The subject of allergies covers a wide swath in medicine. Among other things, people have allergic reactions to animal fur, various foods and plant pollen. The effects are equally wide-ranging, anything from a mild rash to anaphylaxis, a life-threatening shutdown of the body's vital systems.
Approximately 5% of people are also allergic to various metals including nickel, cobalt, chromium and gold. Reactions to metal can occur when an allergic person comes in contact with items like jewelry, clothing or even mobile phones. There's even a chance of a metal allergy reaction from certain kinds of dental work.
It's unlikely, though, that you should be concerned if you're considering dental treatment or cosmetic work to upgrade your smile. Although allergic reactions like inflammation or a rash have been known to occur with amalgam “silver” fillings, it's quite rare. It's even less of a concern since “tooth-colored” materials for fillings are now outpacing the use of amalgam fillings, which are used in out-of-sight back teeth.
Of course, metal is used for other dental treatments besides fillings, including the most popular of tooth replacement systems, dental implants. An implant is essentially a metal post, usually made of pure titanium or a titanium alloy, which is imbedded into the jawbone. Even so, there's little chance you'll develop an allergic reaction to them.
For one thing, titanium is highly prized in both medical and dental treatments because of its biocompatibility. This means titanium devices like prosthetic joints and implants won't normally disrupt or cause reactions with human tissue. Titanium is also osteophilic: Bone cells readily grow and adhere to titanium surfaces, a major reason for dental implants' long-term durability.
That's not to say titanium allergies don't exist, but their occurrence is very low. One recent study detected a titanium allergy in only 0.6% of 1,500 implant patients who participated.
At worst, you may need to consider a different type of tooth replacement restoration in the rare chance you have a titanium allergy. More than likely, though, you'll be able obtain implants and enjoy the transformation they can bring to your smile.

The top cause for adult tooth loss isn't decay or trauma—it's periodontal (gum) disease. The disease may begin with the gums, but it can ultimately damage underlying bone enough to weaken its support of teeth, causing them to loosen and fall out.
But that's not the end of the havoc gum disease can wreak. The consequences of an uncontrolled infection can ripple beyond the mouth and worsen other health problems like diabetes, heart disease or arthritis.
The common link between gum disease and these other conditions is the inflammatory response, a natural mechanism to fight infection caused by disease or trauma. This mechanism changes blood vessels to increase blood flow to hasten the travel of protective white blood cells to the injury or disease location.
But if this mechanism that supports healing becomes chronic, it can actually do harm. The chronic inflammation that occurs with gum disease can damage mouth structures, just as inflammation from diabetes or arthritis can damage other parts of the body. And any form of chronic inflammation, even that found in gum disease, can worsen other inflammatory diseases.
You can lessen this link between gum disease and other conditions—as well as improve your oral health—by preventing or seeking prompt treatment for any periodontal infection in the following ways:
- Practice daily brushing and flossing to clear away bacterial dental plaque, the main cause of gum disease;
- See your dentist regularly for more thorough dental cleanings and checkups;
- See your dentist promptly if you notice red, swollen or bleeding gums, common signs of a gum infection;
- Stop smoking to lower your risk for both gum disease and tooth decay;
- Adopt a healthy diet, which can help you lose weight (a factor in diabetes and other inflammatory diseases) and strengthen your immune system;
- Manage other inflammatory conditions to lessen their effect on your gum disease risk.
Taking these steps can help you avoid the inflammation caused by gum disease that might also affect the rest your body. Seeking prompt treatment at the first sign of an infection will also minimize the damage to your teeth and gums and the effect it could have on the rest of your health.

As far as your appearance goes, the most important teeth you have are those in the “smile zone.” These are the teeth most visible when you smile—and the ones that awkwardly stand out if they're chipped, worn or otherwise flawed. More than any other teeth, they determine how inviting your smile is to others.
You might think you'll need extensive cosmetic dental work to fix these kinds of dental defects. But that may not be necessary: We may be able to use a dental material known as composite resin to repair the defects in your “smile zone” teeth in one office visit.
Composite resins are a combination of ceramics and plastics that have been around for some time. They've only recently come into wide use, though, with the development of new techniques to bond them to tooth surfaces. They're ideal for chips, cracks, or decayed areas where front teeth make contact with one another. They may also be used occasionally to reshape irregular or misaligned teeth.
You'll first need a complete dental examination to determine if composite resin bonding is an appropriate approach for your situation. If so, we'll begin by preparing the tooth surface to better accept the resin material. We'll then apply the liquid form of the material in layers, along with other agents to increase the material's strength. Each layer is cured (hardened) before applying the next layer.
As the layers build up, we shape the material to achieve a normal tooth appearance. We'll also incorporate your individual color shadings, so that the prepared tooth blends well with surrounding natural teeth. In effect, the procedure requires as much artistry as technical skill to create a natural look.
Though not as strong as porcelain veneers or crowns, composite resins are durable if not subjected to heavy biting forces. And for a few hours in the dentist's chair with minimal tooth preparation, a composite resin treatment can create a dramatic and exciting change in your appearance.
