When it comes to repairing cavities, one of the most common questions patients ask is: “Should I choose amalgam or composite fillings?” Both types of dental fillings are widely used to restore decayed teeth, but they differ in materials, aesthetics, durability, and cost.

At Night and Day Emergency Dentist, we treat hundreds of patients every week who walk in with toothaches, chipped teeth, or broken fillings, often needing a fast yet reliable fix. That’s why we believe it’s essential to understand the difference between amalgam vs composite fillings, especially if you’re visiting us in an emergency.

In this guide, we’ll break down the key differences between amalgam vs composite fillings so you can make the right choice for your oral health and lifestyle.

Which Filling Is Right for You?

  1. Tooth Location: Back molars? Amalgam for strength. Front teeth? Composite for aesthetics.
  2. Cavity Size: Small to medium cavities suit composite; large ones may need amalgam.
  3. Budget: Amalgam is often more affordable, but composite offers better appearance.
  4. Personal Preferences: Mercury-free? Go composite. Want invisibility? Choose composite.

What Dentists Recommend

  • Composite is ideal for small to medium visible cavities.
  • Amalgam suits large restorations in high-stress areas.
  • Decision depends on your bite, decay, habits, and cosmetic goals.

Conclusion

Both amalgam and composite fillings offer reliable solutions for treating tooth decay, but they come with different benefits. If you value strength and durability for your molars, amalgam fillings may be right for you. If you prefer a more natural look and minimal invasiveness, composite fillings are likely the better option.

The best way to decide? Talk to your dentist. They can assess your individual case and recommend the most suitable material for long-lasting dental health.

FAQs – Amalgam vs Composite Fillings

I chipped my tooth at night—can I get a filling immediately?+
Yes. At Night and Day Emergency Dentist, we offer both amalgam and composite fillings even during late-night or weekend emergencies. We’ll recommend the best option based on the tooth and urgency.
Which filling is safer—amalgam or composite?+
Both are considered safe by dental professionals. If you’re concerned about mercury in amalgam, we can opt for composite, which is mercury-free and more aesthetically pleasing.
Will my dental filling match my tooth color?+
If you choose a composite filling, yes—it will match your natural tooth shade. These are ideal for front teeth or anywhere that looks matter most.
How long will a filling take during an emergency visit?+
Most fillings take 30–60 minutes, depending on the material and location. Amalgam tends to be a quicker fix, while composite may need more time to layer and cure.
Are composite fillings strong enough for back teeth?+
Yes, but if you’re a heavy grinder or the damage is deep, we might recommend amalgam for its superior strength. We’ll assess the situation in-clinic.
Can I eat right after the filling?+
You should wait until the numbness wears off. Amalgam hardens quickly but reaches full strength over 24 hours. Composite hardens instantly with our light-curing tools.
