Dental prostheses

Types of prostheses

There are two types of dental prosthesis:

  • Removable dentures (partial or full)
  • Fixed dentures

Removable dental protheses

Removable dental prostheses

The choice of a removable prosthesis depends on the number of teeth to be replaced and the materials used:

  • Partial dentures are held in place by clasps or attachments.
  • Full dentures work on the principle of the juxtaposition of two identical surfaces: the saliva between the gum and the plaque creates an "adhesive suction".

Fixed dental prostheses (crowns, bridges, ...)

Fixed prosthesis

There are different types of fixed prosthesis:

  • Crown: This reinforces a "filled" tooth that is no longer strong enough. A crown can also be used to anchor a bridge designed to replace one or more teeth.
  • Bridge: This is made up of crowned abutment teeth and elements that replace missing teeth.
  • Pivot tooth: It completely replaces the visible part of the tooth and is fixed in the root.

Conditions for coverage

Estimate and authorisation


Some procedures are labelled DSD (dépassement sur devis, which means surcharges on estimate), allowing dentists to exceed the official tariffs, but only if they have presented you with a detailed estimate and with your agreement. Dentists are free to determine the fees for these procedures "with tact and moderation".


In addition to DSD, some dental prosthesis services are labelled ACM (autorisation du contrôle médical). In this case, the prior estimate must be sent to the CNS, as it requires the authorisation of the Medical Board of Social Security (CMSS). Usually, your dentist in Luxembourg will send the estimate to the CNS, or will ask you to send it.

First, the CNS carries out administrative checks, then submits the request to the CMSS for medical assessment. If the CMSS gives a favourable opinion, the CNS will send you an authorisation on the estimate itself. This authorisation specifies the exact amount that the CNS will reimburse.

At the end of the treatment, you send the CNS the paid and receipted invoice with the authorisation on the estimate to request reimbursement.

Right to a new dental prosthesis

Fixed dentures

These dentures are renewed every 12 years.

Removable dentures

These dentures are renewed every 5 years.

However, the Medical Board of Social Security (CMSS) may reduce the renewal period in the following cases:

  • maxillofacial bone fracture;
  • neoplasia affecting the maxillo-buccal region;
  • very high-dose biphosphonate treatment;
  • dental prosthetic treatment before the age of 17.


Temporary dental prostheses

These prostheses are only covered if they are declared functionally essential by the Medical Board of Social Security (CMSS) and if the masticatory coefficient is less than fifty per cent.


Relining is the reshaping of the resin plate or skeleton to adapt the prosthesis to the mouth.

The total (DA75) or partial (DA74) relining of a removable denture is covered once per denture and per calendar year starting with the second relining.

The full list of dental services covered is set out in the dentists' nomenclature. Click here to access the dental nomenclature (list in PDF format).


Payment method

Payment method

As a general rule, you pay the invoice and request reimbursement from the CNS.

You send the CNS the original of the paid and receipted invoice showing your 13-digit national identification number.

If this is your first request for reimbursement, please enclose a bank identity statement (relevé d'identité bancaire RIB).

Sending mail to the CNS (L-2980 Luxembourg) from within Luxembourg is postage free.

Reimbursement rate

Reimbursement rate

Generally speaking, dental prostheses are covered at 80% of the official rates.

You do not have to pay the 20% personal contribution:

  • If you can prove that you have consulted a dentist annually as a preventive measure during the 2 calendar years preceding the delivery of the prosthesis.
  • For children under the age of 18.
  • For the renewal or repair of a total prosthesis.
  • For restorative maxillofacial prostheses.
Personal conveniences

Personal convenience

In certain situations, dentists may charge an additional fee for personal convenience (CP), provided they have informed you in advance and received your agreement. These surcharges are not reimbursed by the CNS and are entirely at your expense.

For more information on personal conveniences, please consult our "Personal conveniences" page.

Do you have any questions about dental treatments and reimbursements? Talk to your dentist! As each dental treatment is unique, your dentist will assess the treatments they consider necessary on a case-by-case basis. The CNS cannot give you any medical advice.
