OvercomingBoneLossPreventingYouFromGettinganImplant

Introduced to the United States in the 1980s, dental implants have quickly become the go-to restoration for tooth replacement. And for good reason: they're not only incredibly life-like, they're highly durable with a 95% success rate.

But as desirable as they are, you may face a major obstacle getting one because of the condition of the bone at your implant site. To position the implant for best appearance and long-term durability, we must have at least 4-5 mm of bone available along the horizontal dimension. Unfortunately, that's not always the case with tooth loss.

This is because bone, like other living tissue, has a growth cycle: Older cells die and dissolve (resorb) and newer cells develop in their place. The forces transmitted to the jaw from the action of chewing help stimulate this resorption and replacement cycle and keep it on track. When a tooth is lost, however, so is this stimulus.

This may result in a slowdown in cell replacement, causing the eventual loss of bone. And it doesn't take long for it to occur after tooth loss—you could lose a quarter of bone width in just the first year, leaving you without enough bone to support an implant. In some cases, it may be necessary to choose another kind of restoration other than implants.

But inadequate bone isn't an automatic disqualifier for implants. It's often possible to regenerate lost bone through a procedure known as bone augmentation, in which we insert a bone graft at the missing tooth site. The graft serves as a scaffold for new bone cells to grow upon, which over time may regenerate enough bone to support an implant.

Even if you've had a missing tooth for some time, implementing bone augmentation could reverse any loss you may have experienced. In fact, it's a common practice among dentists to place a bone graft immediately after a tooth extraction to minimize bone loss, especially if there will be a time lag between extraction and implant surgery.

Bone augmentation could add extra time to the implant process. But if successful, it will make it possible for you to enjoy this popular dental restoration.

GumRecessionCanRobYouofYourSmileandYourDentalHealthToo

If it seems like your teeth are getting longer as you get older, it's unlikely they're magically growing. More likely, your gums are shrinking or receding from your teeth. Besides the negative effect on your appearance, gum recession exposes you and vulnerable tooth areas to harmful bacteria and painful sensitivity.

Although common among older adults, gum recession isn't necessarily a part of aging: It's primarily caused by periodontal (gum) disease, in which infected gum tissues can weaken and detach from the teeth. This, along with bone loss, leads to recession.

But gum disease isn't the only cause—ironically, brushing your teeth to prevent dental disease can also contribute to recession. By brushing too aggressively or too often (more than twice a day), you could eventually damage the gums and cause them to recede. Tobacco use and oral piercings can also lead to weakened or damaged gums susceptible to recession.

You can lower your risk of gum recession by abstaining from unhealthy habits and proper oral hygiene to prevent gum disease. For the latter, your primary defense is gentle but thorough brushing and flossing every day to remove harmful dental plaque. You should also see your dentist at least twice a year for professional dental cleanings and checkups.

If, however, you do experience gum recession, there are a number of ways to restore your gums or at least minimize the recession. To start with, we must treat any gum disease present by thoroughly removing all plaque and tartar (calcified plaque), which fuels the infection. This reduces inflammation and allows the gums to heal.

With mild recession, the gums may rejuvenate enough tissue to recover the teeth during healing. If not, we may be able to treat exposed areas with a tooth-colored material that protects the surface, relieves discomfort and improves appearance.

If the recession is more advanced, we may still be able to stimulate gum regeneration by attaching a tissue graft with a micro-surgical procedure. These types of periodontal surgeries, however, can require a high degree of technical and artistic skill for best results.

In any event, the sooner we detect gum disease or recession, the quicker we can act to minimize the damage. Doing so will ensure your gums are healthy enough to protect your teeth and preserve your smile.

AfteraDevastatingInjuryPromptActionSavedSingerCarlyPearcesSmile

Performing for an awards show is a quite a feather in an entertainer's cap. So, up-and-coming country music star Carly Pearce was obviously excited when she gained a slot on last November's Country Music Awards. But an accident a couple of weeks before the event almost derailed her opportunity when she fell and knocked out two of her front teeth.

Fortunately, Pearce took quick action and, thanks to a skilled dental and medical team, was able to put her mouth back together before the show. Those watching her perform her hit single, “I Hope You're Happy Now,” as she smiled broadly would never have known otherwise about her traumatic emergency if she hadn't spilled the beans.

Orofacial injuries can happen to anyone, not just entertainers. You or someone you love could face such an injury from a motor vehicle accident, hard sports contact or, like Pearce, a simple slip and fall. But if you also act quickly like Pearce, you may be able to minimize the injury's long-term impact on dental health and appearance.

Here are some guidelines if you suffer a dental injury:

Collect any tooth fragments. Dental injuries can result in parts of teeth—or even a whole tooth—coming out of the mouth. It may be possible, though, to use those fragments to repair the tooth. Try to retrieve and save what you can, and after rinsing off any debris with cold water, place the fragments in a container with milk.

Re-insert a knocked-out tooth. You can often save a knocked-out tooth by putting it back in its socket as soon as possible. After cleaning off any debris, hold the tooth by its crown (never the root) and place it back in the empty socket. Don't fret over getting it in perfectly—your dentist will assist its placement later. Place a piece of clean cloth or cotton over the tooth and have the injured person bite down gently but firmly to hold it in place.

See the dentist ASAP. You should immediately see a dentist if any tooth structure has been damaged, or if a tooth is loose or has been moved out of place. If you're not sure, call your dentist to see if you should come on in or if you can wait. If a dentist is not available, go immediately to an emergency room or clinic. With many dental injuries, the longer you wait, the more likely the teeth involved won't survive long-term.

A dental injury could happen in a flash, with consequences that last a lifetime. But if, like Carly Pearce, you take prompt action and obtain necessary dental care, you could save an injured tooth—and the smile that goes with it.
