Why Are White Fillings So Expensive?

White fillings can cost more than traditional silver amalgam dental fillings because they require more skill, time, and precision to place.

At The Modern Dentist, white fillings cost between £200 and £450 per tooth, depending on the size and complexity of the restoration.

Many factors affect the overall cost of white dental fillings, from the materials used to the expertise required.

Together, these factors help explain why white fillings are so expensive compared to silver alternatives.

White Vs Silver Fillings Cost Difference

Silver amalgam fillings have been the standard for decades because they're fast to place and inexpensive to produce.

On the other hand, composite is built from materials that cost more and takes expertise to place well.

Here's a quick cost difference breakdown:

Why Do White Fillings Cost More?

A white filling costs more than a silver one for several reasons:

Material Cost

Amalgam is usually a mix of silver, tin, copper, and mercury, which are all relatively inexpensive.

Higher-grade composite, which is the kind used to blend seamlessly with a natural tooth, has a much higher cost.

Technique Sensitivity

Placing a white filling correctly takes more skill and precision.

The tooth has to stay completely dry throughout bonding, usually with a rubber dam.

The composite resin also needs to be shade-matched, then built up using a layering technique, which helps it maintain its strength.

Time In The Chair

A composite filling done properly can take more time than silver amalgam fillings, often around 50 minutes on average at The Modern Dentist.

That extra time in the chair is to account for the additional steps composite work requires.

Equipment and materials

Rubber dams, polishers, curing lights, bonding agents, and shade guides are all part of placing a composite filling well.

Using the right instruments adds to the overall cost.

Training

Composite techniques and materials develop relatively quickly, and staying current means that your dentist needs ongoing training.

That investment in your dentist's expertise is what separates a filling that looks natural and lasts from one that doesn't.

Aesthetics demand more precision

Part of correctly placing a composite filling is making sure that they match your tooth's natural colour.

A white filling is usually on full display when you smile, so any small flaw in colour or shape is much more noticeable.

Are White Fillings Worth The Extra Cost?

Whether a white filling is a worthwhile investment depends almost entirely on how well it's placed.

A well-maintained composite filling can easily last 7 to 10 years, or sometimes even longer with proper dental hygiene and aftercare.

While a higher price doesn't always guarantee better quality, an unusually low-cost filling may reflect less time or expertise, potentially leading to problems and more expensive repairs later.

What Is The Difference In Cost Between NHS And Private White Fillings?

The NHS doesn't typically cover white fillings on back teeth, although they may be available for front teeth when clinically necessary.

This is why most people end up with a white filling on front teeth and silver ones on molars on the NHS.

As of July 2026, any NHS dental filling treatment currently costs £76.60 (Band 2), regardless of which material is used.

If an NHS practice offers white fillings privately, the fee is usually cheaper than a fully private clinic, averaging around £150-200.

Private practice pricing varies between £200 and £400, and sometimes more depending on how complex the procedure is.

Your dentist should be transparent about the cost before any work goes ahead.

Always confirm what it will cost before agreeing to treatment.

How To Get The Best Value From A White Filling

Here are a few ways to get the most out of your white dental fillings:

• Book regular dental check-ups. Your dentist can catch problems early, and issues within the first year or two are often repaired free of charge under guarantee.

• Keep up with your hygienist visits. Professional cleaning supports the longevity of your filling and your overall oral health.

• Maintain proper care at home. Brushing twice daily with fluoride toothpaste and flossing daily both make a noticeable difference.

• Watch your diet. Cutting back on sugar and acidic foods and drinks helps to protect your filling and the tooth around it.

• Ask about a night guard if you grind or clench your teeth, since the pressure can loosen or chip a filling over time.

• Avoid using your teeth as tools, and steer clear of habits like nail biting that tend to strain a repair.
