If you've recently had a dental implant placed, congratulations! You have made a good investment in your smile that should last for a lifetime — if you take proper care of it. This is easy to do with a good oral hygiene routine and regular professional cleanings. Here are some important things to keep in mind about implant care:
- Implants can last as long as teeth. A dental implant made of titanium will fuse to the bone surrounding it and function just like a natural tooth. It is a highly successful method of tooth replacement that succeeds more than 95% of the time.
- Implants and natural teeth attach to surrounding bone and gums very differently. A natural tooth does not actually fuse to the bone that surrounds it. Instead, it is held in place by a periodontal ligament (“peri” – around; “odont” – tooth) made up of tiny fibers that insert into the bone on one side and into the tooth on the other. Farther up, these collagen fibers attach the tooth to the gum tissue. Implants and the crowns that go on top of them are not anchored to the gum in this way. An understanding of this biology is important for maintaining good periodontal health when implants are present. We will go over this with you so can care for your implants correctly.
- Infection is the enemy. Bacterial infection is a concern with both natural teeth and implant-supported teeth. A bacterial biofilm (plaque) builds up daily on implant teeth, just as it does on natural teeth. If it is not regularly cleared away, various oral infections can develop. In the case of natural teeth, this might result in tooth decay, gum disease, and the loss of tooth-supporting bone. Implants can't decay, but they can be threatened by a rapidly progressing infection known as peri-implantits (“peri” – around; implant “itis” – inflammation), which can lead to a well-like or dish-shaped loss of bone around the implant. The implant can become loose as greater amounts of bone is lost.
- Good oral hygiene is as important as ever. Daily removal of bacterial biofilm is key to preventing peri-implantitis. You'll want to make sure you brush your teeth twice daily with a soft brush and fluoride toothpaste, and floss gently at least once per day.
- Your dental hygienist has an important role to play. Professional cleanings here at our dental office are also still as necessary as ever, if not more so. Dental hygienists have special instruments they use to clean areas around your implant that can't be reached by your brush or floss — without scratching the surfaces of your implant components.
What does the term “two-implant overdentures” mean?
For more than a century, complete dentures were the only care option for edentulous (toothless) people. As a solution, these left a lot to be desired, particularly for the lower jaw. Now dental technology has developed a better alternative that combines two strategically placed dental implants and a traditional lower denture that has been modified to fit over the two implants — thus the term.
What are the problems with traditional dentures?
The problem is that when you lose teeth, the bone that supported the missing teeth begins to shrink away. This is known as resorption, and it is the reason that dentures fitted too soon after teeth are lost quickly become loose. Bone loss happens most rapidly during the first year and is four times greater in the lower jaw than in the upper.
Why not just use dental adhesives to hold dentures tightly to the lower jaw?
Zinc, a major ingredient in most dental adhesives, has been associated with neurological disorders and may be unsafe. In addition, dental adhesives are expensive and the cost of frequent usage adds up.
Besides dental adhesives, are other health problems associated with dentures?
Yes, edentulism has been related to poor nutrition. Many edentulous people switch to soft foods with high fat content because they find healthier foods like vegetables and proteins difficult to chew.
What are dental implants?
Dental implants are replacements for the roots of teeth, the parts that are below the gumline and anchored in bone. They are usually covered with a crown that shows above the line of the gums.
What are the benefits of implants?
Most importantly, implants reduce the amount of bone resorption. Studies have shown about 75% less resorption in parts of the jaw with implants compared to areas without them. Since most of the bone loss occurs within the first year after tooth loss, it is important to place implants within this time period.
Is a complete set of dental implants a good solution for edentulism?
Yes, it can be a good solution, but it is not for everyone. Some patients, who have lost a great deal of bone support, need another solution for cosmetic reasons that offer more facial support like an implant overdenture. In addition, depending on their resources and insurance, some people require a less expensive solution.
Why does the two-implant overdenture work better for the lower jaw?
Based on differences in bone volume, density and other factors, we think that four to six implants are needed to retain an upper implant overdenture. Thus a two-implant overdenture is a good solution to consider for a lower jaw, but other options might be preferred for an upper jaw.

Of all the of amazing procedures in today's dentistry, surgery that causes new bone to grow — in places where it had previously been lost — is high on the list of the most extraordinary. (When bone is lost or resorbed, it is broken down into its mineral components, which are dissolved into the bloodstream. Resorption of tooth-supporting bone often takes place after teeth are lost.) Dental techniques that cause new bone growth are important because a certain amount of bone is needed to replace lost teeth with dental implants.
Today's dental implants themselves are an amazing innovation. Implants consist of a replacement for the tooth's root, usually made of a metal called titanium. A replacement for the crown, the part of the tooth that is visible above the gums, is attached to the titanium root. Titanium has the remarkable quality of being able to fuse with the bone in which it is anchored. This process, first discovered in the 1950s, is called osseointegration.
In the case of missing upper back teeth, many people who wanted dental implants in the past were told that they did not have enough bone to anchor the implants and that they had to get removable dentures instead.
But now a new surgery called maxillary sinus augmentation can cause your body to regenerate bone where it was lost and is needed to anchor dental implants.
Bone in the upper jaw or maxilla usually supports your upper back teeth. Inside the maxilla, on either side of your upper jaw, are air spaces in the bone, which are lined with a membrane. These spaces, called the maxillary sinuses, are generally shaped like pyramids; but their shape and size is different in each person. The new surgical procedures involve lifting up the sinus membrane in the area where bone is needed and filling the space thus created with a bone grafting material. Your body then creates new bone to fill the space. This usually takes about six months. If you have almost enough bone to stabilize the implants, they can be placed simultaneously with the graft, thus saving time and avoiding a second surgical procedure.
All grafting materials used today are approved by the Food and Drug Administration (FDA) and must be prepared according to their guidelines. They are specially treated to render them completely safe for human use.
After the surgery there is usually no more than mild to moderate swelling and some discomfort, about the same as having a tooth removed.

Dentists often recommend bone grafting to ensure the success of dental implants. And it is likewise common for people to squirm a bit at the thought. Bone graft? That sounds serious. And maybe a bit, well, unappealing. These feelings are completely understandable. After all, this may be something you've never had to consider before. But there's no reason to worry. Hereâs why:
- Bone grafting is not new or experimental. It is actually a very routine part of the implant process, as well as other types of oral and periodontal surgery. And it is very successful when performed by an experienced doctor.
- Bone grafting materials are processed for safety. The grafts used — whether synthetic or from a natural source, such as cow or human bone — have been specially treated for medical use.
- Only a small amount of this bone-grafting material is needed. Once placed in the site of the missing tooth, it serves as a helpful scaffold your body uses to build more of its own bone in that spot.
- Your implant will be more ideally positioned and may work better. It needs a good, strong foundation with which to fuse. But when teeth are lost, this supporting bone is often lost, too. This loss is often unpredictable and bone grafting limits the change that occurs. In fact that's one of the main benefits of replacing missing teeth with implants: they help prevent bone loss just as a natural tooth does.
- Your implant will look so much better! Think about it: Your original tooth was supported to a certain height by the underlying bone. If that bone is now gone, the replacement tooth is going to be much longer because of the missing bone height. It may not look quite right without that additional support.
So if you want the best-looking and best-functioning implant possible, have no fear of bone grafting. And please contact us to discuss any of your concerns, or schedule an appointment for an implant consultation.

Most people think of bone as rock-solid, but it's actually a living tissue that's constantly changing. This has significant implications for your oral health, general health, and appearance — if you are one of the 70% of Americans missing at least one tooth.
Throughout the day, your top and bottom teeth make hundreds of fleeting contacts with each other. These small stresses are transmitted though the periodontal ligament (“peri” – around; “odont” – tooth) that supports each tooth in its socket like a hammock. Think of it as a gentle push on the hammock, which causes the tooth to gently bump the underlying bone. The bone then builds up in the spot that's receiving stress to counteract it. This constant remodeling of bone is what allows bone to stay healthy and strong.
When a tooth is lost, the bone does not receive that gentle stress. It reacts by literally melting away. Sometimes this happens fairly quickly — in a matter of months. After the tooth-supporting bone is lost, the jawbone itself begins the same process of deterioration. This could eventually change the shape of the face, as the distance from nose to chin can decrease — even if only a few back teeth are missing. The results aren't pretty. But the good news is, there's a way to prevent all this.
Dental implants, which function as substitute tooth roots, actually save underlying bone when teeth are lost. They do this because they are made of titanium, which fuses to the bone in which it's set, stabilizing it. The implant is topped by a realistic-looking crown, which replaces the part of the missing tooth that was visible in the mouth. Together, they look and function just as your natural tooth did.
If you are missing a lot of teeth, implants can also be used to anchor bridges or even removable dentures while providing that same bone-saving benefit. And when you consider that they are so durable they should never need replacement, implants are a great investment.

Fracturing back molars is an experience no one ever wants to have. But when a helicopter crashed during a back country ski trip, supermodel Christie Brinkley soon discovered that she had fractured two molars. Fortunately for Christie, her oral health was restored with two dental implants. As she said during an interview with Dear Doctor magazine, “I am grateful for the dental implant technology that feels and looks so natural.”
While Christie's dental implants replaced back teeth, we routinely use them to replace both back and the more visible front teeth. But best of all, we have demonstrated expertise at making dental implant crowns look real. This is where we meld science and artistry.
What drives the most natural and beautiful result is how the crown (the visible, white portion of a tooth) actually emerges through the gum tissues. We also match the adjacent teeth identically in color, appearance, shape and profile. But we can't take all the credit, as it takes an entire “behind-the-scenes” team to produce dazzling results. Choice of materials, the laboratory technician (the person who actually handcrafts the tooth), the expertise we use in placing a dental implant crown and the total quality of care we provide are the ingredients necessary for success.
Another critical factor required is ensuring there is enough bone volume and gum tissue to support an implant. Both of these must also be in the right position to anchor an implant. However, if you do not have adequate bone volume, you may be a candidate for a minor surgical procedure to increase your bone volume through bone grafting or other regenerative surgical techniques.

When it comes to replacing missing teeth, we have numerous options. However, two of the most common treatment options include bridgework and dental implants. See how much you really know about dental implants and bridgework by taking our quick and easy true/false self test.
- When it comes to costs, dental implants may initially cost more than bridgework but are less expensive than bridgework over a lifetime.
True or False
- Both bridgework and dental implants can last a lifetime when properly maintained.
True or False
- Prior to placing a three-unit fixed bridge, if the surrounding teeth have crowns, they must be redone so that the bridge fits and wears properly.
True or False
- Replacing a single tooth with a three-unit bridge, requires removing the enamel on the adjacent teeth even if these teeth are disease-free.
True or False
- In addition to being permanent tooth replacements, another advantage of dental implants is that they don't decay like teeth supporting bridgework.
True or False
- It is not uncommon for root canal treatment to be required to save teeth that support bridgework if they have been subjected to severe decay and their nerves become infected.
True or False
- Placing a dental implant requires more time when compared to placing a three-unit bridge.
True or False
- Both bridgework and dental implants require minor surgery to replace a missing tooth.
True or False
- Dental implants are more desirable than bridgework because placing them does not affect the adjacent teeth.
True or False
- Studies indicate that bridges are only 67% successful at 15 years whereas dental implants have success rates into the 90s.
True or False
Answers: 1) True. This fact shocks many people. 2) False. This is more commonly true for dental implants. 3) True. 4) True. This is one of the disadvantages of bridgework. 5) True. This is just one of the advantages of a dental implant. 6) True. 7) True. 8) False. Dental implants require surgery to be placed. 9) True. This fact is a significant advantage for dental implants. 10) True. Your results may vary; however, this statistic represents what you might expect.
