Please don't feel that your fears are silly - everyone's different with different fears and different reasons.
Like happy, I'm also an NHS patient. Whilst it's true that mainstream NHS practices usually spend less time per patient than private ones (too much pressure to treat as many patients as possible), a lot of it is also to do with the individual dentist's ability to make you feel more at ease and in control etc. For example, when I decided to go back after 7 years, the dentist I saw was fairly laid back and I never felt rushed or anything (even though I wanted to get out of there asap!). He's since retired and his replacement couldn't be more different - although my appointments are still the same length, he rushes about like a cat on a hot tin roof and things are very hurried! (I secretly suspect that he could be as nervous of me as I am of him!).
Don't beat yourself up over not being able to pick up the phone yet - you'll do it when you're ready (or maybe you could email them for an appointment?)
