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.

Q: I’ve heard about dental implants, but I’m still not sure exactly what they are. Can you explain?
A: It’s no wonder you’ve heard of them: Dental implants have been called the most exciting advance in dentistry in the last 50 years! Essentially, the implant itself is a small, screw-shaped post that is placed in the jaw bone (underneath the gums), and serves as a replacement for the tooth’s roots. It is attached to a lifelike crown (a replacement for the visible part of the tooth) via a sturdy connector called an abutment. Dental implants offer results that can last a lifetime, and have the highest documented success rate of any tooth replacement system — over 95%.
Q: How does a dental implant work?
A: A few decades ago, it was discovered that titanium metal has a unique property: It can actually become fused to living bone tissue in a process called osseointegration. Implants are made of titanium, and take advantage of this feature. Solidly anchored in place by both osseointegration and mechanical forces, dental implants provide a strong and durable base for several different kinds of natural-looking and fully functional replacement teeth.
Q: What are dental implants used for?
A: One dental implant can be used to replace just one missing tooth with a crown that matches your own teeth. Two or more dental implants can be used to support a fixed bridge (a series of three or more replacement teeth) without requiring any work to be done on the adjacent, healthy teeth. Four or more implants can support an entire arch (complete top or bottom set) of replacement teeth that won’t slip and will never need to be removed — a great alternative to traditional removable dentures! Implants can also be used to support some kinds of removable dentures, and in certain orthodontic procedures.
Q: What is the procedure for getting a dental implant?
A: The implant process begins with a consultation, a thorough exam, and a set of diagnostic images. Placing one or more implants involves minor surgery, which is typically performed in the dental office and requires only local anesthesia. After the area has been numbed, a small opening is made in the tissue of gums and jaw bone, and the implant is carefully inserted. In some situations, a temporary replacement tooth may be placed on the implant immediately; otherwise, the implant will be allowed to rest for a period of weeks. In either case, the permanent replacement teeth will be secured to the implants at a subsequent visit.
Q: What are the advantages of an implant over other tooth replacement methods?
A: We already mentioned the high success rate and the long life of dental implants. Another advantage is the fact that implants stop the deterioration of bone in the jaw that inevitably follows tooth loss. Bone loss, a “hidden” consequence of tooth loss, is what tends to make people who are missing teeth look older than they really are. Implants need no special care beyond what you would give your natural teeth, and their longevity can make them a cost-effective investment in the long term. Plus, they look, function and “feel” just like your natural teeth.

Everyone knows that George Washington wore false teeth. Quick, now, what were our first President's dentures made of?
Did you say wood? Along with the cherry tree, that's one of the most persistent myths about the father of our country. In fact, Washington had several sets of dentures — made of gold, hippopotamus tusk, and animal teeth, among other things — but none of them were made of wood.
Washington's dental troubles were well documented, and likely caused some discomfort through much of his life. He began losing teeth at the age of 22, and had only one natural tooth remaining when he took office. (He lost that one before finishing his first term.) Portraits painted several years apart show scars on his cheeks and a decreasing distance between his nose and chin, indicating persistent dental problems.
Dentistry has come a long way in the two-and-a-half centuries since Washington began losing his teeth. Yet edentulism — the complete loss of all permanent teeth — remains a major public health issue. Did you know that 26% of U.S. adults between 65 and 74 years of age have no natural teeth remaining?
Tooth loss leads to loss of the underlying bone in the jaw, making a person seem older and more severe-looking (just look at those later portraits of Washington). But the problems associated with lost teeth aren't limited to cosmetic flaws. Individuals lacking teeth sometimes have trouble getting adequate nutrition, and may be at increased risk for systemic health disorders.
Fortunately, modern dentistry offers a number of ways that the problem of tooth loss can be overcome. One of the most common is still — you guessed it — removable dentures. Prosthetic teeth that are well-designed and properly fitted offer an attractive and practical replacement when the natural teeth can't be saved. Working together with you, our office can provide a set of dentures that feel, fit, and function normally — and look great too.
There are also some state-of-the art methods that can make wearing dentures an even better experience. For example, to increase stability and comfort, the whole lower denture can be supported with just two dental implants placed in the lower jaw. This is referred to as an implant supported overdenture. This approach eliminates the need for dental adhesives, and many people find it boosts their confidence as well.

Dental implants are a great choice for many people who need to permanently replace a missing tooth. Reliable and long-lasting, they offer a highly successful outcome, and can even help reduce long-term bone loss and damage to adjacent teeth. One of the best features of implants is that the titanium metal of which they're made actually becomes fused with your natural, living bone tissue.
But sometimes, an examination may show that where you have missing teeth, you may not have enough bone remaining to properly place an implant. Does this mean you're out of luck? Not necessarily!
Employing the refined techniques of bone grafting, regenerating bone tissue has become a standard procedure in periodontal and oral surgery. In many cases, it's possible to build up just the right amount of bone using a variety of grafting materials, in combination with other special techniques. This can enable patients who wouldn't otherwise be good candidates to enjoy the benefits of dental implants.
How does it work? Basically, by helping your body repair itself.
You may already know that bone is a living tissue, which can respond to its environment positively (by growing) or negatively (by resorbing or shrinking). When you've lost bone tissue, the trick is to get your body to grow more exactly where you want it. Once we know where — and how much — replacement bone is needed, we can place the proper amount of bone grafting material in that location. Then, in most cases, the body will use that material as a scaffold to regenerate its own bone.
Bone grafting is often done at the time of tooth removal as a preventive procedure or prior to the placement of an implant, to give the body time to re-grow enough of its own tissue. The procedure is generally carried out under local anesthesia, or with the aid of conscious sedation. Sometimes, if there is enough natural bone to stabilize it, it's even possible to place an implant and perform a bone graft at the same time.
So if you're considering dental implants, let us advise you on what's best for your particular situation. We have the knowledge and experience to help you make the right choices, and achieve the most successful outcome.

The lengths that some comedians will go to for a laugh! Actor Ed Helms, as dentist Stu Price, pulled out his own tooth in the movie The Hangover. Or did he? Turns out Helms really is missing a tooth, which never grew in. When he was in his late teens, he received a dental implant to make his smile look completely natural.
Helms told People magazine he wasn't exactly eager to remove the implant crown that had served him so well for almost 20 years, but there was no better way to do the famous tooth-pulling scene.
“We started to do different tests with prosthetics and blacking it out and nothing worked,” Helms told the magazine. Helms' dentist said it would be okay to take the implant crown out. “My dentist was really into it,” Helms said. The rest is movie history!
Congenitally missing (“con” – together with; “genital” – relating to birth) teeth are inherited and actually quite common. More than 20% of people lack one or more wisdom teeth, for example. These would not usually be replaced if missing (in fact, wisdom teeth are often removed) but it's a more serious issue when the missing tooth is in the front of the mouth — and not just for aesthetic reasons.
When a particular type of tooth is missing, it disrupts the pattern and function of the teeth. If left alone, sometimes the existing teeth will shift to close the gap. It's like removing a brick from an arch — the rest of the bricks would fall together in a different formation (or collapse entirely). And when upper and lower teeth don't come together properly, they can't function well.
The best treatment for this type of situation is the one Ed Helms had: a dental implant. They look and function like real teeth and do not attach to or damage adjacent teeth as other tooth-replacement options might.
It is important that a child with a congenitally missing tooth wait until jaw growth is complete — different for every person but usually in the late teens — before getting an implant. Otherwise, the artificial tooth might eventually appear too short when the person has stopped growing. In the meantime, there are temporary tooth replacements that can be made.
