I have a real phobia of dentists. It's so bad that today, I went for my first check up in over 23 years 

I needed to take the dc's and thought I should "man up" and get checked. I was a bit if a wreck. Even for a check up and x-Ray 
Anyway, unsurprisingly, I do have some decay in one of my back teeth and need a filling. I can either go to the dentist I saw today and have it done in the usual way (local anaesthetic in the gum) or I can be referred to another practice and be sedated.
Both options fill me with dread tbh. In practical terms, the referral means I'll need someone to drive me home and I won't be able to work/drive etc for 24 hours after. I also liked the dentist I saw today and felt comfortable (ish) with her. Just the thought of being fully awake and having dental work done fills me with dread.
I know I sound utterly pathetic. I'm a 40 year old reasonably intelligent woman FFS. I've had 10lb + babies with no pain relief. I'm not generally such a twat. Honestly 
Can anyone relate or offer any advice or experiences please?
