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.
Miley Cyrus's rise to fame began when she was cast in the Disney series Hannah Montana. She played the title character, Hannah Montana, a famous singing star hiding her true identity, ordinary girl, Miley Stewart. In her real life at the time, Miley Cyrus had her own little secret—she was undergoing orthodontic treatment to straighten her smile.
Like many teenagers (as well as many adults), Cyrus's dental bite wasn't in proper alignment. She could have gone the traditional way by straightening her smile with braces fixed to the front of her teeth. It's an effective treatment, but the metallic hardware can overwhelm a person's appearance.
With her various roles in the public spotlight, Cyrus and her family wanted an effective but out-of-sight method for moving her teeth. They chose a relatively new one called lingual braces. Unlike traditional braces, the hardware for lingual braces is fixed on the back of the teeth (or the tongue side, hence the term “lingual”).
Lingual braces can correct any bite problem labial (“lip”) braces can, just through different mechanics of movement. Its main appeal is that the hardware is hidden behind the teeth, so only you and your orthodontist need know you're wearing braces.
There is also less risk of damage to the mouth or the braces themselves if you're in a sport or profession where you're at high risk for facial blows. And unlike patients with traditional braces, you'll have an unobstructed view of your progress over the course of treatment.
Lingual braces do tend to cost more than traditional braces. Some patients also have difficulty at first with speaking and tongue comfort, though most grow accustomed to the braces within a couple of weeks. Because lingual braces are relatively new, there's been a limited number of orthodontists offering it.
But lingual braces are just one of the ways to straighten teeth. Modern dentistry offers several ways to give you your dream smile. If you have dental problems or would like to improve the look of your smile, please contact us or schedule a consultation, and we can discuss your options.

Getting a new smile doesn’t have to be an elaborate affair. If your teeth have minor to moderate chips, stains or tooth gaps, dental veneers could be the answer. These thin wafers of dental porcelain mask tooth imperfections and completely change your smile’s dynamic—and without a huge impact to your wallet.
To achieve that effect, though, your personal set of veneers will require the expertise of both your dentist and a dental lab technician to design and create your veneers. And while there are numerous considerations in achieving a truly life-like appearance with veneers, one of the most important is their color.
We always associate the color white with teeth. And while it is the dominant hue, actual tooth color is more complex. An individual tooth is comprised of multiple shades and tints, that range in variation from its biting edge to the gums. Likewise, tooth color in general can differ from person to person.
Your dentist must take these individual color variations into account while designing your new veneers, especially if you’ll be getting them for some but not for all your teeth. In that case, it’s important for the veneer color to blend seamlessly with the color of your natural teeth without veneers.
Your new smile expectations and desires are also important and should be considered when designing veneer coloring. For instance, do you want a more natural look—or would you prefer a smile with more “dazzle”? This could have an impact on color.
Your dentist takes all of this information (including your input) and communicates it clearly to the dental lab technician creating the veneers. That process is a combination of both science and artistry, using a variety of techniques to achieve an accurate, life-like texture and color result. For example, a technician may paint the edges of the veneers with a ceramic paste that when cured produces a life-like translucency.
This meticulous attention to color detail is necessary to create beautiful veneers that look natural. If the color is right, you’re sure to enjoy the change your veneers bring to your smile for many years to come.

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.

You feel great about your new smile, thanks to dental implants! And you may also be feeling relief as the problems with your former teeth fade into the past.
But that doesn’t mean you can drop your guard on periodontal (gum) disease. Even though implants are impervious to decay, the natural tissues supporting them are vulnerable to periodontal (gum) disease. If they become diseased, your implants could lose their bone support and eventually fail.
And that failure could happen quickly. That’s because, as life-like as they are, implants don’t have one important advantage of real teeth: an attachment to a connective tissue called the periodontal ligament. This tough but elastic ligament lies between the teeth and the bone, attaching to both with tiny extending fibers and holding the teeth in place.
And that’s not all: Because the periodontal ligament contains an abundance of blood vessels, it can supply antibodies to help fight infection. The body’s defenses may not be able to stop disease, but they can certainly inhibit its progress.
Implants can’t benefit from this infection-fighting mechanism. So, when an infection arises in the gums surrounding an implant, it can spread rapidly through a form of gum disease known as peri-implantitis (literally “inflammation around an implant”). If we don’t stop it with prompt treatment, you could lose bone support from your implant and eventually lose it, sometimes in quick fashion.
That’s why you should clean your implants everyday like you do the rest of your teeth with brushing and flossing. You should also visit us regularly for dental cleanings. A dental cleaning involving implants is similar to one with natural teeth, except the hygienist won’t use metal instruments on the implants—this could create tiny scratches on their surface. Instead, they’ll use nylon or plastic instruments or ultrasonic equipment to clean them.
You should also make a dental appointment as soon as you notice swollen, reddened or bleeding gums. If you have gum disease, we can stop the infection through treatment and restore your gums to health. This can be a long and involved process, but it’s necessary to preserve your implants.
It’s true that implants can change your life. If you want to enjoy that change for a long time, take care of your implants and the natural tissues that support them.
