Asking AI About Your Teeth

You’ve left the surgery with a printed plan full of abbreviations, a total at the bottom, and a receptionist asking when you’d like to book. Maybe it says “Band 3, £326.70”. Maybe it’s a private quote for £4,000 or more. You probably didn’t ask much in the chair, and now you’re at home, typing the whole thing into ChatGPT.

That’s a reasonable thing to do. Large language models are good at explaining jargon, laying out options and catching price lines that look odd. They can’t examine your mouth, and they get some UK-specific details badly wrong. This page explains how to get useful ChatGPT dental advice on a plan you already have: which documents to collect, how to write the prompts, how to check what comes back, and where to stop relying on it.

What AI can and can’t tell you about a treatment plan

Think of ChatGPT, Claude, Gemini or Microsoft Copilot as a well-read friend who has never seen your teeth. That friend can tell you what “LL6 MOD composite” means, why a root-filled molar usually needs a crown, and whether £950 is a normal private fee for molar root canal treatment in the UK. They can’t tell you whether your LL6 actually needs that filling.

Here’s how the work splits:

Most people come unstuck with that last row. A model that has just explained root canal treatment clearly will go on to say “this sounds necessary” in the same calm tone, even though it has nothing to base that on.

Collect the paperwork before you open ChatGPT

How good the answer is depends on what you give the model. “My dentist wants to do a root canal and crown, is £1,700 fair?” will get you a vague reply. Paste in the actual itemised plan and you’ll get a detailed one.

Ask the practice for these:

1. The written treatment plan. In England, NHS patients should get a written plan (the form is usually called an FP17DC) for any Band 2 or Band 3 course. It lists each item and says whether it’s NHS or private. Private practices nearly always print an itemised estimate.
2. Tooth numbers for every item. UK dentists use two systems. Palmer notation splits the mouth into four quarters and numbers each tooth from the middle outwards: UR6 means upper right, sixth tooth back (the first molar). Practice software often uses FDI notation instead, where the same tooth is 16. If your plan just says “crown, back tooth”, ask which one.
3. Your BPE score. This is a six-box gum health grid, scored 0 to 4 (and sometimes *). It explains why a plan might include several hygiene visits.
4. Copies of your X-rays. Under UK GDPR you can make a subject access request for your dental records, X-rays included. It’s free in almost all cases, and the practice has one month to reply. Whether an AI can actually read those images is a separate, more complicated question, covered in Can ChatGPT Read Your Dental X-Ray?. The short answer is that the written report from the dentist is far more useful to paste in than the image.

Before you paste anything, remove your name, date of birth, address and NHS number. The model doesn’t need them. In ChatGPT, go to Settings, then Data Controls, and switch off “Improve the model for everyone” if you don’t want your chats used for training. You can also use a Temporary Chat. Claude and Gemini have similar controls in their privacy settings.

Decoding the shorthand

Dentists write plans for other dentists and for the software, not for patients. Here are the abbreviations you’ll see most, so you can check whether the AI’s explanation is right:

The surface letters are the main reason to ask for an itemised plan. An “O” filling on a molar is small. An “MODB” filling covers four surfaces of the same tooth and leaves so little natural tooth that some dentists will later suggest a crown. Once you know that, you understand why a crown might come up at your next check-up.

Worked example: an NHS Band 3 plan in England

Here’s an anonymised plan of a kind England practices print all the time:

Course of treatment: NHS Band 3      Patient charge: £326.70
UL6  RCT (3 canals)                  NHS
UL6  Crown, PFM                      NHS
LR5  MO amalgam                      NHS
S&P                                  NHS
Optional private items:
LR5  MO composite (white)            £145.00
UL6  E.max crown upgrade             £520.00

The patient wants to know what they’re paying for, and whether the upgrades are worth it.

This is the prompt to use:

I'm in England and have an NHS dental treatment plan. Please explain
each line in plain English, tell me which NHS charge band each item
falls into, and confirm what I'll pay in total if I accept only the
NHS items. Then explain what the two private options would change,
practically and cosmetically. Current England NHS charges from April
2025: Band 1 £27.40, Band 2 £75.30, Band 3 £326.70. Use UK terms and
pounds sterling.

[paste plan]

Including the current charges matters. Without them, models regularly quote the 2023 figures (£25.80, £70.70, £306.80) or older ones. Check the NHS website for the current year’s charges before you paste them in. Wales, Scotland and Northern Ireland each have their own charging systems, so state which nation you’re in.

You should get back roughly these points:

• RCT and fillings are Band 2 items. The crown makes the whole course Band 3. You pay £326.70 once for everything on the NHS list, not £326.70 plus £75.30.
• An NHS crown is provided when it’s clinically needed. Which material is used is the dentist’s clinical decision. For an upper first molar, metal-ceramic is a normal, durable choice.
• The £520 upgrade gets you a crown with no metal, which matters most if you can see that tooth when you smile widely. Many people can’t see their UL6. Some can.
• The £145 white filling on LR5 (a premolar, which shows more) is a cosmetic choice. In England, amalgam is still allowed for most adults on the NHS.
• If you need more Band 3 or lower treatment within two months of finishing this course, you shouldn’t pay again.

The total is either £326.70, or £991.70 with both upgrades. Before the AI helped, the patient probably didn’t realise those upgrades made up two-thirds of the possible bill, or that saying no to both still gets a complete, clinically sound course.

If the AI says something like “the NHS doesn’t cover root canals” or “NHS crowns are always metal”, it’s wrong. Root canal treatment is a standard Band 2 item. Point out the mistake and ask it to check again.

Worked example: a £5,030 private quote

Here’s a private quote from a practice in the south-east of England:

Here’s the prompt for this one:

I'm a private dental patient in south-east England (not London). Below
is an itemised quote. For each item, give a typical UK private fee
range in 2026 and say whether this fee is low, typical or high.
Then list anything commonly needed for these treatments that is NOT
on the quote and could add cost later. Then list what the nearest
NHS equivalent would cost me in England. Do not use US prices or
US insurance terms.

[paste table]

A careful model should come back with ranges something like this (UK private fees, outside central London):

Central London is often 20 to 40 percent higher than these ranges. Ask the AI to take that into account if that’s where you are.

The prices on their own are fine. The gaps and assumptions in the quote are where it gets interesting:

• What isn’t listed for the implant. Most implant plans need a CBCT scan (often £150 to £300). If there isn’t enough bone, a graft can add £400 to £900. There’s usually a healing wait of around three months between extraction and placement. Ask the practice whether £2,650 covers all of that.
• Why LR6 is coming out, but UR6 is being root-filled. Both are first molars. A good AI answer will tell you to ask why one is being saved and the other isn’t. There may be a perfectly good reason (a fracture through the root, or decay too far below the gum), but you should hear what it is.
• The alternatives to an implant. A bridge, a partial denture, or leaving the gap. A gap where a lower first molar was is sometimes acceptable if the other back teeth meet properly. Ask the dentist to talk you through each option.
• The NHS comparison. Leaving out the implant, almost everything else here (RCT, crown, filling, extraction, scale and polish) would come under a single NHS Band 3 charge of £326.70 in England. Privately, those same items cost £2,380 including the exam and X-rays. That doesn’t mean the private care is a rip-off. Private appointments are often longer, and you get more choice of materials. But you should know the gap is there before you sign, and you should know whether an NHS place is actually available to you locally. In many areas it isn’t, which is the reason a lot of people go private.

Prompts that get better answers

Three habits make a big difference to the quality of ChatGPT dental advice.

Tell it where you are and what sort of answer you want. “UK, England, private, pounds sterling, no US insurance terminology” stops the model drifting into talk of CDT codes, deductibles and “scaling and root planing” priced in dollars.

Ask for questions, not verdicts. “What should I ask my dentist about this?” gets far more useful answers than “Do I need this?” A model can’t know the second. It’s very good at the first.

Make it argue against itself. After its first answer, try:

Now argue the case that this treatment plan is reasonable and
well-priced as written. Then argue the case that I should get a
second opinion. Which specific facts on the plan would decide
between those two positions?

Models are agreeable by default. If you sound worried, they’ll pick up on it and agree that something seems off. Asking for both sides shows you which specific facts would actually settle the question.

You can also try this one for any single item you don’t understand:

Explain [UR6 RCT] as if I'll be sitting in the chair for it: how many
appointments, roughly how long each, whether I'll need anaesthetic,
what it feels like afterwards, and what the success rate is for a
first-time root canal on an upper molar. Say where the evidence is
uncertain.

That last sentence is worth adding to any medical prompt. It pushes the model to show where it’s unsure, which it usually won’t do unless you ask.

Where the tools reliably go wrong

After a lot of dental plans run through ChatGPT, Claude and Gemini, the same mistakes keep showing up.

US defaults are the most common. Fees come back in dollars, and terms like “periodontal maintenance” are explained as though insurance covers them. If you see a dollar sign or the word “copay”, start again and say you’re in the UK.

Out-of-date NHS charges come next. Even models that can search the web sometimes quote last year’s bands, which is why you should paste the current figures yourself.

Then there’s tooth-number confusion. In US numbering, “tooth 3” is the upper right first molar, but the US system is entirely different from Palmer and FDI. If your plan says “16” and the model talks about “tooth 16”, it may be thinking of a US wisdom tooth. Tell it you’re using FDI notation.

Then there’s false confidence with images. Upload a bitewing and ask “is there decay?” and a model will often produce a fluent, specific, made-up answer. Our test of ChatGPT on real dental X-rays goes through why this happens and what it can safely do with a radiograph (mostly explain the dentist’s written report).

The quietest failure is the missing alternative. Ask “Is an implant the best option?” and you’ll often get a description of implants with only a brief mention of bridges and dentures. Ask for all the alternatives directly, with typical UK costs and lifespans for each.

Turning the answer into a decision

When you’ve finished with the AI, sort each item on the plan into one of three groups.

Understood and accepted. You know what it is, why it’s needed and roughly what it should cost, and the quote fits. Book it.

Needs a question answered. You understand what it is, but something doesn’t add up: a missing cost, a choice that seems inconsistent, an alternative nobody mentioned. Most items end up here. Write the questions down and phone the practice or ask at your next appointment. A good dentist won’t mind. Five minutes on the phone about why LR6 can’t be saved is entirely normal.

Needs a second opinion. Get one when the total is large (several thousand pounds), when the plan is to remove a tooth that doesn’t hurt, or when the explanations don’t make sense to you even after you’ve asked. You can see a different dentist privately for a consultation, usually £50 to £120. Take your X-rays with you so you’re not paying for them again.

Before seeing anyone new, check them on the General Dental Council’s online register. If a plan includes specialist work, the register also shows whether that dentist is on a specialist list (endodontics, periodontics, prosthodontics, oral surgery, orthodontics). A general dentist charging specialist fees for root canal treatment is a fair thing to question.

Questions worth taking back to your dentist

These questions come up often enough to bring along. Ask the AI to adapt them to your own plan:

• What happens if I leave this tooth untreated for six months? And for two years?
• Is this tooth being saved, or is it coming out? What did you see that decided it?
• Does the implant price include the scan, any bone graft, and the final crown?
• If I go ahead with the NHS version, what exactly am I giving up?
• Who will do the root canal, and if it fails, what does a retreatment cost?
• Can the treatment be spread across two courses, and would that change what I pay?
• Is the hygienist plan because of my BPE score, and which boxes scored 3 or 4?

Write down the answers. Next time you open ChatGPT, paste them in alongside the original plan. A model working from your dentist’s actual reasons will give you far better ChatGPT dental advice than one guessing from a list of abbreviations.
