Depending on your age and the severity/location of your cavity, you may have received either a white filling or a silver filling in your tooth. Though silver (amalgam) fillings have been in use longer, they are by no means outdated. Both white (resin) and amalgam fillings have their place in dentistry.
At our dental clinic, we help patients in Red Deer choose the best options based on durability, comfort and long-term results. Dr. Caroline has more than 35 years’ experience filling cavities in kids and adults, and she is always happy to help you make the best choice for you and your family.
What Are White Fillings?
White fillings, also known as composite fillings, are made from a tooth-coloured resin designed to blend seamlessly with your natural teeth. Their biggest advantage is appearance. The material is carefully colour-matched, making the filling nearly invisible when you smile or speak. This makes white fillings ideal for both front and back teeth.
They also bond directly to the tooth, which allows us to preserve more of your natural tooth structure. This bonding process can help strengthen the tooth and reduce the risk of fractures over time.
What Are Silver Dental Fillings?
Silver fillings do contain a small amount of silver, but they are actually an amalgam of various metals. This type of dental filling has been used for decades and are known for their strength and longevity. They are made from a combination of metals and are often used in molars where chewing pressure is highest.
While durable, they are very noticeable due to their dark colour. Over time, they can also cause the surrounding tooth to appear grey or darker. Unlike white fillings, silver fillings do not bond to the tooth. This means it might be necessary to remove some healthy parts of the tooth structure to secure the filling in place. The metal filling stays in place thanks to a clever undercut shape – larger at the bottom and smaller at the top – that prevents it from moving.
The Key Differences Between White & Silver Fillings
The main differences between white and silver fillings come down to appearance, tooth preservation and overall patient preference. White fillings are the most natural-looking option. Silver fillings are strong and long-lasting but are more visible and may require removal of more of the natural tooth.
With advancements in dental materials, white fillings are now durable enough for most situations, making them the preferred choice for many patients.
There’s Usually No “Correct” Dental Filling Choice
Today, most patients choose white fillings because they offer both function and aesthetics. They restore the tooth while maintaining a natural appearance, which is especially important if your tooth is easily visible. They also align with a more modern approach to dentistry that focuses on preserving as much natural tooth structure as possible.
Silver fillings may sometimes still be the sturdiest options for certain cavities, and you can often depend on them to last for multiple decades before needing replacement. The best filling option for you depends on the size and location of the cavity, as well as your personal preferences.
