Crowns & Bridges FAQs

Why would I need a crown ?

A root canal treated, worn, grossly decayed, severely sensitive tooth may require a crown to protect, strengthen and prevent further damage so the teeth can function efficiently.

Will it not weaken my tooth if I have a cap?

No. On the contrary it will make the existing tooth stronger.

What if my tooth is severely damaged ?

We’ll use materials to strengthen the tooth and then reduce the size and use special adhesive materials to cement the cap to the tooth.

What if my cap breaks ?

We can re-cement it or repair it.

What is a bridge ?

A bridge has many crowns as one unit. It is used even in case of missing teeth. The tooth that is replaced is supported by the adjacent crowns acting like pillars.

How long does it take ?

It takes about two visits to get the crown or bridge cemented in place.

What are Dental Crowns and Tooth Bridges?

Both crowns and most bridges are fixed prosthetic devices. Unlike removable devices such as dentures, which you can take out and clean daily, crowns and bridges are cemented onto existing teeth or implants, and can only be removed by a dentist.

How do Crowns Work ?

A crown is used to entirely cover or “cap” a damaged tooth. Besides strengthening a damaged tooth, a crown can be used to improve its appearance, shape or alignment. A crown can also be placed on top of an implant to provide a tooth-like shape and structure for function. Porcelain or ceramic crowns can be matched to the color of your natural teeth. Other materials include gold and metal alloys, acrylic and ceramic. These alloys are generally stronger than porcelain and may be recommended for back teeth. Porcelain bonded to a metal shell is often used because it is both strong and attractive.
Your dentist may recommend a crown to:
Replace a large filling when there isn’t enough tooth remaining
Protect a weak tooth from fracturing
Restore a fractured tooth
Attach a bridge
Cover a dental implant
Cover a discolored or poorly shaped tooth
Cover a tooth that has had root canal treatment

How do Bridges Work ?

A bridge may be recommended if you’re missing one or more teeth. Gaps left by missing teeth eventually cause the remaining teeth to rotate or shift into the empty spaces, resulting in a bad bite. The imbalance caused by missing teeth can also lead to gum disease and temporomandibular joint (TMJ) disorders.
Bridges are commonly used to replace one or more missing teeth. They span the space where the teeth are missing. Bridges are cemented to the natural teeth or implants surrounding the empty space. These teeth, called abutments, serve as anchors for the bridge. A replacement tooth, called a pontic, is attached to the crowns that cover the abutments. As with crowns, you have a choice of materials for bridges. Your dentist can help you decide which to use, based on the location of the missing tooth (or teeth), its function, aesthetic considerations and cost. Porcelain or ceramic bridges can be matched to the color of your natural teeth.

How are Crowns and Bridges Made ?

Before either a crown or a bridge can be made, the tooth (or teeth) must be reduced in size so that the crown or bridge will fit over it properly. After reducing the tooth/teeth, your dentist will take an impression to provide an exact 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 teeth.
Using this impression, a dental lab then makes your crown or bridge, in the material your dentist specifies. A temporary crown or bridge will be put in place to cover the prepared tooth while the permanent crown or bridge is being made. When the permanent crown or bridge is ready, the temporary crown or bridge is removed, and the new crown or bridge is cemented over your prepared tooth or teeth.
