One of the top concerns in public health today is exposure to the metallic element mercury within the environment. At abnormal levels, mercury can have a toxic effect on our nervous systems and cause other health problems.
These concerns over mercury have also increased attention on one material in dentistry that has included the metal in its makeup for over a century — dental amalgam for filling teeth. Amalgam is a metal alloy that can include, in addition to mercury, silver, tin, and copper. When first mixed dental amalgam is a moldable material used for fillings in prepared teeth. It then hardens into a durable restoration that can withstand biting forces.
While the use of amalgam has declined with the introduction of life-like colored fillings, it's still used for teeth like molars subject to high biting forces. With what we now know about the ill effects of mercury (which can make up to half of an amalgam mixture) is it safe to continue its use?
The American Dental Association has performed extensive research into amalgam safety. They've found that mercury is stabilized by the other metals in the amalgam. This prevents "free" molecules of mercury, the real source of harm to health, from escaping into the blood stream in the form of vapor. Although trace amounts of mercury vapor from the amalgam are released as a person chews, those levels are well below the threshold that could cause harm.
From a patient standpoint, the biggest drawback to dental amalgam isn't safety — it's the appearance of teeth it's used on. Silver fillings aren't considered attractive. And now there are viable filling alternatives that not only look like natural teeth but can withstand biting forces almost as well as amalgam. These materials include composite resins, mixtures of glass or quartz within resin, or glass and resin ionomers. Each of these has advantages and disadvantages depending on how and where they're applied.
After a thorough dental examination, we'll be able to advise you on what filling material will work best to produce the best result. And if we do suggest dental amalgam you can rest assured it will be a safe choice.

From the time they're born, you do everything you can to help your children develop a healthy body. That should include their teeth and gums. It's not over-dramatizing to say that what you do now may set the pattern for a healthy mouth for the rest of their life.
Here, then, are 4 things you should be doing for your children's oral health before they begin school.
Train them to brush and floss. Good hygiene habits have one primary purpose — remove dental plaque, a thin film of bacteria and food particles that builds up on tooth surfaces. Plaque is the number one cause of tooth decay and periodontal (gum) disease, so focus on brushing and later flossing as soon as their first teeth appear in the mouth, gradually training them to perform the tasks themselves. You can also teach them to test their efforts with a rub of the tongue — if it feels smooth and “squeaky,” their teeth are clean!
Keep your own oral bacteria to yourself. Children aren't born with decay-producing bacteria — it's passed on to them through physical contact from parents and caregivers. To limit their exposure to these “bad” bacteria, avoid kissing infants on the lips, don't share eating utensils and don't lick a pacifier to clean it off.
Eat healthy — and watch those sweets. Building up healthy teeth with strong enamel is as important to decay prevention as daily hygiene. Be sure they're getting the nutrients they need through a healthy diet of fresh fruits and vegetables, protein and dairy (and set a good example by eating nutritiously too). Sugar is a prime food source for bacteria that cause tooth decay, so avoid sugary snacks if possible and limit consumption to mealtimes.
Wean them off pacifiers and thumb sucking. It's quite normal for children to suck pacifiers and their thumbs as infants and young toddlers. It becomes a problem for bite development, though, if these habits continue into later childhood. As a rule of thumb, begin encouraging your children to stop sucking pacifiers or their thumbs by age 3.

In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?
“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.
How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.
With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.
In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.
While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.

The next time you visit your dentist you might see an item quite different from the other dental instruments and equipment in the office: a blood pressure cuff. Checking blood pressure is becoming a more common occurrence in dental offices across the country.
Abnormal blood pressure and some of the medications used to treat it are often a factor in some dental procedures, particularly if anesthesia is involved. But your dentist may also check your blood pressure for another reason: dental visits represent another avenue to screen for this condition that increases the risk of serious health problems.
Undiagnosed high blood pressure is a prevalent but often “silent” problem because the early stages of the condition may not display any symptoms. Many people first become aware they have an issue only after a blood pressure check at their family doctor, pharmacy or a health fair, for example. Otherwise, they could go months, even years without this vital knowledge about their health.
But while people may only visit their doctor once a year (or less) many see their dentist much more often, even twice a year, for routine cleanings and checkups. Including blood pressure screenings as a routine part of dental treatment could alert patients to a potential issue much earlier than their next doctor’s visit.
In fact, one study published in the Journal of the American Dental Association looked at a group of dental patients with no reported heart disease risk and who had not seen a doctor in the twelve months before their dental visit. During their visit their blood pressure was checked. Of those then referred to a physician for an abnormal reading, 17% learned for the first time they had an increased risk of cardiovascular disease.
It’s estimated about 80 million Americans have some form of cardiovascular disease and many don’t even know it. Diagnosing and controlling high blood pressure is a key factor in treating these life-threatening conditions. And many dentists are joining the fight by making this simple screening method a part of their dental care services.

Now that we’re into the New Year, it’s a good time to look over your list of resolutions. Did you remember to include dental health on your list? Here’s one simple resolution that can help keep your smile bright and healthy through the New Year and beyond: Floss every day!
Your oral hygiene routine at home is your first line of defense against tooth decay and gum disease. While brushing your teeth twice a day effectively removes much of the food debris and dental plaque from your teeth, brushing alone is not sufficient to remove all the plaque that forms on your teeth and around your gums. For optimal oral health, flossing once a day is also necessary.
Which teeth do you need to floss? Any dentist will tell you, “Only the ones you want to keep!” And yet according to a national survey of over 9,000 U.S. adults age 30 and older, nearly 70% don’t floss every day, and nearly one third admit that they don’t floss their teeth at all. Unfortunately, if you don’t floss, you’ll miss cleaning about a third of your tooth surfaces. When plaque is not removed, this sticky film of bacteria releases acids that cause cavities and gum disease. With dental floss, however, you can clean between the teeth and around the gums where a toothbrush can’t reach.
Flossing is an essential component of good oral hygiene. Still, daily flossing seems to be a harder habit to get into than brushing. Some people tense up their cheek muscles while flossing, making it harder to comfortably reach the back teeth, so remember to relax as you floss. If unwaxed floss doesn’t glide easily between teeth, try waxed floss. If you have trouble using traditional dental floss, you can try threader floss, which has a rigid tip, interdental brushes, floss picks, or a water flosser, which cleans by way of pressurized water.
It’s not too late to add one more resolution to your list, and flossing is a habit that will go a long way toward keeping you in the best oral health. And along with good dental hygiene at home, regular professional dental cleanings and checkups are key to a healthy smile.
