When a tooth is subjected to acid from plaque for long enough, a small cavity will form. Many times these small cavities can be restored with a simple filling. Dr. Reichenberger knows that most people would prefer tooth colored fillings if they do indeed need a tooth restored. He routinely places these fillings with an emphasis on esthetics and with great care so they will last a long time. Other filling materials are available for special circumstances, but those are rare.
