Types of dental filling
A number of different fillings can be used by your dentist:
Composite (white) fillings - Made from natural tooth coloured resins that are more aesthetically pleasing and can be matched to the same colour as natural teeth.
Amalgam (silver) fillings - Made from an amalgamation of different metals that are silver in appearance. Amalgam fillings are resistant to wear; however, due to their colour they are more noticeable than composite fillings and are not usually used in very visible areas, such as front teeth.
Porcelain fillings - Called inlays or onlays, they are made by a technician in a dental laboratory and bonded to the tooth. They can be matched to the colour of the tooth, are resistant to staining, and extremely durable.
After your dental filling
Your mouth, gums and tongue may feel numb for a few hours after your dental filling. This is because the local anesthetic will take time to wear off so you may have difficulty talking, chewing and drinking. You may also experience a tingly feeling in the area as feeling returns.
The tooth may be more sensitive than usual to cold and heat for a few days to a week after your procedure. Tell your dentist if symptoms worsen or continue longer than a week because this could indicate changes within the pulp tissue (nerve) that may require further treatment.
