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.

Accidents happen, especially to teenagers involved with sports or similar activities. In an instant they can lose one or more teeth and permanently alter their smile.
Fortunately we can restore a teenager’s lost teeth, but often not immediately as a permanent restoration with a dental implant requires maturity of their jaw structure. Our focus then turns to the age of the patient and the condition of the underlying bone. A future dental implant, your best choice for tooth replacement, depends on bone for support, but also the age of the patient as it relates to jaw development.
There are a couple of ways an accidental tooth loss can harm supporting bone: first and foremost, the impact of the accident itself can damage the bony socket. To find out for sure we may need to perform a cone beam scan, a type of x-ray that allows us to view the area three-dimensionally. If we do find damage, we can attempt to repair the socket through bone grafting.
Bone can also suffer from the long-term absence of a tooth. Bone has a growth cycle in which older cells dissolve and new ones form to take their place. The force generated by teeth when we eat or chew helps stimulate this growth. Without stimulation, as with a missing tooth, the bone may not grow at a healthy rate. In time, it could lose some of its volume and density and not be able to support an implant.
Installing an implant right after tooth loss could help avoid this situation. Bone has a natural affinity with the titanium post imbedded in the jaw and will naturally grow and adhere to it. But we can’t place an implant with a teenager. This is because the jaw is still developing so an implant would gradually become misaligned as the jaw grows. It’s best to install an implant later after full jaw development in early adulthood.
Today, we can place a bone graft in the empty socket right after tooth loss. The graft serves as a scaffold for bone cells to grow on and will help keep the bone volume at a healthy level until we can install an implant.
Timing is everything in restoring a teenager’s accidental tooth loss. But with coordination and care for the supporting bone, a teenager can eventually enter their adult years with their smile intact.

If while watching a Seattle Seahawks game you thought you saw wide receiver D. K. Metcalf sucking on a “binky,” your eyes weren’t deceiving you. Well, sort of not—he’s actually been known to wear a mouth and lip guard shaped like a child’s pacifier.
Metcalf isn’t the only pro football player customizing this essential piece of safety equipment. Broncos running back Ronnie Hillman has been seen sporting “vampire fangs.” And Odell Beckham Jr., wide receiver with the Cleveland Browns, has a series of interchangeable guards with various designs and colors.
You may say, “That’s the NFL, so of course players have the money and fame to dress up their mouthguards with a little flair.” But custom mouthguards aren’t out of reach for the average athlete—in fact, it’s actually a sound idea. Not so much for expressing personality, but for the comfort and protective advantages that a custom mouthguard may have over retail varieties.
Usually made of high-resistant plastic, an athletic mouthguard absorbs blows to the face and mouth during hard contacts in sports like football, basketball and hockey. Mandated by many organized sports associations, mouthguards can prevent dental and facial injuries like chipped or knocked out teeth, gum abrasions or jaw fractures. There’s even some evidence they reduce the risk of concussion.
Many amateur players use what is known as a “boil and bite” mouthguard, available in retail sporting goods stores. They’re softened first, usually in hot water, and then placed in the mouth and clenched between the jaws to obtain a somewhat individualized fit.
Although they do provide some level of protection, a boil and bite mouthguard can’t match the accuracy of a custom mouthguard produced by a dentist based on impressions and measurements of an individual player’s mouth. As a result, custom mouthguards can be made thinner than many boil and bite guards, increasing their comfort while being worn. More importantly, their accurate fit enhances their protective capabilities.
As you might imagine, custom mouthguards are more expensive than their retail counterparts, and with younger athletes whose mouth structures are still growing, it may be necessary to upgrade a custom guard after a few seasons. Still, the cost of a custom mouthguard may be well worth the superior protection it provides for your own little star athlete. And although it may not necessarily look like a binky or vampire fangs, a custom mouthguard could make their playing experience safer and more comfortable.
