A dental implant as a permanent replacement for a missing tooth can match or even look better than your original tooth. How this happens takes knowledge, skill, experience, and even some art.
Here are some of the factors involved:
- Bone quantity and quality: To look and function like an original tooth, an implant must be supported by an adequate base of (jaw) bone and gum tissue. Bone has a tendency to melt away or resorb after a tooth is lost. Using new bone grafting techniques can help minimize the bone loss that occurs during healing at the extraction site. Bone grafting can also be used to rebuild lost bone at the implant site.
- Adequate bone supporting neighboring teeth: If you lose bone that supports teeth on either side of an implant, the papillae (the little pink triangles of gum tissue between the teeth) may not regenerate after the implant is placed.
- Your inborn tissue type: If your gum tissues are thin and delicate rather than thick and robust, they will be more difficult to work with. To ensure that there is sufficient gum tissue support, (gum) grafting may be necessary.
- Using the temporary crown as a template: A dental implant actually replaces a tooth root. Most dental implants are made of commercially pure titanium, which fuses with the bone in your jaw, making it very stable. The crown, the part of the tooth that is visible above the gum line, is attached to the implant; a customized temporary crown can be fitted to the implant. The temporary crown is a trial for the final crown. It can be used to assess color, shape, the appearance of your smile, and the implantâ??s function in your bite and speech. It gives you the opportunity to decide about design adjustments before the final, permanent crown is placed.
- The skill, experience, and collaboration of your dental team: Each situation is different. The final success of your implant depends on your pre-surgical assessment and diagnosis, as well as how the surgical and restorative phases of treatment are performed. The use of an outstanding dental laboratory is vital to a successful result.

Bacteria are bad… right? They can cause diseases like pneumonia, strep throat, and tooth decay. They are the reason we wash our hands with soap (or antibacterial gels) and cook (or refrigerate) our food. Yet it turns out that bacteria are also necessary to keep our bodies healthy — and new research is showing just how important these tiny microorganisms are to our well-being. Here are five facts you should know about bacteria.
The bacteria in our bodies outnumber our cells by a factor of 10 to 1. An estimated 100 trillion bacteria live inside the average human — but because they’re so small, they make up only 1-3 percent of our body mass.
The collection of bacteria we harbor is called our “microbiome.” Like the groundbreaking study of human DNA called the Human Genome Project, recent research is leading to a “map” of our bacterial makeup. This revolutionary study is called — you guessed it — the Human Microbiome Project.
No two people have exactly the same microbiome. But in general, the bacteria that live in a particular spot on the body (the mouth, for example) play the same roles in different individuals. Research has also shown that a healthy microbiome looks very different from a diseased microbiome.
In terms of bacteria, the mouth is one of the best-understood areas of the body. It has long been known that tooth decay can result when “bad” oral bacteria begin to outnumber their “good” counterparts. Now we are gaining a better understanding of how certain lifestyle factors — like cigarette smoking — may influence the bacterial balance in the mouth.
Understanding the microbiome may lead to new treatments for disease. Researchers hope that one day, certain serious diseases could be controlled by bacterial “transplants” that re-balance an individual’s microbiome. Maintaining a healthy microbiome could also help prevent many diseases.
So by all means, don’t stop brushing your teeth or washing your hands — this helps control bacteria that could harm you — but do remember that not all bacteria are harmful. One day, an infusion of bacteria might just cure your illness.
Each part of the human body is an intricate wonder. Take your teeth, for example: they’re so woven into everyday life we don’t notice them, yet they each work seamlessly with the jaws and mouth so we can eat, speak and even smile.
Here, then, are a few facts to help you understand — and appreciate — these tiny, amazing wonders we call teeth.
Layer Upon Layer. Rather than one solid mass, teeth are composed of different layers of slightly different tissues each with a unique role in protecting and enabling a tooth to function. Innermost is the pulp filled with connective tissue encasing blood vessels and nerves that transmit sensations to the brain. The next layer out is the dentin, a bone-like material sensitive to touch and other stimuli, which also absorbs some of the forces generated when biting or chewing. The outermost layer is enamel, the hardest material in the body and the tooth’s first defense against infection and other dangers.
Front and Center. Teeth perform different functions depending on their type and location. Front teeth are our “onstage performers” — they help us to speak and enunciate words clearly and, of course, contribute to our smile. They’re also adept at cutting through food when it first enters our mouths.
The Support Team. In keeping with our theater analogy, back teeth are our “backstage crew”: they help support our facial height, provide balance for the jaws as we swallow and protect the front teeth from too much vertical force. They’re also able to crush food before we finally swallow, which aids in the digestive process.
Intended for a Lifetime. If you consider all the environmental factors our teeth face — acidic foods, biting forces and temperature swings to name a few — you then can appreciate their resiliency. Of course, teeth have their enemies: decay, infection and trauma. With daily brushing and flossing and at least a couple of visits a year to our office for cleanings and checkups, you can help thwart many of those enemies. With both our efforts we can make sure your teeth really do last a lifetime.
Fluoride has been proven to strengthen tooth enamel against decay. That’s why it’s not only added to toothpaste and other dental products, but also to drinking water — in nearly three-quarters of U.S. water systems.
While research has eased most serious health questions about fluoride, there remains one moderate concern. Too much fluoride over time, especially in infants and young children, could lead to “enamel fluorosis,” an excess of fluoride in the tooth structure that can cause spotting or streaking in the enamel. While often barely noticeable, some cases of fluorosis can produce dark staining and a pitted appearance. Although not a symptom of disease, fluorosis can create a long-term cosmetic concern for the person.
To minimize its occurrence, children under the age of 9 shouldn’t regularly ingest fluoride above of the recommended level of 0.70 ppm (parts per million). In practical terms, you as a parent should monitor two primary sources of fluoride intake: toothpaste and drinking water.
Young children tend to swallow toothpaste rather than spit it out after brushing, which could result in too much fluoride ingestion if the amount is too great. The American Academy of Pediatric Dentistry therefore recommends a small “smear” of toothpaste for children under two, and a pea-sized amount for children up to age six. Brushing should also be limited to no more than two times a day.
Your child or infant could also take in too much fluoride through fluoridated drinking water, especially if you’re using it to mix infant formula. You should first find out the fluoride levels in your local water system by contacting the utility or the health department. If your system is part of the U.S. Centers for Disease Control and Prevention’s (CDC) “My Water’s Fluoride” program, you may be able to access that information on line at http://apps.nccd.cdc.gov/MWF/Index.asp.
If the risk for developing fluorosis in your area is high, you can minimize your infant’s intake with a few recommendations: breastfeed rather than use formula; use “ready-to-feed” formula that doesn’t need mixing and contains lower fluoride levels; and use bottled water specifically labeled “de-ionized,” “purified,” “de-mineralized,” or “distilled.”
Fluoride can be a wonderful adjunct to dental care in reducing risk for tooth decay. Keeping an eye on how much fluoride your child takes in can also minimize the chance of future appearance problems.

Because our main goal is to help you maintain optimal oral health, we use the latest proven technologies, techniques, and treatments to ensure we achieve them. One tool, radiographs or x-ray pictures, has been around for a long time with an inordinate amount of scientific research backing up both its safety and value. Here's a brief summary of why.
X-rays are a form of electromagnetic radiation just like natural daylight, except that they can easily penetrate soft bodily tissues, such as skin and muscles, without causing any harm if used properly. And as you may have guessed, we use them to examine what we can't see with the naked eye. For example, they enable us to see inside tooth structure, bones, and joints of the jaws. This ability makes x-rays a critical tool that we rely upon to monitor your oral health.
How often you need x-rays really depends upon your individual health needs and often is different from family member to family member given their age and oral health. During adolescence, we may need to take x-rays more often, so we can closely monitor the development of the teeth and jaw to check for normal growth and abnormalities, which can be corrected with early diagnosis. We may also need to use x-rays to diagnose trauma if you or any family member has experienced injury or disease. This will enable us to ensure the correct treatment is given and, in fact, is working and that there are no other related concerns.
Today's ultra-sensitive technology uses extremely low dosage x-rays and ensures early diagnosis and monitoring of your oral and dental health in safety and with confidence.
