Amalgam Filling or Composite Filling? How to Make the Right Choice?

Amalgam and composite are among the most commonly used filling materials in the treatment of dental caries. Although tooth-colored fillings have become more popular as aesthetic expectations have increased, amalgam fillings are still preferred in certain situations. So what are the differences between amalgam and composite fillings, and which should be chosen in which circumstance?

Amalgam Dolgu Nedir?

Amalgam filling is a metal-based restorative material composed of a mixture of silver, copper, tin, and mercury. It has been used in dentistry for approximately 150 years.

Properties of Amalgam Fillings

  • Silver-grey in color
  • Highly durable
  • Resistant to occlusal forces
  • Average service life of 10–15 years or longer
  • Genellikle daha ekonomiktir

Advantages of Amalgam Fillings

  • Provides high durability on posterior teeth
  • Demonstrates strong performance in large carious lesions
  • Can be applied in situations where moisture control is challenging

Disadvantages of Amalgam Fillings

  • Not aesthetically pleasing
  • Metal rengi belirgindir
  • More tooth structure may need to be removed
  • May expand and contract in response to temperature changes

Kompozit (Beyaz) Dolgu Nedir?

Composite filling is a resin-based aesthetic restorative material that matches the color of natural teeth. It can be used on both anterior and posterior teeth.

Properties of Composite Fillings

  • Matches the natural color of the tooth
  • Bonds chemically to the tooth
  • Requires more minimal tooth preparation
  • Can be completed in a single appointment
  • Average lifespan is between 7–12 years

Advantages of Composite Fillings

  • Significantly superior in aesthetic outcome
  • Provides a natural appearance on anterior teeth
  • Preserves more sound tooth structure
  • Contains no metal

Disadvantages of Composite Fillings

  • May wear down over time under heavy occlusal forces
  • Higher cost compared to amalgam
  • Adequate isolation is required during application

Differences Between Amalgam and Composite Fillings

Estetik Fark

Kompozit dolgular diş renginde olduğu için doğal görünür.
Amalgam dolgular ise metalik renkte olduğu için özellikle görünür bölgelerde estetik açıdan dezavantajlıdır.

Difference in Durability

Amalgam dolgular özellikle arka azı dişlerinde uzun ömürlü performans gösterebilir.
Modern kompozit dolgular da oldukça dayanıklı hale gelmiş olsa da çok büyük restorasyonlarda amalgam hâlâ avantaj sağlayabilir.

Preservation of Tooth Structure

Kompozit dolgu dişe yapışabildiği için daha az sağlam diş dokusu kaldırılır.
Amalgam dolguda mekanik tutuculuk gerektiğinden daha fazla kesim yapılabilir.

Thermal Conductivity

Amalgam metal yapısı nedeniyle sıcak ve soğuğa karşı daha fazla genleşme gösterebilir.
Kompozit dolgular bu açıdan daha stabil davranır.

Health Considerations and Mercury Content

Amalgam fillings contain mercury. Current scientific evidence does not indicate that intact amalgam fillings cause serious systemic toxicity in the general population. However, alternative materials may be preferred in certain specific circumstances.

Which Filling Is Preferred in Which Situation?

Kompozit Dolgu Daha Uygundur

  • For anterior tooth caries
  • When aesthetic expectations are high
  • For small to medium-sized carious lesions
  • In cases where preservation of tooth structure is important

Amalgam Dolgu Tercih Edilebilir

  • For large posterior tooth restorations
  • In individuals with heavy occlusal forces
  • In situations where moisture control is difficult
  • When a more cost-effective treatment is preferred

Should Old Amalgam Fillings Be Replaced?

Not every amalgam filling needs to be replaced. If the filling is:

  • If it is intact
  • If it is not leaking
  • If there is no caries beneath it
  • If it is not causing fractures

takip edilebilir.

However, replacement may be considered in the following situations:

  • If the filling is fractured
  • If new caries has developed beneath it
  • If there is aesthetic concern
  • If the clinician considers it necessary

Frequently Asked Questions

Can tooth-colored fillings be used on posterior teeth?

Yes. Composite materials developed today can be used safely on posterior teeth as well.

Are amalgam fillings harmful?

Scientific studies indicate that intact amalgam fillings do not pose a serious health risk for most individuals. However, alternative materials may be preferred during pregnancy or in certain specific health conditions.

How long does the filling procedure take?

Most filling treatments are completed in a single appointment. The duration may vary depending on the extent of the caries.

Can composite fillings discolor over time?

Factors such as consumption of tea, coffee, and tobacco may cause staining of composite fillings over time.

Conclusion

Amalgam and composite fillings each have distinct advantages. The appropriate choice of filling material should be determined according to multiple factors, including the tooth's location, the size of the caries, occlusal forces, aesthetic expectations, and oral hygiene. Although composite fillings are currently preferred more frequently due to aesthetic and minimally invasive considerations, amalgam fillings may still be an effective option in certain situations.
