In this blog, we’ll explore the most common types of teeth fillings, how they work, their pros and cons, and how to decide which one might be right for you.
1. Amalgam Fillings (Silver Fillings)
What Are They? Amalgam fillings are made from a mixture of metals, including silver, mercury, tin, and copper. These durable and affordable fillings have been used in dentistry for over 150 years.
Pros:
• Durable and Long-Lasting: Amalgam fillings are known for their strength and longevity, often lasting 10-15 years or longer with proper care.
• Cost-Effective: They are one of the most affordable filling options.
• Resistant to Wear and Tear: Amalgam fillings are highly resistant to pressure from chewing, making them ideal for back teeth where the force from biting and grinding is greatest.
Cons:
• Aesthetic Concerns: Amalgam fillings are dark in color, which makes them highly visible, especially in the front of the mouth. This can be a concern for people who want a more natural appearance.
• Mercury Content: Though the mercury in amalgam fillings is considered safe by the FDA and other health organizations, some people prefer to avoid mercury-containing products due to health concerns.
• Potential for Expansion: Over time, amalgam fillings may expand or contract due to temperature changes, which could cause the tooth to crack.
Best For: Amalgam fillings are typically used for molars and premolars, where the filling isn’t as visible and durability is more important than aesthetics.
2. Composite Fillings (Tooth-Colored Fillings)
What Are They? Composite fillings are made from a mixture of plastic resins and glass or quartz fillers, which allow them to blend seamlessly with your natural tooth color. These fillings are molded directly into the cavity and hardened with a special light.
Pros:
• Aesthetic Appeal: Composite fillings are designed to match the natural color of your teeth, making them ideal for front teeth or visible areas.
• Versatility: These fillings can be used for cavities of any size and in almost any area of the mouth.
• Bonding to Tooth Structure: Composite fillings chemically bond to the tooth, which provides additional strength and stability to the tooth structure.
Cons:
• Less Durable Than Amalgam: While composite fillings are strong, they are generally less durable than amalgam and may wear down or stain over time, especially in areas that undergo heavy chewing pressure.
• Cost: Composite fillings tend to be more expensive than amalgam fillings.
• Longer Procedure Time: The application of composite fillings requires more time, as the dentist must carefully layer the material and cure it in stages.
Best For: Composite fillings are excellent for front teeth or any area where appearance is important. They are also suitable for small to medium cavities.
3. Ceramic Fillings (Porcelain Fillings)
What Are They? Ceramic fillings are made from porcelain, which offers a highly durable and natural-looking solution for cavities. They are typically crafted in a dental laboratory and then bonded to the tooth in a later appointment.
Pros:
• Natural Look: Porcelain fillings are highly aesthetic and can be matched to the exact shade of your teeth, making them ideal for visible teeth.
• Stain-Resistant: Ceramic fillings are resistant to staining and discoloration, so they maintain their appearance over time.
• Durable: Porcelain is a very strong material, making it highly durable, and it’s more resistant to wear than composite fillings.
Cons:
• Cost: Ceramic fillings are among the most expensive options, due to the need for custom fabrication and the high-quality materials used.
• More Tooth Removal: To fit ceramic fillings, your dentist may need to remove more of your tooth structure compared to other filling types.
• Brittleness: While strong, ceramic fillings can be more brittle than other materials, and may crack or fracture under extreme pressure, especially if not properly placed.
Best For: Ceramic fillings are ideal for front teeth and visible areas of the mouth. They are particularly popular for patients who want both aesthetics and durability.
4. Gold Fillings
What Are They? Gold fillings are made from a mixture of gold, copper, and other metals. Like ceramic fillings, gold fillings are created in a lab and then placed in the cavity.
Pros:
• Durability: Gold fillings are extremely durable and can last 15-20 years or more, making them one of the longest-lasting filling materials.
• Biocompatibility: Gold is well-tolerated by the body and rarely causes allergic reactions.
• Wear Resistance: Gold fillings resist wear and tear very well, and they are less likely to expand or contract than amalgam.
Cons:
• Aesthetic Concerns: Gold fillings are highly visible, which may be a problem for people who want a more natural-looking filling, especially for front teeth.
• Cost: Gold fillings are one of the most expensive types of fillings due to the material and the labor-intensive process of fabrication.
• Longer Procedure: It usually requires two visits—one for creating an impression of the tooth and another for placing the final gold filling.
Best For: Gold fillings are best suited for back teeth (molars), where aesthetics are less of a concern, and where durability is especially important.
5. Glass Ionomer Fillings
What Are They? Glass ionomer fillings are made from a mixture of glass and acrylic materials. They are commonly used for fillings in cavities below the gum line or for baby teeth.
Pros:
• Release Fluoride: One of the unique benefits of glass ionomer fillings is that they release fluoride, which helps to protect the tooth from further decay.
• Good for Temporary Use: Glass ionomer is often used as a temporary filling material or for cavities in areas that aren’t subject to heavy chewing pressure.
• Less Tooth Removal: These fillings require less removal of healthy tooth structure compared to other materials.
Cons:
• Shorter Lifespan: Glass ionomer fillings are not as durable as other materials and may need to be replaced more frequently.
• Aesthetic Concerns: Although they are available in tooth-colored shades, glass ionomer fillings are not as aesthetically pleasing or durable as composite or porcelain.
Best For: Glass ionomer fillings are ideal for temporary fillings or for use in areas where aesthetics aren’t a concern, like below the gum line or in baby teeth.
Choosing the best filling for your cavity depends on several factors, including:
• Location of the cavity: Visible areas, like the front teeth, typically require tooth-colored options such as composite or ceramic. Back teeth, which experience heavy chewing forces, may benefit from more durable materials like amalgam or gold.
• Durability: If you’re looking for a long-lasting solution, amalgam, gold, and ceramic fillings are good choices.
• Cost: If you’re on a budget, amalgam fillings are the most affordable, while gold and ceramic fillings are more expensive.
• Aesthetic preferences: For a natural look, composite, ceramic, and glass ionomer fillings are ideal, while amalgam and gold are more visible.
• Health considerations: Some people prefer to avoid mercury in amalgam fillings or might be allergic to certain materials, so it’s important to discuss your options with your dentist.
Teeth fillings are an essential part of restorative dental care, helping to preserve your tooth’s structure and function.
