Talk to us first
If you have a complaint or concern, please call us at 0297 569 965 or email info@tandartspraktijkzijdelwaard.com. We genuinely want to hear from you and discuss your concern personally at the practice.
You can also submit a written complaint by post to:
Tandartspraktijk Zijdelwaard
Anne Franklaan 1
1422 HC Uithoorn, the Netherlands
It can happen
It can happen that, despite our efforts, you're not satisfied with a treatment or situation at the practice. We'd like to discuss it with you so we can learn from your feedback and find a fair solution together.
Independent complaints officer via the KNMT
If we can't resolve it together, or you'd prefer an independent third party — our practice is a member of the KNMT (Royal Dutch Dental Association). The KNMT provides a free, independent complaints officer who can mediate between you and the practice.
More information on the official complaints procedure: knmt.nl/patient/klacht-over-uw-tandarts.
Step by step
- Discuss your complaint first with your dentist or another team member.
- If unresolved, submit a written complaint to the practice — email or letter.
- If you're still not satisfied after our written reply, contact the KNMT complaints officer.
- If that mediation doesn't lead to a resolution, the case can be submitted to the official Dutch dental disputes committee (Geschilleninstantie Mondzorg).
What you can expect from us
- Acknowledgement within 3 working days
- A substantive response within 14 working days
- Full confidentiality — your complaint will not affect your treatment
