What are dental fillings?

They work by filling the cavities or holes in your teeth, preventing further decay and restoring their natural shape and function. While there are various materials available for dental fillings, the most commonly used options include amalgam, composite resin, porcelain, and gold.

  • Amalgam Fillings
    Amalgam fillings, often referred to as silver fillings, are made of a combination of metals, including silver, mercury, tin, and copper. Despite containing mercury, they are considered safe for use in dental fillings as the mercury is bound within the mixture. Amalgam fillings are known for their durability and can last for up to 10 to 15 years, making them a cost-effective choice for many patients.
  • Composite Resin Fillings
    Composite resin fillings are tooth-colored fillings that are made of a blend of plastic and glass materials. They are an aesthetically pleasing option as they can be matched to the natural color of your teeth, making them virtually invisible. While composite resin fillings are not as durable as amalgam fillings, with proper care and maintenance, they can last for approximately 7 to 10 years.
  • Porcelain Fillings
    Porcelain fillings, also known as inlays or onlays, are custom-made restorations created in a dental laboratory. They are highly durable and stain-resistant, making them a popular choice for patients seeking long-lasting and natural-looking results. Porcelain fillings can last for 10 to 15 years or more, depending on your oral hygiene practices.
  • Gold Fillings
    Gold fillings are made of a mixture of gold, copper, and other metals. They are renowned for their longevity and strength. Gold fillings are highly resistant to wear and tear and can last for 15 years or longer. However, due to their noticeable appearance, they are often chosen for less visible areas of the mouth.

Don’t forget that the lifespan of dental fillings can vary depending on several factors. Some key factors that influence the durability of dental fillings include:

  • Oral Hygiene: Maintaining good oral hygiene practices, such as regular brushing, flossing, and routine dental check-ups, can significantly extend the lifespan of your dental fillings.
  • Bite Force: Individuals with heavy or uneven bite forces may experience more wear and tear on their fillings, potentially reducing their longevity.
  • Dietary Habits: Consuming excessive sugary foods and drinks can increase the risk of tooth decay and compromise the integrity of dental fillings.
  • Teeth Grinding (Bruxism): Teeth grinding can exert excessive pressure on dental fillings, leading to cracks or premature failure.
