Lose a baby tooth when you're a young kid, no big deal — you'll grow another. Lose a permanent one and there's cause for concern. For one thing, tooth loss is often a symptom of an underlying oral health problem, such as tooth decay or gum disease, so it's important to identify the cause and treat it to prevent it from progressing. It is equally important to replace the tooth — not simply for the immediate impact it can have on your smile or bite, but for long-term function, esthetics and the health of the bone that supports your teeth.

The primary options for tooth replacement are fixed bridgework and dental implants. Both result in esthetically pleasing outcomes; the main difference is how each is attached. With a bridge, the replacement tooth, referred to as a “pontic,” uses the two natural teeth on either side of the gap — referred to as “abutments” — for support. The pontic is sandwiched between two other crowns, which fit over and are bonded or cemented to the teeth on either side of the gap. To ensure the companion crowns fit properly, the enamel must be removed from each abutment.

Placing dental implants, by contrast, involves working only on the affected area. The “implant” is actually a small titanium rod with spiraling threads just like a miniature screw that is carefully inserted into the jawbone as though it were a natural root. The replacement tooth, a customized crown, is secured to the end portion of the implant by way of an intermediary referred to as an abutment, which firmly anchors it in place.

Both bridges and implants are natural looking, functional, predictable, and reliable. Each has its advantages and disadvantages, and based on your oral health, one may be more appropriate than the other.

While the long-term success rate for a dental implant is well over 95%, there are factors that can compromise their success. For this reason, our office has put together this list so that you can be prepared should you ever need a dental implant. We feel that by providing our patients with this type of easy-to-understand information, we can educate, address any concerns and help produce the best results.

The three most common categories for classifying factors that influence dental implant success are: general health concerns, local factors and maintenance issues. As you may suspect, general health concerns include factors such as:

• Whether or not you smoke or use tobacco products.
• Certain prescription and over-the-counter medications you are currently taking or have recently taken.
• If you have or have a family history of osteoporosis (“osteo” – bone; “porosis” – sponge-like).
• If your medical history includes any cancer or radiation treatment to the jaws.
• Or if you have a compromised immune (resistance) system.

The second category is “local factors” and includes bone quantity and quality — there must be sufficient bone to anchor implants. Other considerations that fall into this category include whether or not you clench or grind your teeth or have additional bite concerns, as all of these can have negative impacts on both the short and long-term success of an implant.

The last category concerns maintenance. While dental implants are superior works of technology that can last a lifetime and produce results that are nearly identical to natural teeth in looks and durability, they do require routine maintenance. This includes daily cleaning (brushing and flossing) and routine visits to our office for evaluation and professional care to make sure they are functioning properly.

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.

1. 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
2. Both bridgework and dental implants can last a lifetime when properly maintained.
   True or False
3. 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
4. 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
5. 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
6. 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
7. Placing a dental implant requires more time when compared to placing a three-unit bridge.
   True or False
8. Both bridgework and dental implants require minor surgery to replace a missing tooth.
   True or False
9. Dental implants are more desirable than bridgework because placing them does not affect the adjacent teeth.
   True or False
10. 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.

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.
