How Dental Plans Work in the UK
Updated April 2026 • 5 minute read
The short version
There are three main types of dental cover in the UK. Each works differently, suits different people, and covers different treatments. Understanding which type you are buying is essential before signing up.
Type 1: Capitation plans (Denplan)
A capitation plan is a private arrangement between you and your dentist. You pay your dentist a fixed monthly fee, and in return they provide all agreed dental treatment as needed throughout the year.
The key feature is the monthly fee is set based on your individual oral health. If your teeth are in good condition, you pay less. If you have existing issues that are likely to need treatment, you pay more.
There are no claims, no annual limits, and no administrative process. If you need a filling, you simply book an appointment. There is no separate charge for that filling — it is covered by your monthly fee.
Example: Denplan Care at £17/month covers check-ups, hygiene appointments, fillings, crowns, root canals, and extractions as needed throughout the year.
The catch: You can only use a dentist who is registered with Denplan. You cannot sign up online — your dentist registers you when they carry out an initial assessment.
Type 2: Health cash plans (Simplyhealth, Westfield Health)
A health cash plan works like a cashback system. You pay a monthly premium directly to the plan provider (not your dentist). When you have dental treatment — at any NHS or private dentist — you pay upfront and then claim back a set amount.
Annual cashback limits apply per treatment type. For example, a plan might give you up to £150 cashback per year on dental treatment. If your treatment costs £80, you claim back £80. If it costs £300, you only get £150 back.
Advantages: No dentist restrictions, covers NHS and private treatment, claim from day one, easy online signup.
Limitations: Annual limits mean high-cost treatment may not be fully covered. The cashback model means you still pay upfront.
Type 3: Dental insurance (BUPA, Boots, WPA)
Dental insurance works like other forms of insurance. You pay monthly premiums and, if you need treatment, you submit a claim to the insurer who pays the dental practice directly (or reimburses you) up to your annual policy limits.
Dental insurance typically includes emergency cover, often with worldwide emergency cover on higher tiers. It may cover more complex treatments than a basic cash plan.
Key difference from capitation: Annual claim limits apply. Once you hit your annual limit (e.g. £1,000 per year), you pay the rest yourself.
Waiting period: Most dental insurance products apply a 2 to 3 month waiting period for routine treatment. Emergency cover is usually immediate.

Frequently asked questions
What are the three types of dental cover in the UK?
There are three main types. A capitation plan (such as Denplan) is a fixed monthly fee paid to your own dentist who then provides agreed treatment as needed, with no claims or annual limits. A health cash plan (such as Simplyhealth or Westfield Health) pays you cashback on treatment at any dentist up to annual limits. Dental insurance (such as BUPA, Boots or WPA) pays out against claims up to annual limits and usually includes emergency cover.
Do I need a dentist before signing up for a dental plan?
It depends on the type. A capitation plan like Denplan must be set up through a registered member dentist who assesses your oral health first — you cannot join online. Health cash plans and dental insurance have no dentist restriction and you can usually sign up online immediately.
Which type of dental cover is cheapest?
Health cash plans are usually the cheapest entry point, with premiums from around £5 per month. Dental insurance typically starts from around £8 per month, and capitation plans such as Denplan Care are generally £15–£22 per month because they cover all agreed treatment with no annual limit.
Do dental plans have annual limits?
Capitation plans like Denplan have no annual limits on covered treatment — your monthly fee covers it. Health cash plans and dental insurance both apply annual limits, so once you reach the cap (for example £150 cashback or a £1,000 insurance limit) you pay the rest yourself.
Is there a waiting period before I can claim?
Health cash plans typically let you claim from day one. Dental insurance usually applies a 2 to 3 month waiting period for routine treatment, though emergency cover is normally immediate. Capitation plans have no waiting period once you are enrolled, but enrolment requires an initial dentist assessment.
