Your Child's Free Dental Checkups: Z1-Z6 and the Bonusheft System

The Official Rule

If another parent has mentioned “FU1 to FU3” dental checkups, worth knowing upfront: that terminology describes an older system, and something genuinely changed rather than just being renamed. Per the Bundeszahnärztekammer (BZÄK), as of January 1, 2026, Germany’s statutory health insurance covers six dental early-detection exams, Z1 through Z6, for every child from 6 months old through the end of their 6th year, specifically to catch early childhood caries, one of the most common chronic conditions in young children, before it takes hold.

The same reform connects this system directly to a booklet your family already carries. As covered on our Gelbes Heft (U-Heft) page, since January 1, 2026, Z1-Z6 results are recorded directly in the yellow Kinderuntersuchungsheft alongside the U1-U9 pediatric checkups, per the KZVB (Kassenzahnärztliche Vereinigung Bayerns). In practice, that means bringing the same yellow booklet to the dentist that you’d bring to the Kinderarzt, not a separate dental-specific record. Each Z-exam checks whether teeth are developing age-appropriately and screens for caries risk, tooth misalignment, or a shortened lip frenulum, and includes guidance on oral hygiene, nutrition, and fluoride. Children up to 33 months old get an additional, specific benefit: fluoride varnish applied directly at the dental practice, twice per calendar half-year.

Turning 6 doesn’t end covered dental care, it just changes shape. According to TK, a major statutory insurer, in its own English-language guidance, children ages 6 through 17 continue getting a covered checkup twice per calendar half-year regardless of the Z1-Z6 schedule being finished. Fissure sealants on back molars become covered too, where medically necessary.

Around age 12, checkups start being recorded somewhere new: an actual Bonusheft. Per the KZBV’s own explanation, this booklet, separate from the Gelbes Heft, applies to every statutory-insured person, adults included, and gets a dentist’s stamp at each regular checkup attended. The financial payoff comes later in life: an unbroken 5-year record raises the statutory contribution toward dentures or crowns from a 60% baseline to 70%, and a full 10 unbroken years raises it to 75%. Since the record has to be genuinely unbroken to count, keeping the booklet itself safe, and actually attending the twice-yearly checkups even once early dental problems aren’t a concern, is worth the small ongoing effort.

What Real People Say

Guidance aimed at parents consistently emphasizes starting earlier than instinct suggests. kindergesundheit-info.de’s official federal guidance frames the first dental visit around the first baby tooth, generally between 6 and 9 months old, well before many parents assume a dentist visit is necessary, precisely because early childhood caries can already be taking hold by the time a first tooth is visibly affected.

Practical tips that come up repeatedly in guidance for a child’s first dental visit: choose a morning appointment when children tend to be more alert and less tired, bring a favorite stuffed animal so your child can “practice” on it first, and be mindful of your own tone, children pick up on a parent’s anxiety about dental visits more than on the visit itself.

Step by Step

1. Book your child’s first dental visit around the first baby tooth, generally 6 to 9 months old, don’t wait until it feels urgent.
2. Bring the yellow Gelbes Heft (U-Heft) to the dental appointment, results are recorded there directly since January 1, 2026.
3. Track the Z1-Z6 age windows against your child’s actual age, rather than scheduling only when convenient, to stay within each covered window.
4. From age 6, keep the twice-yearly checkup rhythm going, coverage continues even though the Z-schedule has finished.
5. From around age 12, keep the Bonusheft itself safe and bring it to every checkup, an unbroken record pays off financially much later in life.

Compliance Note

This page explains the general structure of Germany’s child dental prevention system as of the January 2026 reform, but exact coverage details and practice-level scheduling can vary. For your child’s specific situation, confirm current details directly with your Kinderzahnarzt or your statutory health insurer.
