Dental Health: Bridges

Dental bridges literally bridge the gap created by one or more missing teeth.

A bridge is made up of two crowns for the teeth on either side of the gap -- these two anchoring teeth are called abutment teeth -- and a false tooth/teeth in between. These false teeth are called pontics and can be made from gold, alloys, porcelain or a combination of these materials. Dental bridges are supported by natural teeth or implants.

What Are the Benefits of Dental Bridges?

Bridges:

  • Restore your smile
  • Restore your ability to properly chew and speak
  • Maintain the shape of your face
  • Distribute the forces in your bite properly by replacing missing teeth
  • Prevent remaining teeth from drifting out of position

What Types of Dental Bridges Are Available?

There are three main types of bridges:

  • Traditional bridges involve creating a crown for the tooth or implant on either side of the missing tooth, with a pontic in between. Traditional bridges are the most common type of bridge and are made of either porcelain fused to metal or ceramics.
  • Cantilever bridges are used when there are adjacent teeth on only one side of the missing tooth or teeth.
  • Maryland bonded bridges (also called a resin-bonded bridge or a Maryland bridge) are made of plastic teeth and gums supported by a metal framework. Metal wings on each side of the bridge are bonded to your existing teeth.

What Is the Process for Obtaining a Dental Bridge?

During the first visit, the abutment teeth are prepared. Preparation involves recontouring these teeth by removing a portion of enamel to allow room for a crown to be placed over them. Next, impressions of your teeth are made, which serve as a model from which the bridge, pontic, and crowns will be made by a dental laboratory. Your dentist will make a temporary bridge for you to wear to protect the exposed teeth and gums while your bridge is being made.

During the second visit, your temporary bridge will be removed and the new permanent bridge will be checked and adjusted, as necessary, to achieve a proper fit. Multiple visits may be required to check the fit of the metal framework and bite. This is dependent on each individual's case. If the dental bridge is a fixed (permanent) bridge, your dentist may temporarily cement it in place for a couple of weeks to make sure it is fitting properly. After a couple weeks, the bridge is permanently cemented into place.

Gingivitis Introduction

Gingivitis, also generally called gum disease or periodontal disease, describes the events that begin with bacterial growth in your mouth and may end - if not properly treated - with tooth loss due to destruction of the tissue that surrounds your teeth.

Actually, gingivitis and periodontitis are two distinct stages of gum disease.

What's the Difference Between Gingivitis and Periodontitis?
 

Gingivitis usually precedes periodontitis. However, it is important to know that not all gingivitis progresses to periodontitis.

In the early stage of gingivitis, bacteria in plaque build up, causing the gums to become inflamed (red and swollen) and often easily bleed during tooth brushing. Although the gums may be irritated, the teeth are still firmly planted in their sockets. No irreversible bone or other tissue damage has occurred at this stage.

When gingivitis is left untreated, i...
