Quick answer: An intact amalgam filling does not need automatic removal because the EU has restricted new use of dental amalgam. The rule concerns future placement; it does not instruct dentists to replace existing restorations. Whether to monitor, repair or renew a filling depends on the tooth, the restoration margins, symptoms and examination findings.

Key points
- EU rules generally restrict new dental amalgam treatment from 2025, with a narrowly worded patient-specific medical exception.
- An existing, clinically sound amalgam filling does not need removal just because new use has been restricted.
- A dentist assesses the margin, possible decay or cracks, symptoms, bite and remaining tooth structure together.
- Monitoring, a local repair and full replacement differ in tooth removal, effort, visits, care and limits.
- Treatment choice and possible German insurance costs depend on the findings and the plan discussed before care.
What the EU phase-out means for existing fillings
Since 1 January 2025, dental amalgam has generally not been used for dental treatment in the EU. The regulation allows a narrow exception when a dentist considers its use strictly necessary because of a patient’s specific medical needs. This rule concerns a future treatment using the material.
The phase-out does not instruct dentists to remove fillings that are already in place. Germany’s National Association of Statutory Health Insurance Dentists (KZBV) says intact amalgam fillings do not need to be replaced; the DGZMK and DGZ also advise against preventive removal of intact fillings. Symptoms or an abnormal finding still need individual assessment.
- A restriction on new use does not diagnose an existing restoration.
- A clinically sound filling does not need replacement only because of its colour or material.
- The exception for new amalgam treatment is a specific medical decision.
A dental check assesses the restoration and the tooth
A silver or dark appearance alone cannot show whether a filling is sound or whether the tooth needs treatment. A dentist may assess the filling margins, cracks, chips, new decay, remaining tooth structure, bite and nearby gums. An X-ray is considered only when it can help answer a specific diagnostic question.
Describe whether the tooth hurts when chewing, reacts to cold, heat or sweet foods, or aches without a trigger, and when the change began. A normal-looking surface cannot rule out every problem; a dark edge does not automatically mean the whole filling should be replaced.
- Describe symptoms, visible changes and any previous findings.
- Have margins, cracks and possible decay assessed after examination.
- Use imaging when it is relevant to the question being checked.
Monitoring, repair and replacement answer different findings
If a filling is clinically sound, the practice may monitor it during routine reviews. This keeps the existing restoration in place and avoids treatment without an identified need. A small, local defect may sometimes be repaired, depending on the shape of the damage and the tooth; an examination is needed to decide whether that is suitable.
Full replacement removes the existing restoration so the tooth can be assessed for a new one, and some additional tooth structure may be lost. If the defect is larger or the tooth is more weakened, a direct filling, inlay, onlay or crown may be discussed. None of these choices is best for every tooth.
The number of visits depends on whether the plan is monitoring, a local repair or a more extensive restoration. Ask which steps are proposed, how the options compare for your findings, and what care or review will be useful afterward.
- Monitoring relies on a clinically adequate filling and suitable reviews.
- Repair may be considered for a limited defect when the situation allows it.
- Full replacement may involve more tooth removal and additional treatment steps.
- Compare the findings, tooth preservation, effort, visits, cleaning and limits.
Material and costs belong in the plan before treatment
When replacement is clinically indicated, material choice depends on factors such as the defect’s size and location, the remaining tooth structure and the clinical situation. The KZBV describes self-adhesive filling materials as part of Germany’s no-extra-charge statutory care for back teeth since 2025; other options and coverage can differ with the findings and insurance.
The KZBV says German statutory insurers generally do not cover replacement of an intact filling without a medical reason. Before treatment, discuss the finding, why replacement is proposed, alternatives, likely visits and written cost information. A written additional-cost agreement should be available before care when one is required.
- Ask which finding supports replacement and what the clinical reason is.
- Request a written explanation of standard care and any additional costs.
- Compare material, appointments, aftercare and review before choosing.
Symptoms and warning signs need timely assessment
A loose, broken or partly lost filling should be assessed by a dentist. Arrange a check if sensitivity increases, chewing hurts or your bite feels different. These signs do not automatically mean the entire filling needs replacement.
Severe or quickly worsening pain, swelling, fever or pus calls for urgent dental advice. Difficulty breathing or swallowing, or rapidly increasing swelling of the face or neck, needs immediate medical help. Online information cannot determine the cause or urgency for an individual tooth.
An appointment in Konstanz can clarify the individual finding
Before an appointment, note when the filling started to bother you, what triggers symptoms and whether older X-rays or treatment records are available. Ask which finding supports repair or replacement, what alternatives fit, and what would change if the filling is monitored for now. Patients from Konstanz and Kreuzlingen can describe the question in advance through the practice contact page.

FAQ
Does the EU amalgam phase-out mean my old filling must be removed?
No. The EU rule generally concerns new use of dental amalgam and does not instruct dentists to remove fillings already in place. KZBV and DGZMK/DGZ advise against preventive removal of intact fillings. Symptoms or an abnormal margin should be assessed before a next step is chosen.
How can a dentist assess an older amalgam filling?
The dentist may examine the margins, chips, possible decay, the tooth and your symptoms. Colour alone does not prove a defect. An X-ray may help when it answers a specific question. Even if you feel little, the restoration can only be assessed through an examination.
Can removing an amalgam filling release more mercury?
DGZMK/DGZ notes that removal can cause a temporary increase in release. This is one reason not to remove a clinically intact filling without an indication. It does not mean necessary care should be avoided. Ask why replacement is recommended and how the procedure will be planned.
What materials may be used instead of amalgam?
Depending on the defect, options may include a direct filling or, when more tooth structure is missing, an inlay, onlay or crown. Size and location, remaining tooth structure, bite and cleaning access affect the choice. No material is suitable for every tooth.
When does a damaged filling need urgent attention?
A loose or broken filling should be assessed by a dentist in a timely way. Increasing pain, swelling, fever or pus makes advice more urgent. Difficulty breathing or swallowing, or rapidly increasing facial or neck swelling, needs immediate medical help.
