Fillings
Fillings are needed when teeth are contain caries, or have broken and fractured. The most common filling material is a composite resin (tooth colored). For fillings to be successful, some parts of your natural tooth structure are needed as all fillings are bonded to you existing tooth structure. Book a consultation or exam with one of our dentists to see if you may need any fillings.
Composite Resin
Composite resin is the most commonly used material for fillings. It is a tooth-coloured material that is used to fix broken or decayed teeth which adheres to the surface of the tooth though a process called bonding. As composite resin is bonded to the tooth’s surface, cavity design can be more conservative leaving a healthier tooth structure. Composite resin comes in a variety of colours, allowing our dentists to colour match the tooth being fixed.
Glass-ionomer cement
Glass-ionomer cement (GIC) is also a white or tooth-coloured filling material. The main advantage of a GIC is that it contains Fluoride which minimizes secondary decay developing around the margin of the filling. However, as it is not as strong as composite resin, it is not usually placed in high load bearing areas, limiting its applications.
Frequently Asked Questions
What is a dental filling, and why might I need one?
A dental filling is used to repair a tooth damaged by decay or minor fractures. It restores the tooth’s function, shape, and prevents further decay.
What are composite resin fillings?
Composite resin fillings are tooth-coloured fillings that blend naturally with your teeth. They are a popular choice for both front and back teeth because of their aesthetic appeal and durability.
What is glass-ionomer cement, and when is it used?
Glass-ionomer cement is a tooth-coloured material that releases fluoride, helping protect the tooth from further decay. It’s often used for fillings in areas with less biting pressure or for children’s teeth.
How long do dental fillings last?
The lifespan of a filling depends on the material and its location. Composite resin fillings typically last 5–7 years or longer with good care, while glass-ionomer fillings may have a shorter lifespan but offer added fluoride protection.
Will getting a filling hurt?
Most fillings are done under local anaesthetic, making the procedure comfortable and pain-free. You might feel slight sensitivity after the filling, but this usually settles quickly.
