Advances in modern dental materials and techniques, increasingly offer new ways to create more pleasing, natural looking smiles in the context of no amalgam fillings.

Researchers are continuing their often decade long work developing attractive materials, such as ceramic and resin compounds that mimic the appearance of natural teeth. Today, more patients ask their dentists about white fillings because they want their teeth to took natural when they laugh, talk and smile.

White fillings, also called composite fillings or no amalgam fillings are made from tooth-coloured 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 fillings, 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 adhesively. 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. Some people may experience some sensitivity to hot and cold temperatures in the newly filled tooth for a few days or as long as a week. If the sensitivity continues beyond that time, contact your dentist.

Some, but not all white fillings may be more expensive than other dental materials, but most patients find these natural-looking restorations well worth the additional cost. White fillings, like other dental materials, may require periodic replacement. If the edge of the filling eventually pulls away from the tooth, bacteria can get between the filling and the enamel and eventually may cause decay. Tooth decay over time may develop elsewhere on the tooth. Regular dental check-ups are important because they allow the dentist to detect a problem in the early stage. In the end – every restorative material has advantages and disadvantages. …Composite resin white fillings are the most common alternative to dental amalgam.
