Bridging the Gap with a Dental Bridge

One or more missing teeth can adversely affect the appearance and functionality of your smile. Missing teeth can cause a change in occlusion (bite), shifting of the teeth, temporomandibular joint disorder (TMJ), speech impediments, an increased risk for periodontal disease and a greater chance of tooth decay.

Dental bridges, like implants and partial dentures, are used to replace missing teeth. There are several types of fixed dental bridges (cannot be removed), including conventional fixed bridges, cantilever bridges and resin-bonded bridges.

Typically, conventional and cantilever bridges require shaping of the teeth surrounding a missing tooth. Crowns are then placed on the shaped teeth and attached to an artificial tooth (called a pontic).

A resin-bonded bridge requires less preparation of adjacent teeth. It is often used to replace front teeth, provided that the gums are healthy and the surrounding teeth do not have extensive dental fillings.

The Dental Bridge Procedure

During the first visit, your dentist examines the health of your gums and other teeth to evaluate if you are a candidate for a dental bridge. If you are a candidate for a dental bridge, you are given a local anesthetic so your dentist can prepare the teeth required to support the bridge. If the support teeth are decayed or badly broken down, your dentist may have to build them back up before they can be used as support teeth for a bridge.

Next, your dentist takes an impression of the prepared teeth with a putty-like material that is used to create a model of your teeth. Your bridge is fabricated based on this model by a skilled lab technician so that it precisely fits the prepared teeth. It is important that your restoration fit perfectly to avoid additional oral health problems such as tooth decay.

While your bridge is being fabricated, your dentist fits you with a temporary bridge so the teeth and gums can be protected from damage until your permanent bridge is ready.

To complete the dental bridge procedure, you must return to the dental office for a second visit to have the bridge fitted and cemented.

The Cost of Dental Bridges

The cost of dental bridges depends on several factors, including:

• The potential need for additional procedures (such as fillings or root canals) in one or two of the adjoining teeth.
• The artistic technique of the dentist and lab technician.
• The location of the dentist.
• The coverage provided by your dental insurance.
• The type of material used in the bridge.
• The preparation of teeth involved in the bridge procedure.
