Learn About Invisible Fillings for Your Teeth
Technology now offers attractive options for cavity restorations in dental care. Called composites, these new tooth-colored fillings are excellent choices for front teeth and other repairs that might be visible. Composites duplicate the natural appearance of a tooth in restoring decayed teeth or repairing a defect.
What Material Is Used in the Composite?
Composites are made from a mixture of microscopic plastic and ceramic resin particles. Another type of tooth-colored filling is called a resin ionomer, which releases fluoride useful for preventing tooth decay.
Besides Their Cosmetic Value, What Other Benefits Do Composites Provide?
The bonding process used in restoration provides strength to the tooth, making it more structurally sound. It also seals the tooth, decreasing the chance of sensitivity to hot and cold. Some composites made with materials releasing fluoride are ideal for treating root decay, a condition when gums recede, exposing tooth roots to more cavity-causing plaque. These fluoride-releasing materials also are useful for filling decayed baby teeth.
What Is the Process for Treatment?
Following removal of the decayed area, a mild acid solution is used to prepare the tooth's surface for bonding. A bonding agent is then brushed over the surface. Next, several layers of the composite are applied. For a natural appearance, the dentist matches the color of the composite to the tooth.
Then, it is chemically hardened or cured with a special light and finally polished for a natural-looking finishing touch.
How Durable Are Composite Fillings?
In a five-year clinical study, some of the resin materials demonstrated 100% effectiveness for adhesion and retention. Like other types of fillings, they may require periodic replacement. While the material is very durable, they may not perform quite as long as silver fillings or amalgams for their resistance to the rigors of grinding and chewing.
Scheduling regular dental exams is an important part of good oral hygiene. Your dentist will check your invisible fillings each time to ensure their performance.

Sterilization of Dental Equipment
The times are trying enough without having to worry about a visit to the dentist. There is much talk about the transmission of disease in any given medical environment. Well, we're here to say dentistry in our practice still is a safe and healthful experience. And it's not just a matter of trust.
It took the AIDS epidemic to bring it to the public eye. But we've been guarding against it at our dental office since the day we opened our doors.
I'm talking about communicable disease. AIDS is the one you hear most about, but there are others. A quiet new killer (HCV, hepatitis C virus) currently infects about four million Americans who will never be able to rid themselves of it. Here at the office we're also aware that hepatitis B, tuberculosis, influenza-even the common cold-are communicable. The good news is that the same strict standards of asepsis (cleanliness) we use against one disease also defend us against all the others.
You may not be aware of all we do to ensure your protection from cross-communicated viruses during your dental care. In fact, it's a large part of our day, and we're committed to the task.
We use disposable items wherever we can. Every surface in the operatory is secured against airborne bacteria with physical barriers. Our sterilization procedures are complex, monitored by an outside agency, and, not incidentally, much more than OSHA, the American Dental Association, the Centers for Disease Control, and local agencies require.
Metal instruments are cleansed in an ultrasonic bath before autoclaving in chemical pressurized heat. Hand pieces, for instance (you know them as drills), take an hour's preparation-heat-treated then cooled-for each patient. We disinfect everything in sight.
All this costs, but it's worth it.
We wouldn't be here if we didn't care about you, your health, and your good looks. We want you to feel comfortable, all the time. Please ask about our sterilization program and we'll be more than happy to show you what we're doing.
You know we care about open communication in our dental office. This letter is another way we hope to show it.
