How long do fillings last?
Dental fillings are a common treatment for cavities and tooth decay. The lifespan of a filling can vary depending on several factors, including the type of material used, the location of the filling in the mouth, and how well the individual takes care of their oral health.
On average, dental fillings can last anywhere from 5 to 15 years. Amalgam fillings, which are made of a mixture of metals, tend to last longer than composite fillings, which are tooth-coloured and more aesthetically pleasing. However, composite fillings are becoming increasingly popular due to their natural appearance.
The location of the filling can also play a role in how long it lasts. Fillings on the back teeth, where more pressure is placed during chewing, may wear down faster than fillings on the front teeth. Additionally, individuals who grind or clench their teeth may experience a shorter lifespan of their fillings.
Types of fillings:
Amalgam fillings
Amalgam fillings, also known as silver fillings, have been used in dentistry for over 150 years. They are a durable and cost-effective option for filling cavities in teeth.
The lifespan of an amalgam filling can vary depending on several factors, including the size and location of the filling, how well it was placed by the dentist, and the individual’s oral hygiene habits . On average, amalgam fillings can last anywhere from 10 to 15 years.
Composite
Composite fillings typically last between 5 to 10 years, depending on a variety of factors such as oral hygiene practices, the location and size of the filling, and the individual’s overall dental health.
Composite fillings are made of a tooth-coloured resin material that bonds to the tooth, providing a more natural appearance than traditional silver amalgam fillings. While composite fillings are durable and can withstand normal biting and chewing forces, they may be more prone to wear and tear over time compared to amalgam fillings.
Gold fillings
Gold fillings are known for their durability and longevity. On average, a gold filling can last anywhere from 15 to 30 years, or even longer with proper care and maintenance. This is significantly longer than other types of fillings, such as amalgam or composite resin, which typically last around 10 to 15 years.
One of the main reasons why gold fillings are so long-lasting is because gold is a very strong and stable material that can withstand the forces of chewing and biting without wearing down.
Ceramic and glass ionomer fillings
Ceramic and glass ionomer fillings are two popular options for dental fillings that offer different benefits and longevity.
Ceramic fillings, also known as porcelain fillings, are made of a durable material that closely resembles natural tooth enamel. These fillings are highly resistant to staining and can last for many years with proper care. In fact, ceramic fillings can last anywhere from 10 to 15 years or longer.
Glass ionomer fillings are a more affordable option that releases fluoride, which can help prevent further decay in the tooth. These fillings typically last around 5 to 7 years, but with proper care and regular dental check-ups, they can last longer.
Can my diet affect how long fillings last?
A diet high in sugary and acidic foods can contribute to the decay of teeth and the breakdown of fillings. Sugary foods provide fuel for bacteria in the mouth, which can lead to cavities forming around the edges of the filling. Acidic foods and beverages can also weaken the structure of the filling over time.
To help prolong the lifespan of your fillings, it is important to maintain a balanced diet that is low in sugary and acidic foods. Additionally, practicing good oral hygiene habits such as brushing and flossing regularly, visiting the dentist for regular check-ups and cleanings, and avoiding habits like teeth grinding can help extend the longevity of your fillings.
In conclusion, the lifespan of a filling can vary depending on the type of filling material used, the location and size of the filling, oral hygiene practices, diet, and individual factors such as teeth grinding.
