NHS vs Private Practice: Material and Workflow Differences

Practices that see both NHS and private patients often ask us why a lab prescription looks different depending on which list the patient is on. The honest answer is that NHS dentistry in England operates under a materials framework that private dentistry doesn’t, and that framework shapes what a lab can offer, what it costs, and how the workflow runs. This is UK-specific: it does not translate to any other health system, and it’s worth understanding if you split your book between NHS and private work.

How NHS restorative work is structured

NHS dental treatment in England is charged in three bands. Crowns, bridges, dentures, inlays and other laboratory-made restorations fall under Band 3, the highest charge band, which stood at £332.10 as of April 2026. That single charge covers the clinical work and the lab-made restoration together, regardless of how many units or how complex the case is within that treatment course.

What sits behind that flat charge is a defined list of permitted materials set out in the NHS dental regulations. In broad terms, NHS crowns can be cast in alloys containing stainless steel, cobalt chromium or nickel chromium, or in alloys with at least a third fine gold, platinum or palladium combined with thermally bonded porcelain. Bridges follow the same alloy rules, with or without a bonded porcelain facing. Dentures are approved in synthetic resin, metal, or a combination of both. Crucially, the choice of material within that list sits with the treating dentist based on clinical need, not with the patient’s preference. A back tooth crown, for example, will often be specified in a metal or metal-ceramic combination rather than full ceramic, because that is the clinically appropriate and NHS-permitted option for that position.

There is also a guarantee built into NHS treatment: if an NHS filling, root filling, inlay, onlay, porcelain veneer or crown fails within 12 months, the same practice repairs or replaces it at no charge. Dentures and bridges sit outside that specific 12-month rule, though repairs to them remain free under NHS terms.

How private material choice differs

Private prescriptions aren’t bound by that approved list. A dentist and patient can choose the material on clinical suitability, aesthetics, and budget rather than a fixed formulary: monolithic zirconia, lithium disilicate (e.g. e.max), layered ceramics, or high-noble metal alloys are all viable options a lab can quote and fabricate for a private case in a way that isn’t available on an NHS prescription. That range also opens up workflow choices: full-contour zirconia milled from a digital scan, for instance, is a private-practice-friendly option that suits a fast, largely metal-free workflow, whereas an NHS metal-ceramic crown still typically involves a cast substructure and hand-layered porcelain.

This isn’t a quality statement, an NHS metal-ceramic crown fabricated correctly is a durable, clinically sound restoration. It’s a materials-availability statement: private work has a wider palette to choose from, and that palette changes what the lab prescription can specify.

What this means for the lab workflow

From our side as a lab, the practical differences show up in a few places:

• Prescription detail. An NHS case prescription needs to land within the approved material list for the tooth position, so we flag anything ambiguous before starting rather than after. A private prescription has more room for the dentist’s material preference, so we confirm that preference against occlusal and aesthetic requirements instead.
• Digital workflow fit. Materials like monolithic zirconia and lithium disilicate are well suited to a digital scan-to-mill workflow, which is where our scanner integration (iTero, 3Shape TRIOS, Medit, Dexis) tends to add the most speed for private cases. NHS metal-ceramic work can still be digitally designed, but the alloy casting and hand-layering steps keep more of the process on the bench.
• Turnaround. Material choice doesn’t change our standard turnaround (10 working days for restorative work, see our turnaround times page), but a complex private case with multiple shade layers or a bespoke aesthetic brief may need more communication back and forth before fabrication starts.

What Flora can fabricate either way

We work with practices across both NHS and private books, and we fabricate within the NHS-approved material list when a case calls for it, or across the wider private material range when it doesn’t. The specification comes from you and your patient’s treatment plan; our job is to build it correctly and get it seating first time, whichever list it falls under. If you’re weighing up which lab fits your mix of NHS and private work, our guide on how to choose a UK dental lab covers what to look for beyond price.
