Dental bridge versus dental implant
When a tooth is lost or needs extracting, two of the most common fixed replacement options are a dental bridge and a dental implant. Both can restore function and appearance — but they work differently and suit different patients.
What each option involves
A dental bridge is a fixed restoration that spans the gap left by a missing tooth. It is supported by crowns fitted on the natural teeth on either side of the gap (the abutment teeth). A dental implant replaces the tooth root with a titanium post placed in the jawbone, onto which a crown is attached once the implant has integrated with the bone.
The key difference: adjacent teeth
A bridge requires preparation (drilling) of the adjacent teeth to create space for the supporting crowns. These teeth must be permanently crowned, even if they are otherwise healthy. An implant does not involve adjacent teeth at all.
Bone loss over time
When a tooth is lost, the bone beneath it gradually resorbs. A bridge does not prevent this process. A dental implant integrates with the bone and provides a degree of stimulation that may slow bone resorption in the area. This can be relevant for long-term facial structure and for the stability of the replacement.
Which has a longer lifespan?
Both options have variable longevity. Bridges can last many years but may eventually need replacing — and the abutment teeth under the supporting crowns can be prone to decay or further damage. Implants, with proper maintenance, can last considerably longer in suitable patients. No specific lifespan can be guaranteed for either option.
Which is right for you?
The right option depends on the condition of adjacent teeth, the volume of bone available, your general health, your timeline and budget. A thorough consultation and assessment with Dr Assaker will identify which option is clinically suitable and help you understand the trade-offs. Some patients are not suitable for implants (insufficient bone, medical factors) and a bridge is the more appropriate choice.

Suitability for implants or bridges varies individually. A clinical assessment is required before treatment is recommended. Results and longevity vary and cannot be guaranteed.
