Dental Crown Treatments

Crowns are an ideal way to rebuild teeth that have been broken, or weakened by decay or by a large filling. 

The crown fits over the remaining part of the tooth, making it strong and giving it the shape and contoured appearance of a natural tooth.

Here are some of the most frequently asked questions from clients of Shields Dental & Implant Clinic Limerick, in relation to crowns.

There are a number of reasons, including:

  • Weakening of the tooth by a large filling
  • You may want to improve the appearance of a tooth that is marred by discoloured fillings.
  • To protect a root filling
  • To repair a tooth damaged in an accident
  • To help hold a bridge or denture firmly in place
Most crowns are made from porcelain bonded with non-precious metal. The metal base is made, and layers of porcelain are applied over it. There are alternatives, and new materials are frequently introduced to the production of crowns. Here are some of the options currently available at Shields Dental & Implant Clinic:

  • Porcelain: these are not as strong as bonded crowns but look very natural. They are used most often for front teeth.
  • Porcelain & Composite: crowns made from porcelain and composite resin materials often look the most natural. However, these crowns are not as strong as the bonded metal crown
  • Precious Metal (gold and palladium): these crowns are very strong and hard-wearing. They are usually used at the back of the mouth, where they will not be highly visible.
The dentist prepares the tooth to the ideal shape, removing most of the outer surface to leave a strong inner ‘core’. The amount of tooth removed will be the same as the thickness of the crown to be fitted. Once the tooth is shaped, the dentist takes one impression of the prepared tooth; another impression, of the opposite jaw; and possibly a third to indicate your bite.
A dental technician, skilled in making crowns, takes from the dentist the impressions and any other information about your teeth, including shade, and makes a model of your mouth, on which the crown will be made to ensure a perfect fit.
