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.

You’re satisfied with your smile appearance except for one thing — your teeth aren’t as white and bright as you wish they could be. So, you’ve decided to do something about their dull yellow color.
You’re also thinking about buying a whitening product you can use yourself rather than a professional application. But you still want the answers to two questions: are home whitening kits safe? And, are they effective?
By and large the answer to the first question is yes — if you use it as directed. The whitening agents in FDA-approved products are in safe proportions to other ingredients and won’t cause any major health issues. That said, if you go beyond the instructed dosage you could damage your teeth, especially your enamel, and cause long-term problems with your dental care.
In addition, if you (or a family member) are still in your early teens, you may want to wait until you’re older. Although most permanent teeth have come in by puberty, their enamel still needs to mature. The chemicals in a whitening kit could be too strong for their under-developed enamel. It’s best to get our advice on whether your teeth are mature enough for whitening.
As to their effectiveness, home whitening kits should perform as their labeling indicates. But there are some differences in effects between a home kit and a professional application.
Although a home kit usually uses the same whitening agents (like carbamide peroxide), its strength is much lower than a professional treatment — about 10% of volume compared to around 30% in clinical solutions. This means it will take much longer to achieve the desired whitening effect that a professional application can in fewer sessions, and with less precision. In addition, home kits are only effective on surface staining of the enamel — discoloration within a tooth requires treatment by a dentist.
You can get satisfactory results from a home whitening kit. But before you make a purchase, consult with us first — we can advise you on what to look for in your purchase, as well as determine if your teeth can benefit from whitening at home.

Probably a day doesn’t go by that you don’t encounter advertising for dental implants. And for good reason: implants have taken the world of dentistry by storm.
Since their inception over thirty years ago, implants have rocketed ahead of more conventional tooth replacements to become the premier choice among both dentists and patients. But what is an implant—and why are these state-of-the-art dental devices so popular?
Resemblance to natural teeth. More than any other type of dental restoration, dental implants mimic both the appearance and function of natural teeth. Just as teeth have two main parts—the roots beneath the gum surface and the visible crown—so implants have a similar construction. At their heart, implants are root replacements by way of a titanium metal post imbedded in the jawbone. To this we can permanently attach a life-like porcelain crown or even another form of restoration (more about that in a moment).
Durability. Implant materials and unique design foster a long-term success rate after ten years in the 95-plus percentile. They achieve this longevity primarily due to the use of titanium as the primary metal in the implant post. Because bone has an affinity for titanium, it will grow and adhere to the post over time to create a well-anchored hold. With proper maintenance and care implants can last for decades, making them a wise, cost-effective investment.
Added stability for other restorations. While most people associate implants with single tooth replacements, the technology has a much broader reach. For example, just a few strategically-placed implants can support a removable denture, giving this traditional restoration much more security and stability. What’s more, it can help stop bone loss, one of the main drawbacks of conventional dentures. In like fashion, implants can support a fixed bridge, eliminating the need to permanently alter adjacent teeth often used to support a conventional bridge.
With continuing advances, implant technology is becoming increasingly useful for a variety of restorative situations. Depending on your individual tooth-loss situation, dental implants could put the form and function back in your smile for many years to come.

When is the best time to floss your teeth: Morning? Bedtime? How about: whenever and wherever the moment feels right?
For Cam Newton, award-winning NFL quarterback for the Carolina Panthers, the answer is clearly the latter. During the third quarter of the 2016 season-opener between his team and the Denver Broncos, TV cameras focused on Newton as he sat on the bench. The 2015 MVP was clearly seen stretching a string of dental floss between his index fingers and taking care of some dental hygiene business… and thereby creating a minor storm on the internet.
Inappropriate? We don't think so. As dentists, we're always happy when someone comes along to remind people how important it is to floss. And when that person has a million-dollar smile like Cam Newton's — so much the better.
Of course, there has been a lot of discussion lately about flossing. News outlets have gleefully reported that there's a lack of hard evidence at present to show that flossing is effective. But we would like to point out that, as the saying goes, “Absence of evidence is not evidence of absence.” There are a number of reasons why health care organizations like the American Dental Association (ADA) still firmly recommend daily flossing. Here are a few:
- It's well established that when plaque is allowed to build up on teeth, tooth decay and gum disease are bound to follow.
- A tooth brush does a good job of cleaning most tooth surfaces, but it can't reach into spaces between teeth.
- Cleaning between teeth (interdental cleaning) has been shown to remove plaque and food debris from these hard-to-reach spaces.
- Dental floss isn't the only method for interdental cleaning… but it is recognized by dentists as the best way, and is an excellent method for doing this at home — or anywhere else!
Whether you use dental floss or another type of interdental cleaner is up to you. But the ADA stands by its recommendations for maintaining good oral health: Brush twice a day for two minutes with fluoride toothpaste; visit your dentist regularly for professional cleanings and checkups; and clean between teeth once a day with an interdental cleaner like floss. It doesn't matter if you do it in your own home, or on the sidelines of an NFL game… as long as you do it!

While it might not be a big enough problem for other people to notice, we know you feel self-conscious and that’s enough to do something about it. Luckily, these small problems can easily be covered with a simple tooth-colored material known as dental bonding. The same material used to cover a cavity will be applied over these small imperfections where it will be shaped and then hardened into place to improve the shape, size or even color of a tooth.
Sometimes the imperfections we have are just no match for teeth whitening, bonding or other cosmetic treatments. But before you throw in the towel you may just end up being the perfect candidate for these thin porcelain shells.
