BPA-Free Fillings

Every white filling we place is made with composites whose resin is formulated without Bis-GMA, the bisphenol-A-derived monomer found in most conventional filling materials. The same applies to the adhesive underneath.

A precautionary choice of materials, not a treatment. Here is what we use, why, and what it does and does not mean.

What BPA has to do with fillings

Bisphenol A itself is not an ingredient of any dental filling. Most conventional composites are, however, built on Bis-GMA, a monomer synthesised from BPA, and trace amounts of BPA can remain in the material from that synthesis. Studies that measured BPA after conventional fillings or fissure sealants were placed found it mainly in the first hours, with levels returning to baseline within about a day.

Regulators and professional bodies have assessed the BPA contribution from dental materials as very low. We do not dispute that. We simply prefer, where a well-documented alternative exists, to use materials formulated without BPA-derived monomers in the first place, a precaution we consider reasonable for everyone and particularly for children and pregnant patients.

  • BPA is not an ingredient of fillings; the question is the monomer the resin is built on.

  • Conventional composites: mostly Bis-GMA, a BPA-derived monomer.

  • Our composites: resins formulated without Bis-GMA, according to their manufacturers.

Three materials, one rule

We work with three composite systems, each chosen for a purpose. All three are CE-marked medical devices, and each manufacturer documents the absence of Bis-GMA in its resin.

Enamel plus HRi Bio Function (Micerium, Italy)

Used for

Front teeth, layered aesthetic restorations, veneers and larger anterior repairs.

What it is

A light-curing composite whose resin is formulated with UDMA and TCDDMA. The manufacturer states that it "does not contain co-monomers nor Bis-GMA", and its catalogue that it "does not contain bisphenol A".

Why we chose it

Enamel and dentine shades that let us layer a front tooth naturally; the manufacturer reports wear behaviour close to natural enamel in laboratory testing.

Elsodent BIO+ composites (Elsodent, France)

PureShade BIO+ · PureFill2 BIO+ · PureFill Flow BIO+

Used for

Routine fillings in front and back teeth; the flowable version for lining and small defects.

What it is

Urethane-dimethacrylate composites that the manufacturer describes as "BPA-free, no BisGMA, BisEMA, TEGDMA, nor addition of HEMA".

Why we chose it

A complete family, including the adhesive, made in France under the same BIO+ formulation rule.

Admira Fusion (VOCO, Germany)

Used for

Back teeth, children's teeth and larger posterior fillings.

What it is

An ORMOCER, an organically modified ceramic, whose resin backbone is silicon-oxide based. According to the manufacturer it "contains no classic monomers, such as Bis-GMA [BPA], TEGDMA or HEMA". It still contains methacrylate, so it is a composite, not a fired ceramic.

Why we chose it

High filler content and, per the manufacturer's data, low polymerisation shrinkage, which matters in deep posterior cavities.

The bonding agent under every filling is Elsodent HEALBOND MAX BIO+, which the manufacturer describes as a "Formulation without BPA, BisGMA, BisEMA, TEGDMA and with no addition of HEMA". A filling is only as clean as the layer that holds it.

The procedure matters as much as the material

  1. Diagnosis first.

    Decay is assessed on examination and imaging; a filling is proposed only where the tooth needs it.

  2. Isolation.

    Rubber dam isolation and high-volume suction during placement, polishing and removal.

  3. Minimal preparation.

    Only the diseased tissue is removed; the healthy tooth structure is kept.

  4. Layering and curing.

    The composite is placed in thin layers and light-cured in stages, following the manufacturer's protocol for each material.

  5. Finishing.

    Contact points, bite and polish are checked so the filling wears with the tooth, not against it.

Replacing old fillings

We replace an existing filling when it is failing, leaking or decayed underneath, not to make a point. Amalgam fillings are removed under our SMART protocol.

What a filling costs, and how long it lasts

Filling prices are listed openly on our price list, by size and number of surfaces.

How long a composite lasts depends more on the size of the filling, the bite and home care than on the brand; we check every filling at your recall visits.

Frequently asked questions

Are BPA-free fillings safer than ordinary ones?

The BPA contribution from conventional fillings has been assessed as very low by regulators. BPA-free composites are a precautionary choice: they avoid a BPA-derived monomer at the source. We make no health claims beyond the materials' documented composition.

Do your fillings contain any BPA at all?

BPA is not an ingredient of any of them, and the resins are formulated without Bis-GMA. Trace contamination has been measured in composites of all kinds, which is why we say "formulated without", not "zero".

Are these materials as durable as conventional composites?

Their manufacturers report mechanical properties in the range of modern composites, and clinical studies of Admira Fusion of up to two years report acceptable performance. Longevity depends mostly on the size of the filling, your bite and your home care.

Do you test whether I tolerate the material?

Most patients do not need testing. For patients with multiple sensitivities or a serious medical condition we can arrange blood-based compatibility testing before treatment.

Material compatibility testing →

Can you replace my old fillings with BPA-free ones?

Yes, when a filling is failing or decayed underneath. We do not recommend removing sound fillings only to change the material. Amalgam is removed under the SMART protocol.
