TeensMayNeedaTemporaryRestorationforMissingTeeth

While not as prevalent as adults, teenagers can have missing teeth, usually from injury or from never having been formed. Fortunately, life-like dental implants can replace missing teeth. But unfortunately for teens, implants aren't usually a good option—yet.

That's because a teenager's jaws are still growing, and will continue until early adulthood. Dental implants don't adjust to this growth like natural teeth and will eventually look out of place. It's best, then, to consider a temporary restoration for a teenager. And, there are two excellent options: one removable and one fixed.

The first is a removable partial denture (RPD). Like a full denture, an RPD has an acrylic base that resembles gum tissue, to which prosthetic (false) teeth are attached to match the positions of the missing teeth. It's usually held in place with metal or nylon clips that slide under part of the natural teeth at the gum line.

RPDs are versatile and durable. But they're not designed to be worn indefinitely, so they can be damaged if subjected to excessive biting forces like biting into something hard. And, peer-pressured teens may also feel self-consciousness about wearing a “denture.”

The other option is a bonded bridge. It's similar to a traditional bridge, except how it's supported in the mouth. A traditional bridge gains its support from the crowns on each end attached to natural teeth, which must be permanently altered for them. By contrast, a bonded bridge has strips of dental material extending from both sides of its back that are bonded to the back of the adjacent natural teeth.

With the bonding material behind the bridge, it can't be seen—and the natural teeth won't require permanent alteration. But a bonded bridge is usually more costly than an RPD and less secure than a traditional bridge. And not every teen is a viable candidate for one: issues like how the teeth fit together and if the teen has a tooth grinding habit could be strikes against this fixed option.

Your dentist can help you sort out the best of these options for your teen. If cared for and maintained properly, either restoration can buy you time until your teen is ready for dental implants.

JamieFoxxChipsaTooth-ThisTimebyAccident

Some people are lucky — they never seem to have a mishap, dental or otherwise. But for the rest of us, accidents just happen sometimes. Take actor Jamie Foxx, for example. A few years ago, he actually had a dentist intentionally chip one of his teeth so he could portray a homeless man more realistically. But recently, he got a chipped tooth in the more conventional way… well, conventional in Hollywood, anyway. It happened while he was shooting the movie Sleepless with co-star Michelle Monaghan.

“Yeah, we were doing a scene and somehow the action cue got thrown off or I wasn't looking,” he told an interviewer. “But boom! She comes down the pike. And I could tell because all this right here [my teeth] are fake. So as soon as that hit, I could taste the little chalkiness, but we kept rolling.” Ouch! So what's the best way to repair a chipped tooth? The answer it: it all depends…

For natural teeth that have only a small chip or minor crack, cosmetic bonding is a quick and relatively easy solution. In this procedure, a tooth-colored composite resin, made of a plastic matrix with inorganic glass fillers, is applied directly to the tooth's surface and then hardened or “cured” by a special light. Bonding offers a good color match, but isn't recommended if a large portion of the tooth structure is missing. It's also less permanent than other types of restoration, but may last up to 10 years.

When more of the tooth is missing, a crown or dental veneer may be a better answer. Veneers are super strong, wafer-thin coverings that are placed over the entire front surface of the tooth. They are made in a lab from a model of your teeth, and applied in a separate procedure that may involve removal of some natural tooth material. They can cover moderate chips or cracks, and even correct problems with tooth color or spacing.

A crown is the next step up: It's a replacement for the entire visible portion of the tooth, and may be needed when there's extensive damage. Like veneers, crowns (or caps) are made from models of your bite, and require more than one office visit to place; sometimes a root canal may also be needed to save the natural tooth. However, crowns are strong, natural looking, and can last many years.

But what about teeth like Jamie's, which have already been restored? That's a little more complicated than repairing a natural tooth. If the chip is small, it may be possible to smooth it off with standard dental tools. Sometimes, bonding material can be applied, but it may not bond as well with a restoration as it will with a natural tooth; plus, the repaired restoration may not last as long as it should. That's why, in many cases, we will advise that the entire restoration be replaced — it's often the most predictable and long-lasting solution.

Oh, and one more piece of advice: Get a custom-made mouthguard — and use it! This relatively inexpensive device, made in our office from a model of your own teeth, can save you from a serious mishap… whether you're doing Hollywood action scenes, playing sports or just riding a bike. It's the best way to protect your smile from whatever's coming at it!

YourQuestforaDentalImplantMightBeInterruptedbyBoneLoss

Years ago, disease or trauma robbed you of one of your teeth. At the time you might have opted for an affordable solution, like a partial denture. But now you'd like to restore that missing tooth with a dental implant, the most life-like tooth replacement available.

That's a great decision. But there may be a hiccup along the way to your new implant: the state of the underlying jawbone. Implants need a certain amount of bone for proper placement. If not enough is present, that may cause an interruption in your plans—and that could be a real possibility if your tooth has been missing for some time.

That's because, like other living tissues, bone has a growth cycle: Old bone cells die and dissolve, while new cells form to take their place. In the jaw, the force produced by teeth during chewing helps to keep this growth process in the bone functioning at a healthy pace.

When a tooth goes missing, though, so does this chewing stimulation. A lack of stimulation can slow the growth rate for that part of the bone and its volume can diminish over time. It's possible for a quarter of the bone volume to be lost within the first year after losing a tooth.

If you've experienced that level of bone loss, we may not be able to place an implant—yet. You might still have a few options. For one, we could attempt to regenerate some of the bone through grafting. Bone material grafted into the affected area can serve as a scaffold for new bone cells to form and adhere. Over time, this could result in a sufficient amount of regenerated bone to support a dental implant.

Another possibility might be to install a smaller diameter implant like those used to support removable dentures. Because they're smaller they require less bone than standard-sized implants. They're not for every situation, though, and are best suited for situations where aesthetics isn't a priority.

To know what your options are regarding an implant-based restoration, you'll need to undergo a thorough evaluation of your oral health, including supporting bone. Depending on your situation, you may still be able to renew your smile with this premier tooth replacement option.
