If you have a missing tooth, two of the most popular permanent solutions are dental bridges and dental implants. Both can restore your smile and ability to chew, but they work in very different ways. Here is a detailed comparison to help you understand which option might be right for you.
What Is a Dental Bridge?
A dental bridge literally "bridges" the gap created by a missing tooth. It consists of a false tooth (pontic) held in place by crowns on the teeth on either side of the gap (abutment teeth). The adjacent teeth are filed down and crowned to support the bridge.
What Is a Dental Implant?
A dental implant is a titanium post surgically placed into the jawbone, acting as an artificial tooth root. Once the implant fuses with the bone (a process called osseointegration), a crown is attached on top to replace the visible tooth.
Head-to-Head Comparison
Procedure and Timeline
- Bridge: Completed in 2 visits over 1 to 2 weeks. No surgery needed.
- Implant: Requires surgery and a healing period of 3 to 6 months before the final crown is placed. Total process takes 4 to 8 months.
Impact on Adjacent Teeth
- Bridge: Requires filing down the two adjacent teeth, removing healthy tooth structure permanently. This is the main disadvantage.
- Implant: Does not affect adjacent teeth at all. It stands independently in the jawbone.
Durability and Lifespan
- Bridge: Typically lasts 7 to 15 years. May need replacement when the supporting teeth develop problems.
- Implant: The implant itself can last a lifetime with proper care. The crown on top may need replacement after 10 to 15 years.
Bone Preservation
- Bridge: Does not stimulate the jawbone in the gap area. Bone loss continues beneath the pontic over time.
- Implant: Stimulates the jawbone like a natural tooth root, preventing bone loss.
Cost
- Bridge (3-unit): From approximately $1,800 to $2,400 (3 crowns)
- Implant (single): From $2,449 total for an Osstem implant ($499 after Medisave) or $3,449 for Straumann ($1,499 after Medisave) at Trust Dental Surgery
Medisave advantage: Dental implant surgery is Medisave claimable up to $1,950 per implant, which significantly reduces the out-of-pocket cost. Bridges are generally not Medisave claimable. When you factor in Medisave, an implant can be surprisingly affordable.
Maintenance and Cleaning
- Bridge: Requires special flossing techniques (floss threaders or superfloss) to clean under the pontic. Food can get trapped underneath.
- Implant: Cleaned just like a natural tooth with regular brushing and flossing.
When Is a Bridge the Better Choice?
- The adjacent teeth already need crowns anyway (due to large fillings or damage)
- You want a faster, non-surgical solution
- You have medical conditions that make implant surgery risky
- There is insufficient bone for an implant and you prefer not to have a bone graft
When Is an Implant the Better Choice?
- The adjacent teeth are healthy and you do not want to file them down
- You want the longest-lasting solution
- You want to preserve jawbone
- You want to use Medisave to reduce out-of-pocket costs
- You are replacing multiple non-adjacent teeth (each implant is independent)
Our Recommendation
For most patients with a single missing tooth and healthy adjacent teeth, a dental implant is the gold standard. It preserves your natural teeth, prevents bone loss, and lasts the longest. With Medisave coverage, the cost difference between a bridge and an implant is often smaller than people expect.
However, a bridge remains an excellent option in certain situations, particularly when the adjacent teeth already need crowns. Your dentist will assess your specific case and recommend the best option during your consultation.
