Tooth colored fillings, also called white fillings, are dental fillings that restore and mimic the natural appearance of tooth structure. In addition to restoring teeth that have fractured or decayed, tooth colored fillings may also be used cosmetically to change the size, color and shape of teeth. This quality is particularly useful in closing gaps between teeth; repairing chipped teeth and making teeth appear to be more straight or even.
Are Tooth Colored Fillings Right For Me?
Among the advantages of tooth-colored fillings are:
- Life-like aesthetic qualities
- The preservation of more natural tooth structure
- Optimal bio-compatibility
- Minimal risk of allergic reaction
- No development of metal sensitivity.
What are the advantages of tooth colored fillings (white fillings)?
- They closely match natural tooth color and appearance.
- They bond to tooth structure chemically and thus do not require the placement of slots, grooves or pins in healthy tooth structure to mechanically retain them.
- The bonding of white fillings to the tooth restore 85% – 95% of the original strength of the tooth.
- They completely harden in seconds instead of days required by some other materials.
- Tooth sensitivity, if any, due to composite resin use is minimal and brief.
- They may be used on front and back teeth without compromising esthetics.
- If damaged they can be repaired.
What are the disadvantages of tooth colored fillings (white fillings)?
- Frequent and/or prolonged exposure to dark liquids (coffee, tea, red wine) and foods with rich dyes (curries, etc.) may stain them.
- They are not as strong as metal fillings.
- Frequent and/or prolonged exposure to liquids with a high alcohol content may degrade them.
- Dental insurance companies frequently impose a surcharge, payable by the patient, for placement of white fillings instead of dental amalgam, especially for back teeth.
Most tooth colored fillings (white fillings) are composite resin fillings
Tooth colored fillings were first introduced to the American public in the mid 1960’s. Since that time tooth colored filling materials have undergone continual improvements in durability, esthetics and material handling. The most versatile and widely used tooth colored filling today is composite resin filling. A composite is a material in which filler particles are encased in and bound together by a hard matrix material. For composite resin fillings a fluid matrix of an acrylic, called BIS-GMA, is hardened around glass filler particles to form composite resin. Trace metals (e.g. cobalt, gold and copper) give color to the glass while zirconium and titanium oxides add opacity.
