Prior to our modern advances in oral healthcare, dentists used inexpensive silver and mercury fillings to seal cavities and unwanted craters. The problem with this method is that silver fillings do not bond well to teeth. This process of adding silver fillings included what is known as an “undercut,” which allowed the silver to bond to the tooth. While initially this solved the issue of the cavity, the undercut typically caused the tooth to become weaker over time.
Modern oral healthcare has deemed that composite or porcelain fillings are much stronger, safer, and also more natural-looking. Composite fillings are your best bet for creating a long-lasting and healthy smile. With no discoloration and no weakened teeth, composite fillings are an optimal material to replacing your silver-mercury fillings.
