What are the advantages of bridges when compared to implants? 

  • Bridges are much less expensive than implants, especially if multiple teeth need to be replaced. 
  • So long as the teeth which are to be replaced have already been extracted, only one trip is required to have a bridge completed, whereas implants require two trips 3-6 months apart. 
  • If your bone has recessed at the site of the missing tooth, no bone grafting needed to place a bridge.  Implants may require grafting if your bone structure is poor.

What are the disadvantages of bridges when compared to implants?  

  • Bridgework compromises the integrity of the teeth that are used as anchors to support the bridge, both by removing material from the toot to place the bridge, and by causing more pressure and stress on the tooth than would normally be experienced. This can cause the supporting teeth to degrade or fail in the future. 
  • As there is no root in the bone or supporting the gums at the site of the missing tooth/teeth, the gums and bone will recede and atrophy over time. This can cause other teeth to fail, sunken looking spots in the jaw, and necessitate bone grafts should you want implants in the future. 
  • Bridges are not considered are permanent solution; they can require replacement after 10-15 years, especially if bone has resorbed or if the gum line has recessed.
  • Dental implants are considered to be a permanent solution to last a lifetime.
