.8 years before reaching dentine |
| Lesion reaching the enamel-dentine junction | 1.3 years |
There is a threshold, and it is at the enamel-dentine junction. Before it, you have years and monitoring is reasonable. After it, you have months. That is the whole argument for a proper assessment rather than a glance.
And once the pulp is exposed in a deep adult lesion, direct capping or partial pulpotomy achieves only 9% success at five years. The window for conservative treatment closes.
Gum disease, the condition nobody is sent abroad for
Severe periodontitis affects 1.1 billion people, peaks in incidence around age 38, and costs Europe an estimated 156 billion euros a year in lost productivity. It is also the least dramatic thing on this page, which is exactly why it goes untreated.
The evidence on what works is unglamorous and strong. In a reference cohort of 375 patients followed for 30 years with recalls every 3 to 12 months as needed, only 21 teeth in total were lost to periodontitis or progressive caries. Maintenance, not heroics.
One association worth knowing: across 13 studies and 49,262 people, periodontitis risk in people with diabetes is raised by 86%.
Why people cross a border for this
Across the European Union, forgone dental care is almost three times more frequent than forgone medical examination, and cost is the reason given. Dentistry sits outside most public cover, so the barrier is not a waiting list — it is the bill, and the fact that treatment is often quoted piecemeal.
We will not tell you what treatment costs in Belgium, here or anywhere. Publishing medical prices is prohibited by Article 37 of the Belgian Code of Medical Ethics, and a figure quoted before anyone has looked in your mouth is a figure that will change.
What the pathway looks like
- Your records, read first. Radiographs, cone-beam imaging where you have it, and any treatment plan you have already been given, transferred securely and reviewed before anything is booked.
- Assessment with a Belgian specialist, with imaging in the same visit where indicated.
- A written plan, in stages, saying what is urgent, what can wait, and what does not need doing. A plan that treats everything at once is a sales document.
- Treatment and follow-up coordinated, with the report and imaging sent back to your own dentist so that maintenance happens where you live.
On timing: Noria confirms the schedule once your file has been reviewed. The 48-hour consultation and 7-day surgery windows apply to the specialties where a physician is on immediate standby — orthopaedics, ENT, chronic pain and preventive assessment. Dental pathways are scheduled to the specialist’s availability, and we tell you the date rather than a promise.
What Noria Health does not do
- It does not employ dentists or surgeons and does not practise medicine. The treating specialist decides.
- It is not an insurer and does not fund treatment.
- It does not publish medical prices and does not compare the prices of clinics or practitioners — Article 37 of the Belgian Code of Medical Ethics prohibits it.
- It does not publish patient testimonials. Health data is a special category under Article 9 of the GDPR.
Questions patients actually ask
Is it worth crowning a root-treated tooth?
On the published survival data, yes, and it is the single largest factor: 89% survival at ten years with a crown against 62% without. Ask when the crown goes on, not only what the canal costs.
How long do implants last?
The implant itself: 95.2% at ten years. The crown on top: 89.7%. The failure, when it comes, is usually above the bone rather than in it, and that changes what maintenance you should expect to pay for.
Do I have to treat a small cavity immediately?
It depends on the stage. A lesion confined to enamel gives you years; one that has reached the enamel-dentine junction gives you about eighteen months. That distinction is what an assessment is for.
Can I have dental treatment in Belgium if I live abroad?
Yes. Belgian practices treat self-paying international patients, and no prior authorisation is needed when you pay privately.
Who looks after the work afterwards?
Your own dentist. The plan, radiographs and treatment record go back at discharge. Ask about this before you travel, for any provider — it is where cross-border dentistry most often falls down.
