Dental Bridges: What You Need to Know
What Is a Dental Bridge?
A dental bridge is a fixed dental restoration used to replace one or more missing teeth. It literally “bridges” the gap left by a missing tooth using a false tooth (called a pontic) supported by the surrounding natural teeth or dental implants.
Bridges are custom-made to match the size, shape, and color of your natural teeth, allowing them to blend seamlessly into your smile.
Why Might You Need a Dental Bridge?
You may be a good candidate for a dental bridge if you:
- Have lost a tooth due to decay, trauma, or gum disease
- Want a non-removable option (unlike dentures)
- Have healthy teeth or implants on either side of the gap
- Want to restore full function to your bite and smile
Leaving a gap in your smile untreated can lead to:
- Teeth shifting out of place
- Difficulty chewing or speaking
- Increased risk of decay and gum disease
- Jawbone loss over time
Bridges help maintain alignment, restore functionality, and boost confidence.
Types of Dental Bridges
There are several types of bridges, and your dentist will recommend the best one based on your situation:
1. Traditional Bridge
This is the most common type. It uses two crowns placed on the healthy teeth (called abutment teeth) on either side of the gap. A false tooth is placed in between.
- Best for: Patients with natural teeth on both sides of the missing tooth.
- Pros: Strong and long-lasting.
- Cons: Requires reshaping the surrounding healthy teeth.
2. Cantilever Bridge
This type uses only one adjacent tooth to support the bridge. It's less common and typically used in areas of the mouth that experience less pressure, like the front teeth.
- Best for: When there’s only one healthy tooth next to the gap.
- Pros: Less invasive than a traditional bridge.
- Cons: May not be as stable under chewing forces.
3. Maryland Bridge (Resin-Bonded Bridge)
Instead of using crowns, this bridge uses metal or porcelain "wings" that are bonded to the back of the adjacent teeth.
- Best for: Replacing front teeth.
- Pros: Minimally invasive; little to no alteration of neighboring teeth.
- Cons: Not as strong; can detach under stress.
4. Implant-Supported Bridge
Instead of using natural teeth, this bridge is anchored by dental implants placed in the jawbone. It's a durable and stable solution for patients missing multiple teeth.
- Best for: Patients missing several teeth in a row.
- Pros: Extremely strong and long-lasting.
- Cons: More expensive and involves a surgical procedure.
The Dental Bridge Procedure: What to Expect
The process of getting a dental bridge typically involves two or more dental visits:
Step 1: Consultation and Exam
Your dentist will evaluate your teeth, gums, and bone structure to determine if a bridge is the best option. They may take X-rays and impressions.
Step 2: Tooth Preparation
If you’re getting a traditional bridge, the adjacent teeth will be reshaped to fit the crowns. If implants are being used, this step will involve implant placement and healing time.
Step 3: Temporary Bridge
While the permanent bridge is being made, your dentist may place a temporary bridge to protect the area.
Step 4: Final Placement
Your custom bridge will be fitted, adjusted, and cemented into place. Your bite will be checked, and your dentist will give you care instructions.
Benefits of Dental Bridges
Choosing a dental bridge comes with many advantages:
Restore Your Smile
Say goodbye to hiding your teeth. A bridge helps bring back your confidence when speaking, laughing, or taking photos.
Improve Chewing and Speaking
Missing teeth can make eating certain foods painful or difficult. Bridges help you chew naturally and speak clearly.
Prevent Teeth from Shifting
Gaps in your smile cause neighboring teeth to drift, which can lead to misalignment. Bridges help maintain proper spacing.
Preserve Facial Structure
Tooth loss can cause sagging in the cheeks or lips. Replacing teeth helps maintain the shape of your face.
How Long Do Dental Bridges Last?
With good care, a dental bridge can last 5 to 15 years or even longer. Some key factors that affect longevity include:
- Oral hygiene habits
- Diet (avoiding very hard or sticky foods)
- Regular dental visits for cleanings and exams
- Avoiding bad habits like nail biting or chewing ice
