How Dental Fillings Treat Cavities and Preserve Your Teeth

Cavities are one of the most common oral health issues, but thanks to modern dentistry, they’re also one of the easiest to treat.

At Holmes Dental, we’re proud to offer compassionate, expert care for patients in Fort Collins, CO, and surrounding communities, ensuring every smile stays strong and healthy.

Whether you’re dealing with a cavity or simply exploring restorative dentistry treatment options, understanding dental fillings, including different kinds of fillings, can help you make informed decisions about your oral health and dental care. In this guide, we’ll walk you through everything you need to know about dental fillings, from their purpose and types to the procedure and aftercare, so you can feel confident about your next visit to the dentist.

What Are Dental Fillings?

Dental fillings are a restorative treatment used to repair tooth fillings and teeth affected by cavities, minor cracks, or wear. There are various types of fillings used in this process. Cavities form when tooth enamel breaks down due to plaque buildup and bacterial activity, leaving holes or weakened areas in the tooth structure. If left untreated, cavities can grow larger and potentially infect the dental pulp, leading to pain, infection, or even tooth loss.

Fillings work by sealing these damaged areas, restoring the tooth’s shape, strength, and function. At Holmes Dental, you’ll receive personalized care with fillings tailored to meet your unique needs. Whether you’re seeking a durable solution or a natural-looking restoration, our team will help you choose the right option for your smile.

Types of Dental Fillings

When it comes to dental fillings, patients have several material options, each with its own benefits. Here’s a closer look at the most common types:

Amalgam Fillings

Amalgam fillings, often called silver fillings, are made from a blend of metals, including mercury, silver, tin, and copper. Known for their durability and affordability, dental filling materials like amalgam material have been used in dentistry for over a century.

Pros:

• Long-lasting (often over 10 years).
• Strong and resistant to wear.
• Cost-effective.

Cons:

• Noticeable metallic appearance.
• Concerns about mercury content (though deemed safe by the ADA).

Composite Fillings

Composite resin fillings and porcelain fillings are tooth-colored restorations made from a mixture of resin and glass particles created in a dental lab. They’re a popular choice for patients who want a natural-looking solution that blends seamlessly with their smile.

Pros:

• Aesthetic appeal – matches the color of your teeth.
• Versatile and suitable for both front and back teeth.
• Minimally invasive (requires less removal of tooth structure).

Cons:

• May wear down faster than other materials.
• Slightly higher cost compared to amalgam.

Gold Fillings

Gold fillings are crafted from gold alloy and are known for their exceptional longevity and strength. While not as common today, they’re still a reliable option for patients seeking premium durability.

Pros:

• Extremely durable (lasting 20+ years).
• Resistant to corrosion and wear.

Cons:

• Expensive.
• Noticeable metallic appearance.

Ceramic Fillings

Ceramic fillings are made from porcelain and offer a natural, tooth-like appearance. They’re often used for larger restorations or inlays and onlays.

Pros:

• Highly aesthetic – matches tooth color.
• Resistant to staining.

Cons:

• More brittle than other materials.
• Higher cost.

Glass Ionomer Fillings

Glass ionomer fillings are created from a blend of acrylic and glass. They’re often used for small cavities or in areas that don’t experience heavy chewing pressure, particularly in young children.

Pros:

• Releases fluoride to help protect against further decay.
• Ideal for pediatric patients or temporary solutions.

Cons:

• Less durable than other materials.
• Limited aesthetic appeal.

Choosing the right filling material depends on factors like the location of the cavity, your budget, and your aesthetic preferences. During your consultation at Holmes Dental, we’ll work with you to select the best option for your smile.

The Dental Filling Procedure

Initial Examination: Your dentist will begin by examining your teeth and identifying the area of decay. X-rays may be taken to determine the extent of the cavity, and to capture the shape of the tooth affected.

1. Initial Examination:
   Your dentist will begin by examining your teeth and identifying the area of decay. X-rays may be taken to determine the extent of the cavity.
2. Preparation: Once the cavity is identified, the area will be numbed with a local anesthetic to ensure your comfort throughout the procedure.
3. Decay Removal: Using specialized tools, your dentist will carefully remove the dental decay, along with the decayed portion of the tooth, taking into account the extent of the decay, leaving a clean, healthy surface for the filling.
4. Filling Placement: The chosen filling material is applied to the prepared area. For composite fillings, the material is placed in layers and hardened using a curing light, ensuring a strong final restoration.
5. Shaping and Polishing: Once the filling is in place, your dentist or a dental technician will shape it to match your bite and polish the surface for a smooth finish.

The entire process typically takes less than an hour, making dental fillings one of the quickest ways to restore your smile.

Benefits of Dental Fillings

Dental fillings offer numerous advantages, making them a cornerstone of restorative dentistry:

• Restores Tooth Function: Fillings repair damaged areas, allowing you to chew and speak comfortably.
• Prevents Further Tooth Decay: By sealing cavities, fillings stop bacteria from spreading deeper into the tooth.
• Improves Aesthetics: Tooth-colored fillings blend seamlessly with your natural teeth, especially enhancing the appearance of your front teeth and smile.
• Quick and Convenient: The procedure is fast, minimally invasive, and performed in a single visit.

At Holmes Dental, we prioritize both function and beauty, ensuring every filling contributes to your overall oral health and confidence.

Risks and Complications

While dental fillings are safe and effective, some patients, including pregnant women, may experience minor issues after the procedure. 

Common risks include:

• Tooth Sensitivity: Mild sensitivity to hot, cold, or pressure is normal and usually subsides within a few days.
• Pain or Discomfort: If the filling isn’t shaped correctly, it may affect your bite, causing discomfort.
• Allergic Reactions: Rarely, patients may be allergic to certain filling materials.

If you experience prolonged pain, sensitivity, or notice signs of a loose or cracked filling, contact Holmes Dental immediately. Our team is here to ensure your comfort and oral health.

Post-Treatment Care

Caring for your teeth after a filling is essential for maintaining both your restoration and overall oral health. 

Here are some tips:

• Avoid Hard Foods: Refrain from eating sticky or hard foods for the first 24 hours.
• Maintain Oral Hygiene: Brush and floss daily to prevent plaque buildup around the filling.
• Manage Sensitivity: Use toothpaste designed for sensitive teeth if needed.
• Schedule Regular Checkups: Routine dental exams help monitor the condition of your fillings and prevent future cavities.

With proper care, most fillings can last for many years, keeping your smile healthy and strong.

When to See a Dentist

It’s important to visit your dentist if you notice signs of a cavity or issues with an existing filling. 

Common symptoms include:

• Toothache or sensitivity.
• Visible holes or dark spots on the tooth.
• Cracks, pain, or loosening of a filling.

Addressing these concerns promptly can prevent further complications, saving you time and discomfort. At Holmes Dental, our friendly team is always here to provide expert care and guidance.
