The primary disadvantages of a dental bridge revolve around its impact on the underlying bone structure and its overall longevity compared to other tooth replacement options like implants.
Jawbone Deterioration
One significant disadvantage of a dental bridge is that it does not stimulate the jawbone beneath the missing tooth. Because bridges sit above the gum line, the jawbone will continue to deteriorate over time. This bone loss can lead to a sunken appearance in the jaw area, potentially affecting facial structure and the fit of the bridge in the long run. Unlike natural teeth or dental implants which integrate with the bone, a bridge only replaces the visible part of the tooth.
Shorter Lifespan
Another key drawback of dental bridges is their limited lifespan when compared to dental implants. Bridges are not as long-lasting as implants. While dental implants are expected to last more than 25 years, bridges have a lifespan of about 15 years at the most. This means that a dental bridge may need to be replaced more frequently, potentially leading to additional costs and procedures over time.
To illustrate the difference in longevity:
Lifespan Comparison: Dental Bridge vs. Dental Implant
Restoration Type | Estimated Lifespan |
---|---|
Dental Bridge | Up to 15 years |
Dental Implant | Over 25 years |
Considering these points, while dental bridges offer an effective solution for replacing missing teeth, their impact on jawbone health and their shorter durability are important factors to consider.
