Key Points

  • Innovations in composition and dental techniques have made white fillings a popular alternative to traditional, amalgam fillings.
  • That is because they offer many advantages, including their superior appearance, without sacrificing durability. 
  • Understanding how white fillings work and the many benefits they afford can help patients determine if this option is right for them. 

According to the National Institutes of Health, approximately 90 percent of all adults ages 20 to 64 in the United States have had decay in their teeth.1 If you are among these, you have probably faced the decision of what type of filling material to choose.

At LoRen Dental, we understand that modern patients want restorations that not only restore function but also maintain the natural beauty of their smile.
That is where white fillings come in.

Unlike the metallic amalgam fillings of the past, these advanced materials blend seamlessly with your natural tooth structure, providing both durability and aesthetic appeal. They have become the gold standard in dental restoration and have even become popular as a replacement for older restorations.

This article covers everything you need to know about white fillings. Keep reading to find out if they might be the best option for you.

What Are White Fillings and How Do They Work?

White fillings, sometimes called “tooth-colored fillings,” are made from composite resin, a durable plastic material mixed with fine glass or ceramic particles.2 This combination creates a strong, natural-looking restoration that bonds directly to your tooth structure. The process involves removing the decayed portion of the tooth, preparing the surface, and then carefully layering and sculpting the composite material to restore the tooth’s original shape and function.

The composite resin used in modern white fillings teeth restorations has evolved significantly over the past few decades. Today’s materials are stronger, more stain-resistant, and more durable than ever before. They are designed to withstand the daily forces of chewing while maintaining their appearance for many years.

The Advantages of Choosing White Fillings

When patients visit our dental office, they often ask about the benefits of choosing dental white fillings over traditional options. There are many to consider:filling

Aesthetic Appeal

The most obvious advantage of white fillings is cosmetic. White fillings can be precisely color-matched to your natural tooth shade, making them virtually invisible.

This is particularly important for fillings in visible areas like your front teeth or when you smile widely. You can laugh, talk, and eat with confidence, knowing that your dental work is not on display.

Conservative Tooth Preparation

White fillings require less removal of healthy tooth structure compared to amalgam fillings. The composite material bonds directly to your tooth, which means your Raleigh dentist can preserve more of your natural tooth. This conservative approach helps maintain the long-term strength and integrity of your tooth.

Reduced Sensitivity

Metal fillings can conduct temperature changes, leading to tooth sensitivity when consuming hot or cold foods and beverages. Composite resin acts as an insulator, significantly reducing temperature-related discomfort.

Immediate Results

White fillings harden instantly under a special curing light, which means you can eat and drink immediately after your appointment without worrying about biting down on the restoration while it sets.

Mercury-Free Solution

For patients concerned about mercury exposure, white fillings offer complete peace of mind.3 They contain no metals whatsoever, eliminating any concerns about potential mercury-related health effects.

White Fillings vs Silver: Understanding Your Options

The white fillings vs amalgam debate is one that many patients face when they need dental restoration. While both materials have their place in dentistry, understanding the key differences can help you make the best choice for your situation.

Appearance and Aesthetics

Silver amalgam fillings are highly visible and can darken over time, making them even more noticeable. They can also cause a grayish discoloration in the surrounding tooth structure. White fillings, on the other hand, maintain their natural appearance and do not affect the color of your teeth.

Material Properties

Amalgam fillings expand and contract with temperature changes more dramatically than tooth structure, which can eventually lead to cracks in the tooth. Composite resin has thermal expansion properties closer to natural tooth structure, reducing this risk.

Placement Technique

Silver fillings require mechanical retention, meaning the tooth must be shaped in a specific way to hold the filling in place, often requiring removal of healthy tooth structure. White fillings bond chemically to tooth structure, allowing for more conservative preparations.

Longevity Considerations

While amalgam fillings have traditionally been considered more durable for large restorations in back teeth, advances in composite technology have largely closed this gap. Today’s white fillings are remarkably strong and can last many years with proper care.

How Long Do White Fillings Last?

The lifespan of white fillings depends on several factors, but you can generally expect them to last between seven and 15 years (or even longer) with proper care.

Several factors influence the longevity of your white fillings:

  • Size and location of the filling: Smaller fillings in areas that do not bear heavy chewing forces typically last longer.
  • Oral hygiene habits: Regular brushing, flossing, and professional cleanings help extend the life of all dental work, including white fillings.
  • Dietary habits: Limiting sugary foods and beverages reduces the risk of new decay around the filling.
  • Teeth grinding: If you grind or clench your teeth, this can impact the lifespan of white fillings. However, a custom night guard can protect your fillings from excessive wear.
  • Quality of placement: Choosing an experienced Raleigh dentist who uses high-quality materials and proper technique is crucial.
  • Follow-up care: Regular dental checkups allow your dentist to monitor your fillings and address any issues early.

With advances in bonding agents and composite materials, many patients find that their white fillings last as long as or longer than traditional amalgam fillings, especially when they maintain good oral hygiene and visit their dentist regularly for preventive care.

The White Filling Procedure: What to Expect

Understanding the procedure can help alleviate any dental anxiety about getting white fillings. At our Raleigh dental practice, we prioritize patient comfort and take time to explain each step of the process.

First, your dentist will numb the area around the tooth to ensure you are completely comfortable. Once the anesthesia takes effect, the decayed portion of the tooth is carefully removed using specialized instruments. The tooth is then thoroughly cleaned and prepared for the filling material.

For white fillings, the tooth surface is treated with a special bonding agent that helps the composite material adhere securely. The composite resin is then applied in layers, with each layer being hardened using a curing light. This layering technique allows your dentist to achieve the most natural appearance and optimal strength.

After the filling is placed, your dentist will carefully shape and polish it to ensure it fits comfortably with your bite and looks natural. The entire procedure typically takes 30 minutes to one hour, depending on the size and location of the filling.

Cost of White Fillings

The cost of white fillings is often a consideration for patients planning their dental care. While white fillings may sometimes cost slightly more than traditional amalgam fillings, many patients find the benefits well worth the investment.

Several factors affect the cost:

  • Size of the cavity: Larger dental fillings require more material and time to place, which impacts the cost.
  • Number of tooth surfaces involved: Fillings are often priced based on how many surfaces of the tooth are affected.
  • Location of the tooth: Molars can be more challenging to access and restore than front teeth, making the procedure more difficult and time-consuming.
  • Insurance coverage: Many dental insurance plans now cover white fillings at the same rate as amalgam, especially for front teeth.

At LoRen Dental, we believe that quality dental care should be accessible. We work with most insurance providers and offer flexible payment options to help make your dental restoration affordable. During your consultation, our team will provide a detailed cost estimate and discuss your payment options.

Caring for Your White Fillings

Maintaining your white fillings is straightforward and follows the same principles as caring for your natural teeth. Here are some tips to help your restorations last as long as possible:

  • Brush twice daily with fluoride toothpaste and a soft-bristled toothbrush.
  • Floss daily to remove plaque from between teeth and around fillings.
  • Visit your Raleigh dentist office every six months for checkups and professional cleanings.
  • Limit sugary and acidic foods that can contribute to new decay.
  • Avoid using your teeth as tools to open packages or bite non-food items.
  • Wear a night guard if you grind or clench your teeth.
  • Contact your dentist promptly if you notice any changes in your filling, such as sensitivity or roughness.

When to Consider Replacing Old Silver Fillings

Many patients visit our dental offices and ask about replacing their old amalgam fillings with white composite restorations. While amalgam fillings can last for many years, there are several situations where replacement might be recommended.

If your silver filling is cracked, worn, or showing signs of deterioration, replacing it can prevent bacteria from entering and causing new decay.  Additionally, if the tooth structure around the filling has become weakened or damaged, you might consider replacement with a white filling (and possibly a crown for added protection).

Some patients simply prefer the aesthetic improvement that comes with replacing visible metal fillings with tooth-colored restorations. This is a personal choice that can significantly enhance your smile’s appearance, especially if you have multiple visible metal fillings.
