A dental bridge uses false teeth to permanently fill gaps left by missing teeth. Bridges offer an alternative to removable dentures. Gaps can cause the bite to change over time, affecting the overall facial structure as well. Besides cosmetic reasons, dental bridges can also improve speech, chewing, and comfort. They are attached to the teeth on each side of the open space. Dental practitioners use either tooth-colored porcelain or metal material for 
bridges.

There are different types of dental bridges.

The traditional fixed bridge incorporates a dentalcrown on either side of the bridge.
The Maryland dental bridge or resin-bonded bridge fills in the front teeth.

Porcelain or metal bridges are used and attached to the back of the teeth that sit beside the gap. This method is the fastest technique, requiring only one procedure. For the implant-supported bridge, patients first need a dental implant. Dentists insert the implants into the jawbone before placing the bridge in a second procedure. The implant surgery involves incisions that take time to heal; therefore, the bridge procedure must be done a few months later. The cantilever bridge is the least common method only used when one side of the gap has a natural tooth.

Before beginning the procedure, patients must undergo a clinical examination. Dentists look for any tooth decay and gum disease that requires treatment before placing the dental bridge. X-rays also help provide an accurate measurement of the teeth and mouth. After numbing, the dentist carefully files down the teeth beside the gap and takes a mold for a customized dental bridge. Once the bridge is made, it is permanently attached to the  existing teeth. It is supported down with dental cement or attached with dental implants.

Dental bridges can last anywhere from 5-7 years, but this depends on the patient's dental care and hygiene. Patients should floss and brush their bridges as usual with fluoride toothpaste. There are some risks that come with bridges especially if the bridges are not fitted well. Tooth structure may be weakened since adjacent teeth support the bite force of the missing tooth, too. However, most dental bridges last for many years.
