What this is about

A professional dental cleaning — at this practice often abbreviated as PZR (professionelle Zahnreinigung) — is a supplementary cleaning carried out by trained practice staff. It reaches the places where a toothbrush, floss, and interdental brush at home struggle to go: hardened tartar deposits on inaccessible surfaces, fine discolorations, and buildup along the gumline. The goal isn’t an aesthetically perfect photo — it’s a baseline from which your home care can work fully again. ¹

Anyone scheduling a PZR for the first time often wonders how the appointment unfolds, how long it takes, and what will feel different afterward. This article gives a calm orientation. The exact steps depend on your individual findings.

Before the appointment

A PZR doesn’t need any special preparation. You can eat and drink as on any ordinary appointment day, and brush your teeth as usual.

Please let us know before we begin if you take blood-thinning medication, are pregnant, are on immunosuppressive therapy, or have recently had joint surgery. We’ll then discuss whether the appointment fits as planned, or should be adjusted briefly — adjustments like these are routine, not a sign of a problem.

In most cases the PZR takes between 45 and 60 minutes. For first visits, more pronounced discoloration, or particularly many interdental spaces, it can run a little longer — we’ll mention that before we start so your schedule isn’t squeezed.

Who benefits the most:

For most adults, a PZR once or twice a year makes sense. Higher individual risk often warrants shorter intervals. Typical cases include:

• People with fixed or removable orthodontic appliances — brackets and wires encourage buildup at spots that are hard to brush at home.
• Patients with exposed tooth necks — the bare surfaces are more vulnerable to caries than enamel.
• After completed periodontitis treatment — regular cleaning is a central pillar of supportive periodontal therapy here. ²
• During pregnancy — the hormone-driven increase in gum sensitivity is well managed with consistent cleaning.
• With dry mouth caused by medication or certain chronic conditions — reduced saliva flow tilts the balance toward deposits.

We discuss the right interval for you at the session — a one-size-fits-all schedule would be a shortcut that doesn’t do the topic justice.

The five-step procedure

1. Findings

We start with a short look inside the mouth. Using a fine probe and a mirror, we examine your teeth and gums. At a few spots we measure the depth of the gum pockets — a brief, routine step in prevention. Alongside that comes a conversation about what you’ve noticed yourself: sensitive spots, gums that bleed when you brush, small changes since the last appointment.

This first part isn’t just diagnostics. It also shapes how we work in the next steps — how much time we’ll need for which areas, and where we’ll focus particular attention.

2. Cleaning the tooth surfaces

Next, soft and hard deposits on the visible tooth surfaces are removed. Hard deposits — tartar — settle especially behind the lower incisors and on the outer surfaces of the upper molars, that is, near the salivary glands.

For this we generally use an ultrasonic device with a fine tip, which loosens the deposits through high-frequency vibration, along with hand instruments for particularly delicate spots. Both work gently. Some patients find the vibration unfamiliar, others barely notice it — that varies from person to person and says nothing about how much deposit is actually present.

3. Cleaning the interdental spaces

In the third step we focus on the spaces between the teeth. This is where deposits collect that even very good home care can’t completely reach. We use interdental brushes matched to the gap width, floss, or fine polishing strips.

If you don’t yet do interdental care at home, or aren’t sure which size fits, this step is a good moment to look at it together. We’re glad to show you which brush size goes with which gap — and to send you home with a matching sample for the days ahead.

4. Polishing

After cleaning comes the polish. There’s a practical reason for it: smooth surfaces give deposits fewer footholds than rough ones. We use a fine polishing-paste set and small rotating attachments. Most people find this part pleasant — similar to brushing at the end of a thorough cleaning.

5. Fluoride application

To finish, we apply a fluoride varnish or gel to the teeth. This takes only a few minutes and is intended to re-strengthen the enamel after cleaning. You should then avoid eating and drinking for about 30 minutes so the varnish can take effect.

With that, the appointment is over. We talk through what we saw, whether any of it deserves further observation, and when the next appointment makes sense.

Afterward — the first hours

In the first day or two after a PZR, the gums can feel sensitive, especially where there was more deposit before. Some patients also report briefly more sensitive teeth with cold or hot drinks. Both usually subside within a few days.

What helps:

• Switch to a soft toothbrush for a few days if you normally use a medium one
• Briefly avoid very cold or very hot food
• Keep brushing twice a day as usual — your home routine stays unchanged
• Skipping staining drinks (red wine, coffee, black tea) for the first hours after the session is worth it for the freshly polished surfaces

If complaints persist over several days or get worse, please call us. That isn’t the usual course, but it’s best understood in a short conversation.

How often a PZR makes sense

The usual recommendation in Germany is once to twice a year. ¹ With higher individual risk — see the Who benefits the most section above — shorter intervals make sense. IQWiG, Germany’s independent health-research institute, situates the value of a PZR as a complement to home care, naming both what the evidence supports and where it remains open:

Costs and reimbursement

In Germany, a PZR is classified as an individual health service (IGeL, individuelle Gesundheitsleistung). Germany’s statutory health insurers (GKV, gesetzliche Krankenversicherung) don’t cover it as a standard benefit — it isn’t part of the GKV catalog. Many funds, however, offer contributions through their bonus programs (Bonusprogramme), in some cases up to full coverage; a few even settle directly with the practice if you’re enrolled. ⁴ Private insurance and the civil-servant Beihilfe scheme often reimburse a PZR under your individual policy.

What to know about billing:

The three questions German patients ask us most often, briefly answered:

• Statutory insurance without a bonus arrangement: you pay the patient share. The amount follows the German dental fee schedule (Gebührenordnung für Zahnärzte, GOZ) and lies, for a full adult PZR, within a usual range that we’ll tell you before the appointment.
• Statutory insurance with a bonus or contribution: many funds subsidize at least one PZR per year. A quick look at your insurance app or benefits overview will show — we’re happy to help if you can’t find the line.
• Private insurance or Beihilfe: most policies reimburse one to two PZRs per year under preventive care. A formal treatment-cost plan (Heil- und Kostenplan) is usually not needed here; a short cost estimate is often enough.

We’ll always tell you the expected patient share before we begin the session. If effort and therefore cost would change during the appointment, we pause and discuss it.

If you’d like to schedule an appointment

If you’re thinking about scheduling, do get in touch. A PZR can also be combined with a routine check-up — many patients find that easier on their day, and it often fits well in our schedule.

You can request an appointment through the contact form or by phone during our opening hours. An overview of our preventive services is available under Preventive care.
