Crowns / Bridges

Crowns

crowns-1Although teeth are strong and difficult to break, trauma can chip or break them. Teeth can also become severely weakened by tooth decay and root canal treatment. In these cases, a crown is often the best way to save a tooth and strengthen it. A crown fits over the existing natural tooth and replaces the natural crown, the part of the tooth seen above the gums. 

 

Bridges

Bridges replace one or more missing teeth. They consist of an artificial tooth anchored to the natural teeth on each side of the gap. If a tooth is lost through an accident, or is too badly decayed to save with a crown, a bridge may be the treatment of choice.

bridgeCrowns and bridges are usually made of porcelain and gold alloy. Porcelain is strong and can be made to match the appearance and colour of the natural teeth.

Teeth have many functions apart from chewing and biting, so missing teeth should be replaced for the following reasons:

  • To improve appearance
  • To prevent stresses causing damage to other teeth
  • To prevent the teeth near the gap from shifting
  • To maintain the natural bite
  • To improve chewing ability

You will require at least two appointments for preparation and fitting of a crown or bridge. Sometimes a tooth will need a root canal filling and perhaps a post, before crown or bridge treatment.

Preparation for Crowns and Bridges

After the area is numbed with a local anaesthetic, the tooth or teeth are shaped and then an accurate impression is taken to record changes to the prepared tooth. The impressions are sent to a dental technician who makes the crown or bridge according to specifications set by the dentist.

At the next appointment, the temporary crown or bridge is removed and the new crown or bridge is placed and cemented after first checking that shape and colour match properly.

After fitting, the crown should feel comfortable and natural in your mouth.

Hygiene and Care

Crowns and bridges should last for many years. However, there is no lifetime guarantee. As with natural teeth, it depends on good dental hygiene and oral health. Therefore, regular dental check-ups are advisable.

Possible Side Effects of Crown or Bridge Treatment

Please note: all invasive or surgical procedures carry risk. Please discuss the benefits and risks of procedures with your dentist before proceeding wth treatment. Your dentist will be happy to discuss any of these issues with you.
