What is a dental crown?

As we get older, many of us discover that our teeth that are no longer as structurally sound as they were in our youth. Our Lismore dentist in Cumulus dental Lismore will usually be able to recognize problem areas which may lead to tooth damage and a need for dental crowns.

Grinding your teeth, an improper bite, age, fillings and tooth decay are all contributing factors in the erosion, cracking or breakage of your teeth.

Dental crowns are also capable of replacing missing teeth entirely. The dental crown is secured to the teeth on either side using a bridge section which connects the two dental crowns. Alternatively, single tooth dental implants can be placed. This eliminates the need for supporting the dental crowns so no bridge is required.

So, we may recommend the placement of a dental crown for a wide range of problems but, in general, the majority of these reasons usually fall within one of the following basic categories:

  • The restoration of a tooth to its original shape.
  • The strengthening of a weak tooth.
  • To improve the esthetic appearance of a tooth.

Dental Bridges

A dental bridge is one method to fill a gap created by a missing tooth (or teeth). Dental bridge is a custom-made false tooth or teeth, that is permanently placed between two healthy teeth, filling in the area left by a missing tooth or teeth. The bridge is held in place by crowns placed on the healthy teeth on each side of space to be filled.

Benefits of Dental Bridges

  • Restores your smile
  • Restores your ability to properly chew and speak
  • Maintains the shape of your face
  • Distributes the forces in your bite properly by replacing missing teeth
  • Prevents remaining teeth from drifting out of position
  • Helps preserve the natural function and position of the teeth
  • Restores and maintains natural bite

Types of Dental Bridges

1. Traditional bridges

Traditional bridges involve creating a crown for the tooth or implant on either side of the missing tooth, with a bridge in between. Traditional bridges are the most common type of bridge.


  • not removable
  • great looks (aesthetics)
  • protective
  • long lasting
  • relatively quick
  • less invasive than implants



2. Cantilever bridges

Cantilever bridges are usually used when there are adjacent teeth on only one side of the missing tooth or teeth.



3. Maryland bridges

Marlyland bridges also called a resin-bonded bridges or a Maryland bonded bridges. Maryland bridges supported by a metal framework. Metal wings on each side of the bridge are bonded to the back of existing teeth.

Advantages of Maryland bridge:

  • no/slight preparation of adjacent teeth is required,
  • relatively quick
  • eliminates the need of surgical procedures
