UK dentists work in one of three modes: pure NHS, pure private, or "mixed" (the most common). For a routine patient, the practical difference comes down to four things: cost, speed, treatment options, and continuity.
Cost: a real-world comparison
| Routine check-up + clean | NHS: £26.80 Private: £45–£80 |
| Simple filling | NHS: £73.50 (covers any fillings needed) Private: £80–£200 each |
| Root canal (single tooth) | NHS: £73.50 Private: £500–£1,200 |
| Crown | NHS: £319.10 (metal-base or porcelain-fused-to-metal) Private: £500–£900 (all-porcelain, e-max) |
| Tooth extraction | NHS: £73.50 Private: £90–£250 (simple); £200–£450 (surgical) |
| Cosmetic whitening | NHS: not available Private: £250–£600 |
NHS prices are flat-band charges — same nationwide. Private prices vary by clinic and location.
Speed
- NHS: Once you're registered, routine appointments typically 4–8 weeks ahead. Getting newly registered is the hard part — see our finding-a-dentist guide.
- Private: Same-week appointments common. New patients accepted immediately.
Treatment options
- NHS: Anything clinically necessary. The list is broad — fillings, root canals, extractions, crowns, dentures, bridges, gum disease treatment.
- NHS does NOT cover: Cosmetic whitening, veneers, white fillings on back teeth (in some contracts), implants except in specific medical cases, sedation for routine work, multiple cosmetic appointments.
- Private: Anything you're willing to pay for. More choice of materials (e.g. tooth-coloured fillings as default, e-max crowns instead of metal-backed).
The "mixed practice" reality
Most UK dentists are NHS-contracted for a fixed number of UDA units (Units of Dental Activity) per year. Once that quota is filled, they either close their NHS list or shift remaining patients to private. This is why surgeries open and close NHS slots seasonally — the contract resets in April.
A mixed dentist may offer to see you for an NHS check-up but propose private fillings (with the better materials) at extra cost. That's legal as long as they offer the NHS option clearly first. If you're being upsold without the NHS alternative being explained, push back.
Insurance and capitation plans
Private dental insurance (e.g. Bupa, Denplan, Simplyhealth) typically costs £15–£40 per month per adult, and covers routine and minor restorative work with capped contributions. It's mathematically worth it only if you're paying for treatment more than once a year.
If you're mostly healthy with annual check-ups, NHS at £26.80 a year beats insurance hands down. If you're mid-treatment plan or expect ongoing work, capitation plans can pay off.
Quality differences?
Honestly, less than you'd think. UK dentists train to the same standard regardless of NHS/private. The difference is usually time per appointment — private slots are longer, allowing more attention to detail. NHS slots are shorter, by contractual design.
Material choices differ. NHS will give you a perfectly functional crown; private will give you one that's indistinguishable from your real teeth.
The honest summary
- If you can get an NHS slot and your needs are routine — use the NHS. The bands cap your cost.
- If you want speed, choice of materials, or cosmetic work — private. Just shop around for quotes.
- If you mostly need routine check-ups and occasional fillings — capitation plans are a poor deal; pay-as-you-go is better.
