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.
While not as prevalent as adults, teenagers can have missing teeth, usually from injury or from never having been formed. Fortunately, life-like dental implants can replace missing teeth. But unfortunately for teens, implants aren't usually a good option—yet.
That's because a teenager's jaws are still growing, and will continue until early adulthood. Dental implants don't adjust to this growth like natural teeth and will eventually look out of place. It's best, then, to consider a temporary restoration for a teenager. And, there are two excellent options: one removable and one fixed.
The first is a removable partial denture (RPD). Like a full denture, an RPD has an acrylic base that resembles gum tissue, to which prosthetic (false) teeth are attached to match the positions of the missing teeth. It's usually held in place with metal or nylon clips that slide under part of the natural teeth at the gum line.
RPDs are versatile and durable. But they're not designed to be worn indefinitely, so they can be damaged if subjected to excessive biting forces like biting into something hard. And, peer-pressured teens may also feel self-consciousness about wearing a “denture.”
The other option is a bonded bridge. It's similar to a traditional bridge, except how it's supported in the mouth. A traditional bridge gains its support from the crowns on each end attached to natural teeth, which must be permanently altered for them. By contrast, a bonded bridge has strips of dental material extending from both sides of its back that are bonded to the back of the adjacent natural teeth.
With the bonding material behind the bridge, it can't be seen—and the natural teeth won't require permanent alteration. But a bonded bridge is usually more costly than an RPD and less secure than a traditional bridge. And not every teen is a viable candidate for one: issues like how the teeth fit together and if the teen has a tooth grinding habit could be strikes against this fixed option.
Your dentist can help you sort out the best of these options for your teen. If cared for and maintained properly, either restoration can buy you time until your teen is ready for dental implants.

Getting a smile upgrade doesn’t necessarily require extensive dental work. You might be able to change your appearance for the better with teeth whitening.
This technique employs a bleaching solution that brightens dull enamel, the outermost layer of teeth. It isn’t a permanent fix, but if cared for properly your brighter smile could last two years or more.
Here’s what you need to know about this proven smile brightener.
Know your options. Enamel whitening is usually obtained in one of three ways: a dentist performing the procedure in-office; at home using custom trays created by a dentist; or at home with an over-the-counter whitening product. The in-office option is the most expensive—but since dentists use a stronger bleaching solution, your brighter tint may last longer and dentists can control the degree of whiteness better.
Know your preferences. That last point is important if you’re looking for a particular look. Teeth whitening can give you a dazzling “Hollywood” smile or one that’s a bit more subtle. It all depends on your lifestyle and personal preferences. Because of their advanced techniques and equipment, you may have better chances getting the look you want from your dentist rather than by doing it yourself.
Know your limitations. This type of teeth whitening won’t work if the staining originates within the teeth—for that you’ll need an invasive procedure only a dentist can perform. You’ll also want to be careful with any whitening if you have dental work like crowns, veneers or fillings: the bleaching solution won’t alter these materials’ color, which could make them stand out beside whitened natural teeth. And if you have diseased teeth and gums, those need to be treated first before any cosmetic procedures like whitening.
Teeth whitening is a great way to take years off a smile. Even if you plan to whiten your teeth at home see your dentist first for a complete examination and helpful tips on products and techniques.

October is National Orthodontic Health Month, and the more than 18,000 members of the American Association of Orthodontists want you to know the importance of a good bite. Correcting a bite problem can do wonders for your health and well-being—and the added benefit of a more attractive smile can do wonders for your self-image and relationships.
Perhaps, though, you’re well past your teenage years and think you might be too old to consider having your teeth straightened. Not at all: Even if you’re a senior adult, you can still undergo bite correction as long as your overall periodontal health is sound.
But then why go through the effort and expense of orthodontic treatment? Here are 3 top reasons why correcting a poor bite is worth it at any age.
Improve digestion. As we chew during eating, our teeth turn food into digestible bits that our body can easily process for nutrients. Misaligned teeth, though, aren’t as efficient at this first step in the digestion process, causing less efficiency at retrieving nutrients along the way. Correcting your bite could therefore improve your digestion and your health.
Prevent dental disease. While you need to brush and floss every day to prevent tooth decay or gum disease, it’s a lot easier if your teeth are properly aligned. Crooked teeth are more prone to collect and harbor disease-causing plaque that can “hide” from brushing and flossing. Correcting your bite can make it easier to remove plaque, thereby decreasing your risk of a tooth-destroying infection and gum disease that can contribute to chronic inflammation in the body.
Renew your confidence. While the previous two therapeutic reasons are primary for orthodontic treatment, don’t discount the power of an improved smile. Gaining a more attractive smile can boost your confidence in social and business situations—which could change your life. Consider it the added “cherry on top” that accompanies better health and wellness when you correct your bite.
If you’re interested in a healthier life and a more attractive smile, see us for a complete orthodontic evaluation. Even if you’re an older adult, you may still be a good candidate for bite correction. And you might not even need to wear braces: depending on your condition, we may be able to correct your bite with clear aligners that are nearly invisible to others while you’re wearing them.
There are good reasons for improving your bite. The sooner you do, the greater the benefits to your health and confidence.

Bite problems aren't limited to teeth simply out of position. The problem could be some teeth aren't there—visibly, that is. They still exist below the gums and bone, but they've been crowded out and blocked from erupting. We call this condition impaction.
Any tooth can become impacted and affect the bite, but a person's smile suffers more if it involves visible front teeth. This is especially so if the teeth in question are upper canines or "eye teeth"—the smile doesn't look normal without these pointed teeth on either side of the central and lateral incisors.
Impacted teeth can also contribute to more than a cosmetic problem: they're more susceptible to abscesses (pockets of infection) or root damage both to themselves or neighboring teeth. To minimize these potential health issues, we'll often remove impacted teeth surgically (as is often done with wisdom teeth).
But because of their important role in not only appearance but also bite function, we may first try to assist impacted canines to fully erupt before considering extraction. It takes a bit of orthodontic "magic," but it can be done.
Before we can make that decision, though, we want to precisely locate the impacted teeth's positions and how it may affect other teeth. This initial evaluation, often with advanced diagnostics like CT scanning or digital x-rays, helps us determine if the impacted teeth are in a workable position to save. If they're not, we may then need to consider removing them and ultimately replacing them with a dental implant or similar restoration.
But if their position is workable and there are no other impediments, we can proceed with helping them erupt. To do this we'll have to first expose them by creating a small opening in the gums through minor surgery. We then bond a small bracket to the tooth, to which we'll attach a small chain that we then attach to orthodontic braces. This enables us to exert continuous pressure on the tooth.
Over time, the pressure coaxes the tooth to erupt. We may still need to apply other forms of orthodontics and cosmetic procedures, but using this procedure to rescue impacted canines can produce a healthier and more attractive smile.
