A little more about Composite Fillings
A composite resin is a tooth coloured plastic mixture filled with glass (silicone dioxide) first introduced in the 1960s. Originally only used for front teeth, because of their softer nature, modern improvements to their composition make them more suitable today.
Composite fillings are more difficult to place than silver fillings, so may take your dentist 15-20 minutes longer to complete. As composite fillings are a cosmetic treatment, they are not available on the NHS and must be paid for.
