What a Private Dental Filling Really Costs in the UK (2026)
Last updated 29 September 2026
Fillings are quoted per tooth, not as a flat fee, and the material makes a real difference: white composite fillings generally cost more than amalgam, even for what's otherwise the same size of cavity.
Quick answer: based on 150 practices that publish a price on Keystone, a dental filling costs from £40 to £780, with most practices charging £106 to £195. White composite fillings tend to sit higher in that range than amalgam.
What actually drives the price difference
- Material. White composite fillings cost more than silver amalgam, mainly because they take longer to place and are shaped and polished to match your tooth.
- Size of the cavity. A small filling on one surface of a tooth costs less than a larger one covering multiple surfaces.
- Which tooth. Some practices charge more for fillings on back teeth, which are harder to work on, than for front teeth.
- Number of fillings in one visit. Practices sometimes offer a lower per-filling price when several are done in the same appointment.

Most NHS dentistry in England has moved away from silver amalgam for cosmetic reasons, so if you specifically want it rather than a white filling, ask whether a practice still offers it, since not all do.

How much does a dental filling cost in the UK?
Based on 150 practices that publish a price on Keystone, a filling costs from £40 to £780, with most practices charging £106 to £195. White composite fillings generally cost more than amalgam.
Why do white fillings cost more than silver amalgam ones?
White composite is built up and shaped in layers to match the colour and contour of your tooth, which takes more chair time than packing in amalgam. The material itself is also more expensive.
Do I need a filling replaced if it's old but not causing pain?
Not necessarily. Your dentist will check whether an old filling is still sound at your check-up, and only recommend replacing it if it's cracked, leaking, or decay has developed underneath.
Can a filling be done in one visit?
Yes, a routine filling is normally completed in a single appointment. Larger or more complex cases occasionally need more than one visit, which your dentist would explain beforehand.
