What Is a Dental Bridge?
What Is a Dental Bridge?
A dental bridge is a fixed dental restoration used to replace one or more missing teeth by anchoring artificial teeth (called pontics) to the adjacent natural teeth or implants (called abutments). Think of it like a bridge over a river: the two supports on either side are the abutment teeth, and the replacement tooth sits in the middle.
Dental bridges are cemented into place, meaning they are not removable like dentures, and they are custom-made to match the color, shape, and size of your natural teeth.
Why Would You Need a Dental Bridge?
Missing teeth can cause more than cosmetic concerns. Here are a few reasons why your dentist might recommend a dental bridge:
- Restore your smile
- Improve chewing and speaking ability
- Maintain the shape of your face
- Prevent remaining teeth from shifting
- Improve bite alignment
Over time, gaps from missing teeth can cause the surrounding teeth to drift, which may lead to bite problems, jaw pain, or difficulty chewing. A dental bridge helps prevent these issues.
Types of Dental Bridges
There are several types of dental bridges available, each suited for different situations:
1. Traditional Dental Bridge
This is the most common type. It consists of one or more pontics held in place by dental crowns cemented onto the natural teeth adjacent to the gap. These adjacent teeth must be filed down to accommodate the crowns.
Best for: Replacing teeth where healthy natural teeth are on both sides of the gap.
2. Cantilever Dental Bridge
Similar to a traditional bridge, but the pontic is supported by a crown on only one adjacent tooth.
Best for: Situations where there’s only one healthy tooth next to the gap. Less commonly used due to stress on the supporting tooth.
3. Maryland Bonded Bridge (Resin-Bonded Bridge)
This type uses a metal or porcelain framework bonded to the back of adjacent teeth, without the need to file them down.
Best for: Front teeth, where stress on the bridge is minimal.
4. Implant-Supported Bridge
Instead of relying on natural teeth, this bridge is anchored with dental implants. It’s a great solution when multiple teeth are missing.
Best for: Patients who are missing multiple teeth and want a stable, long-lasting solution.
What Is the Procedure Like?
Getting a dental bridge typically involves two or more visits to your dentist:
1. Initial Consultation and Preparation
Your dentist will examine your mouth, take X-rays, and assess whether a dental bridge is right for you. If a traditional bridge is recommended, the abutment teeth are prepared by removing some enamel to make room for crowns.
2. Impressions and Temporary Bridge
Your dentist will take impressions of your teeth and send them to a dental lab to create a custom bridge. Meanwhile, a temporary bridge may be placed to protect your exposed teeth and gums.
3. Bridge Placement
Once your permanent bridge is ready (usually in 1-2 weeks), the temporary one is removed and the permanent bridge is fitted and adjusted for proper bite and comfort. It is then cemented into place.
How Long Do Dental Bridges Last?
With proper care, dental bridges can last anywhere from 5 to 15 years, or even longer. The lifespan depends on the materials used, your oral hygiene habits, and how well you maintain your dental health.
Caring for Your Dental Bridge
A dental bridge needs the same care as your natural teeth. Here are some tips:
- Brush twice a day with fluoride toothpaste
- Floss daily, especially under the bridge using floss threaders or special bridge floss
- Use antibacterial mouthwash to reduce plaque
- Visit your dentist regularly for check-ups and cleanings
- Avoid hard or sticky foods that might damage the bridge
Maintaining strong and healthy teeth around the bridge is crucial — they provide the support needed to keep the bridge in place.
Pros and Cons of Dental Bridges
Pros:
- Restores function and appearance
- Quick, non-surgical option (compared to implants)
- Less expensive than implants
- Customized to match your natural teeth
Cons:
- Requires alteration of healthy teeth (except implant-supported or Maryland bridges)
- May need replacement after 10–15 years
- Does not prevent bone loss in the jaw (unlike implants)
Dental Bridge vs. Implant: Which One Should You Choose?
If you're deciding between a dental bridge and a dental implant, here are a few considerations:
- Dental Bridges are faster to complete and less invasive.
- Dental Implants provide better long-term bone health and don’t require modifying adjacent teeth.
- Cost, bone structure, and overall oral health will influence your choice. Your dentist will help you choose the best option for your situation.
Is a Dental Bridge Right for You?
A dental bridge can be a great option if you're missing one or more teeth and want a quick, effective way to restore your smile. It’s particularly ideal for patients who have healthy teeth adjacent to the gap or for those who may not be good candidates for implants.
To know for sure, schedule a consultation with your dentist. They will evaluate your oral health, discuss your options, and help you make an informed decision.
