EvenwithMercuryDentalAmalgamisaSafeChoiceforToothFilling

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.

ArianaGrandeBreaksFree-ofHerWisdomTeeth

Via a recent Instagram post, pop diva Ariana Grande became the latest young celebrity to publicly acknowledge a dental milestone: having her wisdom teeth removed. The singer of hits such as “Break Free” and “Problem” posted an after-surgery picture of herself (wearing her signature cat-eye eyeliner), with a caption addressed to her teeth: “Peace out, final three wisdom teeth. It’s been real.”

With the post, Grande joined several other celebs (including Lily Allen, Paris Hilton and Emile Hirsch) who have shared their dental surgery experience with fans. Will "wisdom teeth removal" become a new trending topic on social media? We aren’t sure — but we can explain a bit about the procedure, and why many younger adults may need it.

Technically called the “third molars,” wisdom teeth usually begin to emerge from the gums between the ages of 17 and 25 — presumably, around the same time that a certain amount of wisdom emerges. Most people have four of these big molars, which are located all the way in the back of the mouth, on the left and right sides of the upper and lower jaws.

But when wisdom teeth begin to appear, there’s often a problem: Many people don’t have enough space in their jaws to accommodate them. When these molars lack sufficient space to fully erupt (emerge), they are said to be “impacted.” Impacted teeth can cause a number of serious problems: These may include pain, an increased potential for bacterial infections, periodontal disease, and even the formation of cysts (pockets of infection below the gum line), which can eventually lead to tooth and bone loss.

In most cases, the best treatment for impacted wisdom teeth is extraction (removal) of the problem teeth. Wisdom tooth extraction is a routine, in-office procedure that is usually performed under local anesthesia or “conscious sedation,” a type of anesthesia where the patient remains conscious (able to breathe normally and respond to stimuli), but is free from any pain or distress. Anti-anxiety medications may also be given, especially for those who are apprehensive about dental procedures.

So if you find you need your wisdom teeth extracted, don’t be afraid to “Break Free” like Ariana Grande did; whether you post the results on social media is entirely up to you. If you would like more information about wisdom tooth extraction, please call our office to schedule a consultation.
