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.

When Entertainment Tonight host Nancy O’Dell set out to teach her young daughter Ashby how to brush her teeth, she knew the surest path to success would be to make it fun for the toddler.
“The best thing with kids is you have to make everything a game,” Nancy recently said in an interview with Dear Doctor TV. She bought Ashby a timer in the shape of a tooth that ticks for two minutes — the recommended amount of time that should be spent on brushing — and the little girl loved it. “She thought that was super fun, that she would turn the timer on and she would brush her teeth for that long,” Nancy said.
Ashby was also treated to a shopping trip for oral-hygiene supplies with Mom. “She got to go with me and choose the toothpaste that she wanted,” Nancy recalled. “They had some SpongeBob toothpaste that she really liked, so we made it into a fun activity.”
Seems like this savvy mom is on to something! Just because good oral hygiene is a must for your child’s health and dental development, that doesn’t mean it has to feel like a chore. Equally important to making oral-hygiene instruction fun is that it start as early as possible. It’s best to begin cleaning your child’s teeth as soon as they start to appear in infancy. Use a small, soft-bristled, child-sized brush or a clean, damp washcloth and just a thin smear of fluoride toothpaste, about the size of a grain of rice.
Once your child is old enough to hold the toothbrush and understand what the goal is, you can let him or her have a turn at brushing; but make sure you also take your turn, so that every tooth gets brushed — front, back and all chewing surfaces. After your child turns 3 and is capable of spitting out the toothpaste, you can increase the toothpaste amount to the size of a pea. Kids can usually take over the task of brushing by themselves around age 6, but may still need help with flossing.
Another great way to teach your children the best oral-hygiene practices is to model them yourself. If you brush and floss every day, and have regular cleanings and exams at the dental office, your child will come to understand what a normal, healthy and important routine this is. Ashby will certainly get this message from her mom.
“I’m very adamant about seeing the dentist regularly,” Nancy O’Dell said in her Dear Doctor interview. “I make sure that I go when I’m supposed to go.”
It’s no wonder that Nancy has such a beautiful, healthy-looking smile. And from the looks of things, her daughter is on track to have one, too. We would like to see every child get off to an equally good start!
