There are plenty of options today for replacing missing teeth, including dental implants. But if the teeth have been missing for some time, complications can arise that limit your restorative options.
The most consequential possibility is bone loss. Bone has a life cycle: old cells dissolve (resorb), and are then replaced by new cells, stimulated to grow by the forces applied to the teeth during chewing. But the bone won't receive this stimulation if a tooth is missing — so growth slows down, which causes the bone volume to diminish with time.
Another complication can occur involving other teeth around the open space. These teeth will naturally move or “drift” out of their normal position into the missing tooth space. As a result we may not have enough room to place a prosthetic (false) tooth.
If either or both of these complications occur, we'll need to address them before attempting a restoration. Bone loss itself could eliminate dental implants as an option because they require a certain amount of supporting bone for correct placement. Bone loss could also make correcting misaligned teeth difficult if not impossible.
It might be possible, though, to regenerate lost bone with a bone graft. The graft is placed, sometimes along with growth stimulating substances, within the diminished bone area. It then serves as a scaffold upon which new bone can form.
If the bone becomes healthy again, we can then attempt to move any drifted teeth back to where they belong. Besides braces, there's another treatment option especially popular with adults: clear aligners. These are a series of removable, clear plastic trays that, like braces, exert gradual pressure on the teeth to move them. Patients wear each individual tray for about two weeks, and then switch to the next tray in the series to continue the process.
Unlike their traditional counterparts, clear aligners can be removed for cleaning or for special occasions. More importantly, they're much less noticeable than traditional braces.
Once any problems with bone health or bite have been addressed and corrected, you'll have a fuller range of options for replacing your missing teeth. With a little extra time and effort, you'll soon be able to regain a smile you'll be proud to display.
Dental implants are widely considered by both dentists and patients as the premier choice for replacing missing teeth. Unfortunately, implants aren’t the appropriate choice for teenagers with missing teeth.
That’s because their jaws won’t fully finish most of their growth and development until early adulthood. An implant placed too early could become misaligned as the jaw matures. The best approach for a teenager is a temporary restoration until they’re old enough for an implant.
There are a couple of good options. One is a removable partial denture (RPD), prosthetic (false) teeth set in an acrylic base that mimics gum tissue at the locations of the missing teeth. RPDs, which stay in place by way of metal clips that fit over other teeth, are easy to wear and maintain.
On the downside, an RPD can break if you bite into something too hard. They can lose their fit and may need to be replaced with a new one. And, some teens aren’t quite keen on wearing a “denture.”
Another option is a bonded or Maryland bridge, a kind of fixed bridge. We bond dental material to the back of a prosthetic tooth with portions of the material extending out from either side of it.Â We then bond these extending tabs to the back of the teeth on either side of the prosthetic tooth to hold it in place. Unlike traditional bridges, we can eventually remove it without any permanent alterations to the teeth it’s attached to.
Before we undertake a bonded bridge, though, we must make sure the gums and bone of the surrounding teeth are free from periodontal (gum) disease and are healthy and strong enough to support the bridge. We also need to be sure the patient doesn’t have a deep bite or a teeth grinding habit, which could cause the teeth to make contact with the tabs and break them.
The patient also needs the maturity to responsibly perform diligent oral hygiene: this type of bridge has a tendency to build up disease-causing plaque, so brushing twice and flossing once every day is critical. Not doing so increases the risk of tooth decay or periodontal (gum) disease, which could complicate a future implant.
We can discuss these options after a thorough dental examination of your teenager. Either way, we’ll be able to restore your teen’s smile until we can undertake a more permanent restoration.
