Dental implants are today’s closest restorative facsimile to natural teeth. And they’re versatile: not only can they replace single teeth but they can also support bridges or dentures.
But since one of their crucial components is made of metal, are you out of luck obtaining this state-of-the-art dental restoration if you have a metal allergy?
The answer is: probably not—it’s rare for implants to cause an allergic reaction. Still, metal allergies can be a potential problem within your mouth as with other areas of health.
An allergy originates from the body’s necessary response to potentially harmful microorganisms or substances. Sometimes, however, this response becomes chronic and exaggerated, creating an allergy. People can have allergies to nearly anything with responses ranging from a minor rash to a potentially life-threatening multi-organ system shutdown (anaphylactic shock).
A small number of people have allergies to particular metals. One of the most common is nickel, which affects an estimated 17% of women and 3% of men; cobalt and chromium are also known to cause allergies. Consumer exposure, particularly metal contact with the skin through jewelry or clothing, is the most prevalent, but not the most concerning. That’s reserved for metal allergies related to medical devices like coronary stents or hip and knee prostheses. And in dentistry, there are rare occasions of inflammation or rashes from metal amalgam fillings.
Which brings us to dental implants: the main metal post that’s inserted into the jawbone is usually made of titanium. It’s the metal of choice for two reasons: it’s bio-compatible, meaning the body normally accepts its presence; and it’s osteophilic, which means bone cells readily grow and adhere to it, a major reason for implant durability.
While it’s possible for someone to have an allergy and subsequent reaction to implants with titanium, the occurrences appear to be extremely low. In one study of 1,500 patients, titanium allergies were estimated to be a factor in implant failures in less than 1% of those studied.
Even so, if you have known metal allergies you should make sure your dentist knows. Being aware of all the facts will help them recommend the best tooth replacement choice for you—and hopefully it will be dental implants.

While some aspects of regular dental visits are much the same for everyone, they can be more involved for an older adult. That’s because people later in life face an increased risk of dental disease and other age-related issues.
If you’re a caregiver for an older adult, you’ll want to be aware of these heightened risks. Here are 4 areas of concern we may check during their next regular dental visit.
Oral cancer. While it can occur at any age, cancer is more prevalent among older adults. Although rarer than other cancers, oral cancer’s survival rate is a dismal 50% after five years. This is because the disease is difficult to detect early or is misidentified as other conditions. To increase the odds of early detection (and better survival chances) we may perform a cancer screening during the visit.
Dental disease. The risks for tooth decay and periodontal (gum) disease also increase with age. A primary risk factor for older people is a lack of adequate saliva (the mouth’s natural disease fighter) often caused by medications or systemic conditions. We’ll watch carefully for any signs of disease, as well as assess their individual risk factors (including medications) for decreased oral health.
Dentures. If they wear dentures, we’ll check the appliance’s fit. While dentures can wear with use, the fit may also grow loose due to continuing bone loss in the jaw, a downside of denture wearing. We’ll make sure they still fit comfortably and aren’t stressing the gums or supporting teeth. It may be necessary to reline them or consider replacing them with a new set.
Oral hygiene. Brushing and flossing are just as important for older adults as for younger people for preventing dental disease, but often more difficult due to mental or physical impairment. We can note areas of bacterial plaque buildup and recommend ways to improve their hygiene efforts.
Depending on how well your older adult can care for themselves, it may be advisable for you to come with them when they visit us. Our dental team can provide valuable information and advice to help you help them have a healthier mouth.

You might think David Copperfield leads a charmed life:Â He can escape from ropes, chains, and prison cells, make a Learjet or a railroad car disappear, and even appear to fly above the stage. But the illustrious illusionist will be the first to admit that making all that magic takes a lot of hard work. And he recently told Dear Doctor magazine that his brilliant smile has benefitted from plenty of behind-the-scenes dental work as well.
“When I was a kid, I had every kind of [treatment]. I had braces, I had headgear, I had rubber bands, and a retainer afterward,” Copperfield said. And then, just when his orthodontic treatment was finally complete, disaster struck. “I was at a mall, running down this concrete alleyway, and there was a little ledge… and I went BOOM!”
Copperfield’s two front teeth were badly injured by the impact. “My front teeth became nice little points,” he said. Yet, although they had lost a great deal of their structure, his dentist was able to restore those damaged teeth in a very natural-looking way. What kind of “magic” did the dentist use?
In Copperfield’s case, the teeth were repaired using crown restorations. Crowns (also called caps) are suitable when a tooth has lost part of its visible structure, but still has healthy roots beneath the gum line. To perform a crown restoration, the first step is to make a precise model of your teeth, often called an impression. This allows a replacement for the visible part of the tooth to be fabricated, and ensures it will fit precisely into your smile. In its exact shape and shade, a well-made crown matches your natural teeth so well that it’s virtually impossible to tell them apart. Subsequently, the crown restoration is permanently attached to the damaged tooth.
There’s a blend of technology and art in making high quality crowns — just as there is in some stage-crafted illusions. But the difference is that the replacement tooth is not just an illusion: It looks, functions and “feels” like your natural teeth… and with proper care it can last for many years to come.Â Besides crowns, there are several other types of tooth restorations that are suitable in different situations. We can recommend the right kind of “magic” for you.

For whatever reason, you’ve put off replacing a missing tooth for awhile. Now you want to fill that empty gap in your smile with a dental implant restoration.
But if your tooth’s been missing for a long time, there could be a problem with space. This is because the teeth on either side of the space may have gradually drifted into it, leaving no room for the implant. You could need orthodontic work first to return these teeth to their proper position.
We could use braces, metal orthodontic devices with wires threaded through brackets bonded to the teeth that are then anchored, usually to back teeth. The orthodontist uses elastics or springs as well as possibly incrementally tightening of the wire against the anchors. These techniques create pressure or tension on the teeth for the desired direction of movement. The teeth’s natural mechanism for movement does the rest.
But while effective, braces can be quite noticeable, an embarrassing thought for many adults having to wear them over several months of treatment. But there may be an alternative: clear aligners, a succession of slightly different plastic trays usually worn in two-week intervals. Sequentially wearing each tray gradually moves the teeth to their desired positions.
Though not appropriate for all bite situations, clear aligners have a number of benefits when they can be used. They’re nearly invisible to others and can be removed for hygiene tasks or rare special occasions. What’s more, the orthodontist may attach a temporary prosthetic (false) tooth to the trays to camouflage the missing space during treatment.
There’s one other issue you may have to deal with: if your tooth loss was related to periodontal (gum) disease, the gums and underlying bone may be in poor condition. In fact, substantial bone loss could rule out an implant altogether. But we may be able to remedy both gum and bone deficiencies through grafting or plastic surgery. It may be possible to regenerate enough bone to support the implant; and surgically repairing your gums will help ensure the implant appears natural.
If you have problems like these, don’t give up on your restoration goal just yet. With some orthodontic and dental work ahead of time, we may still be able to make implants a reality for you.
You’ve suddenly noticed one of your teeth looks and feels uneven, and it may even appear chipped. To make matters worse it’s right in front in the “smile zone” — when you smile, everyone else will notice it too. You want to have it repaired.
So, what will it be — a porcelain veneer or crown? Maybe neither: after examining it, your dentist may recommend another option you might even be able to undergo that very day — and walk out with a restored tooth.
This technique uses dental materials called composite resins. These are blends of materials that can mimic the color and texture of tooth structure while also possessing the necessary strength to endure forces generated by biting and chewing. A good part of that strength comes from the way we’re able to bond the material to both the tooth’s outer enamel and underlying dentin, which together make up the main body of tooth structure. In skilled, artistic hands composite resins can be used effectively in a number of situations to restore a tooth to normal appearance.
While veneers or crowns also produce excellent results in this regard, they require a fair amount of tooth alteration to accommodate them. Your dentist will also need an outside dental laboratory to fabricate them, a procedure that could take several weeks. In contrast, a composite resin restoration usually requires much less tooth preparation and can be performed in the dental office in just one visit.
Composite resins won’t work in every situation — the better approach could in fact be a veneer or crown. But for slight chips or other minor defects, composite resin could transform your tooth’s appearance dramatically.
To see if composite resin is a viable restoration option for your tooth, visit your dentist for a complete dental examination. It’s quite possible you’ll leave with a more attractive tooth and a more confident smile.
