Not long ago the dental bridge was the alternative treatment of choice to partial dentures for restoring lost teeth. Over the last few decades, however, dental implants have nudged bridgework out of this premier spot.
That doesn’t mean, though, that bridgework has gone the way of the horse and buggy. In fact, it may still be a solid restorative alternative to partial dentures for certain people.
A traditional bridge consists of a series of porcelain crowns affixed to each other like pickets in a fence. The end crowns are fitted onto the teeth on either side of the empty tooth space; known as abutment teeth, they support the bridge. The crowns in the middle, known as pontics (from the French for “bridge”), replace the teeth that have been lost.
Bridges have been an effective and cosmetically pleasing method for tooth replacement for nearly a century. To achieve those results, though, a good portion of the abutment teeth’s structure must be removed to accommodate the crowns. This permanently alters these teeth, so they’ll require a restoration from that point on.
Dental implants, on the other hand, can be installed in the missing space without impacting any neighboring teeth. What’s more, implants provide greater support to the underlying bone than can be achieved with bridgework.
But not everyone is a viable candidate for implants, and ironically the reason most often has to do with the bone. If a patient has suffered significant bone volume loss, either because of disease or the long-term absence of the natural teeth, there may not be enough bone to properly support an implant. Unless we can adequately restore this lost bone volume through grafting, we’ll need to consider another type of restoration.
That’s where bridgework could be a viable option for patients in this or similar situations. With continuing advances in materials and new applications, the traditional bridge still remains an effective and important means to restore a smile marred by missing teeth.

In an instant, an accident could leave you or a loved one with a missing tooth. Thankfully, we can restore it with a dental implant that looks and functions like a real tooth—and the sooner the better.
But if the patient is a teenager or younger, sooner may have to be later. Because their jaws are still developing, an implant placed now could eventually look as if it's sinking into the gums as the jaw continues to grow and the implant doesn't move. It's best to wait until full jaw maturity around early adulthood and in the meantime use a temporary replacement.
But that wait could pose a problem with bone health. As living tissue, bone cells have a life cycle where they form, function and then dissolve (resorption) with new cells taking their place. This cycle continues at a healthy rate thanks to stimulation from forces generated by the teeth during chewing that travel through the roots to the bone.
When a tooth goes missing, however, so does this stimulation. Without it the bone's growth cycle can slow to an unhealthy rate, ultimately reducing bone volume. Because implants require a certain amount of bone for proper placement and support, this could make it difficult if not impossible to install one.
We can help prevent this by placing a bone graft immediately after the removal of a tooth within the tooth's "socket." The graft serves as a scaffold for new bone cells to form and grow upon. The graft will eventually resorb leaving the newly formed bone in its place.
We can also fine-tune and slow the graft's resorption rate. This may be preferable for a younger patient with years to go before their permanent restoration. In the meantime, you can still proceed with other dental treatments including orthodontics.
By carefully monitoring a young patient's bone health and other aspects of their dental care, we can keep on course for an eventual permanent restoration. With the advances in implantology, the final smile result will be worth the wait.
