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

Most people will eventually develop a cavity that requires a dental filling. However, many are unaware of the available options. That's why our team of dentists at Sydney is here to guide you.

What is a composite filling?

When you have a cavity, your dentist will remove the decayed portion and use a filling to cover the area. Silver-colored amalgam fillings were commonly used in the past, but now we have composite fillings.

Composite fillings are made of a tooth-colored mixture of plastic and ceramic. They are an excellent choice for visible teeth when you smile or speak.

When are they used?

If you have chipped or cracked teeth, composite fillings are a great option because they blend in seamlessly with your natural tooth color.

However, composite fillings may not be the best choice for heavily used areas like molars due to their reduced strength compared to amalgam fillings.

It's essential to discuss your specific needs with your dentist to determine the most suitable type.

Why Composite Fillings?

  • Composite fillings blend 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 with 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.

How Long Do Composite Fillings Last?

Composite fillings, while durable, tend to have a shorter life span than other filling materials. They tend to last about 7 years. You might get 10 years out of a composite filling if the fillings are well taken care of through proper oral hygiene habits.

Are Composite Fillings Safe?

Composite dental filling has become increasingly popular and many dentists say that composite resin causes no health concern. Both composite filling and sealants are made of resin material, containing BPA which releases for some time in the mouth after filling replacement.

However, the dental community pointed out some significant facts. According to them, studies have failed to underline any conclusive results regarding the use of BPA in the resins as a harmful component.

In addition to that, they believe that composite resins use a negligible amount of Bis-GMA, which is not detrimental to the patients. They concluded health concerns regarding composite resins are baseless that and do not have substantial evidence to prove BPA as a threat to human health.
