 Crowns

 

What are they?

  • The crown is the visible part of the tooth. An artificial crown covers a weak tooth above the gum line and protects it. They are made up of metal or porcelain, or just porcelain with metal bits mixed in to increase the strength.

What will my dentist do?

  • The dentist will shape and form the artificial tooth to replicate the characteristics of a normal tooth.
  • Preparation time will depend on the damage of the tooth and whether or not it will be need a build up of filling.
  • 'Removing the nerve' may have to take place if the tooth needs to be root-filled first. Often the crown is held by a peg in the root canal, that is if a lot of tooth is missing.
  • The dentist will use soft, mouldable material to make exact 'impressions' of the tooth that has to be crowned and also of the nearby teeth. This is then passed onto a dental technician that uses the impression to make the crown the exact size needed.
  • The use of a thin cord would be used to hold the gum away from the tooth for a more accurate impression around the edges.
  • A temporary crown would be put over the tooth until the permanent crown has been made. The temporary can cope with chewing but not as strong as the permanent.
  • Your dentist will make small adjustments once your crown is fitted to make sure that you can bite comfortably. The crown is tried on first then glued into place.

What are the benefits?

  • Crowns are very strong and look exactly like natural teeth in which the colour and shape can be assigned to match current teeth.
  • If the tooth is strong underneath the crown, the crown can last for many years if you look after your teeth and mouth.
  • Crowns can also improve the appearance of misshapen or discoloured teeth.
