White fillings vs amalgam — what’s the difference?

Amalgam fillings — the silver-coloured fillings that have been used in dentistry for decades — are still considered clinically effective, but they are increasingly unpopular for several reasons. They are visually obvious, particularly in teeth that are visible when you smile or speak. They also require more removal of healthy tooth structure to create the mechanical retention needed, and over time they can cause the surrounding tooth to discolour.

White composite fillings bond directly to the tooth surface. This means less drilling, better preservation of healthy tooth structure, and a result that is virtually invisible. They are suitable for both back and front teeth and can be closely matched to the shade of your surrounding enamel.

At Staveley Dental Care, white composite is our standard filling material for new cavities. For patients with existing amalgam fillings who would like them replaced, we offer a straightforward replacement service.

Replacing old amalgam fillings

Many patients come to us specifically to have old amalgam fillings replaced with white composite. Common reasons include concerns about appearance, particularly in visible teeth, or older fillings that are showing signs of wear, cracking, or leakage around the margins.

Replacing amalgam fillings is a straightforward procedure carried out under local anaesthetic. The old filling is carefully removed, the cavity is cleaned and prepared, and a new tooth-coloured composite filling is placed and shaped to restore the natural contour of the tooth.

Not every amalgam filling needs to be replaced. If your existing fillings are intact and well-sealed, there may be no clinical reason to replace them. We will always give you an honest assessment during your examination and only recommend replacement where there is a genuine benefit, whether clinical or cosmetic.

What to expect at your appointment

Step 1 — Examination and assessment

We examine the tooth or teeth involved, assess the existing filling or cavity, and confirm the most suitable approach. For replacement of amalgam fillings, we discuss which teeth would benefit most and give you a clear cost estimate before proceeding.

Step 2 — Local anaesthetic

The area is numbed thoroughly before treatment begins. We take time to ensure you are completely comfortable before proceeding.

Step 3 — Filling placement

The old filling or decay is removed carefully. The cavity is cleaned, conditioned, and the composite material is applied in layers, each hardened with a curing light. The filling is then shaped and polished to match the natural contour and shade of your tooth.

Step 4 — Check and polish

We check your bite carefully to ensure the filling sits comfortably and make any fine adjustments needed. The finished result is smooth, natural-looking, and virtually indistinguishable from your surrounding tooth.

Are white fillings as durable as amalgam?

Modern composite materials have improved significantly in recent years and are now highly durable, particularly for fillings in back teeth where biting forces are greatest. With good oral hygiene and regular check-ups, white fillings can last many years.

The longevity of any filling depends on the size of the cavity, the location of the tooth, and how well the tooth is looked after. Larger cavities in heavily loaded back teeth may sometimes be better restored with an inlay or crown rather than a direct composite filling — we will always discuss the most appropriate option for your situation.

How much do white fillings cost in Chesterfield?

The cost of a white filling depends on the size of the cavity and the number of surfaces involved. Replacement of amalgam fillings is priced per tooth. We provide a clear cost estimate before treatment begins so there are no surprises.

White fillings are available as both NHS and private treatments at Staveley Dental Care, depending on the clinical need and the tooth involved. Speak to our team for details about what is covered under NHS treatment and what is available privately.

Common questions about white fillings in Chesterfield

Do white fillings hurt?

The procedure is carried out under local anaesthetic so you should not feel pain during treatment. Some mild sensitivity in the tooth for a day or two afterwards is normal and usually settles quickly.

How long do white fillings last?

With good oral hygiene and regular dental check-ups, white composite fillings typically last five to ten years or more. Larger fillings in heavily used back teeth may have a shorter lifespan than smaller fillings in less demanding locations.

Can all amalgam fillings be replaced with white composite?

In most cases yes, but very large old amalgam fillings may be better replaced with an inlay, onlay or crown rather than a direct composite filling. We assess each tooth individually and recommend the most appropriate restoration.

Are white fillings available on the NHS?

White fillings on back teeth may be available on the NHS in some circumstances. We will advise you on what is covered under your NHS treatment and what is available as a private option during your appointment.

Will my filling be noticeable?

White composite is colour-matched to your surrounding teeth and polished to a natural finish. In most cases the filling is virtually invisible to anyone looking at your smile.

Is it safe to have amalgam fillings removed?

Amalgam removal is a routine procedure. We follow recommended protocols for safe removal and take precautions to minimise any exposure during the process. If you have concerns about amalgam removal, please speak to our team before your appointment.
