Composite Dental Fillings: What are they and when are they used?

Almost everyone develops a cavity requiring a dental filling eventually. Despite how common they are, some people may not know much about the options available. Here, our Calgary dentists share some information about composite fillings, one of the most popular types used in dentistry.


What is a composite filling?

When you develop a cavity, your dentist will remove the decay from your tooth and use a filling to cover or 'fill' the area where the decayed material was.

Traditionally, fillings were a silver-coloured material, known as amalgam, that were quite visible in contrast to the shade of a natural tooth. Over time, other options were developed, one of which was composite.

Composite fillings are a tooth-coloured mix of plastic and ceramic, making them an excellent option for teeth that are exposed or visible when you talk or smile.

When are they used?

Composite fillings are effective for repairing chipped or cracked teeth because they blend in with your tooth, giving you a natural look.

Tooth areas that sustain heavy use, such as the chewing surfaces of molars, are typically not good candidates for a composite filling.

Some dental plans won't cover the cost of composite in these areas due to their reduced strength in comparison to amalgam. Speak with your dentist to determine which type best suits your needs.

The Benefits of Composite

  • Composite fillings blend seamlessly with your natural teeth, making them virtually invisible. 
  • The material is slightly flexible resulting in reduced drilling, and preserving more of your natural tooth.
  • The resin material in composite fillings creates a strong bond to your tooth.
  • They are durable and can withstand moderate pressure and usage.
  • They are well-suited to small fillings and repairs.
  • Composite can also be used to handle other cosmetic alterations, such as changing the colour or shape of your teeth.
