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.

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.
Losing your teeth can be a traumatic experience with serious consequences for your overall health. Fortunately, you have great options for replacing lost teeth that can restore both appearance and dental function.
One such option is a fixed bridge supported by dental implants. While implants are best known for single tooth replacement, they can also be used with other restorations like bridges. In this case, the bridge is screwed into a few well-placed implants to support it.
Implants can provide bridges with more security and support, and without the need to alter adjacent teeth that are commonly used for traditional tooth replacement. They may also slow or stop bone loss because the titanium in implants naturally attracts bone cells that grow and adhere to its surface and provide stimulation to the bone cells during function.
Because of these benefits an implant-supported bridge could be a life-changer that provides years of satisfaction. But we can’t simply “set them and forget them”: They require dedicated oral hygiene just like natural teeth.
While the bridge materials and implants themselves are in no danger from disease, the same can’t be said for the implant’s supporting gums and bone. Dental plaque, the main driver in gum disease, can place these tissues at risk for infection that could eventually lead to implant failure.
It’s important, then, for you to floss around your new implants to remove any plaque. This differs from regular flossing in which you work the thread between teeth. Instead, you’ll have to maneuver the floss between the bridge and gums with the help of a floss threader, a small slender tool with a loop at one end and a stiffer plastic edge at the other (similar to a sewing needle).
To use it, first run 18” of floss through the loop until you get equal lengths and then work the tail of the floss threader between the bridge and gums while holding one end of the floss. Once through, you pull the floss threader through so that the floss is on either side of the bridge. Then grab each end of the floss and pull it snug to floss up and down one side of the implant. Go to the next side and repeat this procedure for all the implants.
As an alternative, you could use an oral irrigator, which emits a pulsating spray of water to loosen and wash away plaque. Either way, though, it’s important to floss around implants to get the most life out of your bridge.

Dental implants aren't simply prosthetic teeth, but rather an innovative system that restores both smile appearance and dental function. And while an implant can indeed replace a single tooth, they can do so much more. Integrated with removable dentures or a fixed bridge, they provide a secure solution to multiple missing teeth.
Implants essentially replace a missing tooth's root, the basis for their lifelikeness and functionality. As such, they're also the most sophisticated restoration used today, requiring a high degree of technical and aesthetic skill to place them properly. In reality, implantation is more a process than a procedure.
If you're considering implants, that process begins with a comprehensive dental exam. During the exam, we'll assess the exact condition of your oral and facial structures like the length of remaining teeth, your bite and jaw dimensions. We'll use this information to plan the type and placement of your implants. The exam may also reveal problems like bone loss that might postpone your implants or suggest another form of restoration.
Using digital technology, we then locate the exact positions for your implants on the jaw to ensure the best outcome. This often results in the creation of a surgical guide, a plastic template placed over the jaw that accurately pinpoints the locations for the drilling sequence during implant surgery.
In most cases once the implants are surgically installed, gum tissue may be sutured over the implant to protect it while it integrates with the bone. In some cases, though, a visible crown may be placed immediately, so the patient can enjoy a tooth-filled smile the same day. This immediate crown, though, is temporary and will be replaced with a more durable, permanent one in a few months.
During this interim, the titanium in the implant post will attract bone cell growth, which will build up on the implant surface. This increased bone contact will help secure the implant fully in the jaw, giving the implant its signature durability.
Once the integration is complete, the permanent crown is affixed to the implant (or implants in the case of a fixed or removable dental appliance). It may have been a long road, but you'll have the closest thing to real teeth.

When you hear the word “surgery,” your first thought might be of a high-charged operating room with a surgeon operating intently as a nurse mops sweat from their brow. While there are high-stakes surgeries, most aren’t quite that dramatic.
Dental implant surgery falls into the latter category. It does qualify as a surgical procedure because we make incisions and tissue alterations for the implant. But it’s no more rigorous than a surgical tooth extraction.
Still, if you’re new to implant surgery, it’s natural to feel some apprehension about it. To calm any nervousness, here’s a rundown of what to expect before, during and after the procedure.
Pre-Planning. Implant surgery is usually a routine affair because of meticulous planning beforehand. Often, we map out the implant site using CT scanners or other high-level imaging, identifying obstacles like nerves, blood vessels and sinus cavities, verifying there’s enough bone present to support an implant. With this information we can create a surgical plan or guide for placement in the mouth to accurately situate the implant.
Site Prep. On the day of the surgery we’ll first administer local anesthesia to numb the entire work area to pain. We’ll start with a few small gum incisions to expose the bone. Then using the surgical plan or guide, we’ll create a small channel for the implant with a drilling sequence that successively enlarges it until we achieve the best fit for the implant.
Implant Placement. Once we’ve completed drilling the channel, we’ll remove the implant from its sterile packaging and install it in the channel. After we’ve made any necessary adjustments and verified proper placement with x-rays, we’ll suture the gum tissue back into place.
After the Surgery. You might experience mild to moderate discomfort afterward that’s usually manageable with over-the-counter pain relievers like ibuprofen or acetaminophen. We can, if necessary, prescribe medication if you require something stronger. We may also prescribe an anti-bacterial mouth rinse for a short time to reduce the risk of infection.
After the implant has integrated with the bone which usually takes about 8-12 weeks, we’ll install your life-like crown or restoration. Your new smile and improved dental function will be well worth the process.
