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.

What happens when you lose a tooth? In the short-run, it can certainly undermine your appearance and ability to efficiently chew and digest food. But a chain of events could also be set in motion that may cause the most harm to your appearance and health—and it all has to do with bone loss.
Our bones aren't just rigid structures providing a frame for our bodies. They're living tissue with other purposes like producing blood cells and regulating the endocrine system. Bone tissue is constantly replenishing itself as older cells die and newer ones take their place.
In the jawbone, the pressure generated by the teeth while biting and chewing travels through the roots to stimulate the growth of new bone. If a tooth goes missing, however, the bone around the tooth also loses this growth stimulus.
This can cause normal bone growth to slow so that dying bone cells aren't sufficiently replaced. The bone may then diminish at an alarming rate—a decrease in width of about 25% in the first year after a tooth loss and several millimeters in height after only a few years.
This bone loss can continue to advance, especially if multiple teeth are lost, until the jaw structure as a whole loses significant height. The bite may then collapse, forcing the front teeth to push forward. In this state, a person may not be able to adequately bite or chew food. It can also damage their appearance—their smile suffers, of course, but their entire face may also appear shrunken.
You may be able to avoid this scenario if you replace missing teeth with dental implants. In addition to their life-likeness and durability, implants can also stop or slow bone loss. This is because titanium, the principle metal used in an implant, has a strong affinity with bone: Bone cells readily grow and attach to the titanium surface and foster new growth.
But don't wait: Bone loss could eventually extend beyond what an implant can accommodate—you may then need grafting to build up the bone or consider a different type of restoration. So, speak with your dentist as soon as possible about an implant restoration for a lost tooth to help avoid significant bone loss.

After years battling disease, your troubled tooth reached its useful life's end. It's been extracted, and we've replaced it with a life-like dental implant. So now, as far as the implant goes, disease is no longer an issue…right?
Sorry, no—though not to the same degree as a natural tooth, an implant could be endangered by gum disease. Although the implant's materials can't be infected, the supporting gums and bone can.
In fact, there's a particular type of gum disease associated with implants known as peri-implantitis (“peri” around an implant; “itis” inflammation) that first affects the gums surrounding an implant. Although peri-implantitis can arise from an excess of dental cement used to affix the crown to the implant, it most commonly starts like other forms of gum disease with dental plaque.
Dental plaque, and its hardened form calculus (tartar), is a thin, bacterial biofilm that builds up on teeth surfaces. It can quickly accumulate if you don't remove it every day with proper brushing and flossing. The bacteria living in plaque can infect the outer gum tissues and trigger inflammation.
Gum disease around natural teeth can spread quickly, but even more so with implants. That's because the natural attachment of the gums helps supply antibodies that impede infection. Implants, relying solely on their connection with the bone, don't have those gum attachments. As a result, peri-implantitis can move rapidly into the supporting bone, weakening the implant to the point of failure.
The good news, though, is that peri-implantitis can be treated successfully through aggressive plaque removal and antibiotics. But the key to success is to catch it early before it progresses too far—which is why you should see your dentist at the first sign of gum swelling, redness or bleeding.
You can also prevent peri-implantitis by practicing daily brushing and flossing, including around your dental implant. You should also see your dentist twice a year (or more, if they advise) for cleanings and checkups.
Dental implants overall have a greater than 95% success rate, better than any other tooth restoration system. But they still need daily care and regular cleanings to ensure your implants are on the positive side of those statistics.
The subject of allergies covers a wide swath in medicine. Among other things, people have allergic reactions to animal fur, various foods and plant pollen. The effects are equally wide-ranging, anything from a mild rash to anaphylaxis, a life-threatening shutdown of the body's vital systems.
Approximately 5% of people are also allergic to various metals including nickel, cobalt, chromium and gold. Reactions to metal can occur when an allergic person comes in contact with items like jewelry, clothing or even mobile phones. There's even a chance of a metal allergy reaction from certain kinds of dental work.
It's unlikely, though, that you should be concerned if you're considering dental treatment or cosmetic work to upgrade your smile. Although allergic reactions like inflammation or a rash have been known to occur with amalgam “silver” fillings, it's quite rare. It's even less of a concern since “tooth-colored” materials for fillings are now outpacing the use of amalgam fillings, which are used in out-of-sight back teeth.
Of course, metal is used for other dental treatments besides fillings, including the most popular of tooth replacement systems, dental implants. An implant is essentially a metal post, usually made of pure titanium or a titanium alloy, which is imbedded into the jawbone. Even so, there's little chance you'll develop an allergic reaction to them.
For one thing, titanium is highly prized in both medical and dental treatments because of its biocompatibility. This means titanium devices like prosthetic joints and implants won't normally disrupt or cause reactions with human tissue. Titanium is also osteophilic: Bone cells readily grow and adhere to titanium surfaces, a major reason for dental implants' long-term durability.
That's not to say titanium allergies don't exist, but their occurrence is very low. One recent study detected a titanium allergy in only 0.6% of 1,500 implant patients who participated.
At worst, you may need to consider a different type of tooth replacement restoration in the rare chance you have a titanium allergy. More than likely, though, you'll be able obtain implants and enjoy the transformation they can bring to your smile.

Here's the bad news on the overall state of dental health in the United States: Over 120 million people have one or more missing teeth—roughly one American in three. But there's also good news: We can replace missing teeth with a number of effective restorative methods. At the top of the list are dental implants, highly regarded by dentists and patients alike as the most lifelike and functional tooth replacement system available.
Dental implants have been growing in popularity since their introduction in the 1980s. Their structural design and construction have continued to improve, giving patients even more options for implant-based tooth replacement.
To bring greater attention to the benefits of this popular restoration, the American Academy of Implant Dentistry (AAID) designated August as Dental Implant Month in 2016. In recognition, here are 3 of those benefits you might gain from choosing dental implants to replace your missing teeth.
Durability. Unlike other restorations such as conventional dentures or bridges, implants replace the entire root structure of the tooth. To be more precise, implants are a tooth root replacement in the form of a post imbedded securely in the jawbone. As the bone grows around and attaches to the implant, it develops a durable and highly functional hold that can last for decades.
Adaptability. Many people assume dental implants are used only to replace individual teeth, but implants can also support multi-tooth restorations. A few strategically placed implants can securely attach a partial or total bridge to the jaw, or provide added support for a removable denture.
Affordability. At first glance, an implant's initial cost places it at the high end of the scale for tooth replacement options. But because of their long-term durability and high success rate (greater than 95% still in place after ten years), implants may cost less in the long run than lower-priced restorations that may require repair or replacement sooner.
Although they have a wide range of applications, implants aren't suited for some dental situations. Because implants require a minimum amount of bone present in the jaw, for example, extensive bone loss might nullify them as a current option. Even in this case, though, grafting therapy to rebuild the bone could make it possible to place dental implants at some point in the future.
If you've recently lost a tooth or you have an older restoration you'd like to replace, dental implants might be a great option for you. Your first step is an initial exam and consultation to find out if this premier dental restoration is right for you.
