How to Share Your Dental Plan With AI Without Oversharing

Your dentist has handed you a treatment plan. It says something like “UR6 RCT, PFM crown, £1,240” and you have no idea whether that’s a fair price or even what half of it means. Pasting it into ChatGPT seems like the obvious next step, and it’s a sensible one. The AI doesn’t need to know who you are to explain it, though.

Most dental plans are printed on practice letterhead. Under the logo sit your full name, home address, date of birth, often your NHS number, and the name and GDC registration number of the dentist. None of that helps the AI explain a root canal. Take all of it out and the answer you get back is exactly as good.

Why the identifying details are worth removing

Concerns about ChatGPT privacy and medical information usually focus on dramatic scenarios like hacks and leaks. The everyday risk is duller than that. What you type into a chatbot gets stored, may be read by staff who review conversations, and depending on your settings may be used to train future models.

Here is what the main consumer tools do by default (as of autumn 2026; settings menus move around, so check before you rely on this):

That Gemini detail matters most. Google says a sample of conversations is read by human reviewers, and those reviewed chats are kept separately from your account. If yours gets picked, a stranger is reading a document with your name, birthday and the fact that you have gum disease.

UK GDPR treats health information as “special category” data, which is the most sensitive tier. Your dental plan counts. A plan with your name stripped off is just a description of some teeth. A plan with your name, date of birth and practice on it is a health record about you, and it’s sitting on a server in another country under terms you clicked through without reading.

You lose nothing by removing it. The AI can’t phone your dentist or look up your records, and it doesn’t need to know your age to the day. What it needs is the treatment.

What to remove and what to keep

Region is the one exception people get wrong in both directions. “Practice Name, 14 High Street, Guildford GU1” is too much, while saying nothing at all is too little, because private fees in central London can be 40% higher than in the North East. “South East England, town centre practice” gives the AI enough to judge the price without pointing to a particular building.

A worked example

Here is a typical private plan as it arrives:

Riverside Dental Care, 22 Bridge Street, Shrewsbury SY1 1QH
Patient: Sarah J. Whitcombe   DOB: 14/03/1981
Address: 7 Larch Close, Shrewsbury SY3 9PL
NHS No: 485 777 3456
Clinician: Dr A. Patel (GDC 123456)

Treatment Plan — Ref RDC-20931
1. Comprehensive examination           £65
2. 2x periapical radiographs           £30
3. UR6 root canal treatment (molar)    £650
4. UR6 porcelain-bonded-to-metal crown £595
5. Hygienist appointment               £75
Total                                  £1,415

Here is what to paste instead:

Private dental treatment plan, small town in Shropshire.
I'm a woman in my 40s, no medical conditions, no regular medication.

1. Comprehensive examination           £65
2. 2x periapical X-rays                £30
3. UR6 root canal treatment (molar)    £650
4. UR6 porcelain-bonded-to-metal crown £595
5. Hygienist appointment               £75
Total                                  £1,415

Please explain each item in plain English, tell me whether these prices
look normal for a private practice in the West Midlands, and list
questions I should ask before agreeing to it.

That took about forty seconds. The second version is actually the better prompt, because it asks for something specific and gives location context the first version only implied.

I ran the cleaned version through ChatGPT. It explained that UR6 means the upper right first molar, that a root canal on a molar is harder than on a front tooth because molars have three or four canals, and that a crown afterwards is standard because root-filled back teeth tend to crack. On price, it put the root canal within a typical UK private range of roughly £400 to £900 for a molar and the crown within £450 to £900. Then it suggested asking whether the root canal would be done by a general dentist or referred to an endodontist, whether the hygienist visit was required or optional, and what the success rate looks like if the tooth already has an infection.

It needed nothing it hadn’t been given, and your name wouldn’t have changed a word of the answer.

NHS plans: even less to share

NHS treatment in England is charged in three bands, so there’s no line-by-line price to check. In 2025/26 they were £27.40 for Band 1, £75.30 for Band 2 and £326.70 for Band 3 (check nhs.uk for this year’s figures, and note that Scotland, Wales and Northern Ireland use different systems). If your plan says Band 3 and lists a crown, the useful question for an AI isn’t about price at all. Ask something like:

NHS Band 3 plan in England: LL6 root canal and crown. The dentist has
also offered a private zirconia crown for £520 instead of the NHS one.
What's the actual difference, and is the upgrade worth it on a back tooth?

You don’t need your name, your NHS number or your practice to ask that. The “private upgrade” offer is one of the most common reasons people come to an AI with an NHS plan, and the answer depends on the tooth and the material. It doesn’t depend on who you are.

Photos and PDFs are the easiest way to overshare

Taking a photo of the printed plan and uploading it is tempting. ChatGPT, Claude and Gemini can all read a photographed document perfectly well, and that’s the trouble: they read the letterhead as well. A phone photo can also carry the location where you took it in its metadata, which for most people is their kitchen.

You have two better options. Type the treatment lines out yourself, which rarely takes more than a minute because most plans run to fewer than ten lines. Or, if it’s a PDF, copy just the treatment table and paste it as text. If you really do want to upload the file, cover the header with a sticky note before you photograph it, then check the photo before you send it.

Turn training off before you start

Removing personal details is the main protection. Changing the setting is a second one that costs nothing. On ChatGPT, open Temporary Chat from the model menu at the top of the screen, and that conversation won’t be saved to your history or used for training. If you’d rather keep the chat so you can come back to it after your next appointment, switch off “Improve the model for everyone” under Data controls instead. Either way you can still ask follow-up questions in the same session, such as “what if I wanted an implant instead of the crown?”

Once your plan is cleaned up, the next skill is asking questions that get useful answers rather than generic reassurance. Our guide to asking AI about your teeth covers how to word follow-ups, how to spot when a chatbot is guessing, and which questions you should take back to your dentist instead.

One thing to put back in

There’s one category of personal information you should add rather than remove: anything about your health that changes the treatment. If you take blood thinners, are pregnant, have diabetes, have had radiotherapy to your head or neck, or take bisphosphonates for osteoporosis, say so. Those details affect whether a procedure is safe and how it should be done, and leaving them out to protect your privacy gives you a worse answer for nothing. “On warfarin” tells the AI something that matters about your treatment. “Sarah Whitcombe, born 14 March 1981” only tells it who you are.
