A dental bridge is a fixed dental restoration designed to replace one or more missing teeth by anchoring artificial teeth to adjacent natural teeth or dental implants. Australian adults aged 15 and over have an average of 5.7 missing teeth, with this figure increasing significantly with age. Dental bridges are an effective solution that restores your smile, improves chewing function, and prevents remaining teeth from shifting into gaps.

What Is a Dental Bridge?
A dental bridge is a prosthetic device that literally bridges the gap created by missing teeth. This type of dental restoration consists of artificial teeth (called pontics) that are held in place by dental crowns attached to the teeth on either side of the gap. Unlike removable dentures, a dental bridge is a fixed dental solution that stays permanently in your mouth.
The bridge helps restore your ability to chew properly, speak clearly, and maintain the natural shape of your face. When you lose teeth, the surrounding teeth can gradually shift into the space, causing bite problems and making it harder to clean between teeth. A dental bridge prevents this by filling the gap immediately.
Traditional dental bridges have been used for generations and remain one of the most common type of dental restoration available today. The bridge is used to replace one or more missing teeth while providing a natural appearance that blends seamlessly with your remaining natural teeth or dental implants.
Types of Dental Bridges
Several types of dental bridges are available, each designed for different situations. Understanding the different types of dental bridges helps you and your dentist determine which option suits your needs best.
1. Traditional Dental Bridge
A traditional bridge is the most common type of dental bridge used in Australia. This bridge type involves creating dental crowns for the teeth on either side of the gap, with the false teeth suspended between them. The two dental crowns are cemented onto the adjacent teeth, which are filed down slightly to accommodate the crowns.
Traditional dental bridges work brilliantly when you have healthy, natural teeth on both sides of the gap. They’re incredibly strong, and the bridge can last for many years with proper dental care. This fixed dental option provides excellent stability for chewing and speaking.
2. Cantilever Bridge Dental
A cantilever dental bridge is similar to a traditional bridge, but it’s only supported by one adjacent tooth instead of two. This cantilever bridge design is used when there are teeth on only one side of the gap. The pontic is supported by a crown on just one neighbouring tooth.
While this cantilever dental option can work well in specific situations, it’s not suitable for all areas of the mouth. Because all the support comes from one side, there’s more stress on the supporting tooth. Dentists typically recommend this bridge type for areas of your mouth that don’t experience heavy chewing forces.
3. Maryland (Resin-Bonded) Dental Bridge
A Maryland bridge is a more conservative alternative that doesn’t require extensive preparation of adjacent teeth. This resin-bonded bridge uses a metal or porcelain framework that’s bonded to the back of the teeth either side of the gap, rather than requiring full crowns.
The main benefit of a dental bridge like this is that it preserves more of your natural tooth structure. However, the adhesive bond can be less durable than traditional bridges, particularly in areas that experience significant biting force.
4. Implant-Supported Dental Bridge
An implant-supported bridge uses dental implants rather than natural teeth as anchors. Instead of being held in place by dental crowns on natural teeth, this bridge type is attached to dental implants that are surgically placed into your jawbone.
This bridge or an implant-supported option is considered the most stable and long-lasting type of bridge available. Because dental implants are anchored directly into the bone, they don’t rely on adjacent teeth for support. The dental bridge doesn’t require altering your natural teeth, and implant-supported bridges can last significantly longer than other bridge types.
Benefits of a Dental Bridge
Dental bridges are fixed prosthetics that offer numerous advantages for people with missing teeth. Here are the key benefits of dental bridges:
- Restores Function: A dental bridge can help you chew food properly and speak clearly again. Missing teeth often make it difficult to eat certain foods or pronounce words correctly.
- Prevents Teeth Shifting: When you lose teeth, the surrounding teeth naturally drift into the space. This can cause misalignment and bite problems. The bridge helps prevent this movement by filling the gap immediately.
- Maintains Face Shape: Missing teeth can cause your facial structure to change over time, leading to a sunken appearance. A dental bridge maintains the natural contours of your face.
- Improves Appearance: Getting a dental bridge restores your smile and boosts confidence. Modern bridges look incredibly natural and blend seamlessly with your existing teeth.
- Cost-Effective Solution: Compared to dental implants or removable dentures, many dental insurance plans provide better coverage for bridges, making them a more affordable option for many Australians.
The longevity of a dental bridge depends on proper care, but research shows the bridge can last for many years when maintained correctly.
Who Needs a Dental Bridge?
Candidates for dental bridges include anyone who’s lost one or more teeth and wants a permanent solution. You might be a good candidate if you have:
- One or more missing teeth with healthy teeth on either side
- Strong adjacent teeth or dental implants that can support the bridge
- Adequate bone density (particularly for implant-supported options)
- Good oral hygiene habits and commitment to regular dental check-ups
- Realistic expectations about the dental bridge procedure
However, if you’re considering a dental bridge, it’s essential to know if a dental bridge is right for your situation. Your dentist will evaluate whether a dental bridge is a great option by examining your oral health, bone structure, and overall dental condition.
People who grind their teeth heavily or have significant gum disease may need additional treatment before the bridge is placed. In 2023-24, private health insurance companies paid $3.6 billion in dental benefits for 51.9 million out-of-hospital dental services, highlighting how common dental restoration procedures like bridges have become in Australia.
Dental Bridge vs Other Tooth Replacement Options
When exploring alternatives to dental bridges, it’s helpful to understand how dental bridges compare to other solutions for missing teeth.
- Dental Bridges vs Dental Implants: While a dental bridge uses adjacent teeth for support, dental implants, instead of natural teet,h are surgically placed directly into the jawbone. Implants don’t require altering neighbouring teeth, but they involve surgery and typically cost more. However, dental implants or removable dentures each have specific advantages depending on your situation.
- Dental Bridges vs Dentures: Unlike removable false teeth, dental bridges are permanently fixed in place. Removable dentures can be taken out for cleaning, whilst bridges remain in your mouth all the time. Bridges typically feel more natural and don’t require the adjustment period that dentures often need.
- Fixed vs Removable Options: Dental bridges are fixed dental prosthetics that provide better stability than removable options. They don’t slip or move when you’re eating or speaking, offering greater comfort and confidence in daily activities.
The right choice between teeth or dental implants, bridges, or dentures depends on factors like your oral health, budget, lifestyle, and personal preferences. Your dentist can explain everything you need to know about dental solutions and help determine whether a dental bridge is the right option for you.
What Is the Dental Bridge Procedure Like?
The dental bridge procedure is typically completed over two or three visits to your dentist. Understanding the process helps you know what to expect.
- First Visit – Preparation: Your dentist examines your teeth and takes X-rays to ensure the adjacent teeth are healthy enough to support the bridge. The teeth on either side of the gap are then prepared by removing a small amount of enamel to make room for the crowns that will hold the bridge in place. Impressions of your teeth are taken and sent to a dental laboratory, where your custom bridge will be created. A temporary bridge is placed to protect your prepared teeth while the permanent bridge is ready.
- Laboratory Work: The dental lab uses your impressions to craft a bridge that matches your natural teeth in colour, shape, and size. This process typically takes 1-2 weeks.
- Second Visit – Placement: Once the permanent bridge is ready, you return to have it fitted. Your dentist removes the temporary bridge, checks the fit and appearance of your new bridge, and makes any necessary adjustments. When you’re both satisfied with how the bridge looks and feels, it’s cemented into place using dental cement.
Getting a dental bridge is generally not painful, as your dentist uses a local anaesthetic during the preparation phase. You might experience some sensitivity afterwards, but this usually subsides within a few days.
How Long Do Dental Bridges Last?
The dental bridge can last anywhere from 5 to 15 years on average, though some well-maintained bridges last much longer. Research shows that traditional fixed dental bridges have a 90% success rate after 5 years, with many lasting a decade or more.
Several factors influence how long your bridge will serve you:
- Material Quality: High-quality materials like porcelain fused to metal or zirconia tend to last longer than other options.
- Oral Hygiene: Proper brushing, flossing, and regular dental check-ups significantly extend the life of your bridge. The bridge may fail prematurely if decay develops in the supporting teeth.
- Bridge Type: Implant-supported bridges typically last the longest (15-30+ years) because dental implants, rather than natural teet,h provide more stable support. Traditional bridges generally last 10-15 years, whilst Maryland bridges may need replacement sooner.
- Lifestyle Factors: Habits like teeth grinding, chewing hard foods, or smoking can reduce the lifespan of your bridge. Your dentist might recommend a nightguard if you grind your teeth.
Proper care ensures the dental bridge may serve you well for many years. Regular dental visits allow your dentist to monitor the bridge’s condition and address any issues before they become serious problems.
Caring for a Dental Bridge
Maintaining your dental bridge requires commitment to excellent dental hygiene practices. Here’s how to keep your bridge in top condition:
- Daily Cleaning: Brush your teeth at least twice daily, paying special attention to the areas where the bridge meets your gums. Use a soft-bristled toothbrush and fluoride toothpaste. Floss daily using special floss threaders or interdental brushes to clean under and around the bridge where regular floss can’t reach.
- Use the Right Tools: Consider investing in a water flosser, which can effectively clean around your bridge. Antimicrobial mouthwash helps reduce bacteria and keeps your gums healthy.
- Regular Dental Visits: Schedule regular dental check-ups and professional cleanings every six months. Your dentist will examine your bridge, check the supporting teeth, and ensure everything remains healthy. Professional cleanings remove plaque and tartar that you can’t eliminate at home.
- Protect Your Bridge: Avoid chewing extremely hard foods like ice or hard lollies. If you play contact sports, wear a mouthguard to protect your teeth and bridge. Don’t use your teeth as tools to open packages or bottles.
- Watch Your Diet: Limit sugary and acidic foods that can cause decay in the teeth supporting your bridge. Eat a balanced diet rich in nutrients that support dental health and overall well-being.
Following these dental care guidelines helps ensure your investment lasts as long as possible. Remember, the teeth supporting your bridge need special attention because if they develop problems, your entire bridge may be affected.
Dental Bridge Before and After Results
Many Australians experience dramatic improvements in their quality of life after getting a dental bridge. Before treatment, people with missing teeth often struggle with:
- Difficulty chewing certain foods
- Embarrassment about their smile
- Speech problems affecting communication
- Gradual shifting of the remaining teeth
- Changes in facial appearance
After the bridge is placed, patients typically report:
- Restored the ability to eat comfortably
- Increased confidence in social situations
- Improved speech clarity
- Prevention of further dental problems
- A natural-looking smile that others can’t distinguish from real teeth
The transformation goes beyond just appearance. Research indicates that around 35% of Australian adults aged 15 years and over report feeling uncomfortable about their dental appearance, but dental bridges can significantly improve this aspect of quality of life.
“The psychological impact of replacing missing teeth shouldn’t be underestimated,” notes Dr Michael Chen, prosthodontist. “Patients often tell me that getting their bridge gave them the confidence to smile freely again.”
Conclusion
A dental bridge is a fixed dental restoration that effectively addresses the problem of missing teeth. Whether you need to replace one or more teeth, several types available can suit your specific situation. From the traditional bridge to the implant-supported bridge, each option provides distinct advantages.
Understanding everything you need to know about dental bridges, from the types of bridges to the care required, empowers you to make informed decisions about your dental health. With proper maintenance and regular dental visits, your bridge can last for many years, restoring both function and confidence to your smile.
