Quick answer · Updated July 2026
For routine dental costs, a cash plan beats PMI dental add-ons on pure arithmetic: Westfield's Level 1 at £8.58/month includes £45/year dental cashback (plus optical and therapies), Medicash starts at £7.20 with dental across check-ups, hygienist and restorative work, and BHSF from £9.63. NHS Band 2 treatment costs £73.50 — two check-ups and one filling a year can already justify an entry tier (verified July 2026).
Key Facts · 2026-07-17
- Westfield Good4you Level 1 (£8.58/month, July 2026): dental £45/year, plus optical £45/2yr and therapies £200 — rising to £255 dental at Level 5 (£52.35).
- Medicash personal plan from £7.20/month covers dental check-ups, hygienist visits, crowns, bridges and fillings within tier limits; children free (July 2026).
- Dental accident cover: Westfield includes £100–£500 by level — worth noting for contact-sport families.
- PMI comparison: only Bupa includes dental as standard (£300 allowance); AXA's add-on caps at 80% of £400 (July 2026).
Making the tier maths honest
Count last year's actual dental spend: two adult check-ups, one hygienist visit each, one filling — roughly £150–£250 for an NHS family, more privately. Westfield's Level 2 (£17.57/month) returns up to £85 dental + £90 optical + £425 therapies; Level 1 at £8.58 suits lighter users. The plans pay cashback against receipts up to the limit — NHS or private dentistry both count, which matters as NHS dentist access tightens. Qualifying periods apply to some benefits at most providers; check before your first claim (July 2026).
Where cash plans stop
Annual limits are hard ceilings: implants, orthodontics and cosmetic dentistry blow through every tier and aren't the product's job. Nor is emergency-heavy cover — accident benefits are modest fixed sums. For predictable maintenance dentistry, though, entry tiers routinely return more than they cost — the rare insurance where claiming is the point (verified July 2026).
Who This Isn't For
If you need major restorative work already quoted — implants, orthodontics — a cash plan's £45–£255 annual dental limit is irrelevant to four-figure treatment plans; dental payment plans or self-pay negotiation fit better. And if your PMI already carries dental cashback (AXA's 80% to £400), don't double-pay for the same receipts.

Frequently Asked Questions
Usually, if you attend check-ups: entry tiers (£7.20–£9.63/month, July 2026) return their premium in routine dental and optical cashback for most families — Westfield's Level 1 alone offers £45 dental + £45 optical + £200 therapies against ~£103/year of premiums.
Yes — cashback is paid against receipts from either, up to your tier's annual limit (provider terms, July 2026). That flexibility matters as NHS dental access tightens; you claim the same way wherever you're treated.
