The dental implant is the closest thing in modern dentistry to a natural tooth. This is because an implant replaces more than the visible crown — it also replaces the root, thanks to a metal post imbedded in the bone.
But what if you have a metal allergy — are you out of luck replacing a tooth with an implant? Before answering this question, let's take a closer look at metal allergies.
An allergy is an overreaction of the body's immune system to a particular foreign substance. This response can be as inconsequential as a minor rash or as life-threatening as a shutdown of the body's organ systems. You can be allergic to anything, including metals.
Usually, these allergies are to specific kinds of metals. For example, about 17% of women and 3% of men are allergic to nickel, while smaller percentages are allergic to cobalt or chromium. Most allergic reactions to metal occur from external contact with jewelry or similar metal items that create rashes or other anomalies on the skin. On a more serious note, an allergy to metal in a body replacement part could result in the body rejecting it.
Metals have also played an important role in dental care, particularly dental amalgam used for tooth fillings. Dental amalgam is a mixture of a precious metal like gold or silver with other metals like copper, tin and, in small amounts, mercury. While dental amalgam has been used safely for decades, there have been rare cases of inflammation or rashes.
This brings us to dental implants and the most common metal used in them, titanium. The commercial version of this metal is highly prized in medical and dental applications because it has a special affinity with bone. Bone cells readily grow and adhere to the metal, which strengthens the bond between the implant and the jawbone.
Even if you have a rare allergy to certain metals, it's even rarer that would include titanium. In one particular study of 1,500 implant patients less than 1% reported any reaction at all.
If you're concerned, you can undergo testing to see if you react to titanium. More than likely, though, you'll be able to join the millions of other patients who have successfully restored their smiles with dental implants.

Teeth serve more than a utilitarian function, more than a means to bite or chew food. They're part of our identity and how we express ourselves — especially when we smile. Misaligned, disfigured, discolored or missing teeth diminish our smile and inhibit our confidence in showing it.
We're just now learning how powerful a confident smile can be when interacting with others. And not just on a personal level: your hesitation to smile because of unattractive teeth could impact your career and professional life. That's why cosmetic dentistry has grown in such prominence, and why we're seeing a revolution in new materials and techniques to restore teeth and gums.
Thanks to these advances, we can transform any smile marred by unattractive teeth into a thing of beauty. This transformation can be as simple as whitening for stained teeth or as involved as dental implants to replace missing teeth.
But it's more than creating a change in your appearance that's technically “perfect.” True smile transformation aspires to be more than that: to reflect your individual personality. There are subtleties in any technique for unique self expression. For example, we can create different effects by adjusting the shape of your teeth's edges, like a more rounded “sexy” look or a sharper “sophisticated” one.
We can even go so far as to create a “Hollywood” smile that's perfect and dazzlingly bright. The question is, though, is that the kind of smile you want? You might actually feel more comfortable with a more subdued smile that retains a few “imperfections” you believe distinguish you as an individual.
That's really where the planning process begins: with your desires and expectations. We must then factor in the actual condition of your teeth (as well as bite and gum and bone health) to decide what's realistic and affordable. Out of that will come a smile makeover plan that's truly your own.

Removing plaque, a bacterial film that builds up on teeth, daily is crucial in preventing dental disease, but is your brushing and flossing making enough of a difference?
Plaque forms every day in our mouths as a result of eating. The bacteria in it produce acid, which can erode tooth enamel and cause tooth decay. Certain strains can also infect the gums and cause periodontal (gum) disease. Either of these primary diseases could lead to tooth loss.
Daily plaque removal with brushing and flossing keeps bacteria growth under control, so a quick swish of your toothbrush across your teeth won't be enough. Plaque's soft, sticky consistency enables it to hide in hard to reach places below the gum line, irregular biting surfaces, or in fillings or other dental work.
Because it's virtually invisible, it's hard to tell if you've successfully removed it. That's where disclosing agents can help. These are solutions, swabs or tablets with a dye that temporarily stains plaque while not staining tooth surfaces. Dental hygienists use them to show patients where they're missing plaque when brushing and flossing, but you can also use them at home to see how you're doing between dental visits.
After brushing and flossing, use the disclosure product according to the package directions. If you're using a solution, for example, swish it around in your mouth for about thirty seconds and then spit it out. The dye reacts with leftover plaque to stain it a bright color. Some products even offer a two-tone dye that displays older plaque in a different color from newer plaque.
After noticing the dyed plaque in a mirror, brush and floss until you don't see it anymore. You may have to change your approach, which will help you perform better in the future. Although safe in the mouth, you should still avoid swallowing the agent or getting it on your clothes. Any on your lips, gums or tongue will eventually wear off in a few hours.
A disclosing agent gives you a snapshot of where you need to improve your oral hygiene. Occasional “spot checks” will help keep your brushing and flossing well tuned.
Your teeth naturally wear as you age, but you may be making it worse if you grind your teeth.
Teeth grinding is a behavior that causes the teeth to gnash, grind or clench against each other generating forces greater than those produced from normal biting. These forces often result in tooth wear that cause not only functional problems but result in a more aged appearance. Grinding occurs while a person is awake, but most often episodes occur while asleep at night.
Teeth grinding is quite common in children, but not usually of great concern since most grow out of it. There's even a school of thought that teeth grinding might even help readjust an uneven bite.
Among adults, though, other factors seem to contribute to teeth grinding. Many researchers believe nighttime grinding occurs as a person passes through different sleep phases including deep REM (Rapid Eye Movement) sleep. It may also have a connection with chronic snoring.
Certain medications seem to contribute to teeth grinding, particularly psychoactive drugs like amphetamines. Nicotine falls in this category, which could be why tobacco users report twice the incidence of the habit compared to non-users. Teeth grinding is also connected to another fact of modern life: stress. People who grind their teeth tend to have higher levels of anxiety, hostility or depression.
Because there are multiple triggers, there are many treatment approaches. Whatever course we take, our aim is to eliminate or minimize those factors that contribute to your habit. For example, we can create a custom mouth guard for night wear to prevent the teeth from making solid contact and thus reduce the biting pressure.
Perhaps the most important thing is to control or reduce stress. This is particularly helpful at night to prepare you for restful sleep by changing some of your behaviors. We also encourage investigating other stress therapies like biofeedback, meditation or group therapy.
Whatever the means, bringing teeth grinding under control not only reduces problems now, but could also help prevent abnormal teeth wearing and future health issues down the road.
