What Steps Are Involved in Filling a Tooth?

First, a drill, air abrasion instrument, will be used to remove the decayed area. If required,local anesthesia is given around the tooth to be filled. Next, the area will be tested to determine if all the decay has been removed. Once the decay has been removed, the space is prepared for the filling by cleaning the cavity of bacteria and debris. If the decay is near the pulp,a liner made of glass ionomer, dycal or other material is used to protect the nerve. Several additional steps are required for tooth-colored fillings and are as follows. After the removal of decay the area has been cleaned, the tooth-colored material is applied in layers. Next, a special light that "cures" or hardens each layer is applied. When the multilayering process is completed, the shape to the composite material will be given to the desired result, trim off any excess material, and polish the final restoration.

Why tooth colored material is used?

1. Aesthetics -- the shade/color of the composite fillings can be closely matched to the color of existing teeth. Composites are particularly well suited for use in front teeth or visible parts of teeth.
2. Bonding to tooth structure -- composite fillings actually chemically bond to tooth structure, providing further support.
3. Versatility -- in addition to use as a filling material for decay, composite fillings can also be used to repair chipped, broken, or worn teeth.
4. Tooth-sparing preparation -- sometimes less tooth structure needs to be removed compared with amalgam fillings when removing decay and preparing for the filling.

How should I care for my teeth with fillings?

To maintain fillings, you should follow good oral hygiene practices --, brushing with a fluoride toothpaste, and flossing at least once daily.
