Here's a better idea: don't do that
If I feed in 15 crown/root canal invoices into AI asking it it's opinion, it will tell me I have a very bad mouth. This does nothing to inform me, and will lead to the expected AI response of: "Here are some practices in your area specializing in oral surgery".
There's a reason it's advised by doctors to not share health information. practices/doctors proscribe a regimen/treatment plan, and have to assume in good faith the patient will follow it. Imagine if every doctor heard "Well, AI told me..."
This is just blatantly made up. This doesn't even slightly resemble something an LLM would say
