Dental fillings are one of the most common restorative treatments used to repair teeth damaged by decay or minor fractures. They help restore the tooth's function, shape, and strength while preventing further decay. If you've ever had a cavity, chances are your dentist recommended a filling.
Fillings are essential because untreated cavities can lead to severe pain, infections, and even tooth loss. Modern dentistry offers various filling materials, each with unique benefits. Whether you need a quick fix or a long-term solution, understanding dental fillings can help you make informed decisions about your oral health.
In this guide, we’ll explore the different types of fillings, signs you may need one, the procedure, pain management, aftercare, and costs. Let’s dive in!
1. Amalgam Fillings (Silver Fillings): Durable and cost-effective, these have been used for over a century. They contain a mix of metals, including mercury, silver, and tin. While safe, their metallic appearance makes them less popular for visible teeth.
2. Composite Resin Fillings (Tooth-Colored): Made of a plastic and glass mixture, these blend seamlessly with natural teeth. They’re ideal for front teeth or visible areas but may wear out faster than amalgam.
3. Ceramic Fillings (Porcelain): Highly aesthetic and stain-resistant, these are custom-made in a lab. They’re more expensive but offer a natural look and durability.
4. Gold Fillings: Long-lasting and biocompatible, gold fillings are custom-cast but costly. They’re often chosen for their strength in back teeth.
5. Glass Ionomer Fillings: These release fluoride, helping prevent further decay. Often used for children or temporary fillings.
Your dentist will recommend the best type based on cavity size, location, budget, and aesthetic preferences.
How do you know if you need a filling? Here are key warning signs:
Regular dental check-ups help detect cavities early. If you experience these symptoms, schedule an appointment to prevent further damage.
Step 1: Numbing the Area – Your dentist administers local anesthesia to ensure a pain-free experience.
Step 2: Removing Decay – Using a drill or laser, the dentist removes the decayed portion of the tooth.
Step 3: Cleaning & Preparing – The cavity is cleaned to eliminate bacteria and debris.
Step 4: Filling Placement – The filling material (composite, amalgam, etc.) is applied in layers and hardened.
Step 5: Polishing & Bite Check – The dentist shapes and polishes the filling for a natural feel.
The entire process takes 20–60 minutes, depending on the filling type and cavity size.
Many patients worry about pain during fillings, but modern dentistry ensures minimal discomfort:
Severe or prolonged pain may indicate complications—contact your dentist if discomfort persists.
Proper care extends the life of your filling:
Most patients resume normal activities immediately.
Fillings aren’t permanent but can last years with care:
Factors like oral hygiene, diet, and grinding habits affect longevity. Regular check-ups help detect wear early.
Filling costs vary by material and location:
Most dental insurance plans cover fillings, especially amalgam or composite. Check your policy for details.
