Since their introduction over thirty years ago, dental implants have become the most popular choice for dental restoration. Their large variety of shapes and sizes — a far cry from the limited choices of the 1980s — has only served to increase their popularity.
In recent years there's also been an expansion in their applicability. Most people recognize them as replacements for individual teeth — but they can do much more. They're now playing a pivotal role in other dental restorations or situations.
Here are 3 of those “cutting edge” ways implants could change your dental health and smile for the better.
Fixed bridgework. In a traditional bridge, prosthetic (false) teeth use the natural teeth on either side of the empty space for support. In this updated version, implants become the support base for the bridge. For example, a bridge as small as three crowns can be supported by two implants attached to the outside crowns of the bridge. Four to eight implants can support a bridge as large as an entire arch of teeth.
Over-dentures. In cases of significant bone loss, a full or partial denture may be a better option than a fixed bridge. Traditional dentures, though, can contribute to even more bone loss, which can cause the dentures to eventually lose their fit. Implants not only can help stop further bone loss but can also stimulate increased bone density. Two or more standard or mini-sized-sized implants can support a full or partial denture.
Orthodontics anchorage. People with missing teeth aren't the only ones who can benefit from implants. While most bite repairs only require the back teeth to provide anchorage for braces, certain complex bites may need a different point of anchorage. Orthodontists can create a more feasible anchorage point with an implant or a temporary anchorage device (TAD) imbedded in the jaw. This can help isolate teeth that need to be moved from those on the arch that don't.

Allergic reactions aren't necessarily bad: they're your body's responses to possible threats from foreign substances. But the response can go too far and cause a reaction as minor as a skin rash or as life-threatening as a multi-system shutdown called anaphylaxis.
Anything can cause an allergy: animal fur, food, chemicals — or metals. Because metals play such a large role in dental care, it's only natural we're alert to the possibility of allergic reactions from a procedure.
But don't postpone your implants or other dental work just yet — the threat isn't nearly that ominous. Here are a few facts about dental metal allergies to help you sort it out.
Allergic reactions are rare for metals used in medical and dental procedures. Although reactions to metals in joint replacements or coronary stents leading to failure do happen, actual occurrences are rare. Most metal allergies manifest as a skin reaction to jewelry or clothing. It's less likely with medical or dental metals because they're chosen specifically for their compatibility with living tissue.
Amalgam fillings account for most dental work reactions. Dentists have used this multi-metal alloy for fillings and other restorations for well over a century. Tooth-colored resins are now used for most fillings, but amalgam is still used in less visible back teeth. It's very rare for a person to experience a reaction to amalgam, but when it does occur it usually results in minor inflammation or a rash.
Implant titanium isn't just bio-compatible — it's also osteophilic. Titanium is the perfect choice for implants not only because it's tissue friendly, but also because it's bone friendly (osteophilic). Once implanted in the jaw, bone cells naturally grow and adhere to it to create a more durable bond. Not only does the body usually tolerate titanium, it welcomes it with open arms!
While it's still possible for you to have an allergy to implant titanium, the chances are remote. In one recent study involving 1,500 implant patients, titanium allergies occurred in less than 1%. So the chances are high a metal allergy won't stop you from obtaining a smile-transforming restoration with dental implants.

Want to know the exact wrong way to pry open a stubborn lid? Just ask Jimmy Fallon, host of NBC-TV’s popular “Tonight Show.” When the 40-year-old funnyman had trouble opening a tube of scar tissue repair gel with his hands, he decided to try using his teeth.
What happened next wasn’t funny: Attempting to remove the cap, Fallon chipped his front tooth, adding another medical problem to the serious finger injury he suffered a few weeks before (the same wound he was trying to take care of with the gel). If there’s a moral to this story, it might be this: Use the right tool for the job… and that tool isn’t your teeth!
Yet Fallon is hardly alone in his dilemma. According to the American Association of Endodontists, chipped teeth account for the majority of dental injuries. Fortunately, modern dentistry offers a number of great ways to restore damaged teeth.
If the chip is relatively small, it’s often possible to fix it with cosmetic bonding. In this procedure, tough, natural-looking resin is used to fill in the part of the tooth that has been lost. Built up layer by layer, the composite resin is cured with a special light until it’s hard, shiny… and difficult to tell from your natural teeth. Best of all, cosmetic bonding can often be done in one office visit, with little or no discomfort. It can last for up to ten years, so it’s great for kids who may be getting more permanent repairs later.
For larger chips or cracks, veneers or crowns may be suggested. Veneers are wafer-thin porcelain coverings that go over the entire front surface of one or more teeth. They can be used to repair minor to moderate defects, such as chips, discolorations, or spacing irregularities. They can also give you the “Hollywood white” smile you’ve seen on many celebrities.
Veneers are generally custom-made in a lab, and require more than one office visit. Because a small amount of tooth structure must be removed in order to put them in place, veneers are considered an irreversible treatment. But durable and long-lasting veneers are the restorations of choice for many people.
Crowns (also called caps) are used when even more of the tooth structure is missing. They can replace the entire visible part of the tooth, as long as the tooth’s roots remain viable. Crowns, like veneers, are custom-fabricated to match your teeth in size, shape and color; they are generally made in a dental lab and require more than one office visit. However, teeth restored with crowns function well, look natural, and can last for many years.
So what happened to Jimmy Fallon? We aren’t sure which restoration he received… but we do know that he was back on TV the same night, flashing a big smile.

During your lifetime you’ll eat thousands of meals — and generate a lot of force from chewing over the years. But thanks to a support system of gum tissues and bone, your teeth can normally handle it.
What your teeth can’t handle, though, are higher than normal chewing forces on a continual basis. This can happen if you grind your teeth, which can produce 20-30 times the normal force. The habit often arises in adults because of high stress and often occurs during sleep.
These abnormal forces can stretch the periodontal ligaments that hold teeth in place, cause the teeth to become loose and at increased risk for loss. The best treatment strategy is to reduce clenching with, for example, muscle relaxants or anti-inflammatory drugs or lower the effects with a mouth guard that won’t allow the teeth to make solid contact during clenching.
Your teeth can also become loose even with normal chewing forces if you have advanced periodontal (gum) disease. Gum disease arises from dental plaque, a thin film of bacteria and food particles left on teeth due to poor oral hygiene. As it builds up, it causes inflammation of the gum tissues resulting in bone loss and causing the gums to detach from the teeth, increasing pocket depth.
Our first step in this case is to treat the gum disease by removing plaque and calculus (tartar) from all tooth and gum surfaces. This includes infected areas below the gum line and around the roots, a circumstance that could require surgical access.
As treatment progresses in either of these scenarios the gum tissues heal and often regain their attachment to the teeth. But that can take time, so we may need to stabilize any loose teeth in the short term. The most common way is to splint them to other secure teeth. This is done by using a clear acrylic bonding material to join the loose teeth together with a strip of metal or other rigid material (like joining pickets in a fence).
When symptoms arise, quick action is the key to preventing lost teeth. If you notice swollen, painful or bleeding gums or especially loose teeth, don’t delay — contact us so we can begin treatment as soon as possible.
