1. What is a replacement crown?

  • A replacement crown replaces part or all of the natural crown of a tooth. It is also called a crown or a cap.
  • The visible part of the tooth is called the crown. It is joined to the root of the tooth which is in the jawbone under the gum.
  • When all, or a large part of the original crown of a tooth has been destroyed, a replacement crown is made to restore the tooth.
  • A replacement crown is also made for a healthy tooth when it forms part of a bridge, or when it is used for cosmetic purposes.
  • A natural crown that has become discoloured or unsightly can be replaced with a new crown. The new crown can be made to match the surrounding teeth in colour, shape and proportion.
  • A replacement crown is prepared by the dentist and made by a dental technician.

2. How is a replacement crown prepared and made?

  • The dentist will pare down the tooth, and remove any decay.
  • An impression of the prepared tooth is taken using an elastic material. This is sent to the dental technician, where the replacement crown is made.
  • A temporary acrylic crown will be fitted over the prepared tooth, while the replacement crown is being made.
  • The new crown is then cemented onto the prepared tooth.
  • Replacement crowns can also be used as supports for a bridge, where they are joined to artificial teeth to fill a gap between the teeth.

3. What are replacement crowns made of?

  • Replacement crowns may be made of porcelain, gold or a combination of metals.
  • Porcelain can be fused to a metal base when the crown needs added strength, and when a good appearance is required. This is called a porcelain bonded crown.
  • Temporary crowns are made of acrylic.

4. Will the pared down tooth be sensitive until I receive my crown?

  • No, it won’t. The dentist will make and install a temporary acrylic crown to protect the pared down tooth. It will look good and be comfortable to eat with.

5. Is it uncomfortable or painful to have a crown made?

  • The procedure is not painful because a local anaesthetic is used during the preparation of the tooth, and the taking of the impression.
  • Pain relief is seldom necessary after the treatment.
  • Sensitivity to hot and cold sometimes occurs after the crown has been cemented, but this is usually temporary.

9. What role does the dental technician play?

  • The dental technician plays an important part in the making of a crown. It takes skill and experience to fabricate a crown from the impression that the dentist provides. The crown must be very precise in its colour and dimensions.
  • The impression that is received from the dentist is used to make a plaster or stone cast of the prepared tooth or teeth. The cast is a copy of the tooth or teeth.
  • It allows the technician to make a crown over the exact copy of a prepared tooth.
  • The technician will use the same shade/colour guide as the dentist, to ensure that the replacement crown will match the colour of the adjacent teeth.
