Dental fillings have long been used to restore teeth damaged by decay or trauma. While traditional silver fillings were once the standard, many dental practices now use tooth-coloured restorations, also known as composite restorations, for a more natural and aesthetic look. Here’s what you need to know about dental fillings and the advantages of tooth-coloured restorations.
Disadvantages of Silver Fillings
Silver or amalgam fillings contain up to 50% mercury and can expand and contract with temperature changes, leading to tooth cracking and breaking. Over time, the metal in silver fillings can corrode and cause stains on teeth and gums. Silver fillings can also wear down, making the tooth more vulnerable to decay.
Advantages of Tooth-Colored Restorations
Tooth-coloured restorations are made of a composite resin material that can be colour-matched to your natural teeth for a seamless look. Unlike silver fillings, they do not contain mercury and are less likely to expand or contract with temperature changes, reducing the risk of cracking or breaking the tooth. Since they are bonded to the tooth, they can strengthen the structure and prevent further damage.
