Amalgam contains mercury, which is a known toxin. The amounts in a filling are small, but we don't think there's a good reason to put mercury in anyone's mouth when we have safe, durable, better-looking alternatives. We haven't used amalgam in years.

Yes, when it's done properly. Drilling out amalgam releases mercury vapour, so we use barrier systems - a rubber dam, high-volume suction, and a separate clean air supply - to protect you during removal. Without those precautions, removal can actually be more dangerous than leaving the amalgam in.

Cerec ceramic if you want the most durable repair (around 20 years, give or take five). Composite for most everyday fillings (around 10 years, give or take five). Glass ionomer for temporary fillings or sensitivity-prone teeth (around 5 years). We'll recommend what fits your situation - durability, position in the mouth, budget and cosmetics all play a part.

Cerec ceramic: ~20 years. Composite: ~10 years. Glass ionomer: ~5 years. Natural tooth structure properly looked after lasts over 100 years, which is why we always recommend prevention over repair where it's possible.

A Cerec ceramic filling is a solid piece of porcelain made in our practice in a single visit. It's more durable, doesn't shrink as it sets, and won't stress the tooth. A composite filling is a plastic-and-ceramic material placed in layers - more common, faster, but doesn't last as long.

For most everyday fillings, yes. For larger repairs where you need maximum durability, Cerec ceramic is actually stronger than amalgam ever was and lasts longer.

No. We numb the tooth properly before we start. You may feel pressure or vibration during the work, but no pain. If you're nervous about injections, tell us before the appointment and we'll go through it with you.
