In recent years, there has been a shift towards using white fillings instead of silver fillings for dental cavities. White fillings, also known as composite fillings, are made from a mixture of resin and small glass particles. They are designed to match the natural color of your teeth, providing a more aesthetically pleasing result.
The main advantage of white fillings is their appearance. They blend in with your natural tooth color, making them virtually invisible when you smile or talk. This is particularly beneficial for cavities in visible areas of the mouth, such as the front teeth. With white fillings, you can maintain a natural and attractive smile.
Another advantage of white fillings is that they bond to the tooth structure. This means that less healthy tooth material needs to be removed to place the filling, compared to silver fillings. This conservative approach helps to preserve the strength and integrity of your teeth.
White fillings also have the advantage of being mercury-free. Silver fillings, or amalgam fillings, contain a combination of metals including mercury. While the mercury in amalgam fillings is considered safe for most individuals, some people may have concerns about its presence in their mouths. White fillings provide a metal-free alternative that satisfies those concerns.
However, it’s important to note that silver fillings still have their place in dentistry. They have been used for many years and have a proven track record of durability. Silver fillings are particularly useful for restoring cavities in areas with heavy chewing forces, such as the molars. They are strong and can withstand the pressure of chewing and grinding.
In terms of cost, white fillings tend to be more expensive than silver fillings. The materials used for white fillings are generally more costly, and the procedure itself may require more time and skill from the dentist. Silver fillings, on the other hand, are more affordable.
The color of fillings has evolved over time, and white fillings are now a popular choice for many dental patients. They provide a natural appearance, bond to the tooth structure, and are mercury-free. However, silver fillings still have their advantages in terms of durability and cost-effectiveness. Ultimately, the choice between white fillings and silver fillings may depend on various factors, including the location of the cavity, personal preferences, and the dentist’s recommendation.
