What is professional teeth cleaning?
What does PZR mean?
PZR is the German abbreviation for professional teeth cleaning. Specially trained dental professionals remove soft and hard deposits and external staining. Tooth surfaces, spaces between teeth and accessible areas along the gumline are cleaned. Professional cleaning supplements daily oral hygiene and forms part of individually tailored preventive care. [1] [2]
Soft bacterial deposits are called plaque or biofilm. When minerals accumulate, hard calculus forms, which can no longer be removed with a toothbrush or dental floss. Stains from coffee, tea or tobacco, by contrast, are deposited pigments. Cleaning, polishing and fluoride application therefore serve different purposes. [1] [6]

What happens during professional teeth cleaning?
The procedure depends on the condition of the teeth and gums. It usually includes the following steps:
- Discussing findings and care: Deposits, sensitive areas and difficulties with cleaning at home are taken into account.
- Removing deposits: Hand instruments, sonic or ultrasonic devices and, where appropriate, air-polishing devices are used as needed.
- Finishing the surfaces: Depending on the situation, the tooth surfaces are polished and fluoride is applied.
- Tailoring home care: You receive advice on cleaning even hard-to-reach areas at home.
As a general guide, professional teeth cleaning often takes about 45 to 60 minutes, or longer if more work is required. Confirm with the practice how much time is planned for your appointment. [1] [3]
Cleaning, polishing and fluoride application serve different purposes. Cleaning removes deposits; polishing smooths the treated surfaces. Fluoride helps protect against tooth decay. The steps and materials used depend on the findings. Thorough cleaning therefore cannot be judged solely by whether a particular device was used or whether the teeth feel especially smooth afterwards. [1] [6]
Three methods of professional teeth cleaning
Sonic and ultrasonic devices loosen calculus through vibration. Air polishing removes soft deposits and staining using air, water and cleaning powder. Hand instruments provide targeted additional cleaning. The material and area of use must suit the findings; not every instrument or powder is equally suitable for every surface. [3]
Cleaning deep gum pockets forms part of targeted periodontitis treatment and is not the same as routine professional teeth cleaning.
How does it differ from other treatments?
Calculus removal: This removes hard deposits. Professional teeth cleaning also includes soft deposits, external staining and finishing the surfaces, among other steps. Calculus can therefore be removed professionally without a full professional cleaning. [4]
Preventive care: This umbrella term describes preventive measures. Examples include oral hygiene, individual advice and check-ups. Professional teeth cleaning is one possible part of this approach. [1]
Periodontitis treatment and SPT: Targeted cleaning of affected deep gum pockets is part of periodontitis treatment. Supportive periodontal therapy (SPT) is the structured aftercare following this treatment. Routine professional teeth cleaning replaces neither the treatment nor SPT. [5] [2]
Dental check-up: An examination assesses whether there is disease or another need for treatment. Cleaning serves a different purpose. The two services can be coordinated, but they are not automatically the same. New symptoms should therefore be mentioned even if a cleaning appointment is already booked. [4]
When can professional teeth cleaning be useful?
Whether professional teeth cleaning is useful depends on the individual findings. It can supplement cleaning at home where deposits remain in hard-to-reach areas. With implants, dental restorations or fixed orthodontic appliances, cleaning is adapted to the particular situation. External staining can often be removed at the same time. [1]
However, professional cleaning does not guarantee permanently healthy teeth. The additional long-term benefit of regular cleaning appointments for people whose oral health is already good has not been clearly established scientifically. Daily oral hygiene and dental care based on personal risk remain crucial. [6]
If your gums bleed repeatedly, the cause should be investigated first. Gum inflammation (gingivitis) or periodontitis requires appropriate treatment planning.
Professional cleaning in particular circumstances
Implants, restorations and fixed braces: Deposits can remain at margins and in hard-to-reach areas. Cleaning and home-care aids are adapted accordingly. Discuss with the team how to reach these areas effectively in daily care. [1] [3]
Pregnancy: Hormonal changes can increase gum inflammation. Tell the practice about your pregnancy so that examinations, advice and cleaning can be planned appropriately. For a planned professional cleaning, the DG PARO specifically identifies the second trimester. [7]
Before the appointment: Tell us about relevant conditions, allergies, medication and marked sensitivities. This helps the team tailor your treatment. [3]
How often is professional teeth cleaning useful?
One or two appointments a year can serve as a guide. With a higher risk of disease, different, potentially shorter intervals may be appropriate. The recommendation should reflect the findings and be adjusted when these change. After periodontitis treatment, the individual SPT plan is the guide. [1] [5]
Your own oral care remains crucial between appointments. Alongside a toothbrush, suitable interdental brushes or dental floss can help. The choice depends on the spaces between your teeth and, where applicable, restorations or implants. Practical instruction makes the recommendations easier to follow in daily life. Your next professional cleaning is no substitute for having new symptoms or recurring bleeding gums assessed promptly. [1] [4]
What does professional teeth cleaning cost?
The cost depends on the extent and difficulty of the cleaning. Ask for the anticipated work and cost to be explained beforehand. Professional teeth cleaning is not a standard German statutory health insurance benefit; many insurers offer voluntary contributions. Private health and supplementary dental insurers reimburse according to the policy. Ask your insurer directly about the current terms. [1]
This differs from calculus removal alone: German statutory health insurance generally covers this once a year, or more frequently for certain eligible people. [6]

Andreas Haas, M.Sc., and our team discuss which preventive measures suit your teeth and gums. You can find our professional teeth cleaning service under Preventive care at smileDentity.

Professional teeth cleaning and targeted periodontitis treatment serve different purposes.
Frequently asked questions about professional teeth cleaning (FAQ)
Cleaning can be uncomfortable around sensitive tooth necks or inflamed gums. Mention symptoms beforehand. The team adapts the treatment; local anaesthesia may be considered if needed. Temporary irritation or bleeding is possible. [6] [3]
Instruments and polishing products are intended to remove deposits selectively and are chosen to suit the tooth surface. Nevertheless, a blanket guarantee of complete freedom from risk is inappropriate: long-term adverse effects have not been sufficiently investigated. Sensitive tooth necks, implants and restorations should be taken into account beforehand. [6] [3]
Removing external staining can make teeth look brighter. Their natural colour is not deliberately changed as it is with bleaching. New stains may develop later. [1] [6]
Yes, following individual consultation with your dentist. The DG PARO identifies the second trimester as a suitable period for a planned professional cleaning. Tell the practice about your pregnancy. Symptoms or bleeding gums should be assessed regardless. [7]
No. Affected deep gum pockets require targeted periodontitis treatment. Subsequent supportive periodontal therapy (SPT) includes follow-up checks and further individually tailored measures. Routine professional cleaning alone does not replace this treatment and aftercare. [2] [5]
