DentalAmalgamContinuestobeaDurableandSafeToothFilling

Recently, a number of new filling materials that mimic tooth color have come into popular use and, so far, have proven more durable than past versions. Even so, the traditional metal-based dental amalgam remains a viable choice, especially for less visible back teeth and their higher biting forces.

Used for more than a century, dental amalgam is a metal alloy composed of silver, mercury, tin and copper. The mixture is carefully proportioned so that potentially hazardous mercury is kept to a minimum and bonded with the other metals. Amalgam in its initial form is quite pliable so that it can be molded into the tooth structure under repair. Afterward it sets hard to form a durable filling that can withstand the daily force generated when we bite and chew food.

Besides durability, dental amalgam rarely causes an allergic reaction in a patient, and it’s easy for trained dentists to apply. On the downside, however, it can cause temporary temperature sensitivity in the tooth just after filling, and the tooth itself may require some removal of healthy structure to help keep the filling in place. And from an aesthetic point of view, its metallic appearance is considered unattractive especially for front teeth.

The presence of mercury in amalgam has also raised concerns over the years. “Free” mercury — atoms that escape through vapor emitted by the metal — can enter the bloodstream and potentially harm the nervous system. But after extensive study and research, U.S. and international health bodies including the American Dental Association have concluded any free mercury released during chewing is extremely low and well below any harmful levels. These studies have also found no ill effects in either children or adults with dental amalgam fillings.

Deciding on the type of filling material to use — dental amalgam or a newer composite resin, resin ionomer or glass ionomer — depends on a number of factors including the location of the teeth to be filled, the extent of decay and your personal preferences. Taking these into account, we’ll be happy to discuss which type of filling will suit you best for repairing decayed teeth.

ActorDavidRamseySaysDontForgettoFloss

Can you have healthy teeth and still have gum disease? Absolutely! And if you don’t believe us, just ask actor David Ramsey. The cast member of TV hits such as Dexter and Arrow said in a recent interview that up to the present day, he has never had a single cavity. Yet at a routine dental visit during his college years, Ramsey’s dentist pointed out how easily his gums bled during the exam. This was an early sign of periodontal (gum) disease, the dentist told him.

“I learned that just because you don’t have cavities, doesn’t mean you don’t have periodontal disease,” Ramsey said.

Apparently, Ramsey had always been very conscientious about brushing his teeth but he never flossed them.

“This isn’t just some strange phenomenon that exists just in my house — a lot of people who brush don’t really floss,” he noted.

Unfortunately, that’s true — and we’d certainly like to change it. So why is flossing so important?

Oral diseases such as tooth decay and periodontal disease often start when dental plaque, a bacteria-laden film that collects on teeth, is allowed to build up. These sticky deposits can harden into a substance called tartar or calculus, which is irritating to the gums and must be removed during a professional teeth cleaning.

Brushing teeth is one way to remove soft plaque, but it is not effective at reaching bacteria or food debris between teeth. That’s where flossing comes in. Floss can fit into spaces that your toothbrush never reaches. In fact, if you don’t floss, you’re leaving about a third to half of your tooth surfaces unclean — and, as David Ramsey found out, that’s a path to periodontal disease.

Since then, however, Ramsey has become a meticulous flosser, and he proudly notes that the long-ago dental appointment “was the last we heard of any type of gum disease.”

Let that be the same for you! Just remember to brush and floss, eat a good diet low in sugar, and come in to the dental office for regular professional cleanings.
