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.

Have you started orthodontic treatment recently? Are you having a little trouble getting used to your braces? If so, you are not alone: Everybody goes through an adjustment period during which they momentarily wonder if they’ll really ever get used to this. Don’t worry — you will! And we’ve never heard anyone say, on the day their braces come off and their new smile is revealed, that they aren’t glad they went the distance. Just ask Houston Rockets all-star center Dwight Howard, who discussed his own orthodontic treatment in a recent interview.
“I’m sure I was no different than anyone else who has ever had braces,” he told Mediaplanet. “At first I hated them so much… That changed once I got used to them and I actually grew to love them.” What’s Howard’s advice? “Do exactly what your orthodontist says and know that the outcome is well worth it in the end.” We couldn’t agree more! Here are some tips for wearing braces comfortably:
- Hard & Chewy Foods: If you love fresh fruits and vegetables, that’s great; there’s no reason to give them up, just the really hard ones. You don’t want to bite into an apple or carrot or any other hard foods like bagels and pizza that have any “size” to them. Small pieces may be ok as long as they can’t bend your wires. Chewy, sticky candy should really be avoided completely. Same with soda, sports drinks and so-called energy drinks because they contain acids that promote tooth decay and can cause a lot of damage around the braces.
- Effective Oral Hygiene: Keeping your teeth clean is more important than ever, but also more challenging than ever. It’s easy for food to get stuck under wires and around brackets, but failing to remove it can cause tooth decay, gum irritation and soreness. Therefore, the cleaner your teeth and your braces are, the healthier you will be. Use interdental cleaning brushes and/or a floss-threader to get behind your wires. A mouthrinse can also help strengthen teeth and keep bacteria in check. If you have any questions about how to clean between your teeth, please ask for a demonstration at your next visit.
- Pain Relief: Some soreness at the beginning of orthodontic treatment is normal. To relieve it, you can use an over-the-counter pain reliever and/or a warm washcloth or heating pad placed on the outside of the jaw. If brackets or wires are rubbing against the inside of your cheeks or lips, try applying wax to these areas of your braces. If this does not offer enough relief, we may be able to trim the end of a poking wire. Call us if you need help with this.
Our goal is to make your orthodontic treatment as comfortable as possible on the way to achieving your all-star smile.
