With a 95%-plus success rate, dental implants are an effective and durable replacement for lost teeth. But we can't place them and forget them: if you don't clean and maintain them they could fail as a result of disease.
The inorganic materials that make up the implant aren't in danger of infection. But the living gums and bone that surround and support the implant are at risk. In fact, there's a particular periodontal (gum) disease involving implants called peri-implantitis (“peri” – around; implant “itis” – inflammation).
Peri-implantitis begins when the gum tissues around the implant become infected and inflamed. This happens most commonly because plaque, a thin film of bacteria and food particles, builds up on implant surfaces. Another less frequent cause is a buildup of excess cement used to bond the crown to the implant. We need to remove the built-up plaque or the excess cement during your dental visit.
If the infection isn't treated or you don't keep up effective, daily hygiene practices, the infection can grow and extend deeper into the tissues and finally the bone. This can destroy the all-important integration of bone and metal titanium post that has created the implant's strong hold. When that support becomes compromised the implant can lose its attachment and, if untreated, eventually fail.
It's important to keep an eye out for any indications you may have a gum infection around an implant. Look for redness, swelling, bleeding or pus formation. If the implant feels loose, this may mean that extensive bone loss has already occurred. If you encounter any of these signs, see us immediately for an examination.
The best approach, though, is to prevent peri-implantitis in the first place. So, brush and floss daily around your implant as you do your natural teeth. And be sure you keep up regular dental cleanings and checkups.
With proper care and maintenance you can avoid problems with disease that could affect your implant. Healthy gums and bone will ensure your implant will last for many decades to come.
You've seen ads for “Teeth in One Day” that promise immediate implant placement at the same time you have the problem tooth removed. But this presumes the gums and underlying bone are healthy and able to support and protect the implant. If that's not the case, it may be ill-advised to place an implant on the same day.
Even with immediate placement, there will be a small degree of bone and gum opening or space around the implant after it's placed into the socket. This can often be remedied by placing a bone graft and sometimes a gum graft when we install the implant. It's also possible for natural healing to gradually fill in the space, but we'll need to monitor the site carefully for several weeks.
On the other hand, if we detect significant bone loss (or strongly suspect it will occur), immediate placement may not be an option — there's not enough bone or it's too weak to support an implant. In this case, it's necessary to wait on placement and focus on improving the bone health and quantity, beginning when we remove the old tooth and place a bone graft.
After completing the extraction, we typically place a bone graft in the empty socket. The graft will become a “scaffold” for new bone cells to grow upon. We may then allow about two to four months for new bone to partially replenish the area and then place the implant. The bone will continue to regenerate as it grows and attaches to the titanium implant to create a solid attachment.
If the site, however, still appears fragile even after partial bone growth, we may opt to wait another two to four months before attempting placement. From a long-term perspective, this is the best scenario for ensuring a durable foundation for the implant. It also allows for a socket severely compromised by disease to heal more thoroughly.
To determine which of these placement scenarios is best for you, we'll first need to conduct a thorough dental examination. From there we'll be in a better position to discuss the right implant timeline for your situation. Our main goal is to ensure we can securely place your implant in just the right position to achieve the most successful and attractive result.

With their durability, versatility and life-likeness, there’s no doubt dental implants have revolutionized teeth replacement. If you’re considering dental implants, however, there are some issues that could impact how and when you receive implants, or if you should consider another type of restoration.
Cost. Dental implants are initially more expensive than other tooth restorations, especially for multiple tooth replacement. However, be sure you consider the projected cost over the long-term, not just installation costs. Because of their durability, implants can last decades with little maintenance cost. In the long run, you may actually pay more for dental care with other types of restorations.
Bone health. Dental implants depend on a certain amount of bone to properly situate them for the best crown placement. If you’ve experienced extensive bone loss, however, there may not be enough to support the implant. This can often be overcome with grafting — immediately after extraction, at the time of implantation or a few months before implantation — to encourage bone growth. In some cases, though, bone loss may be so extensive you may need to consider an alternative restoration.
Gum Health. While implants themselves are impervious to infection, they’re supported by gum and bone tissues that can be affected. Infected tissues around an implant could eventually detach and lead to implant failure. If you have periodontal (gum) disease, we must first bring it under control and render your gums infection-free before installing implants. It’s also important to maintain effective oral hygiene and regular dental cleanings and checkups for optimum implant health.
Complications from osteoporosis. People with osteoporosis — in which the bones lose bone density and are more prone to fracture — are often treated with drugs known as bisphosphonates. In less than 1% of cases of long-term use, a patient may develop osteonecrosis in which the bone in the jaw may lose its vitality and die. As with bone loss, this condition could make implant placement difficult or impractical. Most dentists recommend stopping treatment of bisphosphonates for about three months before implant surgery.
If you have any of these issues or other complications with your oral health, be sure to discuss those with us before considering dental implants. With proper planning and care, most of these difficulties can be overcome for a successful outcome.

You may be familiar with a dental implant used to replace a single tooth — but implant technology can do much more. Implants can also support other restorations including total teeth replacement on a jaw.
The reason they're so versatile is because implants replace the tooth root as well as the visible crown. We use a metal post, usually made of titanium, which we surgically implant in the jawbone as a root substitute. Because of a special affinity with titanium, bone around the implant grows and adheres to it and creates a durable bond.
With a single tooth replacement (the implant's original purpose when they were introduced in the 1980s) we attach a life-like porcelain crown to the individual titanium post. But with their continuing development we've adapted implants for other applications, like using a few strategically-placed implants as a stable platform for removable dentures or fixed bridges.
We're now able to use implants to support a full prosthetic (false) dental arch. Though similar in appearance to a removable denture, this particular prosthesis is permanently joined to the supporting implants with retaining screws.
Of course, the application requires careful pre-planning, which includes making sure you have enough healthy bone to support the implants. We'll also need to determine how many implants you'll need (usually four to six for this application) and create a surgical guide to place them in the best location for supporting the prosthesis. A dental technician will then create the prosthesis to match your jaw ridge contours and facial structure.
Using implants this way has a benefit other types of restorations can't provide: they may help stop future bone loss. The jawbone life cycle depends on stimulation from the attached tooth as you bite and chew — stimulation that ends when you lose the tooth. Traditional dentures and other restorations can't replicate that stimulation. Implants, on the other hand, directly encourage bone growth and can stop gradual bone loss.
If you need some form of total teeth replacement, consider one supported by implants. You may find they'll provide an excellent long-term solution to both function and appearance.
The month of May has been designated “Better Speech & Hearing Month” by the American Speech-Language-Hearing Association. Why would this be of interest to dental professionals? Because teeth are vital for good speech, and missing teeth can make it very hard to speak properly.
Speech is all about sounds, and forming sounds correctly requires proper positioning of oral structures such as the lips, tongue and teeth. For example, there are some words that are almost impossible to pronounce correctly without touching your tongue to your teeth. In fact, one of the hardest words to say without teeth…is teeth!
Missing teeth can affect speech indirectly as well, by reducing self-confidence. People who are missing front teeth often develop the habit of talking behind their hand or mumbling to avoid revealing the gap in their smile. Not being able to speak clearly and confidently can affect not only your appearance, but also your job prospects and social life. So what can you do about missing teeth?
Dental implants are today’s preferred tooth-replacement method. Implants are small titanium posts that are inserted in the jaw bone beneath your gums. They serve as “roots” to hold realistic-looking prosthetic (artificial) teeth in place. Implants can be used to replace one tooth, a group of teeth, or an entire row of teeth (upper or lower). Sometimes a dental implant can be placed the same day a failing tooth is removed so that you won’t need a second surgical procedure.
The healthy natural teeth on either side of the gap can also be used to support one or more replacement teeth. This method, called bridgework, can be used to replace a single tooth or several teeth in a row. Another option is removable dentures, which do not stay in the mouth all the time.
Each of these options has its benefits and risks. We’d be happy to discuss all of them in detail and help you decide which would be best in your own situation.
