Types of Dental Fillings

Dental fillings are one of the most common treatments used to restore teeth damaged by decay or cavities. They help protect the tooth from further damage and restore its function and appearance. With advancements in dental materials, there are now various types of dental fillings available to suit different needs. In this blog, we’ll explore the most common types of dental fillings and help you understand which one may be right for you.

Amalgam Fillings
Amalgam fillings, also known as silver fillings, have been used for over a century. They are composed of a mixture of metals including silver, mercury, copper, and tin. Despite the controversy over the mercury content, amalgam fillings are durable, cost-effective, and can withstand significant chewing forces.

Advantages:
Durability and strength
Cost-effective
Less sensitivity to moisture during placement
Disadvantages:
Aesthetic concerns due to their metallic color
Possible sensitivity to metals
Requires removal of some healthy tooth structure for placement


Composite Fillings

Composite fillings are made of a resin-based material that is designed to match the color of your teeth, providing a more natural appearance. They are suitable for both front and back teeth and are bonded directly to the tooth structure, which helps to support the remaining tooth.

Advantages:
Aesthetic appeal due to color matching
Bonding to the tooth can provide additional support
Minimal removal of healthy tooth structure
Disadvantages:
Less durable compared to amalgam
Can be more expensive
Susceptible to staining over time


Ceramic Fillings

Ceramic fillings, often made from porcelain, are another tooth-colored option that offers a natural appearance. They are more resistant to staining compared to composite fillings and can be used for both aesthetic and functional purposes.

Advantages:
Excellent aesthetic match to natural teeth
High resistance to staining
Long-lasting with proper care
Disadvantages:
More expensive than composite and amalgam fillings
Requires more than one dental visit if the filling is fabricated in a lab
Brittle compared to metal fillings


Gold Fillings

Gold fillings, also known as gold inlays or onlays, are custom-made in a dental laboratory and then cemented into place. Gold fillings are highly durable and can last for many years if properly maintained.

Advantages:
Exceptional durability and longevity
Biocompatible with gum tissues
Less wear to the opposing teeth compared to amalgam
Disadvantages:
High cost due to the material and fabrication process
Requires multiple dental visits
Noticeable color, which might be a concern for some patients


Glass Ionomer Fillings

Glass ionomer fillings are made from a combination of acrylic and a specific type of glass that releases fluoride, which can help protect the tooth from further decay. These fillings are often used in areas not subject to heavy chewing pressure, such as around the gum line or in primary teeth.

Advantages:
Fluoride release helps prevent further decay
Good for patients with high caries risk
Tooth-colored, though less aesthetic than composite
Disadvantages:
Less durable and more prone to wear and fracture
Limited use in areas subject to heavy chewing forces
Dental Filling Procedure

The dental filling procedure typically involves the following steps:

Examination and Diagnosis: The dentist will examine your teeth and may take X-rays to determine the extent of the decay or damage.

Anesthesia: A local anesthetic is administered to numb the area around the affected tooth to ensure a pain-free procedure.

Removing the Decay: The decayed portion of the tooth is removed using a dental drill, laser, or air abrasion tool. The area is then cleaned to remove bacteria and debris.

Conclusion
The best type of dental filling depends on the location of the cavity, your aesthetic preference, budget, and your dentist’s recommendation. At CornealDent, we help you choose the right dental filling that suits your needs while ensuring long-lasting oral health.
