Metal-Free Dentistry
Metal-free dental options, explained from every angle.
Metal-free implants are our flagship section — but metal-free choices extend across crowns, fillings, and restorations. This section covers all of them.
The short answer: Metal-free dentistry covers any treatment that avoids metal alloys in restorations. Options include composite fillings (no mercury), ceramic or zirconia crowns (no metal core), and zirconia implant posts (no titanium). Metal-free options are not inherently superior — they involve genuine trade-offs in durability, cost, and clinical evidence compared to established metal-containing alternatives.

Common questions
What does metal-free dentistry mean?
Metal-free dentistry refers to dental treatments that use no metal alloys in restorations. This includes composite fillings (no mercury or metal), ceramic or zirconia crowns (no metal substructure), and zirconia implant posts (no titanium). The term covers both the materials used and sometimes the philosophy of the practice.
Is metal-free always better?
Not necessarily. Metal-free options are appropriate for patients with specific metal sensitivities, those who prefer to avoid metals for personal reasons, or cases where appearance is a priority. Titanium implants and gold crowns have excellent biocompatibility and longevity records. The right choice depends on your individual situation, values, and dental needs.
What questions should I ask about metal-free options?
Ask: What metal-free alternatives exist for my specific treatment? What are the trade-offs in durability and cost? Do you have experience placing the metal-free option? What does the research show about long-term outcomes? Can I see cases you've done with this approach?
How do I find a metal-free dental provider?
Use our provider directory, filtered for metal-free and zirconia options. You can also look for IAOMT-affiliated practices (International Academy of Oral Medicine and Toxicology), biological dentistry practices, and holistic dental providers.
