Which Filling Is Right for You?
Factors to Consider:
Location of the Filling: Amalgam or gold fillings are often more durable for back teeth that suffer more pressure. Composite or ceramic fillings offer a more natural look for visible teeth.
Budget: Amalgam and composite fillings are more affordable, while gold and ceramic fillings are more expensive.
Durability: If longevity is your priority, gold and amalgam fillings are the most durable, while composite and glass ionomer fillings may need to be replaced first.
Aesthetic Preferences: If appearance is a concern, composite and ceramic fillings are designed to match your natural tooth colour, making them a better choice for front teeth.
Conclusion
The best type of dental filling depends on your specific dental needs, budget, and personal preferences. Composite and ceramic fillings offer aesthetic advantages for visible teeth, while amalgam and gold fillings provide superior durability for molars.
