White fillings are a natural-looking alternative to the traditional silver amalgam filling. Their main advantage is their aesthetic appeal – because they’re tooth-coloured, they don’t stand out.
The main disadvantage is that they may not last as long as silver amalgam fillings, depending on the depth of the cavity in your tooth, and its position in the mouth. Having said that, white fillings are now being made with materials that last a similar time to silver amalgam, and are so far proving very successful.
Your dentist can give you the best advice about how long to expect your filling to last.
