What Is a Dental Bridge?
A dental bridge is a fixed restoration that fills the space left by one or more missing teeth. It works by attaching a false tooth, called a pontic, to crowns placed on the natural teeth next to the gap. These supporting teeth are called abutments.
Unlike dentures, a dental bridge is permanently cemented in place. You do not remove it for cleaning. Once placed, it restores your ability to chew, speak clearly, and maintain the alignment of your remaining teeth. Without a replacement, the teeth next to a gap can shift over time, leading to bite problems and additional tooth loss.
Types of Dental Bridges
There are four main types of dental bridges. The right choice depends on where the missing tooth is located, the condition of the surrounding teeth, and your overall oral health.
Traditional Bridge
A traditional bridge is the most common type. It uses crowns on the teeth on both sides of the gap to hold the pontic in place. This type works best when you have strong, healthy teeth on both sides of the missing tooth.
The main drawback is that the abutment teeth must be filed down to fit the crowns. This removes healthy tooth structure that cannot be replaced.
Cantilever Bridge
A cantilever bridge attaches to a crown on only one side of the gap. This option is used when there is only one natural tooth next to the missing tooth, such as at the back of the mouth.
Because it is supported on one side only, a cantilever bridge puts more stress on the abutment tooth. It is generally recommended only for areas with lower biting force.
Maryland Bridge (Resin-Bonded Bridge)
A Maryland bridge uses a metal or porcelain framework bonded to the backs of the teeth next to the gap. Unlike a traditional bridge, it does not require crowns on the abutment teeth, so less natural tooth structure is removed.
Maryland bridges work best for front teeth where biting forces are lower. They may not be strong enough for molars and can sometimes debond over time.
Implant-Supported Bridge
An implant-supported bridge uses dental implants as anchors instead of natural teeth. Implants are titanium posts surgically placed into the jawbone. This type is often used when multiple teeth are missing in a row.
Because implants integrate with the bone, this type of bridge tends to be the most stable and long-lasting option. It also preserves the surrounding natural teeth since they do not need to be modified. The trade-off is a longer treatment timeline and higher cost.
The Dental Bridge Procedure: Step by Step
The dental bridge procedure typically takes two to three appointments spread over two to four weeks. Here is what happens at each stage.
First Appointment: Tooth Preparation
Your dentist or prosthodontist numbs the area around the abutment teeth. They then reshape these teeth by removing a layer of enamel to make room for the crowns that will support the bridge. The amount removed depends on the type of bridge and crown material being used.
After preparing the teeth, your provider takes an impression or digital scan of the area. This model is sent to a dental laboratory where the bridge is custom-made to match your bite and the color of your natural teeth. Before you leave, a temporary bridge is placed over the prepared teeth to protect them.
Laboratory Fabrication
The dental lab uses the impressions to build your permanent bridge. This typically takes one to two weeks. Bridge materials include porcelain fused to metal, all-ceramic, or zirconia. Your provider will discuss material options before the first appointment based on the location of the bridge, aesthetics, and durability needs.
Second Appointment: Fitting the Permanent Bridge
At this visit, the temporary bridge is removed and the permanent bridge is placed. Your provider checks the fit, bite alignment, and color match. Minor adjustments are common at this stage.
Once everything fits properly, the bridge is permanently cemented in place. The entire fitting appointment usually takes 30 to 60 minutes.
Recovery and Aftercare
Most patients experience mild sensitivity or soreness for a few days after each appointment. Over-the-counter pain relievers are usually enough to manage any discomfort.
It takes about one to two weeks to fully adjust to the feel of a new bridge. During this time, you may notice slight changes in how you chew or speak. This is normal and typically resolves as you get used to the restoration.
Caring for Your Dental Bridge
A dental bridge requires the same basic care as natural teeth, with a few additions.
- Brush twice daily, paying special attention to where the bridge meets the gum line.
- Use a floss threader, interdental brush, or water flosser to clean under the pontic. Regular floss cannot reach this area.
- Avoid chewing hard foods like ice, hard candy, or popcorn kernels directly on the bridge.
- See your dentist for regular checkups so they can monitor the bridge, abutment teeth, and surrounding gums.
How Long Does a Dental Bridge Last?
With proper care, a dental bridge typically lasts 10 to 15 years. Some bridges last longer, especially implant-supported bridges, which can last 15 years or more. The lifespan depends on the bridge type, the material, your oral hygiene habits, and the health of the supporting teeth or implants.
Dental Bridge Cost and Insurance
The cost of a dental bridge procedure depends on the number of teeth being replaced, the type of bridge, the materials used, and your location.
A three-unit traditional bridge (one pontic and two crowns) typically costs between $2,000 and $5,000. Maryland bridges tend to fall on the lower end of that range. Implant-supported bridges cost more because they include the surgical placement of implants, often ranging from $5,000 to $15,000 depending on the number of implants needed.
Most dental insurance plans classify bridges as a major procedure and cover 50% of the cost after your deductible. Check with your insurance provider for your specific coverage details. Many dental offices also offer payment plans or financing options. Costs vary by location, provider, and case complexity.
When to See a Prosthodontist for a Dental Bridge
General dentists place dental bridges routinely, and for straightforward cases, your regular dentist may be the right choice. However, a prosthodontist is a dental specialist with 3 additional years of training focused specifically on replacing and restoring teeth.
Consider seeing a prosthodontist if you are missing multiple teeth, need an implant-supported bridge, have a complex bite, or want the best possible cosmetic result. Prosthodontists also handle cases where a previous bridge has failed and needs to be replaced.
