Cost-effective: They are one of the most affordable filling materials.
Strong: These fillings are particularly suited for large cavities in back teeth where strength is essential.
Disadvantages:
Aesthetics: Amalgam fillings are not tooth-colored and can be visible, which may not appeal to those who want a more natural look.
Mercury content: Amalgam contains mercury, which some people prefer to avoid, although studies have shown it is safe in small amounts.
3. Ceramic Fillings
Ceramic fillings are made from porcelain or other ceramic materials. They are highly durable and can be used for both small and large cavities.
Advantages:
Aesthetic appeal: Ceramic fillings are tooth-colored, making them an excellent choice for visible areas.
Durability: Ceramic is resistant to wear and tear and can last a long time.
Biocompatible: These fillings are made from materials that are biocompatible and unlikely to cause allergic reactions.
Disadvantages:
Cost: Ceramic fillings tend to be more expensive than other options due to their complex manufacturing process.
Brittleness: Ceramic is harder and more brittle than composite materials, which may make them prone to chipping under heavy pressure.
4. Glass Ionomer Fillings
Glass ionomer fillings are made from a mixture of glass and acrylic. They are commonly used for fillings in areas that are less visible, such as the back teeth.
Advantages:
Fluoride release: Glass ionomer fillings release fluoride, which can help prevent further tooth decay.
Biocompatible: They are highly compatible with the natural structure of the tooth.
Minimal tooth preparation: Like composite resin, glass ionomer fillings require minimal removal of healthy tooth structure.
Disadvantages:
Aesthetic concerns: Glass ionomer fillings are not as tooth-colored as composite resin or ceramic fillings, so they may not be ideal for visible areas.
Durability: They are less durable than other materials, and they may wear down more quickly.
5. Resin Ionomer Fillings
Resin ionomer fillings are similar to glass ionomer fillings but have the added benefit of resins to improve strength. They are often used in areas with less chewing pressure.
Advantages:
Fluoride release: These fillings also release fluoride, which can help protect the tooth from decay.
Good for children: Resin ionomer fillings are often used in pediatric dentistry for fillings in baby teeth.
Disadvantages:
Limited durability: Resin ionomer fillings may not last as long as other materials, especially under the pressure of chewing.
Aesthetic limitations: They are not as aesthetically pleasing as composite resin or ceramic options.
6. Resin-Based Composites
Resin-based composites are a hybrid material that blends the strengths of composite resins and glass ionomers. They offer a balance of strength and aesthetics.
Advantages:
Tooth-colored: These fillings blend well with the natural tooth, making them suitable for visible areas.
Durable: Resin-based composites are strong and resistant to wear.
Disadvantages:
Expensive: They are more expensive than some other materials, such as amalgam or glass ionomer.
Shrinkage: These fillings may shrink slightly as they harden, which could lead to gaps over time.
7. Zinc Oxide-Eugenol Fillings
Zinc oxide-eugenol fillings are a temporary filling material that is often used to protect a cavity while a permanent filling is being prepared.
Advantages:
Easy to apply: These fillings are easy to place and do not require complex procedures.
Painless: The material is gentle on the tooth and typically does not cause irritation.
Disadvantages:
Temporary: Zinc oxide-eugenol fillings are not intended for long-term use and are generally replaced after a short period.
Limited durability: These fillings do not hold up well under chewing pressure and may need to be replaced more frequently.
8. Resin-Modified Glass Ionomer Fillings
Resin-modified glass ionomer fillings are an improvement over traditional glass ionomer fillings, offering added strength and durability.
Advantages:
Fluoride release: Like glass ionomer fillings, resin-modified versions also release fluoride.
Good for children’s teeth: These fillings are often used in pediatric dentistry due to their ability to release fluoride and their lower wear rate.
Disadvantages:
Limited durability: While stronger than regular glass ionomer, resin-modified glass ionomer fillings are still not as durable as composite resin or ceramic fillings.
Aesthetic concerns: They are not as aesthetically pleasing as other options, especially in visible areas.
9. Porcelain Inlays and Onlays
Porcelain inlays and onlays are custom-made dental fillings that are used to restore more substantial damage to teeth. They are often made in a lab and then placed by the dentist.
Advantages:
Strong and durable: Porcelain inlays and onlays are highly durable and resistant to wear.
Aesthetic appeal: These fillings are tooth-colored and blend seamlessly with the natural tooth.
Disadvantages:
Expensive: Porcelain fillings tend to be one of the more expensive options due to the custom fabrication process.
Time-consuming: The procedure requires two visits to the dentist, which can be less convenient for some patients.
10. Silver Diamine Fluoride (SDF) Fillings
Silver diamine fluoride is a liquid that is applied directly to the decayed area of the tooth to stop decay in its tracks. It is commonly used in patients who cannot tolerate traditional fillings.
Advantages:
Non-invasive: SDF is applied directly to the tooth without the need for drilling or anesthesia.
Fast: The process is quick and can often be completed in a single visit.
Disadvantages:
Temporary: Silver diamine fluoride is not a permanent solution and is often used as a stopgap measure until a more durable restoration can be applied.
Aesthetic concerns: It may stain the tooth, making it less suitable for visible areas.
