Most people have fillings of one sort or another but today, because we are much more conscious of our smile, we can choose a natural looking alternative - the composite or tooth-coloured filling.
A composite resin is a tooth-coloured plastic mixture filled with glass (silicon dioxide) first introduced in the 1960s. Originally only used for front teeth because of their softer nature, modern improvements to their composition make them generically suitable today.
Composite fillings are more difficult to place than silver fillings so may take your dentist longer to complete. On back teeth, they are not available on the NHS and must be paid for. The main advantage of composite fillings is there aesthetic appeal.
