What Makes Composite Resin Fillings the Preferred Option for Minor Cavities

Composite resin fillings are also known as tooth-colored or white fillings. These are a relatively new type of dental filling procedure that has gained popularity over the years. These fillings are made of a mixture of plastic and glass materials, which can be color-matched to blend in with your natural teeth.

Traditional amalgam (silver) fillings have been used for decades. However, composite resin fillings offer several advantages that make them the preferred option for treating minor cavities.

Advantages of Composite Resin Fillings

Composite resin fillings have become the preferred option for minor cavities. This is due to the following advantages of this type of composite tooth filling:


One of the main reasons why composite resin fillings are preferred over amalgam fillings is their aesthetic appeal. As mentioned earlier, these fillings can be color-matched to blend in with your natural teeth.

This makes them virtually invisible. So, it means that you can have a cavity filled without anyone even noticing.

On the other hand, amalgam fillings are made of a silver-colored material that can be easily seen when you open your mouth. This may not be a big concern for back teeth, but it can be noticeable and unattractive for front teeth.


Composite resin fillings can bond directly to the tooth structure. This creates a strong seal that helps to prevent further decay.

This bonding process also allows for more conservative treatment. This is because less of the healthy tooth structure needs to be removed to place the filling.

On the other hand, amalgam fillings require more removal of healthy tooth structure because they do not bond directly to the tooth. This can weaken the overall structure of the tooth and may lead to fractures or cracks over time.


Composite resin fillings can be used to treat not just cavities. It can also chipped, cracked, or worn teeth.

They can even be used for cosmetic purposes. This includes filling in gaps between teeth or reshaping uneven edges.

This versatility makes them a preferred option for minor dental issues and allows for more conservative treatment options.


Composite resin fillings are known for their durability. With proper care and maintenance, they can last for several years.

They are also less likely to cause sensitivity to hot or cold temperatures. This is a common complaint with amalgam fillings due to their metal composition. However, it’s important to note that composite resin fillings may not be as durable as amalgam fillings for larger cavities or those located in areas with a lot of chewing force.

Reduced Sensitivity

As mentioned earlier, amalgam fillings can cause sensitivity to hot and cold temperatures. This is because they are good conductors of heat and cold.

On the other hand, composite resin fillings do not conduct temperature as well. This can help reduce or eliminate any sensitivity experienced after getting a filling.


Another advantage of composite resin fillings is their biocompatibility. Amalgam fillings contain mercury, which can be a concern for some individuals.

Composite resin fillings do not contain any harmful materials. They are also considered safe for use in dental restorations.


If a composite resin filling is damaged or worn down over time, it can easily be repaired without having to replace the entire filling.

This makes them a more cost-effective option in the long run compared to amalgam fillings. This would need to be completely replaced if damaged.


While composite resin fillings have many advantages, they may not be suitable for everyone. Here are some of the factors to consider before choosing this type of filling:

Size and Location of the Cavity

Composite resin fillings are best suited for smaller cavities. If the cavity is too large, it may not be able to withstand the chewing forces and may eventually fail.

They are also not recommended for areas with a lot of chewing force, such as molars. Amalgam fillings may be a better option in these cases.


Composite resin fillings can be more expensive compared to amalgam fillings. This is because the materials used are more costly and they require a high level of skill and technique to place.

However, considering the aesthetic appeal and long-term durability, many individuals find them worth the investment. Some dental insurance plans may also cover the cost of composite resin fillings.


The placement of composite resin fillings can be more time-consuming compared to amalgam fillings. This is because the filling material needs to be applied in layers and each layer needs to be hardened with a special light.

This may not be a concern for smaller cavities, but for larger ones, multiple appointments may be needed to complete the filling.

Bite Force and Chewing Habits

As mentioned earlier, composite resin fillings may not be suitable for areas with a lot of chewing force. This is because they are not as strong as amalgam fillings.

Additionally, individuals with habits such as teeth grinding can put extra stress on the filling. This may cause it to fail over time.

Oral Hygiene Habits

Composite resin fillings, like natural teeth, require proper oral hygiene to maintain their longevity. This includes regular brushing, flossing, and dental cleanings. If an individual has poor oral hygiene habits, they may be more prone to tooth decay and the filling may not last as long.

Allergies or Sensitivities

While composite resin fillings are considered safe for most individuals, some may have allergies or sensitivities to the materials used. It’s important to discuss any known allergies with your dentist before getting a filling.

Insurance Coverage

It’s important to check with your dental insurance provider to see if they cover composite resin fillings. Some plans may only cover amalgam fillings or may have a limit on the amount covered for tooth-colored fillings.

Dentist’s Recommendation

Ultimately, the decision to choose composite resin fillings over amalgam fillings should be made in consultation with your dentist. They can assess your situation and make a recommendation based on their professional expertise. So, if you have minor cavities that need to be filled, consult with a dentist from your area such as this Gahanna dentist to see if composite resin fillings are the right option for you.
