Dental amalgam—also known as “silver fillings”—has been used for nearly a hundred years to treat cavities. There are several reasons why this mixture of metals has been the go-to material among dentists: Malleable when first applied, dental amalgam sets up into a durable dental filling that can take years of biting forces. What’s more, it’s stable and compatible with living tissue.
But there’s been growing concern in recent years about the safety of dental amalgam, with even some wondering if they should have existing fillings replaced. The reason: liquid mercury.
Mercury makes up a good portion of dental amalgam’s base mixture, to which other metals like silver, tin or copper are added to it in powder form. This forms a putty that can be easily worked into a prepared cavity. And despite the heightened awareness of the metal’s toxicity to humans, it’s still used in dental amalgam.
The reason why is that there are various forms of mercury and not all are toxic. The form making headlines is known as methylmercury, a compound created when mercury from the environment fuses with organic molecules. The compound builds up in the living tissues of animals, particularly large ocean fish, which have accumulated high concentrations passed up through their food chain.
That’s not what’s used in dental amalgam. Dentists instead use a non-toxic, elemental form of mercury that when set up becomes locked within the amalgam and cannot leach out. Based on various studies, treating cavities with it poses no health risks to humans.
This also means there’s no medical reason for having an existing silver fillings removed. Doing so, though, could cause more harm than good because it could further weaken the remaining tooth structure.
The most viable reason for not getting a dental amalgam filling is cosmetic: The metallic appearance of amalgam could detract from your smile. There are newer, more life-like filling options available. Your dentist, though, may still recommend dental amalgam for its strength and compatibility, especially for back teeth. It’s entirely safe to accept this recommendation.
To anyone immersed in the “X-Men Universe” Hugh Jackman will always be Wolverine, a role he played in seven movies. But there’s more to this Australian actor than mutant bone claws and mutton chops that would make Elvis envious. Jackman has also starred in over 20 non-superhero films, including Les Misérables, for which he won a Golden Globe. He is also a Tony award-winning Broadway performer—with a winning smile.
With his famed character Logan/Wolverine fading in the rearview mirror, Jackman has returned to his musical roots. He will play Harold Hill in the Broadway revival of The Music Man, set to open in Fall 2020. And since May 2019 he’s been on world tour with Hugh Jackman: The Man. The Music. The Show., featuring Jackman and a supporting cast performing songs from favorite shows and films, including Les Misérables and the 2017 hit The Greatest Showman.
The Show, with 90 planned stops throughout Europe, North America and Oceania, is a decidedly different “universe” from the X-Men. As Wolverine, Jackman could get away with a scruffier look. But performing as Jean Valjean or the bigger-than-life P.T. Barnum, he has to bring a vastly different look to the role, which brings us to Jackman’s teeth…
Once upon a time, Jackman’s teeth were an unflattering gray—definitely not a good look for stage or film. So with the help of his dentist, Jackman set about upgrading his smile with teeth whitening. Teeth whitening is a great way to take a dull, stained smile and turn up the volume on its brightness—and attractiveness—a notch or two. A dentist applies a bleaching solution that stays in contact with the teeth for a few minutes. The process is often aided by special lighting.
A professional application is especially desirable if, like Jackman, you want “Goldilocks” brightness: not too little, not too much, but just right for you. Dentists can precisely control the tint level to get a brighter but more naturally looking white. Of course, you can also get a dazzling “Hollywood” smile if you so desire.
And although the effect of teeth whitening isn’t permanent, a dental application can last a while, depending on how well you manage foods and beverages that stain teeth. With a touchup now and then, you may be able to keep your brighter smile for years before undergoing the full procedure again.
One important note, though: This technique only works with outer enamel staining. If the discoloration originates from within the tooth, the bleaching agent will have to be placed internally, requiring access to the inside of the tooth. An alternative would be porcelain veneers to mask the discoloration, an option that also works when there is ultra-heavy enamel staining.
If you’re tired of your dull smile, talk with us about putting some pizzazz back into it. Teeth whitening could be your way to get a smile worthy of Broadway.

Bright, naturally white teeth are a key component in a beautiful smile. But the opposite is also true: nothing diminishes an otherwise attractive smile more than stained or discolored teeth.
There is good news, however, about tooth staining: it can be greatly reduced with the right whitening technique. But before taking action we need to first uncover the cause for the staining — whether from the outside or inside of the tooth, or a combination of both.
If it’s an external cause — known as extrinsic staining — our diet is usually the source. Foods and beverages that contain tannins, like red wine, coffee or tea fall in this category, as do foods with pigments called carotenes as found in carrots and oranges. Besides limiting consumption of stain-causing foods and maintaining daily oral hygiene, you can also diminish extrinsic staining with a bleaching application.
There are two basic ways to approach this: with either a professional application at our office or with a home kit purchased at a pharmacy or retail store. Although both types use similar chemicals, the professional application is usually stronger and the whitening effect is obtained quicker and may last longer.
Discoloration can also occur within a tooth, known as intrinsic staining, and for various reasons. It can occur during tooth development, as with childhood overexposure to fluoride or from the antibiotic tetracycline. Poor development of enamel or dentin (the main sources of natural tooth color), tooth decay, root canal treatments or trauma are also common causes of intrinsic discoloration.
There are techniques to reduce the effects of intrinsic staining, such as placing a bleaching agent inside the tooth following a root canal treatment. In some cases, the best approach may be to restore the tooth with a crown or porcelain veneer. The latter choice is a thin layer of dental material that is permanently bonded to the outer, visible portion of the tooth: it’s life-like color and appearance covers the discoloration, effectively renewing the person’s smile.

Sometimes it seems that appearances count for everything—especially in Hollywood. But just recently, Lonnie Chaviz, the 10-year-old actor who plays young Randall on the hit TV show This Is Us, delivered a powerful message about accepting differences in body image. And the whole issue was triggered by negative social media comments about his smile.
Lonnie has a noticeable diastema—that is, a gap between his two front teeth; this condition is commonly seen in children, but is less common in adults. There are plenty of celebrities who aren’t bothered by the excess space between their front teeth, such as Michael Strahan, Lauren Hutton and Vanessa Paradis. However, there are also many people who choose to close the gap for cosmetic or functional reasons.
Unfortunately, Lonnie had been on the receiving end of unkind comments about the appearance of his smile. But instead of getting angry, the young actor posted a thoughtful reply via Instagram video, in which he said: “I could get my gap fixed. Braces can fix this, but like, can you fix your heart, though?”
Lonnie is raising an important point: Making fun of how someone looks shows a terrible lack of compassion. Besides, each person’s smile is uniquely their own, and getting it “fixed” is a matter of personal choice. It’s true that in most circumstances, if the gap between the front teeth doesn’t shrink as you age and you decide you want to close it, orthodontic appliances like braces can do the job. Sometimes, a too-big gap can make it more difficult to eat and to pronounce some words. In other situations, it’s simply a question of aesthetics—some like it; others would prefer to live without it.
There’s a flip side to this issue as well. When teeth need to be replaced, many people opt to have their smile restored just the way it was, rather than in some “ideal” manner. That could mean that their dentures are specially fabricated with a space between the front teeth, or the crowns of their dental implants are spaced farther apart than they normally would be. For these folks, the “imperfection” is so much a part of their unique identity that changing it just seems wrong.
So if you’re satisfied with the way your smile looks, all you need to do is keep up with daily brushing and flossing, and come in for regular checkups and cleanings to keep it healthy and bright. If you’re unsatisfied, ask us how we could help make it better. And if you need tooth replacement, be sure to talk to us about all of your options—teeth that are regular and “Hollywood white;” teeth that are natural-looking, with minor variations in color and spacing; and teeth that look just like the smile you’ve always had.
Because when it comes to your smile, we couldn’t agree more with what Lonnie Chaviz said at the end of his video: “Be who you want to be. Do what you want to do. Do you. Be you. Believe in yourself.”

The reason for extracting a tooth may be all too obvious — the tooth is too decayed or damaged to attempt saving. The reason for extracting a wisdom tooth, on the other hand, may not be so apparent: from the perspective of pain or reduced function, you may not notice a thing. Our recommendation to remove a wisdom tooth is based primarily on what may be occurring out of view below the gum line and its potential threat to adjacent teeth.
Teeth grow and develop below the gum line in the jaw, and then push their way through the gums as they appear in the mouth (eruption). After a normal eruption, the enamel-covered crown is visible above the gum line; the remaining tooth root (about two-thirds of the tooth’s length) resides below the gum line. Because wisdom teeth, or third molars, erupt rather late between ages 17 and 25, they may lack the room to erupt properly due to crowding from other teeth that have already erupted. This can cause the wisdom tooth not to erupt fully through the gums, leaving the crown trapped below the gum line, a condition known as impaction. For the tooth, impaction increases the chances of infection, cyst formation and gum disease around it.
An impacted wisdom tooth can also cause problems for the adjacent teeth as well. The impacted tooth may begin to press against the roots of other teeth; the resulting pressure can damage the other roots, increasing the risk for disease or future tooth loss. A person may not even know they have this problem since there’s often little to no noticeable pain or symptoms.
It may seem counterintuitive, but the best time to remove a wisdom tooth is when it’s not causing immediate problems. There will be, however, signs found during examination (particularly x-rays or CT scan) that future problems are in the making. By extracting an impacted wisdom tooth at the appropriate time, we can avoid more serious problems in the future and improve oral health.
