Types of Dental Fillings

Types of Dental Fillings

Choosing the right filling material requires thoughtful consideration, as it significantly impacts the lifespan of your filling. When deciding which material your dentist should use for your filling, it’s essential to consider the following factors:

  • The appearance of the material and whether the filling will be visible.
  • The durability and strength of the material.
  • The expected longevity or lifespan of the filling.
  • The cost associated with the chosen material.

These considerations will help you make an informed decision that aligns with your dental needs, aesthetic preferences, and budget.

Composite Fillings

Composite fillings are tooth-colored materials composed of fine glass and plastic particles combined together. One advantage is that we can match this filling to your enamel so that it seems natural when you smile. A composite filling is also very durable and lasts 10 to 12 years.

Metal Fillings

Metal fillings include amalgam gold or silver. Gold is 10 times more durable than silver amalgam, yet both are extremely durable. A metal filling lasts ten to fifteen years and is more durable than a composite filling.

Ceramic Fillings

Compared to composite fillings, ceramic fillings are more stain-resistant, tooth-colored, and made of porcelain. Ceramic cavity fillings are strong, almost as costly as gold fillings, and often last for more than 15 years.

Glass Ionomer Fillings

Glass ionomer fillings are a blend of acrylic and glass that releases fluoride to help protect teeth. Compared to other fillers, glass ionomer fillings are less strong. Usually, they are applied to little cavities that are close to the gum line. and can require replacement in as short as five years.

When Should Fillings Be Replaced?

When Should Fillings Be Replaced?

You might be fortunate enough to never require a filling replacement, but chances are that at some point in your life, a filling could crack or wear down, no longer effectively shielding the tooth from decay. In some instances, a filling might simply dislodge and require replacement.
Initially, you may not notice when a filling begins to have issues, but your dentist is trained to identify potential problems early on during regular checkups. Using a tool called an explorer, your dentist will probe around the edges of the filling to ensure it remains tightly sealed to the tooth and to detect any areas where bacteria could penetrate, leading to further decay.
Dental X-rays can also uncover decay beneath the filling or in nearby areas. If it appears that the filling is no longer preventing bacteria from entering and supporting the tooth, it’s time for a replacement.
Additionally, a sore or sensitive tooth could signal the need for filling replacement, but it’s advisable not to wait until symptoms arise before having your fillings routinely examined.

Taking Care of a Tooth Filling

Taking Care of a Tooth Filling

Taking care of a tooth filling is important to ensure its longevity and your oral health. Here are some key tips:

  • Always use fluoride toothpaste while brushing twice a day, and floss every day.
  • Limit sweet, sticky foods and choose more nutritious options instead.
  • To reduce oral bacteria, rinse with a therapeutic mouth rinse free of alcohol.
  • Avoid tobacco products and limit meals that may cause stains on your fillings. Start making it a habit to rinse your mouth with water when you do eat these foods.
  • Choose water over acidic drinks such as juices and sodas.
  • Do not chew ice or bite down on hard foods.
  • For cleanings and checkups, see a dentist at least once a year, and more frequently if your dentist suggests it.


In conclusion, the longevity of dental fillings is influenced by various factors such as the type of material used, oral hygiene practices, and individual habits. While fillings can last for several years with proper care, it’s essential to stay proactive in maintaining oral health. Regular visits to a trusted dental clinic like Enhance Dental Centre can provide personalized guidance and timely interventions to ensure the durability of your dental work.

1- How often do fillings need to be replaced?

Dental fillings don’t last forever and need replacement due to wear and tear. The lifespan varies depending on the filling type, with composite fillings lasting 7-10 years and silver amalgam fillings lasting 10-15 years. However, this can be impacted by factors like oral hygiene and clenching habits, so regular dental checkups are key to monitoring their condition.

2- How do I know if my filling needs replacing?

You may need to replace a dental filling if you experience any of the following signs: persistent pain or sensitivity in the tooth, visible cracks or wear on the filling, a broken or chipped filling, or if the filling appears to be discolored or stained. Additionally, if you notice rough edges on the filling or if food gets stuck around it frequently, these can be indicators that the filling needs to be examined and potentially replaced by your dentist. Regular dental check-ups can help catch these issues early.
