Amalgam and Bonded Resins (Fillings)
(En Español)
Tooth-colored restorations have been used in dentistry for a long time. Several variations of these materials have been used in front teeth for many years. The newest generation of tooth-colored filling materials (resins) is also used to restore cavities in back teeth. This is especially true when the restoration would be easily visible when you talk or smile. The use of silver amalgam filling materials in small- to medium-sized restorations is declining. These posterior (back) tooth-colored resins can be expected to last for several years. A reasonable estimate at this time is approximately 10 to 12 or more years. Longevity of the resin fillings (and silver fillings) is a function of the position and size of the filling, the care the patient gives it, and the foods the patient eats.
Advantages
- Requires less drilling in back teeth.
- Inhibits new cavity formation.
- Natural appearance.
- Restores a high percentage of original tooth strength.
- Only one appointment required for completion.
Disadvantages
- Technique Sensitivity (Harder to place than silver.)
- Cost more than silver.
- Rarely used in patients who have grinding or clenching habits.
- Only applicable to teeth with significant damage or decay.
- They take longer to apply.
Resin restorations are among the most conservative restorations in dentistry today. They require the least amount of drilling. The smaller any filling can be, the longer it will last. They are best for small to medium fillings. In areas where the display of metal from a silver filling would be unsightly, they are of great cosmetic importance.
