Get Yourself Back to the Dentist After Years of Putting It Off

I haven't been to the dentist in [how long it's been, or rough last visit date] and I want to go back, but I keep putting it off. Help me get unstuck.

About me:
- The main reason I've been avoiding it: [cost / dental anxiety / can't find an NHS dentist / embarrassment about the state of my teeth / always too busy / something else]
- Where I live (town or postcode area): [town or postcode]
- NHS or private: [NHS / open to private / not sure yet]
- Any specific worries about my teeth or gums right now: [describe, or write 'nothing specific']
- Realistic budget for a first visit: [£amount, or 'NHS check-up only']

Please give me, in this order:
1. A short, kind reality check on what actually tends to happen at a first appointment after a long gap — what they'll do, what they won't do on day one, and the kinds of things dentists are genuinely used to seeing.
2. A simple step-by-step plan to find and register with a dentist in my area, including what to do if NHS practices nearby aren't taking on new patients.
3. A short script I can read out when I phone to register or book, so I don't fumble my words or talk myself out of it halfway through.
4. Three or four small things I can do in the week before the appointment to keep my anxiety manageable.
5. A short list of useful questions to ask at the appointment so I leave feeling informed rather than overwhelmed.

Keep your tone warm and non-judgemental. Do not lecture me about flossing or how long it's been. Use British English and UK terms (NHS, GP, £, etc.).
