How to Choose Between Different Types of Dental Fillings: A Guide from Hampstead Dental
Dental fillings play an important role in restoring tooth structure affected by decay or minor damage. There are several types of filling materials available, and the most suitable option may vary based on the location of the cavity, the extent of the damage, and your individual circumstances.
At Hampstead Dental, our clinicians aim to provide tailored advice to help you make an informed decision about the type of filling material that may be appropriate for your oral health needs.
Common Types of Dental Fillings
Each type of filling material has specific characteristics. Here’s an overview of some commonly used options:
Composite Resin Fillings
Composite resins are tooth-coloured materials that can blend in with natural tooth structure. They are typically used in areas where aesthetics are important, such as the front teeth.
Key points:
-
Designed to match tooth colour
-
Can bond directly to the tooth surface
-
Generally used for small to medium restorations
-
May stain or wear over time with use
Amalgam Fillings
Amalgam fillings contain a combination of metals, including silver, tin, copper, and mercury. They have been used in dentistry for many years and are often selected for their durability, particularly in back teeth.
Key points:
-
Known for strength and longevity
-
May be noticeable due to metallic colour
-
Some people may choose to avoid mercury-based materials
Glass Ionomer Fillings
This material consists of acrylic and glass particles and is often used in areas with less chewing pressure. It also releases small amounts of fluoride over time.
Key points:
-
Releases fluoride, which may help reduce the risk of decay
-
Generally suited for areas near the gumline or less visible parts of the mouth
-
May not be as long-lasting in high-stress areas
Resin Ionomer Fillings
This is a modified version of glass ionomer that includes resin, which can improve both strength and appearance.
Key points:
-
Provides fluoride release with enhanced durability
-
Suitable for low to moderate chewing forces
-
May still require replacement sooner than other materials
Factors That May Influence Your Choice
The decision regarding which filling material to use is based on several clinical and personal considerations:
-
Location of the Cavity
Fillings in front teeth may benefit from a more aesthetic material such as composite, while molars may require more durable options. -
Extent of the Decay or Damage
Deeper or wider cavities may require stronger materials to ensure longevity. -
Your Preferences
Some patients may prefer tooth-coloured materials for visual reasons, while others may prioritise durability or cost. -
Cost and Private Health Coverage
Different materials vary in cost, and some may be partially covered by private health insurance policies. -
Risk of Future Decay
Materials that release fluoride, such as glass ionomer, may be considered where there is an elevated risk of further decay.
