What Is a 3-Unit Bridge?
A 3-unit bridge is a fixed dental restoration used to replace one missing tooth. It is called “3 unit” because it consists of three fused crowns:
The middle crown replaces the missing tooth.
The two outer crowns attach to the natural teeth on each side, acting as support pillars.
This type of bridge is ideal for patients who have a single gap but still have healthy teeth on both sides. It restores chewing function, improves appearance, and prevents surrounding teeth from shifting out of place.
Compared to implants, a 3-unit bridge offers a faster and more budget-friendly approach, while still providing reliable long-term results.
How a 3-Unit Bridge Works
The process is simple and usually completed in two visits:
Tooth Preparation:
The two supporting teeth (abutments) are gently shaped to hold the crowns.Digital Smile Design:
We create a digital preview of your final bridge before treatment begins. This allows you to visualize your new smile and ensure the result matches your facial features and cosmetic goals.Impressions or Scanning:
A digital scan or impression is taken to design the custom bridge with the ideal shape and color.Temporary Bridge:
A temporary bridge is placed while the definitive one is fabricated.Final Placement:
On your second visit, the permanent 3-unit bridge is cemented securely, restoring function and aesthetics immediately.
This restoration blends naturally with the rest of your teeth, making the result look seamless and natural.
Benefits of a 3-Unit Bridge
Choosing a 3-unit bridge provides several important advantages:
Fast replacement of a missing tooth
Non-surgical option
Improves chewing and speaking
Prevents teeth from drifting into the empty space
Restores facial symmetry
Custom-matched color for a natural appearance
More affordable than implant-based options
For many patients, it is a practical and predictable solution to restore their smile.
3 Tooth Bridge Cost
The cost of a 3-tooth bridge varies depending on materials, the dentist’s expertise, and the country where you receive treatment.
In the United States, a porcelain-fused-to-metal or zirconia 3-unit bridge can range between $4,000 and $5,500 USD.
At our dental clinic in Tijuana, patients typically save between 60% and 70% compared to U.S. prices, while still receiving high-quality materials like zirconia and porcelain.
Tijuana is one of the most popular destinations for dental tourism precisely because the quality and precision match U.S. standards, without the high cost.
3-Unit Bridge Cost With Insurance
Many PPO dental insurance plans may offer partial coverage for a 3-unit bridge since this treatment is considered restorative and not purely cosmetic.
Coverage may depend on several factors:
Your specific PPO plan
Annual maximums
Waiting periods
Whether the missing tooth clause applies
The type of materials used
Whether you have used other benefits during the year
We can help you verify whether your PPO insurance can reimburse or assist with the cost of your 3-unit bridge.
Even though treatment is performed in Mexico, many PPO plans still allow reimbursement for out-of-network services.
This gives patients a major advantage: lower Mexico prices + possible insurance reimbursement = higher savings overall.
Types of Materials for a 3-Unit Bridge
Depending on your needs and budget, several materials are available:
Zirconia Bridges
Extremely strong and biocompatible
Excellent translucency and natural aesthetics
Ideal for front and back teeth
All-Porcelain Bridges
Best for highly aesthetic cases
More suitable for front teeth
Your dentist will discuss which option provides the right balance of beauty and durability.
