In this guide
Dutch dental care is the one part of the health system that behaves like the country you came from: you pay for it. Adults sit outside the basic package for almost everything, bills arrive per treatment code, and the only cover on offer is bought separately.
Whether it is worth buying is an arithmetic question with three inputs, and the marketing gives you one. Here is how to get the other two.

What turning 18 takes away
Until your eighteenth birthday, Dutch dental cover is close to complete and costs nothing extra: the basic package pays for the annual check-up, tartar removal, fluoride treatment twice a year once adult teeth come through, root canal treatment, fillings and X-rays, with no personal contribution and nothing counting towards the statutory deductible (zorginstituutnederland.nl, retrieved 4 October 2026). Braces sit outside that unless they qualify as specialised dental care.
From 18, the entitlement collapses to a short list: surgical dental care, X-ray examination and removable dentures, plus specialised dental care where a serious developmental disorder or abnormality of the mouth is involved, a category under which orthodontics and implants fall (rijksoverheid.nl, retrieved 4 October 2026).
Two contributions survive inside the basic package and catch people out. For a full removable denture you pay 25 percent of the cost yourself; for an implant-retained denture, 10 percent for the lower jaw and 8 percent for the upper (zorginstituutnederland.nl, retrieved 4 October 2026). From 18 the statutory deductible also applies to whatever the basic package covers.
Everything else — check-up, cleaning, filling, crown, bridge — is a private bill unless you buy a module.
The two numbers that decide the whole question
A dental module is described by a percentage, sold on the percentage, and limited by something else entirely.
Every module has an annual ceiling: the most it will pay out in a calendar year, whatever the percentage says. a.s.r. publishes its range openly (asr.nl, retrieved 4 October 2026):
| Module | Reimbursement | Annual maximum |
|---|---|---|
| TandBewust | 75 percent, basic treatments only | 250 euros |
| TandGoed | 75 percent, including X-rays, crowns and bridges | 250 euros |
| TandBeter | 100 percent, including X-rays, crowns and bridges | 250 euros |
| TandBest | 100 percent basic, 75 percent extensive | 500 euros |
| TandPlus | 100 percent basic, 75 percent extensive | 750 euros |
a.s.r. also states that orthodontics is not reimbursed from the dental module but from the general supplementary insurance (asr.nl, retrieved 4 October 2026). Other insurers structure modules differently; the two-number logic is the same everywhere.
One structural point sits above all of this. At a.s.r. the dental cover is not part of the supplementary insurance at all: the insurer writes that “Tandzorg is niet verzekerd vanuit een aanvullende verzekering”, so the dental levels above have to be bought as a separate tandartsverzekering (asr.nl/zorgverzekering/aanvullende-verzekering, checked 4 October 2026). Those packages start from 10 euros a month, and reimbursement runs from age 18 (asr.nl/zorgverzekering/tandartsverzekering, checked 4 October 2026). Budget for the dental premium on top of the supplementary premium, not inside it.
Read the ceiling first. It is the most the product can ever return in a year, and it is the number to put next to twelve months of premium. If the ceiling is not comfortably above the annual premium, the module cannot pay for itself even in your worst year — it can only reduce the loss. Figures above are for the current policy year as published on 4 October 2026 and are revised annually, so check the version on sale.
What a treatment is allowed to cost
You cannot do the arithmetic without prices, and Dutch dental prices are not a free market. The Nederlandse Zorgautoriteit sets maximum tariffs for mondzorg, published per treatment code in its annual prestatie- en tariefbeschikking for dental and orthodontic care. For 2026 the NZa announced that orthodontic tariffs fall by 11.18 percent from 1 January 2026 and that an average dentist visit is 1.12 percent cheaper than in 2025 (nza.nl, retrieved 4 October 2026). We quote no per-treatment amounts here: look them up in the current NZa tariff list for mondzorg, because that is the document your dentist bills from.
The second lever is the quote. Under the NZa rules a dentist must give you a quote before any treatment costing more than 250 euros, and above 500 euros that quote must always be in writing (nza.nl, retrieved 4 October 2026). Ask for it with the treatment codes.
So: treatment plan first, quote second, cover third. Not the other way round.
Running your own numbers
With an estimate in hand, the calculation takes ten minutes. No invented figures are needed, only yours.
- Write down the treatment plan for the next twelve months. Two check-ups, a cleaning, whatever the dentist has flagged.
- Price it from the estimate or the NZa tariff list, per treatment code.
- Take a candidate module and apply its percentage to the eligible items only. Read what the module excludes; at a.s.r., for example, orthodontics sits outside the dental cover.
- Cap the result at the module’s annual ceiling. This is the reimbursement.
- Subtract twelve months of that module’s premium. What is left is what the module is worth to you this year.
- Repeat for the level above and the level below. The middle option is not automatically the right one.
Two warnings about step 5. The premium is per person, so a household multiplies it. And if you join a module mid-year, ask the insurer how the premium and the annual ceiling are applied for that first year.
The module comes out ahead when your plan is heavy and behind when it is light; the calculation shows which one applies to you.
Compare the a.s.r. dental modules and conditions
A collective discount changes step 5. UnitedConsumers’ health policies are “UnitedConsumers door VGZ”, put together with VGZ, with which it has worked since 2006. Participants get 20% off the aanvullende verzekeringen and the tandartsverzekeringen (unitedconsumers.com/over-ons/samenwerkingen/vgz, checked 4 October 2026). A fifth off the premium moves the break-even in the calculation above by about a fifth of a year’s premium, which is enough to flip a marginal answer — but only against the VGZ dental modules, so compare the ceilings and exclusions first and the discount second. The UnitedConsumers pages quoted here are in Dutch.
The layer where they are allowed to say no
This is the part that separates dental cover from the basic insurance, and it is the reason the season has a deadline.
Insurers must accept everyone for the basic package. The supplementary layer works differently: rijksoverheid states that the insurer sets the conditions itself and “mag u weigeren, maar in de praktijk komt dit bijna niet voor” — may refuse you, though in practice this almost never happens. The same page confirms three things worth knowing before you apply (rijksoverheid.nl, retrieved 4 October 2026):
- A waiting period is permitted. The example given is a new crown reimbursed only after six months.
- The premium may be higher if you are older, or if your basic insurance is elsewhere.
- There is no statutory deductible on a supplementary policy; that belongs to the basic package.
Refusal is rare according to rijksoverheid, but it is allowed, and so is a waiting period. Read the specific module’s conditions; our guide to reading a Dutch policy shows where these clauses sit.
The consequence: buying a module the month before major work is not a strategy. Either the waiting period blocks it or the ceiling absorbs it.
Why 31 December is a genuine deadline
The switching rules are simple and they are published. Take out a new health insurance policy by 31 December and your new insurer cancels the old one automatically. Cancel yourself by 31 December and you have until 1 February to take out a new policy, with cover backdated to 1 January (rijksoverheid.nl, retrieved 4 October 2026). Insurers publish their premiums and conditions for the new year before 12 November (rijksoverheid.nl, retrieved 4 October 2026).
For the basic package, missing the window is inconvenient. For dental cover it is worse, because there is no acceptance duty on the supplementary layer: a module you cancel is not guaranteed to be available again on the same terms, and one you join may start with a waiting period. That is the asymmetry to plan around. Two related pieces cover the timing rather than the product: our January 2027 deadline article and the budget insurer comparison.
Paying for it yourself
The alternative is no dental insurance at all, and depending on your numbers it can be the better arithmetic. Set up a standing order into a separate account for the amount you would have paid in premium, and pay the dentist from it. No ceiling, no waiting period, no annual review, and the balance is yours if you leave the country. The downside is timing: a pot that has run for four months does not cover a crown in month five, and it does not cover a teenager’s orthodontics, where the cost is large and compressed.
A reasonable split. Self-insure the routine — check-ups and cleaning are predictable and modest. Insure what you cannot absorb, if a module actually covers it and the ceiling is high enough to matter. Buying a module purely to get check-ups reimbursed is usually paying an insurer to hold your money for a year.
If you have no dentist yet, fix that first: the treatment plan the calculation needs comes from the first appointment. Our English-speaking dentist guide covers finding a practice; the add-ons comparison puts dental next to physiotherapy.
Final thoughts
Do this in order. Book the check-up you have been putting off, ask for the treatment plan and an itemised estimate with the codes, then price two or three modules against it using the percentage and the ceiling together.
Then wait for the published premiums before committing, and make the decision before 31 December — because the dental layer is the one where the insurer, not you, decides whether the door is still open.

This explains how Dutch dental cover is built; it is not insurance advice. Module names, percentages and ceilings are revised every year, and no 2027 premium figures appear here because they had not been published.
Frequently Asked Questions
What does Dutch basic health insurance still pay for at the dentist after 18?
Very little of what you would call going to the dentist. Rijksoverheid lists the adult entitlement as surgical dental care, X-ray examination and removable dentures, plus specialised dental care where there is a serious developmental disorder or abnormality of the mouth, a category under which orthodontics and implants fall (rijksoverheid.nl, retrieved 4 October 2026). Rijksoverheid states that the periodic check-up is not in the basic package from 18, and Zorginstituut Nederland that most dental care is no longer reimbursed from that age. For a full removable denture you pay a personal contribution of 25 percent of the cost; for an implant-retained full denture it is 10 percent for the lower jaw and 8 percent for the upper (zorginstituutnederland.nl, retrieved 4 October 2026). The statutory deductible applies to what the basic package does cover from age 18.
How does the annual ceiling on a dental module actually work?
A dental module reimburses a percentage of eligible treatment costs, and stops entirely once the yearly total reaches the ceiling written into that module. Both numbers matter. a.s.r., for example, publishes five levels: TandBewust, TandGoed and TandBeter all cap at a maximum of 250 euros a year, TandBest at 500 euros and TandPlus at 750 euros, with 75 or 100 percent reimbursement depending on the level and the type of treatment (asr.nl, retrieved 4 October 2026). The practical consequence is that the ceiling, not the percentage, sets the most the module can ever return to you in a year. Once you know the ceiling, compare it with twelve months of the module premium: if the ceiling is not comfortably above the premium, the module cannot pay for itself even in a bad year.
Can a Dutch insurer refuse me dental cover or make me wait?
Yes to both, and this is the difference between the basic and the supplementary layer. For supplementary insurance rijksoverheid states plainly that the insurer sets its own conditions and "mag u weigeren, maar in de praktijk komt dit bijna niet voor" — it may refuse you, though in practice this almost never happens. The same page confirms that an insurer can apply a waiting period, giving the example that a new crown is only reimbursed from the dental module after six months, and that the premium may be higher if you are older or if your basic insurance sits with a different insurer. There is no statutory deductible on a supplementary policy (rijksoverheid.nl, retrieved 4 October 2026). The page says an insurer can apply a waiting period, so read the conditions of the specific module rather than assuming either way.
Where can I look up what a dental treatment is allowed to cost?
The Nederlandse Zorgautoriteit sets maximum tariffs for mondzorg, published per treatment code in its annual prestatie- en tariefbeschikking for dental and orthodontic care. Those maximums are what a Dutch dentist may charge, and the NZa announced that from 1 January 2026 orthodontic treatment tariffs fall by 11.18 percent while an average dentist visit is 1.12 percent cheaper than in 2025 (nza.nl, retrieved 4 October 2026). The NZa rules also cover the quote: for treatments costing more than 250 euros the dentist must give a quote before treatment, and above 500 euros that quote must always be in writing (nza.nl, retrieved 4 October 2026). Ask for the treatment codes and you can price the plan before you insure it.
Is 31 December really a deadline for dental cover?
It is the practical one. If you take out a new health insurance policy by 31 December, your new insurer cancels the old one for you automatically. If you cancel yourself by 31 December, you have until 1 February to take out a new policy, with cover backdated to 1 January (rijksoverheid.nl, retrieved 4 October 2026). The reason it matters more for dental than for the basic package is that the basic package carries an acceptance duty and the supplementary layer does not, so a module you drop in December is not guaranteed to be available on the same terms later, and a waiting period may apply to a module you join. Insurers publish premiums and policy conditions for the new year before 12 November (rijksoverheid.nl, retrieved 4 October 2026), which leaves roughly seven weeks to decide.
Is it smarter to save the money myself instead?
It can be, depending on your own numbers. The comparison is not complicated: twelve months of module premium against the reimbursement you would realistically claim, remembering that reimbursement is capped by the annual ceiling. If the module can never return much more than it costs, a standing order into a separate savings account does the same job with no ceiling, no waiting period and no annual review. Where self-insuring goes wrong is with a known, large, planned course of work, or with orthodontics for a teenager, where the bill lands in one year rather than spreading evenly. Price both before you decide.
