Installing dental implants involves more than the mechanics of placing them into the jawbone. Ultimate success — a natural and beautiful smile — requires painstaking attention to detail and artistry.
Here are a few of the factors we must consider to achieve a smile with dental implants you’ll be proud to display.
The amount of available bone. For the permanent crown to appear natural, it’s crucial to position the implant precisely. To achieve this precision requires an adequate amount of bone to be present. Unfortunately, bone loss is quite common after tooth loss; to minimize this we place bone grafts in the empty socket if at all possible after extraction to encourage bone growth. It’s also possible in some cases to perform bone grafting surgery before implants to build up bone volume.
Your genetic gum tissue type. There are basically two types of gum tissue people are born with: thin or thick. Thin tissues are more subject to wear, difficult to work with during surgery and can make it difficult to hide the metal components of an implant. Thicker tissues are easier to work with, but can have a tendency to overgrow.
Achieving a natural “emergence profile.” To look natural, the implant crown must appear to seamlessly emerge from the surrounding gum tissue. To achieve this, we must carefully plan and place the implant in the precise location in the bone, taking into account the implant shape and how far it should be placed within the bone to match the position and height of adjacent teeth and gum tissues.
Blending color shades with adjacent natural teeth. When it comes to color, everyone has subtle differences in tooth shades and hues. In fact, there are slight color variations within individual teeth, from the root to the tip of the crown. To make sure the implant blends in with adjacent teeth, it’s important to match the color incorporated into the porcelain crown with the natural crowns beside them.
These and other factors require both technical expertise and a sense of artistry. Carefully considering all of them will help ensure your dental implants result in the smile you want.

You’re considering dental implants and you’ve done your homework: you know they’re considered the best tooth replacements available prized for durability and life-likeness. But you do have one concern — you have a metal allergy and you’re not sure how your body will react to the implant’s titanium and other trace metals.
An allergy is the body’s defensive response against any substance (living or non-living) perceived as a threat. Allergic reactions can range from a mild rash to rare instances of death due to multiple organ system shutdowns.
A person can become allergic to anything, including metals. An estimated 17% of women and 3% of men are allergic to nickel, while 1-3% of the general population to cobalt and chromium. While most allergic reactions occur in contact with consumer products (like jewelry) or metal-based manufacturing, some occur with metal medical devices or prosthetics, including certain cardiac stents and hip or knee replacements.
There are also rare cases of swelling or rashes in reaction to metal fillings, commonly known as dental amalgam. A mix of metals — mainly mercury with traces of silver, copper and tin — dental amalgam has been used for decades with the vast majority of patients experiencing no reactions. Further, amalgam has steadily declined in use in recent years as tooth-colored composite resins have become more popular.
Which brings us to dental implants: the vast majority are made of titanium alloy. Titanium is preferred in implants not only because it’s biocompatible (it “gets along” well with the body’s immune system), but also because it’s osteophilic, having an affinity with living bone tissue that encourages bone growth around and attached to the titanium. Both of these qualities make titanium a rare trigger for allergies even for people with a known metal allergy.
Still, implant allergic reactions do occur, although in only 0.6% of all cases, or six out of a thousand patients. The best course, then, is to let us know about any metal allergies you may have (or other systemic conditions, for that matter) during our initial consultation for implants. Along with that and other information, we'll be better able to advise you on whether implants are right for you.

The term “makeover” is a powerful word in today’s society. It’s used for a variety of things — hair, body, lawn — that need more than a different style, a little toning or some new shrubs. A makeover is a transformation, replacing the dissatisfying status quo with something new and dynamic.
Your smile and its various components — teeth, gums, jaw structure and facial features — might also be a candidate for a makeover. This involves more than just a few modifications. It’s the answer to a smile we avoid showing in photos, cover with our hand when we’re speaking or laughing, or makes us feel older than we really are. In other words, it’s a comprehensive change to a smile that inhibits us from fully expressing ourselves in our friend, family or career relationships.
Of course, for any makeover to succeed, it must follow a plan. A smile transformation is no different. The process begins with what we call a “smile analysis”: a comprehensive examination that determines the exact condition of your entire mouth. This enables us to identify problems and defects, understand how they interact with your other facial features, and then recommend a treatment plan that effectively addresses these issues.
The plan isn’t complete, though, without your input. You may want a complete renovation — to restore missing teeth or change their shape, color and brilliance. On the other hand, you may be more comfortable with a few subtle changes, perhaps even keeping slight imperfections that you see as part of the real “you.” Whichever path you take, the end result is a smile that makes you happy, and proud to show to others.
The various techniques and materials available through cosmetic or restorative dentistry can turn any disappointing smile into a beautiful one. Your journey to that newer, brighter smile begins with your next dental visit.

We're always tickled to see dentists represented in popular culture, especially when portrayed by an actor as handsome as John Stamos. On the hit television show Glee, Stamos played a dentist who made sure the glee club members cleaned up their act when it came to oral hygiene — though perhaps he used a bit too much anesthesia to achieve this admirable goal. While under his care — and lots of sedation — several Glee characters had music-infused hallucinations in which they danced and sang with pop star Britney Spears.
Far-fetched? No doubt. Still, it's worth mentioning that sedation has its place in dentistry. In fact, if you are someone who tends to get anxious or even fearful about dental treatment, you should know that sedation can help you relax both mind and body so you can feel peaceful rather than anxious in the dentist's chair. And that's the whole point: Fear of pain should not stand in the way of your getting the care that will keep you healthy and allow you to keep your teeth for as long as possible.
You may not know this, but when you are afraid, your threshold for pain is actually lower. You become hypersensitive to every sensation and sound, and you tense your muscles. Fear and anxiety trigger the release of certain chemicals that put you in “fight or flight” mode. In this heightened state of alert you experience more pain during and even after treatment.
The good news is that this response can virtually be eliminated with various oral sedatives and/or with nitrous oxide, which is inhaled. Both treatments will allow you to let your guard down and relax. Your apprehension and hypersensitivity to pain will disappear, even though you are still conscious. And when you are relaxed, we are better able to focus on the task at hand, knowing that you are comfortable.
The sedatives used in dentistry have been subjected to rigorous testing and have a strong safety record backed by decades of use. Several even have “amnesic” properties, meaning that you will remember little to nothing of your treatment — unless, of course, you end up singing and dancing with Britney Spears!
