Fillings can help your smile by restoring decay and yes, beautifying how your teeth look. How can this be? Aren't fillings made of silvery-looking metal? Some are, but most are tooth-colored, explain your family dentists in Sacramento, CA, Dr. Jeff DiMariano and Dr. Shaina DiMariano. Blending with and strengthening natural tooth enamel, today's dental fillings are amazingly lifelike in every way.
What is a dental filling?
It's a restorative dental treatment which repairs a cavity--that is, a hole in tooth enamel caused by the corrosive effects of acid in the mouth. Oral bacteria contained in soft plaque and hard tartar, or calculus, secrete this harmful acid.
Additionally, some people are more prone to decay than others. Softer, thinner enamel, a carb-rich diet, acid reflux disease, oral trauma and deeply grooved tooth surfaces increase the chances of developing decay.
Most American adults have at least three fillings to restore decay, says the Centers for Disease Control in Atlanta. A filling replaces damaged tooth structure. In the past, metal amalgam was the only choice of material. Strong and durable, amalgam still can be the proper choice for some decay situations.
More likely though, your Sacramento, CA, dentist will choose composite resin, porcelain, or glass ionomer to fill your cavity. These high-tech materials are versatile, blend in with surrounding enamel and well-withstand the substantial pressure of biting and chewing. They also require far less enamel removal and preparation to install than old-fashioned materials do, leaving more tooth structure in place.
The filling treatment
Dr. DiMariano uses a high-speed drill and other tools to remove the decayed portions of your tooth. The dentist does this with benefit of local anesthetic so you're comfortable during the treatment.
After the site is prepared, the dentist chooses the proper material for your filling. Composite resin, a blend of glass and acrylic, is layered into a small to moderate-sized filling. A special light hardens each layer for maximum strength. Glass ionomer, a mix of fluoride and glass, works well on the buccal, lingual or interdental surfaces and helps prevent future decay. Porcelain inlays and onlays really are partial crowns. Customized to fit over the top of molars or in between the cusps or corners, inlays and onlays are permanently bonded in place.
The American Dental Association (ADA) recommends the following as great strategies for reducing dental decay or preventing is altogether:
- Brush twice a day with a fluoride toothpaste.
- Floss daily.
- Eat a diet low in carbohydrates.
- Avoid between-meal snacks.
- Stay hydrated with plenty of water, avoiding dry mouth, increasing saliva and rinsing tooth surfaces.
- Get semi-annual examinations and cleanings.
- Ask your dentist about in-office fluoride treatments and plastic sealants for more protection.
The best filling...
It's no filling at all. But, if decay happens, trust Dr. Jeff and Shaina DiMariano to uncover and treat it with the best materials available. If you have questions about our restorative procedures, including dental fillings, please call our Sacramento, CA, office at (916) 929-3898!
Over the last century and a half millions of people have had a tooth cavity filled with “silver” amalgam. Perhaps you’re one of them. The use of this effective and durable filling has declined in recent years, but only because of the development of more attractive tooth-colored materials.
At the same time there’s another issue that’s been brewing in recent years about this otherwise dependable metal alloy: the inclusion of mercury in amalgam, about half of its starting mixture. Various studies have shown mercury exposure can have a cumulative toxic effect on humans. As a result, you may already be heeding warnings to limit certain seafood in your diet.
So, should you be equally concerned about amalgam fillings — even going so far as to have any existing ones removed?
Before taking such a drastic step, let’s look at the facts. To begin with, not all forms of mercury are equally toxic. The form causing the most concern is called methylmercury, a compound formed when mercury released in the environment combines with organic molecules. This is the form certain large fish like salmon and tuna ingest, which we then ingest when we eat them. Methylmercury can accumulate in the body’s tissues where at high levels it can damage various organ systems.
Dental amalgam, on the other hand, uses elemental mercury. Dentists take it in liquid form and mix it with a powder of other metals like silver, tin and copper to create a pliable paste. After it’s placed in a prepared cavity, the amalgam hardens into a compound in which the mercury interlaces with the other metals and becomes “trapped.”
Although over time the filling may emit trace amounts of mercury vapor, it’s well below harmful levels. You’re more likely to encounter “un-trapped” mercury in your diet than from a dental filling. And scores of studies over amalgam’s 150-year history have produced no demonstrable ill effects due to mercury.
Although it now competes with more attractive materials, amalgam still fills (no pun intended) a necessary role. Dentists frequently use amalgam in less visible back teeth, which encounter higher chewing pressures than front teeth. So, if you already have an amalgam filling or we recommend one to you, relax — you’re really in no danger of mercury poisoning.
Q: I’ve never heard these terms used in dentistry. What are they?
A: In the decorative arts, an inlay refers to a small piece of distinctive material that’s set into a larger matrix: a mother of pearl accent worked into the lid of a wooden box, for example. In dentistry, it means something similar: a filling (or restoration) that’s fabricated in a dental laboratory, and then set into a tooth in an area that has been damaged or lost.
Q: What’s the difference between inlays and onlays?
A: An inlay is made to fit in between the cusps (small points or ridges) of a back tooth (molar or premolar), and it covers only a small region of the biting surface of the tooth. If the restoration covers one or more of the cusps, it’s an onlay.
Q: Why would I need to have one of these restorations?
A: When a tooth has suffered damage (from decay or trauma, for example), and the affected area is too large to fill with a simple filling — but not large enough to need a full crown (cap) — then an inlay or onlay may be just right. Both of these procedures are considered “indirect fillings,” because the restoration itself is custom-fabricated in a laboratory and then bonded to the tooth in the dental office.
Q: What is the procedure for getting an inlay or onlay?
A: It’s similar to having a crown placed, in that it typically takes more than one office visit — yet an inlay or onlay involves less removal of tooth structure than a crown would require. On the first visit, after the area has been anesthetized (usually with a numbing shot), any decay is removed, and the tooth is shaped to receive the restoration. Next, a model of the tooth is made (either with putty or in digital form), and the tooth receives a temporary filling. The laboratory uses this model to create the actual inlay or onlay, which may take a few days; it is then permanently attached to the tooth on a second visit to the office. However, with today’s advances in CAD/CAM (computer aided design/ manufacturing) technology, some inlays or onlays can be made in the office and placed in the same visit.
Q: What else do I need to know about these tooth restorations?
A: Both inlays and onlays are strong and long-lasting restorations that need no more care than you would normally give your teeth: namely, regular brushing and flossing, and periodic checkups at our office. But because they don’t require the removal of a great deal of natural tooth material, they are considered relatively conservative treatments. After a thorough dental examination, we can recommend the type of tooth restoration that’s most appropriate in your individual circumstances.
