"Private dental insurance" is one label for two quite different products: plans that pay you back part of a dentist's bill, and plans where you pay your dentist a monthly fee that is set at the practice. Neither is the dental extra some private medical policies carry, and neither pays for hospital care. This page sorts out how dental-only plans work, what they tend to cover, where they stop, and how the cost compares with NHS dental charges. If the real question is a dental plan against a medical policy with dental built in, an FCA-authorised broker can explain the medical side by phone, free, once you send your details with the form on this page.
Two kinds of plan sold as dental cover
The first kind works like insurance. Simplyhealth's dental plan page lets you "use your own local NHS or private dentist"; you pay the dentist, send a photo of the receipt, and the plan pays back a percentage up to a yearly limit. It says there are "no excesses to pay".
The second kind is a dental payment plan, and Denplan, which is part of Simplyhealth, is the best-known. Denplan describes its plans as "Designed to spread the cost of treatments" and its model for dentists as "a reliable capitation model", meaning the dentist is paid a regular fee for each member. You choose a Denplan member dentist, attend a first check-up, and then pay a monthly fee. The practice sets that fee: Denplan's page says "your fees are actually set by your dental team", based on your oral health, the treatment you are likely to need and the practice's running costs. Two members on the same Denplan plan can therefore pay different amounts, and the fee can be reviewed.
The practical difference is who you deal with. With a reimbursement plan you can usually keep your dentist, and the insurer sets the limits. With a payment plan you need a dentist who belongs to the scheme, and the dentist sets the price and decides what is clinically necessary.
What dental-only plans tend to cover
Both kinds are built round routine care first. Denplan's patient pages (read 4 November 2026) list four plan types with different contents:
| Denplan plan | Check-ups | Hygiene | X-rays | Fillings, crowns, bridges |
|---|---|---|---|---|
| Care | Yes | Yes | Yes | Yes, within the terms of your contract |
| Essentials | Yes | Varies by dentist | Varies by dentist | No |
| Hygiene | No | Yes | No | No |
| For Children | Yes | Varies by dentist | Varies by dentist | Varies by dentist |
Even the widest, Denplan Care, covers major restorative work such as crowns, bridges, dentures and extractions only as "deemed clinically necessary, as outlined in your contract", and its list adds "(lab fees not included)". Emergency and injury cover is an optional extra: Denplan lists Dental Emergency and Injury Cover at 60p per person per month, with the extra benefits applying when you are more than 40 miles from your registered practice.
Simplyhealth's dental plan page, read on 4 November 2026, shows the reimbursement version. It pays "up to 100%" of check-ups, up to 75% of a scale and polish and up to 50% of treatment including crowns, bridges, fillings and dentures, with a separate accident benefit that needs treatment to be sought within 30 days and a dental emergency visit benefit. The plan starts at "From just £12.30 a month". Its own level-by-level limits are set out on Simplyhealth's dental plan, so they are not repeated here; they matter mainly because a half-payment on treatment means a big bill still leaves you a large share.
The same page footnote says: "Cover applies after you have been with us for 3 months. Pre-existing conditions, treatment identified in a qualifying period or cosmetic dentistry are not covered." Orthodontics, implants and other costly work vary by plan and level, so what a particular plan does with them is worth reading in its table of cover before you join.
Waiting periods, first visits and renewal
Read the start-up rules before the price. Simplyhealth's treatment, accident and emergency benefits start once you have been with the plan for three months and leave out problems that already exist, so the first months are the least useful ones if you join because a tooth already hurts. Denplan works differently: you start with a first check-up, discuss your plan with the dentist and then complete the application, so the practice assesses your mouth before your monthly fee is set.
Two more things to ask before signing: whether the fee or limits can change at review, and whether you commit to a minimum term. Simplyhealth's page describes a "12 month contract".
NHS dental charges to compare against
The comparison most readers need is with what an NHS dentist charges. These rules differ by country, so check the one you live in.
England
The NHS Business Services Authority lists charges "From 1 April 2026": Band 1 £27.90, Band 2 £76.60, Band 3 £332.10, and £27.90 for urgent treatment. The NHS website (read 4 November 2026; it prints "Page last reviewed: 13 March 2025") explains that treatments are grouped into three bands and that "If you need a mix of treatments from different bands, you'll pay for the cost of the highest band of treatment you're having." Band 1 includes an examination, X-rays if clinically needed and, where clinically needed, scaling. Band 2 adds fillings, root canal treatment and extractions. Band 3 adds crowns, dentures and bridges. Treatment within two months in the same or a lower band costs nothing extra.
Scotland, Wales and Northern Ireland
Scotland has no bands. NHS inform (last updated 27 July 2026) says examinations are free for everyone in Scotland and treatment is free for everyone aged under 26; other NHS patients who pay for their treatment pay 80% of its cost, capped at £384 for each course of treatment. Wales has moved to fixed charges for care packages. The Welsh Government's charges page (last updated 27 July 2026) lists £27.21 for a new patient assessment, £36.03 for simple restorative care (fillings and extractions for up to 4 teeth), £68.75 for extensive restorative care, £140.44 for crowns or bridges and £86.40 for dentures, with laboratory charges for dentures paid separately unless you are exempt; urgent care is £37.50 and the most you pay for a course of treatment is £384. Northern Ireland sets its own charges, which are published on the NI Direct website.
An NHS band is one charge for a whole course of treatment. A reimbursement plan pays a share of each private bill, and a payment plan swaps the charge for a monthly fee. Which of these is cheaper over a year turns on your dentist and how much work your teeth need.
Dental-only plan or dental on a medical policy
A dental plan does not pay for a hospital stay, a consultant or most of what a medical policy exists for; those are not what a dental plan is for. The other route is a private medical policy with a dental add-on, which private health insurance and dental cover covers in detail, including limits and waiting periods. The two answer different questions: one smooths the cost of routine dentistry, the other pays for treatment of illness. Some people take both.
If dental is one factor among several, the broker can explain how a medical policy might sit beside a separate dental plan when they ring. Their work is medical insurance, so put questions about a dental-only plan to its provider.
For how insurers handle dental on their medical policies, see Aviva, AXA Health and Vitality. For a cash plan alternative, health cash plan providers compares who pays towards dental.
Questions readers ask about private dental plans
What are private dental plans?
They are monthly plans bought for routine dentistry: either insurance that refunds part of each bill, or a payment plan with a member dentist. Neither pays for hospital treatment. They differ in who sets the price and whether you can keep your own dentist.
Can I keep my NHS dentist?
Simplyhealth's reimbursement plan is not tied to one practice, whether yours is NHS or private. Denplan works through its member dentists, found with its "Find a dentist" search, so you may need to move practice.
Does a plan help if I am away from home?
Simplyhealth's page says "Worldwide accident and emergency cover" is included, for trips of up to 28 days and only after the three-month wait. Denplan says it has no dentists abroad and that temporary emergency treatment abroad is covered through Denplan if you have its Dental Emergency and Injury Cover, with the amount set by your policy limit. Keep every receipt.
Why does the same Denplan plan cost different amounts?
Because the practice sets the fee, from your oral health needs and its own costs, and may review it for business costs, regulation or inflation.
Whichever way you lean, the decision starts with how much dental work you expect and whether you also want medical cover. If medical cover is part of the picture, request a call-back from the enquiry panel and say which dental plan you already hold or are weighing up, so the broker can explain how a medical policy would sit beside it.
