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.

Mouth injuries in children and teens are more common than you might think: about one out of three boys and one out of four girls will have experienced an injury before they graduate from high school. Besides contact sports, other types of accidents like car crashes or falls are high on the cause list.
Although most dental injuries aren’t considered true emergencies, there are a few where prompt action may mean the difference between ultimately saving or losing a tooth. One such situation is a knocked out tooth.
In the event of a knocked out (or avulsed) tooth, your primary goal is to place the tooth back into the empty socket as quickly as possible. Teeth that have been out of the mouth for less than five minutes have the best chance of reattachment and survival. The first step is to quickly locate the missing tooth.
Once you’ve found it, use only cold, clean water run or poured over the tooth to carefully clean off dirt or debris (no soaps or cleansers). You should also avoid touching the tooth root or scrubbing any part of it. After cleaning it of debris, gently place the tooth back in its socket, then immediately contact us or visit an emergency room. While you’re en route to our office the patient should carefully hold the tooth in place. If the tooth can’t be immediately placed into the socket (the patient is unconscious, for example), then you should place the tooth in a clean container and keep it moist with cold milk, a sterile saline solution or even the patient’s saliva.
Taking these steps increases the chances of a successful re-implantation, although the injury may ultimately affect the tooth’s lifespan. Replanted teeth can suffer from root resorption (where the root tissue dissolves) or a process known as ankylosis in which the tooth fuses directly to the jawbone with no healthy periodontal ligament in between. Either of these conditions can lead to tooth loss.
Still, it’s worthwhile to try to save the tooth, even if for a few more years. Those extra years can help you prepare for a future restoration.

It’s hard to avoid stress in the 21st Century. We’re all bombarded with stressors, from work to family — even our smart phones!
The problem really isn’t the stressors themselves but how we respond to them and try to relieve stress. This can often have a negative effect on our health. One example: bruxism, also known as teeth grinding or clenching.
These habits involve the rhythmic or spasmodic clenching, biting or grinding of the teeth, often involuntarily, beyond normal chewing function. It often occurs while we sleep — jaw soreness the next morning is a telltale sign. While there are other causes, stress is one of the most common for adults, bolstered by diet and lifestyle habits like tobacco or drug use, or excessive caffeine and alcohol.
Teeth grinding’s most serious consequence is the potential for dental problems. While teeth normally wear as we age, grinding or clenching habits can accelerate it. Wearing can become so extensive the enamel erodes, possibly leading to fractures or cracks in the tooth.
When dealing with this type of bruxism, we must address the root cause: your relationship to stress. For example, if you use tobacco, consider quitting the habit — not only for your overall health, but to remove it as a stress stimulant. The same goes for cutting back on your consumption of caffeinated or alcoholic drinks.
Adopt an “unwinding” pattern at night before you sleep to better relax: for example, take a warm bath or keep work items or digital media out of the bedroom.Â Many people also report relaxation or stress-relief techniques like meditation, mindfulness or biofeedback helpful.
There’s another useful tool for easing the effects of nighttime teeth grinding: an occlusal guard. This custom-fitted appliance worn while you sleep prevents teeth from making solid contact with each other when you clench them. This can greatly reduce the adverse effects on your teeth while you’re working on other stress coping techniques.
Teeth grinding or clenching can prove harmful over time. The sooner you address this issue with your dentist or physician, the less likely you’ll experience these unwanted consequences.
