Crowns and Bridges: Two Sides to the Same Coin

Mar 18, 2017

Restorative dentistry is critical when it comes to replacing teeth that have been lost. The spaces left can cause a variety of problems that can ultimately affect your oral health and by default cause problems with your general health. It may not seem that crowns and bridges could have that big of an impact on your health, but they can.

The Differences between Crowns and Bridges

Both of these dental prosthetics involve crown work; however, a crown does not replace a missing tooth. Bridges, on the other hand, do fill in the space between teeth when one or more teeth are missing. The artificial teeth replacements on a bridge are called pontics. The pontics are affixed to crowns that are cemented to the abutment teeth or teeth on either side of the space.

Benefits of Dental Bridges

When a tooth is missing, the space it leaves becomes a breeding ground for a cascade of dental issues. The teeth adjacent may begin to shift into the space, causing the gradual development of small spaces between teeth. These teeth may also begin to lean into the space or twist out of alignment, throwing off your bite or occlusion. In addition, particularly where the loss of molars is concerned, the valuable chewing surface is missing. This surface area is needed in order for you to properly break down food particles so that the most nutrition can be extracted. It is also important for the optimal digestion of food.

Crowns and the pontics that fill in the gaps restore not only a healthy mouth, they also restore your smile. They are made to look like your natural teeth, usually out of porcelain fused to metal or a ceramic resin.


When a tooth has had root canal therapy the nerve has been removed so the tooth is no longer living. Such teeth often become brittle and are more vulnerable to breakage. Protecting a tooth-like this with dental crown adds stability and strength. Usually, the crown is made from a material that is tooth-colored, so the crowned tooth looks completely natural. A tooth with a very large filling is also a good candidate for a dental crown.

Similarities of Crowns and Bridges

In both cases, the tooth or teeth accepting the crown needs to be prepared. In the case of bridgework, both teeth on either side of the area to be bridged need to be prepared for crowns. Preparation involves shaping the tooth so that a crown will fit over it. An impression of the tooth is taken and a mold is created so the crown can be fashioned over the mold. In some instances, this is accomplished by way of a computer. Once the crown has been made it is fitted on the tooth and trimmed so that the bite is comfortable. When sufficiently trimmed, the new crown is cemented in place. When a bridge is being placed, both crowns are fitted simultaneously.
