What are tooth fillings?
Tooth fillings are dental material that dentists use to fill up a cavity on a tooth to restore their appearance and functionality. Since cavities are a common dental problem, it is estimated that at least 90% of adults have at least one filling in their lifetime. However, fillings are not only used to treat cavities, but can also be applied in tooth injury cases such as chipping or cracking.
Types of fillings
There are many types of fillings, but not every type of filling is ideal for everyone. Here are some of the most common types of tooth fillings.
Amalgam fillings
These are the most common types of fillings and the most affordable option for fillings. Amalgam fillings are the silver that you will typically see most adults or children with. Amalgam fillings are mostly applied on the back teeth because of their visibility. The silver material can easily be seen, and it is only reasonable to have them on the back teeth where they will not be exposed. Besides being the most affordable type of fillings, amalgam fillings are known to last longer than most fillings and can take more than a decade before needing any replacement.
Composite fillings
Composite fillings are tooth-coloured fillings that chemically bond to the tooth structure for more stability. More and more patients are nowadays opting for composite fillings because of their aesthetic appeal. Compared to amalgam fillings, composite fillings give a more natural look to teeth and are therefore more preferred. In fact, some patients are even choosing to have their amalgam fillings replaced with composite fillings instead. One disadvantage of composite fillings, however, is the fact that they are not as durable as amalgam fillings and will therefore need replacement after some time. They may also be susceptible to breakage or damage as well.
Gold tooth fillings
As the name suggests, gold tooth fillings are made of gold, and for this reason, they make one of the most durable fillings around. However, just like gold jewellery, gold fillings are super expensive compared to other types of fillings. They are also quite visible, like amalgam fillings. However, for patients who prefer to have the gold aesthetic on their teeth, this may be the best filling option.
Ceramic fillings
Ceramic tooth fillings are made from porcelain material and are also very expensive, even more than gold. They are, however, very durable and can last over 15 years if well taken care of.
Glass Ionomer fillings
These fillings are made of a combination of glass and acrylic material. This makes it a very weak filling and may not be recommended for filling tooth surfaces that are used for chewing or biting, such as molars and incisors. Therefore, dentists like to use glass ionomer for fillings below the gum line. One interesting fact about glass ionomer fillings is the fact they release fluoride over time, which helps in strengthening the tooth structure around the filling.
