A dental bridge is a common and effective solution for replacing one or more missing teeth. It literally bridges the gap created by missing teeth, restoring both the function and appearance of your smile. Let’s break down what a dental bridge is, the types available, and what you can expect from the procedure.
A dental bridge consists of two or more crowns for the teeth on either side of the gap—these anchoring teeth are called abutment teeth—and a false tooth or teeth in between. Dental bridges are supported by natural teeth or implants.
Types of Dental Bridges
There are four main types of dental bridges:
-
- Traditional Dental Bridges: The most common type, traditional bridges involve creating a crown for the tooth or implant on either side of the missing tooth, with a pontic in between. They are usually made of porcelain fused to metal or ceramics.
- Cantilever Dental Bridges: These are used when there are adjacent teeth on only one side of the missing tooth or teeth. Cantilever bridges aren’t very common and are not recommended in the back of the mouth where they can put too much force on other teeth and damage them.
- Maryland Dental Bridges: Also known as a resin-bonded bridge, Maryland bridges are made of porcelain fused to metal or ceramic teeth and gums, supported by a metal or porcelain framework. This type of bridge is bonded to your existing teeth, which means it requires less alteration to your surrounding teeth
- Implant-Supported Dental Bridges: As the name suggests, these bridges are supported by dental implants. Typically, one implant is surgically placed for every missing tooth, and these implants hold the bridge in position. Implant-supported bridges are considered very strong and stable.
The Procedure
Getting a dental bridge typically involves several steps and multiple visits to your dentist:
- Initial Consultation: Your dentist will examine your teeth and gums, take X-rays, and determine the best type of bridge for your situation.
- Preparation of Abutment Teeth: In the case of traditional or cantilever bridges, the abutment teeth are prepared by removing a portion of enamel to allow room for a crown to be placed over them.
- Impressions: Impressions of your teeth are taken, which serve as a model from which the bridge, pontic, and crowns will be made. You’ll receive a temporary bridge to wear to protect the exposed teeth and gums while your bridge is being made.
- Placement of the Permanent Bridge: At your next visit, your temporary bridge will be removed, and your new, permanent bridge will be checked and adjusted to achieve a proper fit. Multiple visits may be required to check the fit of the metal framework and bite. If it’s a fixed bridge, your dentist may temporarily cement it in place for a couple of weeks to make sure it fits properly. After a couple of weeks, the bridge is permanently cemented into place.
Benefits of a Dental Bridge
A dental bridge can:
-
- Restore your smile.
-
- Restore the 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.
Taking Care of Your Dental Bridge
With proper care, a dental bridge can last many years. It’s important to:
-
- Brush and floss daily to prevent cavities and gum disease that can lead to tooth loss.
-
- Use a special floss threader to clean under the pontic.
-
- Visit your dentist regularly for checkups and professional cleanings.
Conclusion
A dental bridge is a tried-and-true solution for missing teeth, providing both functional and aesthetic benefits. If you’re missing a tooth or teeth and considering your options, talk to your dentist about whether a dental bridge is right for you.
