Dental supplement
Dental insurance — is it worth it?
What GKV actually pays vs. real dentist bills, and when a supplement meaningfully closes the gap.
What does GKV cover at the dentist?
For dental prosthetics the GKV pays only a fixed subsidy toward the so-called standard solution — 60 % of the cheapest viable treatment, rising to 70 % after 5 years and 75 % after 10 years of regular check-ups (proven via the bonus booklet). A simple metal crown is therefore covered, an all-ceramic crown for a visible front tooth is not. Implants, inlays, and higher-grade materials count as private services — you pay the difference in full. For a single implant that easily means €2,500–4,000 out of pocket per tooth.
For full routine treatment GKV reimbursement looks much better: dental cleaning (within the annual check-up framework), amalgam or composite filling on a back tooth, root canal in most cases and check-ups are fully covered. Pain treatment and emergencies are also fully included. So GKV pays for medical basic care — it does not pay for aesthetic, comfort or premium-material choices.
A concrete calculation illustrates the gap: a three-tooth bridge in standard execution costs around €1,800. The GKV standard reimbursement is around €480 (60 % of an €800 fixed subsidy) — the insured pays €1,320 themselves. For a high-quality all-ceramic bridge the total is €3,500, GKV stays at €480, out-of-pocket: €3,020. A good supplemental policy fills exactly this gap and covers 80–100 % of the personal share — the personal cost drops to €0–600.
How does dental supplement work?
Dental supplemental insurance is a private supplemental policy that runs parallel to GKV. In case of a claim the insurer reviews the dentist’s bill, deducts the GKV share and reimburses an agreed percentage of the personal share — typically 80 % or 90 %, in premium tariffs 100 %. The payout goes directly to you, not the dentist. You submit the bill to the insurer (via app, email or post), receive reimbursement within 1–3 weeks, and the dentist is paid as usual. This two-step process gives you full control and is not possible for retroactive policies.
The reimbursement amount is contractually limited: most tariffs have a reimbursement percentage (e.g. 90 % of the total bill including GKV share) and a maximum annual sum (e.g. €1,500–3,000 in the first years, then unlimited). Important is whether the GKV share is included or not: tariffs reimbursing the "personal share" pay less than tariffs reimbursing the "total bill". For an implant at €3,500 with €700 GKV share the first variant pays 90 % of €2,800 = €2,520, the second 90 % of €3,500 = €3,150 — but after deducting the GKV share both leave the insured with the same net result of €2,520.
When applying, you fill out a health questionnaire — usually 5–15 questions on current dental health, planned treatment, prosthetics in upper and lower jaw, periodontitis, root canals. Truthful and complete answers are critical: false statements lead to benefit reduction or contract changes in case of claim. Small issues like an already-treated cavity are unproblematic; larger ones (planned implant work) result in either rejection or risk surcharges. An already-issued treatment plan generally makes the policy unobtainable.
What benefits are included?
A solid dental supplement plan reimburses 80–100 % of the total bill for prosthetics, including private upgrades, covers professional dental cleanings (PZR) at €80–150 per session twice a year, pays 80–100 % for inlays and root canals, and covers orthodontic treatment from indication grade KIG 1–2 (the GKV pays from KIG 3–5). Premium tariffs additionally waive the offset against the GKV subsidy, lowering your out-of-pocket cost even further.
Detailed benefit areas: prosthetics covers crowns, bridges, implants, dentures — the most expensive area and most relevant for supplemental insurance. Inlays are high-grade fillings of ceramic or gold not paid by GKV; good tariffs reimburse them at 80–100 %. Root canals are covered by GKV only for retainable teeth — for complex multi-canal treatments or difficult apicoectomies the supplemental policy steps in. Professional cleaning (PZR) is not in the GKV catalogue and costs €80–150 per session; premium tariffs cover 2 sessions a year fully.
Better tariffs also cover special services: functional analysis for jaw-joint disorders (CMD), pain treatment with laughing gas or general anaesthesia for anxious patients, medically-indicated bleaching, and aesthetic prosthesis materials (ceramic veneering in visible areas). These extras often cost just a few extra euros monthly and can save several hundred euros in personal share when actually used. When picking a tariff think about what is personally relevant — a top implant policy is overkill if no implants are planned.
Tariffs compared (budget vs. premium)
The market offers three tariff classes that differ markedly. Budget tariffs (€10–18/month) reimburse 70–80 % for prosthetics, often exclude implants and have low annual maximums (€500–1,000). Standard tariffs (€18–28/month) offer 85–90 % reimbursement, cover implants and have higher sublimits. Premium tariffs (€28–45/month) pay 100 %, without offsetting the GKV subsidy, with unlimited reimbursement after the first 3–5 years. The choice depends on life situation and risk tolerance — rule of thumb: for young, healthy teeth a standard tariff usually suffices; for compromised teeth premium pays off.
Don’t be guided by the monthly premium alone. A premium tariff at €35/month (€420/year) is cheaper than a standard tariff at €22/month (€264/year) if you have a claim every few years — the premium tariff covers several hundred euros more per claim. Over 20 years that can be several thousand euros of difference. On the other hand: with very healthy teeth and no significant damage, you’ll pay 20+ years of premium tariff with no return. An honest risk assessment is therefore more important than pure tariff comparison.
Important comparison criteria beyond pure premium: 1. Maximum reimbursement in the first 4 years — varies widely from €1,000 to €5,000 cumulative. 2. Offset of GKV subsidy — some tariffs count it as "already provided benefit", others don’t. 3. Sublimits per implant — some tariffs only pay up to €1,500 per implant, far from enough. 4. Waiting period and immediate-cover offers — some insurers waive the waiting period for an extra fee. 5. Premium development — some insurers raise rates 20–30 % after 5 years, others keep tariffs stable until age 70.
Waiting periods and health questions
Standard waiting period is 3–8 months, during which only accident-related work is reimbursed. In the first 3–5 years there is a benefit cap — typically €1,000 in year one, cumulating to €3,000 by year three, then unlimited. Treatment your dentist has already proposed or started is never reimbursed, even after the waiting period. Some plans advertise “immediate cover, no waiting" — read the fine print, since this usually only applies to preventive care and pain treatment.
Health questions when applying determine whether the application is accepted, capped with exclusions, or rejected. Typical questions: how many teeth are currently missing? Are teeth replaced by crowns, bridges or implants? Have root canals been done in the last 12 months? Is periodontitis treatment ongoing? Is treatment with an existing plan upcoming? Every "yes" triggers insurer review — sometimes with surcharges, sometimes with exclusions for specific teeth, in extreme cases with rejection.
A useful strategy: time the application between routine check-ups, ideally right after a "dental status unobtrusive" exam. If your dentist is preparing a treatment plan, it’s too late — the insurer asks explicitly, and false answers jeopardise the contract. Even a note in the bonus booklet ("recommended: implant region check") can be enough for later treatment to be excluded. Signing up with young, fully healthy teeth is the best strategy for a fully effective policy.
Orthodontics for children
GKV reimburses orthodontic treatment only for the most severe malocclusions (indication grade KIG 3–5) — for milder ones (KIG 1–2) parents must bear the full cost of typically €3,000–7,000. A good dental supplement for children fills this gap and covers 80–100 % of orthodontic costs from KIG 1. The policy costs €8–15/month for children and should be taken out before visible malocclusions appear — typically between ages 2 and 6, before milk teeth fall out.
Important to know: with GKV reimbursement for KIG 3–5 parents pay everything upfront and receive 80 % back after successful treatment completion (90 % for the second child). Treatment dropout or incomplete cooperation can reduce the share. A dental supplement covers this prefinancing immediately and pays regardless of treatment outcome. Additional private services like lingual technique (inside-mounted brackets) or aligners (e.g. Invisalign) — never covered by GKV — are also reimbursed.
Optimal strategy: take out the orthodontic supplement at preschool age, with a long claim-free wait period; then the child is fully insured at first orthodontic need (typically ages 9–13). For sibling families a family policy often pays off — including pregnancy and adult orthodontics; some tariffs offer discounts for the second insured family member. Watch out for tariffs labelled "orthodontics from KIG 3" — these only cover what GKV already pays and are practically worthless.
Sign up at the right moment
The sweet spot is between 20 and 35 — premiums are low, the waiting period is over by the time you need it, and your dental record is still clean. Budget €15–35/month per person for a strong tariff; a single implant case pays back 8–10 years of premiums. Before signing, ask honestly: how many of your teeth are already crowned or root-canalled? The more compromised your dental status, the higher both the expected benefit and the premium.
A concrete life-plan strategy: at 25 you take out a standard policy for €22/month. At 35 you receive your first PZR payouts — over 10 years you’ve paid €2,640 and received about €1,200 in PZR reimbursements, net premium of €1,440. At 45 you need an implant (cost €3,500, reimbursement €2,800) — at one go all premiums paid so far are more than recovered. At 65 the consequences of long-term wear show; several crowns and a bridge total €8,000, reimbursement around €6,500. Over the entire life: about €11,000 in premiums and around €14,000 in reimbursements — clearly positive.
Unfavourable: signing up only when the first treatment plan is on the table — it’s too late. Also unfavourable: signing up at 65 with compromised teeth — the premium then is €60–90/month, and the 8-month waiting period often collides with upcoming treatment. Anyone wanting a dental supplement as a senior should look for one without underwriting (such tariffs have higher premiums but lower hurdles) or use group rates via the health fund, which sometimes offer simplified acceptance.
Our recommendation
For most insured a standard policy (90 % reimbursement, around €22–28/month) at age 25–40 is the best solution — good price-value ratio, sufficient protection for typical life events, financially manageable. Premium tariffs are mainly worthwhile for families with orthodontic needs in children, insured with known dental problem family history, or those wanting high-quality all-ceramic care. Budget tariffs are mostly a savings illusion — when actual claim frequency hits, the personal share quickly costs more than the saved premium difference.
Specifically we recommend these steps: 1. Document your current dental situation at a check-up ("dental status stable"). 2. Compare three tariffs from different insurers — Stiftung Warentest, Finanztest or independent insurance brokers offer comparison tools. 3. Pay attention to long-term premium stability: insurers with tariff guarantees through age 70 are more reliable than cheap entry tariffs with steepening risk. 4. Read waiting periods and benefit caps carefully. 5. Sign up within 14 days — delaying increases the risk that an interim treatment complicates the contract.
An honest closing remark: a dental supplement is not for everyone. Anyone in good dental health, doing regular preventive care and not planning implants can also build a self-funded reserve — about €25 a month into a separate savings plan. Over 20 years that’s €6,000 plus interest, flexibly usable for any treatment. The advantage of insurance lies in protecting against unexpected events — accidents with tooth loss or hereditary conditions for dental problems. Anyone able to honestly assess their own risk profile makes the right call.
