No one wants cavities, but when one happens, quick and decisive action can ensure that as much of your natural tooth as possible is preserved. Depending on the size and severity of decay, the dentist will most likely recommend a filling. You now have two options – amalgam, or composite resin. But how do you know which one to take? Do you simply take the dentist’s recommendation, or is this worth further consideration?
We’ll discuss the pros and cons of both options so that you can get a better idea of which one would be right for you.
Amalgam vs. Composite: What’s the difference?
Amalgam fillings are made of a mix of metals. They are darkly colored, and are what comes to mind when most people think of fillings. Composite fillings use a composite resin that is shade-matched to tooth enamel. Both are used to fill in spaces left after decayed enamel has been removed, but there are key differences in how they are applied. Also, amalgam fillings have been used for more than a century, while composite resin fillings first came into public use in the 1960’s.
Amalgam Fillings: Pros and Cons
The long history of amalgam fillings has allowed for them to be tested and refined over many years. They are considered the more durable option, able to withstand a decade or better without wearing or becoming dislodged. They are also self-sealing, providing effective protection against decay.
On the downside, amalgam fillings are fairly noticeable due to the dramatic difference in color from tooth enamel. There are also questions about the safety of amalgam use due to the presence of mercury, which is used to bond the other metals together. Reports of allergy to amalgam fillings is rare, but the concern has led to a decrease in the use of amalgam over composite fillings.
Composite Fillings: Pros and Cons
One of the biggest reasons for the spike in popularity of composite fillings is that they are nearly invisible to the naked eye. The material is shade-matched to the tooth, allowing it to blend into the surrounding enamel. Moreover, it is highly malleable; it adheres well to the enamel, which means it requires less removal of the enamel for placement.
Composite fillings do have their limitations. They are currently not as durable as amalgam fillings, and while they now last a decade or more on average, they are still comparatively weaker. It is important to note, however, that composite material is continuously being updated, and the lifespan of these fillings is expected to continue improving.
