There's no way to disguise the fact that you've had cavities when your teeth are filled with silver amalgam fillings. Luckily, tooth-colored fillingsfillings make it impossible for anyone to tell that you've had dental work. Lexington, KY, dentists Dr. William Lee, Dr. Pada Chalothorn and Dr. William Cartee of TLC Dentistry discuss the advantages of tooth-colored fillings.

What are tooth-colored fillings?

Composite resin, a material made with a mixture of flexible plastic and powdered glass, is often used to fill teeth, repair damage or change the shape of a tooth. The material is an excellent choice if you want your dental work to blend in with your tooth enamel. Composite resin is available in a variety of shades tinted to match the most common tooth colors. Once the material is added to your tooth and cured with a hardening light in our Lexington office, your restored tooth will look just like the others.

What are the benefits of tooth-colored fillings?

Tooth-colored fillings offer several benefits in addition to a more natural appearance, including:

  • No Cracks: Silver amalgam shrinks and expands when exposed to heat and cold. Over time, these changes can result in cracks in your filled tooth. Cracks increase the risk that your tooth will break and also provide a pathway for bacteria to invade your tooth. Unlike silver amalgam, composite resin doesn't expand when it's exposed to temperature variations, which means cracking is less likely to be an issue.
  • Stronger Teeth: Filling a cavity involves removing part of the healthy tooth structure surrounding the decayed area. Removing the healthy structure can weaken your tooth and increase the likelihood of a crack or break. When a tooth-colored filling is used, less healthy structure needs to be removed. The fillings also bond to your teeth, which makes them stronger.
  • No Discolorations: As silver amalgam fillings age, they may darken your tooth. Because your composite resin filling matches the shade of your tooth, you won't have to worry about discolorations in the future.

Tooth-colored fillings improve your appearance and protect your teeth. If you're concerned about a toothache or need to schedule your next checkup, call Lexington, KY, dentists Dr. William Lee, Dr. Pada Chalothorn and Dr. William Cartee of TLC Dentistry at (859) 223-8987 to schedule an appointment.

FrequentlyAskedQuestionsaboutInlaysandOnlays

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.
