Mercury-Free Fillings in Lima | Composite & Ceramic Restorations – Smiles Peru
Smiles Peru is a 100% mercury-free practice. We restore teeth with modern tooth-colored materials — composite resins and porcelain inlays/onlays — instead of traditional amalgam (“silver”) fillings that contain mercury.
These restorations look natural, bond chemically to the tooth, and help reduce the risk of future bacterial leakage that can occur with older amalgam fillings.
Why choose mercury-free restorations?
Traditional amalgam fillings contain approximately 50% mercury and rely on a mechanical interlock with the tooth. Over time, microleakage can develop at the margins.
Modern composite resins and porcelain restorations:
- Create a chemical bond with the tooth structure
- Provide a more natural, tooth-colored appearance
- Help seal the tooth against bacterial infiltration
- Allow more conservative preparation in many cases
- Can be combined with digital CEREC technology for precise inlays and onlays
Types of mercury-free restorations we offer
Composite resin (tooth-colored) fillings
Ideal for small to medium cavities. Placed directly in a single visit. They match the natural tooth color and bond adhesively to the remaining structure.
Porcelain inlays and onlays
Used when more tooth structure is missing or when greater strength is needed.
- An inlay fits within the cusps of the tooth.
- An onlay covers one or more cusps (sometimes called a “partial crown”).
These are fabricated from high-quality ceramic (often with CEREC digital technology) and cemented for a precise, durable, and aesthetic result.
Safe replacement of amalgam fillings
When replacing old amalgam fillings we follow careful isolation protocols:
- High-volume suction to capture particles and vapor
- Rubber dam isolation to protect the patient from ingestion or inhalation
This approach minimizes mercury exposure during the removal process. The tooth is then restored with composite or a porcelain inlay/onlay according to the amount of remaining structure.
Benefits of modern tooth-colored restorations
- Natural appearance that blends with your smile
- Chemical bond that helps protect against microleakage
- More conservative tooth preparation in many cases
- Strong, durable materials (especially porcelain)
- Compatible with digital design and same-day CEREC options
- Completely free of mercury

Frequently Asked Questions
What are mercury-free fillings?
Tooth-colored restorations made from composite resin or porcelain. They contain no mercury and bond chemically to the tooth.
Why replace amalgam fillings?
Many patients prefer to eliminate mercury-containing restorations and benefit from the better seal and aesthetics of modern materials.
Composite filling or porcelain inlay/onlay — which do I need?
Smaller cavities are usually restored with composite. Larger areas of missing structure often benefit from the greater strength of a porcelain inlay or onlay.
Is removing amalgam safe?
Yes. We use high-volume suction and rubber dam isolation to minimize exposure during removal.
How much do these restorations cost?
Pricing depends on the size and type of restoration. Send us photos or X-rays for a personalized estimate.
