Decay is somewhat common, but when discovered it does require immediate attention by removing decayed enamel and sealing the tooth to avoid more damage. Material selection is determined by necessity. Composite materials are less obvious than their amalgam counterparts, but lack durability.

Technology in terms of composite fillings is improving quickly, making them viable for most instances, including molars.

Composite fillings do not require removal of natural tooth material, as amalgams do. Dentists try to avoid unnecessary removal of enamel; therefore composite fillings are increasingly popular with dental professionals.

The new technology is beyond some dentists. The modern technology requires more practiced skill, making it important for a patient to discuss options with their dentist prior to undertaking a new filling. Composite fillings require an examination and X-rays, in order to properly evaluate the extent of decay.

Following removal of decayed enamel, the area is carefully cleaned to prevent further decay. The area to be filled is coated with an adhesive prior to the filling being placed. Dentist and patient will collaborate to establish a comfortable bite. Lastly, the filling will be hardened with a specialized dental light.
