🦷 I have a complaint about my dentist — bad work, overcharging — who decides?

Direct answer

Dentists are regulated like doctors: Collège médical (collegemedical.lu) — the dental chamber or its complaints body for Luxembourg — handles complaints about quality and conduct and can order a remedy; Service national d'information et de médiation dans le domaine de la santé (24 77 55 15) is the general patient-complaints route where the dentist is part of the public system. Money disputes — a bill far above the estimate, treatment not covered — go to CNS — Caisse nationale de santé (27 57 1), which checks the invoice against the tariff. Ask for the treatment plan and the invoice in writing first; most disputes are about what was agreed.

❓ Frequently asked

The crown fell out after two months

That is a failed treatment; the dentist redoes it at no charge in most countries within a guarantee period of a year or more.

The bill was three times the estimate

Work beyond the estimate needs your consent unless urgent; dispute the excess and ask CNS — Caisse nationale de santé to check.

Can I switch dentist mid-treatment?

Yes. Ask for the records and X-rays to be sent to the new practice; they cannot refuse.
