What is the difference between white fillings and amalgam fillings?
Aesthetic Appearance
White fillings are designed to match the natural colour of teeth, making them blend seamlessly with the surrounding tooth structure. This aesthetic advantage is particularly beneficial for visible teeth, such as those in the front of the mouth.
Natural-Looking Smile
Since white fillings are colour-matched to your teeth, they provide a more natural-looking smile and are often preferred for cosmetic reasons.
Preservation of Tooth Structure
White fillings require less removal of healthy tooth structure compared to amalgam fillings, as they can be bonded directly to the tooth. This preserves more of the natural tooth.
Versatility
Composite resin can be used to repair both small and large cavities. It’s also versatile in reshaping chipped, broken, or worn teeth, making it a valuable material for cosmetic and restorative purposes.
Adhesion and Bonding
Composite fillings bond chemically to the tooth, providing additional support to the tooth structure and reducing the risk of fractures or leaks that can occur with amalgam fillings.
Reduced Sensitivity
White fillings may cause less sensitivity to hot and cold foods compared to amalgam fillings, as they do not conduct temperature as rapidly.
Less Risk of Allergic Reactions
Some individuals may have allergic reactions to the metals used in amalgam fillings. White fillings are made of composite resin and are generally well-tolerated by most individuals.
