Tooth Color Fillings

The Process of Filling a Tooth

There are many reasons why a tooth may need to be filled or restored: decay and chipping are two common ones. No matter which material is chosen, the procedure is almost the same. After the area has been anesthetized (usually by a numbing injection), the tooth is “prepared” by removing decay and making it ready for the restoration. Next, the filling material is placed directly into the tooth. Once it has securely bonded to the tooth structure, the process is essentially complete. Now, here's the difference: In order to achieve a good structural bond with a traditional amalgam filling, it is often necessary to shape the tooth by making a series of “undercuts” that help hold the material in place. This means that some healthy tooth material must be removed, leaving less of the tooth's structure intact. In time, the structurally-weakened tooth can be prone to cracking. But composite resin fillings don't require undercutting to make a strong union — instead; they form an intimate physical and mechanical bond directly to the prepared tooth. This more conservative treatment may ultimately lead to a better and longer-lasting restoration.

You can dramatically decrease your risk of cavities and other dental diseases simply by:

  • Brushing your teeth twice a day with fluoride toothpaste
  • Flossing daily
  • Eating a balanced diet
  • Visiting the dentist regularly.

Advantages of Tooth Colored Fillings

There are many advantages of using these fillings over other materials used for restoring a tooth. The main advantage that one can get by using white fillings is the esthetic finish of the restoration. The restorative material is available in many different shades to match the shade of the tooth to be restored, thereby providing superior esthetics, which is not possible when using materials like amalgam or gold.

When material like amalgam has to be placed, lot of tooth structure has to be compromised in order to hold the material in its position within the tooth. This is because, there is no direct bonding between amalgam and the tooth, and it is only held with mechanical retentive properties of the preparation. In tooth color fillings, a direct bonding between the tooth and the restorative occurs with the help of a bonding agent. This reduces the amount of tooth reduction that needs to be made, thus preserving the strength of the tooth being restored.

Earlier versions of this filling material had problems like development of sensitivity in the restored tooth. This was mainly caused due to the etching process before filling the tooth and also due to marginal leakage between the tooth and the restorative material. However, advent of the material has eliminated etching process and negated the marginal leakage, thereby reducing the occurrence of sensitivity.

The improved strength of the tooth color fillings has resulted in better resistance to fracture, especially in fillings that do not have much support from the tooth. So, fillings using tooth colored restorative materials seem to have better life in comparison to materials like amalgam or gold.
