How to Get a Second Opinion on a Dental Treatment Plan

You’ve just been handed a quote for £4,000 of dental work, or an NHS form with “Band 3” circled, and something about it doesn’t feel right. Maybe the number is bigger than you expected. Maybe the dentist rushed the explanation. Maybe you only went in because of one sore tooth and came out with a plan covering six.

You can get a second opinion, and you don’t have to explain why. No law, NHS contract or professional rule requires you to go ahead with the first plan you’re offered, and no dentist is entitled to your treatment because they examined you first. A second opinion also costs much less than most people assume, especially if you bring your records with you instead of starting from scratch.

This guide covers how to get those records, how to make your plan readable (with help from tools like ChatGPT, Claude or Gemini), and how to present everything so the second dentist is quoting for the same work as the first.

Your records are yours to ask for, and asking is free

Under UK GDPR, you have the right to a copy of the personal data a dental practice holds about you. That includes your clinical notes, charting, X-rays and treatment plan. This is called a subject access request (SAR). The practice:

• usually can’t charge you for it (a fee is only allowed if the request is “manifestly unfounded or excessive”, and asking once for your own records is neither)
• must respond within one calendar month
• can send the records digitally, which is normal for X-rays these days

Lots of practices will just email the X-rays the same day if you ask at reception. If they’re slow or vague, put it in writing. Here’s a version you can copy:

Subject: Subject access request – [Your full name], DOB [dd/mm/yyyy]

Dear Practice Manager,

Under Article 15 of the UK GDPR, I am requesting copies of the
following records held about me:

1. All radiographs (X-rays) taken in the last 3 years, in their
   original digital format (e.g. DICOM or full-resolution JPEG)
2. My most recent periodontal charting, including BPE scores
3. Clinical notes from my examination on [date]
4. The written treatment plan and itemised cost estimate issued
   on [date]

Please send these electronically to [email address].
I understand you have one month to respond.

Kind regards,
[Name]

Ask for the X-rays specifically in original resolution. A photo of a monitor, or a compressed thumbnail pasted into a PDF, is much harder for the second dentist to read.

Why the records cut the cost

A second-opinion appointment at a private practice in the UK usually costs between £40 and £120 for the examination. Several practices advertise free or discounted second-opinion consultations to win new patients, particularly for implant and orthodontic work.

X-rays are where costs grow. Without your existing images, the new dentist may want to take their own:

Turn up with no records and you could pay £95 for the exam, £50 for two bitewings and £70 for an OPG, which comes to £215. Turn up with recent X-rays and a clear plan and the same visit might be £60. You also avoid an unnecessary radiation dose, which is a perfectly good reason in itself. A dentist can still take new images if the old ones are out of date or don’t show what they need, but it shouldn’t be the default.

If you’re on the NHS, things work differently. A new NHS practice will do its own Band 1 examination (£27.40 in England under the April 2025 rates, though check nhs.uk for the current figure), and any X-rays it needs are included in that charge. Bringing your records still helps, because the dentist can compare old and new images and see whether something is actually getting worse.

Decode the plan before anyone else reads it

Dental plans are written in shorthand. Here’s a real-world style line from a private estimate:

UR6  RCT (molar)              £650
UR6  E-max crown              £850
LL6  XLA                      £150
LL6  Implant + abutment + crown  £2,400
UL4, UL5  Comp MOD            £120 each
     Hygiene (PMPR)           £75
                         Total: £4,365

This is where an AI tool actually earns its keep. Remove your name, date of birth and NHS number first, then paste the plan into ChatGPT, Claude or Gemini with a prompt like this:

I'm a UK dental patient with no clinical background. Below is my
private treatment plan. For each line, tell me:
- which tooth it refers to, in plain English
- what the procedure involves
- whether the price is low, typical or high for UK private dentistry
- what questions I should ask a second dentist about it

Do not tell me whether I need the treatment. Just help me understand it.

[paste plan]

You’ll get a translation. UR6 is the upper right first molar (sixth tooth back from the centre). RCT is root canal treatment. XLA means extraction. “Comp MOD” is a white filling that covers three surfaces of the tooth (mesial, occlusal, distal). PMPR is a professional clean.

Keep that last instruction in the prompt. A chatbot can’t see your mouth or your X-rays the way a dentist can, and it will happily make confident guesses if you let it. Use it as a translator and a price sanity-check, not as a diagnosis.

On price, AI answers drift, so cross-check anything that looks off. A molar root canal at £650 is mid-range for a general dentist. Specialist endodontists often charge £900–£1,400. A single implant with crown for £2,400 is towards the lower end of the UK range (£2,000–£3,500 is common), which is worth knowing: low implant prices sometimes leave out the bone graft or the final crown and add them later.

Watch for the notation trap

UK dentists use two numbering systems, and mixing them up will ruin a comparison.

• Palmer notation: quadrant plus a number from 1 to 8. UR6 = upper right, sixth tooth.
• FDI notation: two digits. The first digit is the quadrant (1 upper right, 2 upper left, 3 lower left, 4 lower right), and the second is the tooth. So UR6 is 16 and LL6 is 36.

If practice A writes “UR6” and practice B writes “26”, those are different teeth (upper right versus upper left). Before comparing quotes, rewrite both plans in the same system. Ask the AI to do it: “Convert this plan into FDI notation and list each tooth once with all procedures against it.” Then check the result against a tooth chart yourself, because a slip here costs real money.

Present it so the second dentist compares like for like

The worst kind of second opinion is a fresh exam where the new dentist writes a completely different plan and you’re left with two documents that don’t line up. Prevent that by bringing a single page that looks like this:

Hand this over at the start of the appointment along with the X-rays (on a USB stick or emailed ahead) and the original plan. Then say one sentence: “I’d like your independent view on each of these, and a price for anything you’d do the same way.”

That framing matters. It tells the dentist you aren’t shopping for a cheaper copy of someone else’s plan. You want their clinical judgement, tooth by tooth, which makes disagreements obvious. Maybe they’d also extract 36 but suggest a bridge for £1,100 rather than an implant. Maybe they think 24 and 25 can be monitored for a year. Either way, you’ll be able to see it in the table instead of digging it out of two differently formatted PDFs.

Worked example: what the difference can look like

Take the plan above. The patient sends a SAR on a Monday, gets the X-rays by email on Wednesday, and books a £60 second-opinion appointment the following week.

The second dentist agrees about 16. They look at the 36 periapical and say the roots are sound enough to try a root canal first, at £700 plus £750 for a crown, with extraction and an implant kept as the fallback if it fails. They think 24 is fine and only 25 needs a filling.

That’s a difference of £1,275 for £60 and a few emails. More importantly, the patient keeps a natural tooth. Not every second opinion will save money (sometimes the second dentist confirms the first plan line for line, which is valuable in its own way, because you can go ahead knowing it’s sound).

NHS plans have their own paperwork

If your plan is NHS in England, you should have received a FP17DC form (the personal dental treatment plan) for any Band 2 or Band 3 course of treatment. It lists the treatments and the band charge. You’re entitled to a copy. Bring it to the second practice.

Two things trip people up here. First, NHS practices sometimes offer some items privately within a mixed plan (“the white filling on a back tooth would be private”). The FP17DC should show which is which, so check it. Second, a Band 3 charge is the same whether you have one crown or four, so with NHS plans the question is less about price and more about whether the treatment itself is right.

Finding an NHS practice taking new patients is still hard in many areas. If you need help shortlisting somewhere to get that second view, our guide to choosing a dentist covers how to check registration, read reviews properly and spot practices that rely on high-pressure selling.

If the first practice reacts badly

Most dentists are completely relaxed about second opinions, and good ones encourage them for big-ticket work. If a practice delays your records past the one-month deadline, demands a fee for a simple request, or pressures you to sign before you’ve had time to think, you have options. For a SAR that goes unanswered, you can complain to the Information Commissioner’s Office. For private treatment disputes, the Dental Complaints Service (run with the General Dental Council) handles complaints free of charge. NHS complaints go to the practice first, then the Parliamentary and Health Service Ombudsman if they’re not resolved.

You probably won’t need any of that. One polite email, a free copy of your X-rays and a £60 appointment is usually enough to find out whether the plan in your hand is the right one.
