Fillings are a common restorative solution used to repair teeth affected by decay, fractures, or minor structural damage. Modern dentistry offers a variety of filling materials, each designed to restore function, protect the tooth, and maintain a natural appearance. The choice of material can depend on factors such as the tooth’s location, the extent of damage, durability requirements, and aesthetic considerations.
1. Amalgam Fillings
Amalgam has been used in dentistry for over 150 years. This material combines mercury with silver, tin, and copper. It creates a durable compound that withstands chewing forces. Dentists often recommend amalgam for back teeth where strength is key. These fillings typically last 10 to 15 years with proper care. The silver color makes amalgam noticeable when you smile or laugh. Its strength and affordability make it a practical choice for molars.
Some patients worry about the mercury in amalgam fillings. The American Dental Association and the FDA confirm amalgam is safe. It is safe for most adults and children over age six, but pregnant women should discuss alternatives with their dentist. People with mercury allergies should also seek other options. Your dentist can help you weigh these factors.
2. Composite Resin Fillings
Composite resin is a popular choice for fillings. This tooth-colored material blends with your natural enamel. It makes the filling nearly invisible. Dentists can shape the resin to match your tooth’s contours. This helps maintain a natural appearance. The bonding process also preserves more of your natural tooth. Your dentist removes less tooth structure compared to amalgam. The material hardens quickly under a special blue light, and you can resume eating and drinking soon after your appointment.
Composite fillings typically last 5 to 7 years. They cost more than amalgam fillings. The procedure requires more time and skill to place. The material can also stain from coffee, tea, or red wine. Despite these drawbacks, many patients prefer this option. They chose it for its natural look and conservative approach.
3. Ceramic and Porcelain Fillings
Ceramic and porcelain fillings are the most natural-looking option among restorative dental fillings. They resist staining better than composite resin and can last over 15 years with proper oral care. These fillings are often made in a dental lab, though some dentists use CAD/CAM technology to create them in a single visit. Their durability makes them ideal for larger cavities and teeth that handle heavy chewing forces.
Ceramic fillings bond well to teeth and don’t expand or contract with temperature changes like amalgam. Porcelain also closely matches the translucency of natural teeth, making it a great choice for visible teeth. While ceramic fillings are more expensive than other options, many people find their benefits worth the investment. Your dentist will evaluate your specific needs and determine if ceramic fillings are the right choice for you.
4. Glass Ionomer and Specialty Materials
Glass ionomer fillings can be a good choice for certain situations. They release fluoride, which helps prevent more decay around the filling. This makes them useful for cavities near the gum line or for kids’ temporary fillings. They bond well to the tooth and can be placed in moist areas.
Specialty materials like gold fillings offer excellent durability, often lasting 20 years or more. Gold is rarely used today because of its high cost and noticeable appearance, but it remains an option if you prioritize longevity over appearance. Your dentist will explain if any specialty materials are right for you and help you find the best solution for your filling needs.
