A missing tooth can affect more than the appearance of your smile. The open space may change how you chew, allow neighboring teeth to shift and alter the way biting forces are distributed. A dental bridge replaces the missing tooth or teeth with a fixed restoration designed to restore continuity to your smile.
Dr. Anil Dwivedi will evaluate the teeth surrounding the space, your bite, gum health and available bone before determining whether a bridge is the right option. Depending on your needs, the bridge may be supported by natural teeth or by dental implants.
What Is a Dental Bridge?
A dental bridge is a fixed prosthetic restoration used to replace one or more missing teeth. The replacement tooth, called a pontic, fills the open space and is connected to supporting restorations on either side.
Traditional bridges usually rely on neighboring natural teeth for support. Those teeth are prepared for crowns that hold the replacement tooth securely between them.
Implant-supported bridges use implants instead of natural teeth as anchors. Our dentist will determine which design is appropriate based on the number of missing teeth, the condition of nearby teeth and the supporting bone.
When a Dental Bridge May Be Recommended
A bridge may be considered when one or several neighboring teeth are missing and there is a stable foundation for supporting the restoration.
Our dentist may recommend a dental bridge when:
- One or more teeth are missing in the same area
- Neighboring teeth are strong enough to support a traditional bridge
- You want a fixed alternative to a removable partial denture
- An implant is not preferred or appropriate
- Existing crowns on adjacent teeth may already need replacement
- Restoring the space would improve chewing, speech or smile appearance
The best choice depends on the health of the supporting teeth, the length of the missing-tooth space and the forces placed on that part of the mouth.
How a Traditional Dental Bridge Works
A traditional bridge typically involves preparing the teeth on either side of the gap for dental crowns. These crowned teeth serve as abutments that support the artificial tooth between them.
After the supporting teeth are prepared, a detailed impression or digital scan is created so the bridge can be designed to fit the space, bite and neighboring teeth.
Once the restoration is ready, our dentist evaluates the fit, contacts and bite before bonding or cementing the bridge into place.
Implant-Supported Dental Bridges
When several teeth are missing, implants may sometimes be used to support a bridge without relying on neighboring natural teeth.
An implant-supported bridge can replace multiple teeth while using strategically positioned implants as the foundation. This may reduce the number of implants required compared with replacing every missing tooth individually.
Our dentist will evaluate bone quantity, spacing and restorative needs before deciding whether an implant-supported bridge is appropriate.
Dental Bridge vs. Single-Tooth Implant
When only one tooth is missing, both a traditional bridge and a single-tooth implant may be considered.
A bridge uses neighboring teeth for support, which means those teeth generally need to be prepared for crowns. A single implant replaces the missing tooth independently and does not require reshaping adjacent healthy teeth.
There is no single solution that is right for every patient. Our dentist will compare the condition of the neighboring teeth, available bone, treatment timeline and your preferences before recommending an approach.
Dental Bridges vs. Removable Partial Dentures
A bridge is fixed in place and is not removed for cleaning. A partial denture is removable and may replace several teeth in different parts of the same arch.
A bridge may feel more similar to natural teeth because it remains in place during chewing and speaking. A partial denture may be more appropriate when several teeth are missing in locations that cannot be efficiently restored with one fixed bridge.
Our dentist can explain the advantages and limitations of both options based on your tooth-loss pattern.
Restoring Chewing Function
Missing teeth can make it difficult to chew evenly, particularly when the space involves molars or premolars. Patients may begin favoring one side of the mouth, which can place more stress on the remaining teeth.
Replacing the missing tooth with a bridge can help restore a more complete chewing surface and distribute function across the dental arch.
The bridge still needs to fit the bite carefully, so our dentist will evaluate how the restoration contacts the opposing teeth before treatment is completed.
Preventing Nearby Teeth From Shifting
When a tooth is lost, adjacent teeth may gradually tilt or drift toward the empty space. The opposing tooth can also move farther into the gap because it no longer has normal contact.
These changes can affect bite relationships and may make future tooth replacement more complicated.
A dental bridge fills the missing-tooth space and can help maintain the position of surrounding teeth. If significant movement has already occurred, orthodontic treatment may sometimes be considered before the final restoration is made.
Dental Bridges and Jawbone Changes
A traditional bridge replaces the visible portion of a missing tooth but does not replace the tooth root. Because no root or implant is present in the bone beneath the pontic, the jawbone in that area can continue to change after tooth loss.
Dental implants interact differently with the jaw because they are placed within the bone. This is one reason our dentist may discuss both bridge and implant options when either treatment could work.
The original claim that a traditional bridge itself prevents bone loss should be avoided; its main role is restoring the missing tooth space and function above the gumline.
What Happens During the Dental Bridge Process?
For a traditional bridge, the supporting teeth are numbed and prepared to create room for the restoration. A digital or physical impression is then taken to capture the prepared teeth, surrounding contacts and bite.
An intraoral scanner may be used when appropriate to create a detailed three-dimensional record.
A temporary restoration may be placed while the final bridge is being completed. At the final appointment, our dentist checks the fit and bite before securing the bridge.
Choosing Materials for a Natural Appearance
Dental bridges can be made from different restorative materials depending on where they are located, how much force they need to withstand and how visible they are in the smile.
Tooth-colored materials can be selected to coordinate with surrounding teeth and create a natural appearance. Posterior bridges may require particular attention to strength because they absorb heavier chewing forces.
Our dentist will explain which material is appropriate for the location and design of your bridge.
What If the Supporting Teeth Are Damaged?
The teeth supporting a traditional bridge must have enough healthy structure and periodontal support to function as abutments.
If a supporting tooth has decay, an old filling or structural damage, restorative treatment may need to be completed as part of the bridge process. A tooth with more moderate damage may sometimes be treated with an inlay or onlay, although teeth used as bridge abutments commonly require full crown coverage.
If the nerve inside a supporting tooth is infected or irreversibly inflamed, root canal treatment may be necessary before the bridge is finalized.
Healthy Gums Are Important for Bridge Success
A bridge depends on healthy gum tissue around the supporting teeth or implants. Inflammation, deep periodontal pockets or bone loss can compromise the foundation of the restoration.
If active gum disease is present, periodontal treatment may be recommended before the final bridge is placed.
For deeper bacterial deposits below the gumline, scaling and root planing may be needed to create healthier conditions around the supporting teeth.
Replacing a Tooth After Extraction
If a tooth cannot be restored, tooth extraction may become the first step toward a bridge or another replacement.
Planning the replacement before the tooth is removed can help our dentist consider the condition of neighboring teeth, the expected shape of the gum tissue and whether an implant may be an alternative.
If implant treatment is being considered and bone volume is limited, bone grafting may also be discussed.
Caring for a Dental Bridge
The replacement tooth in a bridge cannot develop decay, but the natural teeth supporting it still can. Plaque can also accumulate around the gumline and beneath the pontic.
Daily cleaning should therefore include brushing and cleaning underneath the bridge with floss threaders, specialized floss or another device recommended by our team.
Regular general recare allows our dentist to monitor the bridge, supporting teeth, gums and bite over time.
How Long Can a Dental Bridge Last?
The lifespan of a bridge varies according to the condition of the supporting teeth, oral hygiene, bite forces and the design and material of the restoration.
Decay around an abutment tooth, periodontal disease or excessive grinding can shorten the life of a bridge. Consistent home care and professional monitoring can help identify problems before they become more difficult to treat.
If clenching, grinding or unusual bite forces are present, our dentist may recommend additional protection for the restoration.
Dental Bridges as Part of Larger Restorative Treatment
A bridge may be only one part of a broader treatment plan when several teeth are damaged or missing. Prosthodontic care can coordinate tooth replacement with crowns, implants, dentures and other restorations when multiple areas require treatment.
For extensive dental needs affecting many teeth, a comprehensive restorative plan may include several different procedures completed in stages.
Dr. Dwivedi has completed more than 500 bridges and more than 250 hours of continuing education related to prosthodontics and full-mouth restorative care.

Frequently Asked Questions About Dental Bridges
What is a dental bridge?
A dental bridge is a fixed restoration that replaces one or more missing teeth. The replacement tooth is connected to supporting crowns or implants on either side of the missing-tooth space.
How many teeth can a bridge replace?
A bridge may replace one or several neighboring missing teeth. The number depends on the location of the space, strength of the supports and forces placed on the restoration.
Do the teeth next to the gap have to be filed down?
For a traditional tooth-supported bridge, the neighboring teeth are generally prepared for crowns. Implant-supported bridges do not rely on natural teeth in the same way.
Is a dental bridge better than an implant?
Each option has different advantages. A bridge may be practical when neighboring teeth already need crowns, while an implant can replace a tooth without preparing adjacent healthy teeth. Our dentist can compare the options for your specific situation.
Does a dental bridge prevent bone loss?
A traditional bridge replaces the visible tooth but does not replace the root inside the jawbone, so it does not provide the same type of bone stimulation as a dental implant.
How do I clean under a dental bridge?
You need to clean beneath the replacement tooth as well as around the supporting teeth. Floss threaders, specialized floss or another interdental cleaner may be recommended.
How long do dental bridges last?
Longevity varies depending on the health of the supporting teeth, oral hygiene, bite forces and restorative material. Regular dental care helps monitor the bridge and surrounding tissues.
How do I find out whether a bridge is right for me?
