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. A composite filling usually requires only one visit, during which the tooth is prepared and restored. An advantage of composite fillings, as compared with other dental restorations, is that they require less of the healthy part of a tooth to be removed to hold the filling in place. This is due to composite materials ability to bond to teeth adhesive. Composites are preferable for obvious cosmetic reasons, but if the decayed area is large or is subject to heavy chewing pressure, your dentist may recommend another type of material or restoration.
