Frequently asked questions
about dental prostheses

How is a crown mounted?

If the restoration has been “tried on” and fits perfectly, it is bonded to the tooth using a special cement. The procedures and cements for inlays, onlays and partial crowns can vary from the procedure for crowns, bridges and implant supported restorations.

How long does it take to get a crown?

Normally two appointments are enough to fit a crown. In the first appointment the tooth is prepared and an impression is taken. Based on the impression the dental technician makes the crown in the desired material. In the meantime the tooth is protected by a plastic temporary crown. During the second appointment the actual crown is fitted and cemented to the tooth by a strong layer of adhesive cement.

Inlay or partial crown?

The choice of inlay or partial crown to repair a cavity of a tooth depends on how big the damage to the tooth is. Inlays are generally used for small defects, and partial crowns for larger defects.

What should I do if the inlay falls out?

In the unlikely event that the inlay does fall out, come to our clinic straight away. The hole in the tooth must be resealed as quickly as possible, so that bacteria and germs cannot penetrate and lead to caries or an inflammation.

Which material is best for an inlay or onlay?

Ceramic inlays and onlays offer perfect aesthetics and high durability. The material is characterised by its colour fastness and high biological compatibility.

Changes in temperature are not transmitted through to the interior of the tooth and therefore don’t affect taste. Gold inlays and onlays are only necessary for patients who grind or press their teeth strongly.

How many teeth can you put on a bridge?

Up to three teeth at the side of the mouth or four teeth at the front can be replaced by a bridge. It is preferable to treat larger tooth gaps with implant supported dental restorations.

How long does a dental bridge last?

Bridges have very good durability with an average lifetime of 20 years. But this depends very much on oral hygiene. Bridges must be well looked after just like natural teeth.

A crown or bridge can be irreparably damaged as a result of tooth decay at the edge of the restoration. Brushing daily with a fluoride toothpaste and using dental floss and or interdental brushes once a day extends their lifespan. Regular visits to the dentist for professional cleaning and check-ups also contribute significantly to a longer lifespan.

What is an adhesive bridge?

An adhesive or Maryland bridge is a fixed bridge consisting of a metal or ceramic framework which is bonded to the neighbouring teeth. Single tooth gaps are usually fitted with adhesive bridges if implants cannot or should not be used. Younger patients who cannot be fitted with implants because their jaw is still growing especially benefit from this option.

Are adhesive bridges suitable for teeth at the back of the mouth?

Yes, adhesive bridges can find application in the posterior region. However, only a single missing tooth can be replaced here. Having said this, the adhesive bridge is not suitable for free-end gaps, as in the back of the mouth they must be bonded to two supporting teeth. In the case of a free-end gap, an implant is the best option.

What happens if the adhesive bridge becomes loose?

If one of the wings becomes loose, you should come to our practice straight away. If the bridge is undamaged, in most cases we can re-bond it easily. However, re-cemented adhesive bridges have a slightly shorter lifespan than new adhesive bridges.

What does implant prosthetics mean?

Implant prosthetics or prosthodontics refers to tooth replacements which are mounted on implants. This has many advantages:

  • Neighbouring teeth are protected, since they do not need to be ground down to be used as supporting teeth.
  • The artificial tooth root ensures that the jaw bone will not recede any further.
  • The implant supported tooth replacement is barely distinguishable from a real tooth.

Can every dental prosthesis be fixed on implants?

Generally, yes. Single tooth gaps are fitted with an implant, to which a crown is fixed. Larger gaps can be closed again thanks to implant supported bridges or partial prostheses. Even in cases of total tooth loss, we can fix the third teeth safely and firmly in the mouth. Ill-fitting, abrasive dentures are now a thing of the past.
