NHS vs Private Dentist in London: The Honest Comparison

The choice between NHS and private dentistry in London is, for many people, not really a choice at all. Around 97% of people without an existing NHS dentist who tried to register with one were turned away, according to ONS data. Private dentistry is often the only realistic option for new patients in London.

But understanding the differences matters – both to make the best of whichever you can access, and to know when paying privately is genuinely worth the extra cost.

Key things to know:

• NHS Band 3 (£326.70) covers crowns, bridges, and dentures that would cost £600-£2,500 privately – exceptional value if you can access it
• Around 97% of people trying to register with a new NHS dentist in London are unsuccessful
• Private dentistry offers faster access, longer appointments, and a wider range of treatment options
• NHS and private treatment can be mixed at the same practice – some treatments can be done privately while keeping NHS for clinical care
• Dental plans (£15-40/month) can spread the cost of private routine care and represent good value if you attend regularly
• Quality is not inherently lower on the NHS – the constraints are time, materials, and the range of available treatments
• Cosmetic treatments (whitening, veneers, implants, Invisalign for adults) are private only regardless of where you are registered

Cost comparison: NHS vs private in London

NHS charges are fixed nationally (England, 2026). Private prices are approximate London ranges – see our full London dental costs guide for more detail.

The real cost advantage of NHS dentistry

The NHS Band 3 charge of £326.70 covers an extraordinary range of complex treatment – crowns, bridges, full dentures – that would cost thousands privately. If you can access an NHS dentist, this represents exceptional value.

The challenge is access. Almost one in five people in England who tried to get an NHS dental appointment recently were unsuccessful. In London, the structural shortage is acute despite the capital having more dentists per head of population than most of England – demand simply far exceeds supply.

What private dentistry actually gives you

Private dentistry is not just about the treatments unavailable on the NHS (whitening, implants, clear aligners). It also offers genuine practical advantages for routine care:

• Access. Private practices are generally able to offer new patient appointments within days or weeks, not months or years.
• Appointment length. Private appointments typically run 30-45 minutes for a check-up. NHS appointments are often 10-15 minutes. More time means more thorough assessment and more opportunity to ask questions.
• Continuity. Private practices are more likely to assign you a named dentist who sees you consistently over time and builds a proper picture of your dental history.
• Treatment options. Private dentistry gives you access to premium materials, specialist referrals, cosmetic options, and technologies not routinely available on the NHS.
• Booking flexibility. Many London private practices offer early morning, evening, and weekend appointments. NHS practices rarely do.

Is NHS treatment lower quality than private?

Not inherently, no. The dentist’s clinical skills are the same regardless of which system they are working within. A good NHS dentist provides excellent care. The constraints are time (shorter appointments), materials (NHS uses functional but not necessarily premium options), and the range of treatments available.

Where private care can make a genuine clinical difference is in appointment thoroughness, access to specialist care, and the ability to choose premium materials – for example, a ceramic crown vs an NHS standard crown, or a specialist endodontist for a complex root canal rather than a general dentist.

Can you mix NHS and private treatment?

Yes. If you are registered with an NHS dentist, you can have some treatments done privately (such as whitening or cosmetic bonding) while keeping NHS treatment for clinical care like fillings and extractions. Your dentist should be clear about what is NHS and what is private – they are legally required to tell you the cost before starting any treatment.

Some practices are entirely private. Others offer both NHS and private treatment. Check a practice’s NHS status on its listing in our directory.

Dental plans and insurance

Dental plans (such as Denplan) allow you to spread the cost of private dental care as a monthly payment. Typically covering routine check-ups, hygienist visits, and X-rays – with a discount on further treatment – plans usually cost £15-40 per month and offer good value if you attend regularly. Dental insurance works differently: you pay a monthly premium and claim costs back. Be aware that most policies have waiting periods and exclusions for pre-existing conditions, so read the small print before signing up.

Where to find your dentist in London

Browse our NHS dentists London hub to find practices currently accepting new NHS patients, or search by borough or treatment to find private practices near you. Our London dental costs guide has full private pricing across all common treatments.

The honest summary: if you can access an NHS dentist in London, it is worth holding onto that registration. The value for anything beyond a basic check-up is significant. If you cannot – and most people trying to register in London cannot – private dentistry with a good practice that gives you time and continuity of care is the realistic alternative. Use our directory to find rated practices near you, and do not let cost concerns put off routine care: the price of catching a problem early is almost always far less than the price of treating it late.
