What are the most common bridge complications?

According to some studies, bridges have an average life span of about 6.7 years. This is due to frequrent recurrent caries, root canal complications, and excessive forces that are common to bridges. Generally, I don't recommend them. Dental implants are now the standard of care for tooth replacement and if properly done can have lifetime results.  Please see our website in the implant section for some very insightful information on the difference.

There are no significant complications from getting a bridge over an implant.  Both have risks and benefits.

A bridge requires reduction of the teeth adjacent to the missing tooth area to support and hold the bridge in place.  We recommend this option in our office when the adjacent teeth have already been heavily restored and may require crowns in the not too distant future.  The risks include recurrent decay of the bridge/ tooth margin due to poor hygiene or damage to the porcelain surface.

An implant is used to replace a missing tooth without involving adjacent teeth.  This is a great option when the adjacent teeth have no restorative concerns or potential.  Risks here include failure of the implant to heal into the bone, infection of the implant site and damage to the restoring crown.

Both methods are equally safe and require the same precautions as for natural teeth when you are involved in contact sports.

The number one complication or cause of failure of a dental bridge is decay under one of the adjacent teeth. 

A dental bridge is a form of replacement of a tooth that utilizes adjacent teeth as abutments.  Because of the inability to floss between the connected teeth, the abutment teeth are very susceptible to decay.  The decay can very easily lead to pulp (nerve) necrosis (death) and may result in a need to preform root canal therapy. 

A dental implant replacement avoids this problem as it is much easier to clean around a dental implant than it is around a bridge.
