With all the new tooth-colored fillings for cavities, it's easy to overlook metal amalgam. While this mainstay of dental care for over a century might not be as attractive as composite resins or glass and resin ionomers, it still has the advantage of strength and durability.
Amalgam is a stable metal alloy usually made up of silver, tin, copper and mercury. The metals are proportioned and mixed precisely to guard against “free” mercury molecules, which could pose a health hazard. The mixture is pliable at first, but then sets hard once molded into the prepared area of the tooth.
Besides strength, amalgam's other advantages include low cost, high resistance to wear and biocompatibility (not toxic to the body or allergy-producing). At the same time, it can require more tooth structure removal to accommodate a filling and cause higher sensitivity to temperature for a while after installation. Its main disadvantage, however, is appearance — it's now considered unacceptable from an aesthetic point of view to use it in visible areas like the front teeth.
Because of this, materials resembling natural tooth color are coming into vogue, especially as their strength improves. Still, dental amalgam continues to play a useful role, especially in less visible back teeth with higher chewing forces.
One past concern about dental amalgam is the inclusion of mercury in the alloy. As mentioned before, mercury is hazardous in a “free” form when not knit microscopically with other metals; as such it can emit a vapor that could enter the bloodstream and damage the nervous system. But after several studies by various organizations, the American Dental Association has concluded amalgam's precise mixture prevents the mercury from taking this form: although some vapor is given off during chewing it's far too low in concentration to pose any danger.
Dental amalgam continues to be an effective choice for fillings. Whether it's the right choice for you will depend on the type and location of a tooth to be filled, and whether durability is a higher concern than appearance. If we do recommend an amalgam filling, you can be assured it's a safe and lasting choice.

The long-running hit show Dancing with the Stars has had its share of memorable moments, including a wedding proposal, a wardrobe malfunction, and lots of sharp dance moves. But just recently, one DWTS contestant had the bad luck of taking an elbow to the mouth on two separate occasions—one of which resulted in some serious dental damage.
Nationally syndicated radio personality Bobby Bones received the accidental blows while practicing with his partner, professional dancer Sharna Burgess. “I got hit really hard,” he said. “There was blood and a tooth. [My partner] was doing what she was supposed to do, and my face was not doing what it was supposed to do.”
Accidents like this can happen at any time—especially when people take part in activities where there’s a risk of dental trauma. Fortunately, dentists have many ways to treat oral injuries and restore damaged teeth. How do we do it?
It all depends on how much of the tooth is missing, whether the damage extends to the soft tissue in the tooth’s pulp, and whether the tooth’s roots are intact. If the roots are broken or seriously damaged, the tooth may need to be extracted (removed). It can then generally be replaced with a dental bridge or a state-of-the-art dental implant.
If the roots are healthy but the pulp is exposed, the tooth may become infected—a painful and potentially serious condition. A root canal is needed. In this procedure, the infected pulp tissue is removed and the “canals” (hollow spaces deep inside the tooth) are disinfected and sealed up. The tooth is then restored: A crown (cap) is generally used to replace the visible part above the gum line. A timely root canal procedure can often save a tooth that would otherwise be lost.
For moderate cracks and chips, dental veneers may be an option. Veneers are wafer-thin shells made of translucent material that go over the front surfaces of teeth. Custom-made from a model of your smile, veneers are securely cemented on to give you a restoration that looks natural and lasts for a long time.
It’s often possible to fix minor chips with dental bonding—and this type of restoration can frequently be done in just one office visit. In this procedure, layers of tooth-colored resin are applied to fill in the parts of the tooth that are missing, and then hardened by a special light. While it may not be as long-lasting as some other restoration methods, bonding is a relatively simple and inexpensive technique that can produce good results.

While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

Like other healthcare providers, your dentist keeps records of your ongoing care. These include not only their written notes but also x-ray imaging, frequency of visits and cleanings, and any medical information that could affect your care. What’s more, they have a legal obligation to maintain these records.
Your dental records help guide decisions about your care. In that regard, you should consider something else—you may need to change providers: your dentist retires or you move; your dentist isn’t in your new insurance network; or, unfortunately, you have an “irreconcilable” difference with your provider.
If that happens, it’s very important your dental records find their way to your new provider. Here are 3 reasons why.
Your individual dental history. Each person’s dental situation and needs are unique. Your past records help clue in your new dentist about your past history and current needs, which will help guide how they treat you.
Time and money. Your dental records contain x-rays or other diagnostic information about your oral condition, including preparations for any upcoming dental work. If you change dentists before completing that treatment, your new dentist may have to start over with new diagnostic tests if they don’t have this previous data. It could cost you more money and make you wait longer for a needed procedure.
Coordinating dental care with your general health. Your mouth isn’t isolated from the rest of your body, and some dental treatment measures could affect other health conditions (and vice-versa). If your new dentist knows other health issues you may have from your previous records, it can help ensure you’re getting dental treatment appropriate to your overall health.
For the most streamlined transition between providers, it’s important your dental records follow you. You’re entitled to having those records transferred, and, if you’re uncomfortable asking yourself, your new provider can obtain them for you. Just be sure to ask.

Eaten in a fast food restaurant lately? If so, maybe you’ve noticed some changes in the big, colorful signs behind the counters. Many have begun promoting a few “healthier” selections (like salads and grilled items) and giving a more extensive listing of nutritional information. But there’s one thing you might not have noticed on those displays: a listing for soda among the beverage choices in the kiddie meal packages. That’s because they are no longer there.
Recently, Burger King quietly removed sugary fountain drinks from the in-store and online menu boards that show what you get with kids’ meals. They were following the lead of McDonalds and Wendy’s, both of which made similar moves in prior months. You can still get a soda with your kiddie burger if you specifically ask for one, but we’re hoping you won’t; here’s why.
For one thing, youth obesity has nearly tripled in the past three decades. As the U.S. Centers for Disease Control and Prevention (CDC) has noted, it’s now an epidemic affecting more than one in six children and adolescents. Many of the extra calories kids get are blamed on sugary drinks: According to a study by the Harvard School of Public Health, children’s daily calorie intake from these beverages rose by 60 percent in recent years. Obesity makes kids more likely to get many diseases, and can lead to problems in psychological and social adjustment.
But that’s not all. As dentists, we’re concerned about the potential for soda to cause tooth decay, which is still the number one chronic disease in children around the world. The association between sugary drinks and cavities is clear. So is the fact that tooth decay causes pain, countless hours of missed school and work, and expense that’s largely unnecessary, because it’s a disease that is almost 100 percent preventable.
While the new signage at fast food restaurants won’t make soda disappear, it does tend to make it less of an automatic choice. Anything that discourages children from routinely consuming soda is bound to help — and let’s point out that the same thing goes for other sweet and acidic beverages including so-called “sports” and “energy” drinks. It’s best to try and eliminate these from your child’s diet; but if you do allow them, at least limit them to mealtimes, and give your mouth a break from sweets between meals. That gives the saliva enough time to do its work as a natural buffer and acid-neutralizer.
What else can you do to help keep your child’s oral hygiene in tip-top shape? Be sure they brush their teeth twice and floss once every day, and bring them in for regular checkups and cleanings. But if you do suspect tooth decay, don’t delay treatment: Left alone, decay bacteria can infect the inner pulp of the tooth, resulting in severe pain, inflammation, and possibly the need for root canal treatment.
