For many years, amalgam fillings were the most common type of filling used to treat cavities. However, research has shown that amalgam fillings can cause cracks in teeth over time, leading to further dental problems. As a result, many dentists now recommend using composite fillings instead. In this article, we'll explore why amalgam fillings cause cracks in teeth and why composite fillings are a better option for dental fillings.
Amalgam fillings are made from a mixture of metals, including mercury, silver, and tin. These fillings have been used for over 150 years and are known for their durability and longevity. However, over time, the metal in these fillings can expand and contract with changes in temperature, putting pressure on the tooth and causing it to crack. Additionally, amalgam fillings do not bond directly to the tooth, which can weaken the tooth structure and cause further damage.
Composite fillings, on the other hand, are made from a mixture of plastic and glass. These fillings bond directly to the tooth, which can help to strengthen the tooth structure and prevent further damage. Additionally, composite fillings do not expand and contract with temperature changes, making them a safer and more durable option in the long run.
Composite fillings also have the advantage of being more aesthetically pleasing than amalgam fillings. Composite fillings can be matched to the color of your teeth, making them virtually invisible. This can be especially important for front teeth or teeth that are visible when you smile.
Another advantage of composite fillings is that they require less drilling than amalgam fillings. This means that more of the natural tooth structure can be preserved, which can help to prevent further damage or decay. Additionally, composite fillings are less likely to cause tooth sensitivity, which can be a problem with amalgam fillings.
Overall, composite fillings may be a safer and more effective option for dental fillings than amalgam fillings. They are less likely to cause cracks in teeth, bond directly to the tooth, are aesthetically pleasing, and require less drilling.
