The average lifespan of dental fillings can vary considerably depending on a number of factors, such the size of the filling, the material used, the forces the restoration is subjected to, and your home-care and professional care regimen.

Silver Fillings

Silver fillings, also known as amalgam fillings, are very strong and highly durable. On average, silver fillings can last between 10-15 years. Despite having a substantial lifespan, many patients prefer white fillings over amalgam fillings, as amalgam fillings can be highly visible and not as aesthetically pleasing. There is also a growing concern around the mercury levels that are associated with silver fillings.

White Fillings

White fillings, also known as composite fillings, are typically desired for their appearance, as they blend in well with the the surrounding tooth structure and can look very natural. The typical lifespan for white fillings is between 7-10 years, but they can even last up to 15 years as well.

These are some general parameters around the average longevity of fillings. The exact lifespan of your fillings, however, will depend on various other factors, such as your overall oral health and behavioural habits such as teeth grinding. The best way to ensure that your fillings are still in proper condition is to see your dental healthcare professional regularly
