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. Here’s 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.

Why is it important to replace missing teeth with restorations such as dental implants? You might be surprised to find that the damage caused by missing teeth is much greater than the simple gaps left in your smile.
As the years go by, teeth lost early in adulthood cause structural changes in a person's face. By age 45 changes in facial structure are already visible in the form of sunken cheeks. By 60, cheeks and lips lose their support, resulting in an aging look. This process continues and if the teeth are not replaced, much of the structural support of the person's face is lost.
These changes are caused by loss of bone. Although it may seem static, bone is actually living tissue that needs constant stimulation to maintain its form and density. With normal stimulation it is in a constant state of resorption (breaking down) and deposition (building up). Teeth provide the needed stimulation for the bone that surrounds them (called alveolar bone) as they meet each other during biting, chewing, and speech. When the stimulation continues, the bone continues to rebuild itself. Without this stimulation, the bone resorbs, does not build up again, and loses substance.
Without stimulation, alveolar bone loses width, height, and volume. Since your teeth and their surrounding bone support your chin, cheeks, and lips, this has a powerful effect on your appearance. It may also affect your ability to chew and to speak.
As alveolar bone diminishes, the next layer of bone also begins to resorb. This is the bone of the jaw itself. The lower part of the face begins to collapse, and the cheeks become hollow. This effect is especially noticeable for people with no teeth (edentulous).
Usually the first tooth to be lost, due to infection and decay, is a molar (back tooth). In the past, a missing single back tooth was frequently replaced by a fixed partial denture (FPD). A crown is provided for each of the two teeth on the sides of the gap, called abutment teeth, to support a false tooth in the middle. However, if they are not well cared for, the abutment teeth may be the next to succumb to decay.
Today the treatment of choice is an implant. A dental implant is a tooth-root replacement made of titanium, which fuses with the bone — making it very stable. Above the gums it is covered by a crown that looks like a natural tooth. The benefit of the implant is that it continues to provide stimulation to the alveolar bone, preventing bone loss.
Implants are also a good choice in the case of multiple missing teeth. They can be used to support bridges or false teeth (dentures). The results are an improved, younger appearance and better functionality.

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.

Dental implants are in much demand when it comes to replacing missing teeth. And although they have long-term success rates of well over 95% when properly placed, the dental profession's current rule-of-thumb is to not use them as a treatment option for teenagers because jaw and facial growth are not complete.
As with most things in life, timing can be everything. However, having missing teeth as a teen can contribute to significant loss of self-esteem and psychological issues. All this means is that we must review each patient's needs on a case-by-case basis so that we can determine the optimal time to place implants while maintaining your teen's self-esteem. However, the good news is that there are some temporary tooth replacements available until the timing is right for implants.
Unlike natural teeth, which move and change position along with normal growth and jaw development, implants don't. Because implants replace tooth roots by fusing with the jawbone, their position is fixed. If placed before normal jaw growth and maturity are complete, they appear to sink as the jaws grow and leave them behind!
Given the above details, you can clearly see why it is critical for jaw and facial growth to be complete prior to placing a dental implant. To determine this timeline, we will work with our dental team, which include orthodontists (specialist in the study of the growth, development and moving teeth into the right positions). Working together, we will best be able to assess when the time is right to plan and place dental implants — usually around late teens.
