The benefits of composite fillings: a guide for patients from our dentist

If you've ever had a cavity, you've probably had it filled with a material called a dental composite. But what exactly are composite fillings at our dentist in Orpington, and how do they compare to traditional options? In this article, we'll explore the benefits of composite fillings and why they may be the best choice for your dental health.

What are composite fillings?

Composite fillings, also known as tooth-coloured fillings, are made of a mixture of acrylic resin and fine glass particles. This combination creates a strong and durable material that can be easily moulded and shaped to match the natural colour and contours of your teeth.

One of the biggest advantages of composite fillings is their aesthetic appeal. Because they can be matched to the shade of your teeth, composite fillings are virtually undetectable once they are in place. This makes them a great choice for filling cavities in visible teeth, such as those in the front of your mouth.

In addition to their cosmetic benefits, composite fillings also have several practical advantages over traditional options.

Durability and longevity

Composite fillings are strong and long lasting, with many patients experiencing a lifespan of seven to ten years. This is due in part to the fact that composite fillings bond directly to the tooth structure, creating a stronger and more durable seal than traditional fillings.

Furthermore, composite fillings are resistant to wear and tear, making them a good choice for teeth that experience a lot of chewing pressure. This makes them an ideal option for filling cavities in molars and premolars, which are responsible for grinding and crushing food.

Minimal tooth preparation

Unlike traditional amalgam fillings, which require the removal of a significant amount of healthy tooth structure, composite fillings can be placed with minimal tooth preparation at our dentist in Orpington. This means that less of your natural tooth needs to be removed in order to place the filling, resulting in a stronger and healthier tooth overall.

Conservation of tooth structure

Because composite fillings require minimal tooth preparation, they are a more conservative option for repairing cavities. This means that more of your natural tooth structure is preserved, which is important for maintaining the strength and integrity of your teeth.

Ease of repair

Composite fillings can be easily repaired or replaced if they become damaged or wear down over time. This is because the filling material can be moulded and shaped to match the contours of your tooth. In addition, composite fillings can be repaired using a UV curing process, which involves using a UV light to harden the filling material. This quick and efficient method can help extend the life of the filling. In contrast, traditional amalgam fillings cannot be repaired and must be completely replaced if they become damaged or wear down. Overall, the ease of repair and the option to use UV curing make composite fillings a more convenient and long-lasting choice for filling cavities and repairing damaged teeth.


Composite fillings are a strong, durable, and aesthetically pleasing option for repairing cavities. They offer several advantages over traditional fillings, including the ability to match the colour of your teeth, minimal tooth preparation, and the ability to repair or replace the filling if necessary.
