White Fillings

If you have a cavity, you might need to get a filling. Amalgam fillings used to be the most popular option, but nowadays, white fillings are becoming increasingly common. Amalgam fillings were usually made of silver or other materials that were visible when you opened your mouth. White fillings can match the color of your natural teeth for a more natural look, making them a popular choice for many people. In this blog post, we will discuss white fillings in more detail and why they are a great alternative to traditional amalgam fillings.

What are White Fillings?

White fillings, also known as tooth-colored fillings, are a type of dental filling designed to match the color of your natural teeth. This makes them virtually invisible and gives you a more aesthetic smile compared to amalgam fillings. They are used to restore the appearance and function of teeth damaged by decay or trauma.


There are several types of white fillings available, including:

  • Composite resin: This is the most common type of white filling. It is made of a mixture of glass and plastic and can be matched to the color of your teeth.
  • Glass ionomer: These fillings are made from a combination of acrylic and glass powders. They release fluoride, which can help prevent tooth decay.
  • Porcelain: These fillings are made from ceramic and are the most durable option. They are resistant to staining and can last longer than composite resin and glass ionomer.

Benefits of White Fillings

There are many advantages to choosing white fillings over amalgam fillings. These include:

  • Aesthetic appeal: As mentioned earlier, white fillings can blend in with your natural teeth, making them less noticeable when you smile or speak. This is especially beneficial for fillings in the front teeth, which are more visible.
  • Bonding with the tooth: Unlike amalgam fillings that rely on mechanical retention, white fillings bond directly with the tooth structure. This creates a stronger and more durable bond, reducing the risk of future damage or decay.
  • Minimally invasive: Tooth-colored fillings require less drilling and removal of healthy tooth structures compared to amalgam fillings. This means that the overall strength and integrity of the tooth are preserved, leading to better long-term outcomes.
  • No mercury: One of the biggest concerns with amalgam fillings is the use of mercury, a toxic substance. Tooth-colored fillings are completely free from mercury, making them a safer and healthier option for dental restorations.
  • Can be repaired: In case of damage or wear over time, white fillings can be easily repaired without having to replace the entire filling. This is not possible with amalgam fillings, which need to be completely removed and replaced.
  • Cures quickly: White fillings harden through a chemical process, allowing them to cure quickly. This means you can resume normal activities like eating and drinking soon after the procedure.

How are White Fillings Placed?

The process of getting white fillings is similar to amalgam fillings, with a few key differences. Here are the general steps involved:

  • Numbing: Just like with any other dental procedure, your dentist will first numb the area around the affected tooth using a local anesthetic.
  • Removal of decay: Your dentist will then use a drill or other instruments to remove any decayed parts of the tooth.
  • Etching: Next, your dentist will etch the surface of the tooth using an acidic gel. This creates tiny pores on the surface of the tooth that allow the filling material to bond properly.
  • Bonding: A bonding agent is applied to the prepared tooth before filling it, ensuring a strong bond between the filling material and the tooth.
  • Filling placement: The white filling material will then be placed in layers and hardened using a special light or chemical process.
  • Shaping and polishing: Once the filling is hardened, your dentist will shape it to fit your bite and polish it for a smooth finish.

Are There Any Disadvantages to White Fillings?

While white fillings have many advantages, there are also a few potential disadvantages that patients should be aware of. These include:

  • Sensitivity: Some patients may experience sensitivity to hot and cold temperatures after getting a white filling. This is temporary and usually resolves within a few days. However, if the sensitivity persists, it’s important to consult your dentist.
  • Staining: White fillings can stain over time, especially if you consume staining foods and drinks like coffee, tea, or red wine. Regular dental cleaning can help remove any surface stains that may occur.
  • Durability: Composite and glass ionomer fillings are not as durable as amalgam fillings. They may need to be replaced more frequently, especially if they’re placed on high-pressure areas like molars. Porcelain fillings, on the other hand, are highly durable and can last for many years.
  • Cost: White fillings are typically more expensive than amalgam fillings due to the materials and technique used. However, many patients find the aesthetic benefits well worth the extra cost. Porcelain fillings are the most expensive but also offer the best aesthetic result.

How Long Do White Fillings Last?

The lifespan of a white filling depends on various factors, such as the type of material used, the size and location of the filling, and your oral hygiene habits. On average, composite fillings can last 5-7 years, while glass ionomer fillings can last up to 5 years. Porcelain fillings, being the most durable, can last for over 10 years with proper care.

How Do I Care for My Dental Fillings?

White fillings can last for many years with proper care and maintenance. Here are some tips to help you take care of your white fillings:

  • Practice good oral hygiene: Brush your teeth at least twice a day and floss daily to prevent plaque buildup, which can lead to decay and damage to your fillings.
  • Avoid foods that can stain: tooth-colored fillings can become discolored over time if you consume too many dark-colored foods and drinks. Limit your intake of coffee, tea, red wine, and other stain-causing foods.
  • Wear a mouthguard: If you grind or clench your teeth while sleeping, wear a custom-made mouthguard to protect your fillings from damage.
  • Visit your dentist regularly: Regular dental check-ups and cleanings will help your dentist monitor the condition of your white fillings and detect any potential issues early on.
  • Follow a tooth-friendly diet: Limit your consumption of sugary and acidic foods to prevent damage to your fillings and natural teeth.
  • Be gentle with your fillings: Avoid biting down on hard objects, such as ice or pens, as this can cause your tooth-colored fillings to chip or crack.

In addition to these aftercare tips, it’s important to note that white fillings may need to be replaced eventually. They are not as durable as metal fillings and may wear down over time. If you experience any pain or sensitivity in the area of your filling, visit your dentist for an evaluation. Your dentist may recommend replacing the filling if it is damaged or worn down.


White fillings are a popular and effective choice for restoring damaged or decayed teeth. They offer several advantages over traditional amalgam fillings, such as a natural appearance and minimal removal of healthy tooth structure, making them a popular choice among patients.

By taking proper care of your white fillings and maintaining good oral hygiene habits, you can ensure their longevity and keep your smile looking bright and healthy. If you have any concerns or questions about tooth-colored fillings, don’t hesitate to consult with your dentist for personalized advice and guidance.
