What is Crown and Bridge?

Crowns and bridges are both fixed prostheses. Unlike removable dentures, such as dentures that you can remove and clean daily, crowns and bridges are bonded over existing teeth or implants and can only be removed by the dentist.


What is the Function of Crowns?

The crown is used to completely cover the damaged tooth. Besides strengthening the damaged tooth, the crown can also be used to correct the appearance, shape or alignment. The crown can also be placed over the implant to provide a tooth-like shape and structure for it to function. Porcelain or ceramic crowns can be produced in the natural color of your tooth. Other materials that can be used; gold and metal alloys, acrylic or ceramic. These alloys are generally stronger than porcelain and are recommended for posterior teeth. Porcelain with metal infrastructure can be used because it is strong and attractive.


Your dentist may recommend crowns for the following reasons:


  • When there is not enough tooth volume to fill, replace the filling.
  • To prevent weakened teeth from cracking
  • To repair a broken tooth
  • To make a bridge
  • To cover a dental implant
  • To cover a yellowed or misshapen tooth
  • To cover a root canal treated tooth

Why Is a Bridge Made?

A bridge may be recommended if you have one or more missing teeth. The cavities caused by the missing tooth can cause the teeth to slip into the spaces or the tooth to rotate in place and change the mouth closure. Imbalance caused by missing teeth can also lead to gum disease and temporomandibular joint (TMJ)may cause malfunctions.

Bridges are used to replace one or more missing teeth. They fill the non-dental space. Bridges are attached to natural teeth or implants surrounding the empty space. These teeth, called supports, act as stabilizers for the bridge. This new tooth, which will fill the gap, is attached to the support crowns. As with crowns, you can choose from many materials within the bridge. Your dentist can assist you in deciding which material to use based on the location of the missing tooth (or teeth), function, aesthetic expectations and cost. Porcelain or ceramic bridges can be produced in the natural color of your tooth.


How are Crowns and Bridges Made?

Before a crown or bridge is made, the abutment tooth (or teeth) is reduced to fit the crown. After reducing the tooth(s), your dentist will model your tooth to make an accurate mold for the crown or bridge. If porcelain is to be used, your dentist will determine the correct shade for the crown or bridge to match the color of your existing tooth.

Using this mold, the dental laboratory prepares the crown or bridge from the material specified by your dentist. Until the permanent crown or bridge is made, the temporary crown or bridge is placed in place to cover the prepared tooth. When the permanent crown or bridge is ready, the temporary crown or bridge is removed and the new crown or bridge is bonded over the prepared tooth or teeth.

How Long Can a Crown and Bridge Be Used?

Crowns and bridges can be used for life, but they can sometimes come loose and fall off. The most important thing you need to do for a crown or bridge to be long-lasting is to protect your oral health. Maintain the health of your teeth and gums by brushing your teeth twice a day with fluoride toothpaste and flossing daily. Also, go to your dentist regularly for dental exams and professional cleanings.

To avoid damage to the new crown or bridge, do not try to chew hard food, ice, or other hard objects.
