Bridges
A dental bridge is a fixed (non-removable) appliance that is an excellent way to replace a missing tooth. Bridges can be used in lieu of an implant with a crown.
Achieving a natural looking smile after a tooth loss is possible with dental bridges. Dental bridges are an alternative method to implants used by dentists to fill a gap created by a missing tooth (or teeth). Depending on the dental bridge type you choose, the procedure and cost will vary.
There are several types of bridges so your dentist will discuss the best options for your particular case. The “traditional bridge” is the most common type and is usually made of porcelain fused to metal. This type of bridge consists of two crowns that go over the two adjacent anchoring teeth to the gap. Attached to the crowns is an artificial tooth or usually made of porcelain that will fill the gap.
Dental bridges are quite durable and will last up to 10 years or longer, however they may need replacement or need to be re-cemented due to normal wear.
Reasons for a fixed bridge:
- Fill space of missing teeth.
- Maintain facial shape.
- Prevent remaining teeth from moving out of position.
- Restoration of chewing and speaking ability.
- Improve your smile.
- Upgrade from a partial denture
The Dental Bridge Procedure
Getting a bridge usually requires two or more visits depending on the type of bridge that will work best for you. For the most common type of bridge, a traditional bridge, the dentist will start by numbing the two anchoring teeth. While the teeth are numb, the two anchoring teeth are prepared by filing down a portion of enamel to accommodate the crowns. Next, the dentist will take impressions of the teeth using a highly accurate impression or mold. The impression will then be sent to a dental laboratory where the bridge will be fabricated. While your permanent bridge is being prepared, a temporary bridge will be made that can be worn for several weeks until your next appointment.
Once the crowns are finished at the laboratory, the false tooth (or teeth) will be bonded to them. At the second visit, your permanent bridge will be carefully checked, adjusted, and cemented to achieve a proper fit. You will receive care instructions at the conclusion of the procedure. Proper brushing, flossing and regular dental visits will aid in the life of your new permanent bridge.
Types of Dental Bridges
There are three types of dental bridges:
Traditional Bridge
This type of dental bridge work consists of two crowns for the teeth on either side of the gap, with a false tooth in between. Traditional bridges are the most commonly used type of dental bridge and are made of ceramic or porcelain fused to metal (PFM). If there are no surrounding teeth to support the crowns, dental implants can be used to fix the bridge in place.
Cantilever Bridge
This type of dental bridge is used when there are teeth on only one side of the gap in the mouth. Two crowns fused to the replacement tooth are used to fix the bridge to the adjacent natural teeth.
Maryland Bonded Bridge
This type of dental bridge is made up of plastic teeth and gums supported by a metal framework. The bonded dental bridge is generally lower in cost than other types of bridges and is the most simple to apply.
