Today, more patients ask their dentists about white fillings because they want their teeth to look natural when they laugh, talk and smile. White fillings, also called composite fillings, are made from tooth-colored materials that restore the natural appearance of a decayed or previously filled tooth. Because they blend well with tooth enamel and don t look like fillings, your dentist may recommend them if the teeth to be restored are near the front of your mouth. A composite filling usually requires only one visit, during which the tooth is prepared and restored.
With a composite filling, your dentist will be able to preserve more of the natural tooth as the composite resin can be bonded to the tooth in thin layers and slowly built up to form a complete filling. A bright dental light will harden each layer before the next is applied.
If such a filling is not going to be enough to protect your damaged tooth, or if your tooth enamel is thin and will easily fracture, or if your tooth has had a root canal that weakened your tooth condition, your tooth may require additional protection such as a crown.
