Dentist, hair and eye appointments.... ADVICE NEEDED

Hi again. I need a few little pieces of advice on how to cope with the dentist, hair cuts, and eye appointments. 

I think I have sussed out hair appointments. So mainly dentist and eyes are the problem. We haven't been to the dentist for a couple of years due to covid but it's been booked for my kids in the half term. I've told my kids about it and my daughter does not want to go. My other children aren't a fan either. I mean who is, and on the day, they don't want to go into the room. It causes her anxiety and she hates all of it. I don't know how to cope with it. She tried to do a runner last time which I don't want it to happen again. It's just the average check-up. 

How do you cope with eye appointments. She likes part of it, where you have to read the letters but that's it. She doesn't like it when you have the light shining in her eyes. I need advice. 

Thanks again
