Read MoreDental Fillings: Types, Procedures, and Care
Key Takeaways
Amalgam fillings contain 50% mercury mixed with silver, tin, and copper, lasting 10-15 years but creating a dark appearance that makes them unsuitable for visible teeth.
Composite resin fillings bond chemically to tooth structure and can be color-matched perfectly, but typically need replacement every 5-7 years due to wear and staining.
The filling procedure requires removing 1-2mm of healthy tooth structure around the decay to ensure proper adhesion, which permanently weakens the tooth.
Gold fillings are the most durable option lasting 20+ years and cause the least tooth sensitivity, but cost 6-10 times more than amalgam at $800-1,500 per filling.
Untreated cavities can progress through enamel into dentin within 6-12 months, eventually requiring root canal treatment if bacteria reach the tooth's nerve.
Dental fillings are a common treatment for cavities, cracked teeth, or worn-down teeth. When you have a cavity, your dentist will remove the decayed portion of the tooth and then fill the area with a suitable material. This article will guide you through the types of fillings, the procedure involved, and how to care for your filled teeth.
Types of Dental Filling Materials
There are several types of dental filling materials available, each with its own advantages and disadvantages:
Amalgam (silver) fillings: Durable and affordable, but less aesthetically pleasing and may require more tooth structure removal.
Composite (tooth-colored) fillings: Blend in with natural teeth, bond well to tooth structure, and require less tooth removal, but may not last as long as amalgam fillings and are more expensive.
Gold fillings: Durable and strong, but expensive and require multiple office visits.
Ceramic fillings: Resistant to staining and can last more than 15 years, but are costly.
Glass ionomer fillings: Release fluoride to protect the tooth, but are weaker and more prone to wear and fracture compared to other materials.
The Dental Filling Procedure
The process of filling a tooth involves several steps:
The dentist numbs the area around the tooth with a local anesthetic.
The decayed area is removed using a drill, air abrasion instrument, or laser.
The dentist cleans the cavity of bacteria and debris and prepares the space for the filling.
If the decay is near the root, a liner may be applied to protect the nerve.
The filling material is applied in layers and hardened with a special light (for composite fillings).
The dentist shapes, trims, and polishes the filling to achieve the desired result.
Caring for Your Dental Fillings
To maintain your dental fillings and overall oral health, follow these tips:
Brush your teeth twice a day with a fluoride toothpaste.
Floss daily to remove plaque and food particles between teeth.
Use an antibacterial mouthwash to reduce bacteria in your mouth.
Visit your dentist regularly for check-ups and cleanings.
If you experience any pain, sensitivity, or other issues with your fillings, contact your dentist promptly.
In conclusion, dental fillings are a safe and effective way to treat cavities and restore damaged teeth. By understanding the different types of filling materials and properly caring for your filled teeth, you can maintain a healthy, beautiful smile for years to come.

The Bottom Line
Early cavity treatment with fillings preserves more natural tooth structure and costs significantly less than waiting until root canal therapy becomes necessary. The choice of filling material depends on location, budget, and how long you want the restoration to last.
